It takes a bit of effort, but iPhones can wind up with viruses and malware. And that can indeed lead to all kinds of snooping.
Whether through malware or a bad app, hackers can skim personal info while you browse, bank, and shop. They can also infect your phone with ransomware that locks up your personal info or that locks up the phone itself.
Those are some worst-case scenarios. However, good for you and unfortunate hackers is the way iPhones run apps. It makes it tough for viruses and malware to get a toehold. Apple designed the iOS operating system to run apps in what’s called a “virtual environment.” This limits the access apps have to other apps, which helps prevent viruses and malware from spreading.
Still, malware can end up on an iPhone in a couple of ways:
The owner “jailbreaks” the iPhone
This practice gives people more control over their iPhones. By jailbreaking, they gain “root control” of the phone. With that, they can do things like remove pre-installed apps and download third-party apps from places other than the App Store. And that’s where the trouble can start.
Jailbreaking removes several of those barriers that keep viruses and malware from spreading. Further, downloading apps outside of the App Store exposes the phone to viruses and malware. Apple doesn’t review the apps in those stores. That way, a hacker with malicious intent can post a bad app with relative ease.
A malicious app sneaks into the App Store
Apple has a strict review policy before apps are approved for posting in the App Store. Per Apple, “Apple’s App Review team of over 500 experts evaluates every single app submission — from developers around the world — before any app ever reaches users. On average, the team reviews approximately 132,500 apps a week.”
However, bad actors find ways to sneak malware into the store. Sometimes they upload an app that’s initially innocent and then push malware to users as part of an update. Other times, they’ll embed malicious code such that it only triggers after it’s run in certain countries. They will also encrypt malicious code in the app that they submit, which can make it difficult for reviewers to sniff out.
So, barring a jailbroken phone, the chances of getting a virus or malware on your iPhone remain low. Still, it can happen.
Because we spend so much time on our phones, it’s fairly easy to tell when something isn’t working quite like it is supposed to. While you can chalk up some strange behavior to technical issues, sometimes those issues are symptoms of an infection. Malware can eat up system resources or conflict with other apps on your phone, causing it to act in odd ways.
Some possible signs that your device has been hacked include:
Performance issues
A slower device, webpages taking way too long to load, or a battery that never keeps a charge are all things that can be attributed to a device reaching its retirement. However, these things might also be signs that malware has compromised your phone.
Your phone feels like it’s running hot
Malware running in the background of a device might burn extra computing power, causing your phone to feel hot and overheated. If your device is quick to heat up, it might be due to malicious activity.
Mysterious calls, texts, or apps appear
If apps you haven’t downloaded suddenly appear on your screen, or if outgoing calls you don’t remember making pop up on your phone bill, that is a definite red flag and a potential sign that your device has been hacked.
Changes or pop-ups crowd your screen
Malware might also be the cause of odd or frequent pop-ups, as well as changes made to your home screen. If you are getting an influx of spammy ads or your app organization is suddenly out of order, there is a big possibility that your phone has been hacked.
To avoid the hassle of having a hacked phone in the first place, here are some tips that can help.
Promptly updating your phone and apps is a primary way to keep your device safer. Updates often fix bugs and vulnerabilities that hackers rely on to download malware for their attacks.
Apple’s App Store has those protections in place that we mentioned before. That’s unlike those third-party sites, which might not have those same protections. Further, some purposely host malicious apps. Avoiding these sites altogether can prevent these apps from allowing hackers into your device.
As we’ve seen, jailbreaking a phone introduces all kinds of security issues. Your best bet as an everyday internet user is to rely on iOS and the protections that come with it.
If you are worried that your device has been hacked, follow these steps:
Completely power down your phone. Powering down and then giving your phone a fresh start can put a halt to any malicious activity.
Remove any apps you didn’t download. From there, power down your phone and restart it as before.
If you still have issues, wiping and restoring your phone is an option. Provided you have your photos, contacts, and other vital info backed up in the cloud, it’s a relatively straightforward process. A quick search online can show how to wipe and restore your model of phone.
Check your accounts and credit for any unauthorized purchases. Several features in our McAfee+ plans can help. Identity Monitoring can alert you if your info winds up on the dark web. Our Credit Monitoring along with our transaction monitoring can also alert you of unusual activity across your accounts.
Lastly, if you spot an issue, get some help from a pro. Our Identity Theft Coverage & Restoration service offers $2 million that covers travel, losses, and legal fees associated with identity theft. It also offers the services of a licensed recovery pro who can repair your credit and your identity in the wake of an attack.
On a non-jailbroken phone, no. You don’t need antivirus. Yet your phone should certainly get extra protection. Phones face far more threats than viruses and malware alone.
Comprehensive online protection software like ours can keep you and your phone safer. It can:
Those are only a handful of the many features that protect more than your phone. You’ll find yet more that protect you — namely, your identity and your privacy.
So while iPhones don’t need antivirus, they certainly benefit from extra online protection.
The post How To Tell If Your Smartphone Has Been Hacked appeared first on McAfee Blog.
“My phone’s been hacked!” Words you probably don’t want to hear or say. Ever.
Yes, a smartphone can get hacked just like any other device. And they make prize targets as well. Loaded as they are with personal and financial information, access to payment apps, files, photos, and contacts, bad actors have plenty to gain by tapping into your smartphone.
How do bad actors pull it off? They have several attack vectors they can choose from.
Today’s attackers have gotten cagier as well. It used to be that a hacked phone would run sluggishly or hot after it got infected by malware. The battery might have drained quickly as well. That was because the malware ate up system resources, created conflicts with other apps, and used your data or internet connection to pass along your personal information—all of which could make your smartphone feel a little off. That still might be the case with some mobile malware today, yet much of it works far more efficiently. The old telltale physical signs of a hacked phone might not present themselves at all.
However, you can spot several indications that might indicate your phone has been hacked.
A few examples follow. Note that these might be signs of a hacked phone, yet not always.
Install and run online protection software on your smartphone if you haven’t already. From there, delete any apps you didn’t download, delete risky texts, and then run your mobile security software again.
If you still have issues, wiping and restoring your phone is an option. Provided you have your photos, contacts, and other vital info backed up in the cloud, it’s a relatively straightforward process. A quick search online can show how to wipe and restore your model of phone.
Lastly, check your accounts and your credit card statements to see if any unauthorized purchases have been made. If so, you can go through the process of freezing those accounts and getting new cards and credentials issued. Further, update your passwords for your accounts with a password that is strong and unique to prevent further theft.
To help keep your phone from getting hacked in the first place, there are a few relatively easy steps you can take. Inside of a few minutes, you can find yourself much safer than you were before.

When we come across the term Artificial Intelligence (AI), our mind often ventures into the realm of sci-fi movies like I, Robot, Matrix, and Ex Machina. We’ve always perceived AI as a futuristic concept, something that’s happening in a galaxy far, far away. However, AI is not only here in our present but has also been a part of our lives for several years in the form of various technological devices and applications.
In our day-to-day lives, we use AI in many instances without even realizing it. AI has permeated into our homes, our workplaces, and is at our fingertips through our smartphones. From cell phones with built-in smart assistants to home assistants that carry out voice commands, from social networks that determine what content we see to music apps that curate playlists based on our preferences, AI has its footprints everywhere. Therefore, it’s integral to not only embrace the wows of this impressive technology but also understand and discuss the potential risks associated with it.

AI, a term that might sound intimidating to many, is not so when we understand it. It is essentially technology that can be programmed to achieve certain goals without assistance. In simple words, it’s a computer’s ability to predict, process data, evaluate it, and take necessary action. This smart way of performing tasks is being implemented in education, business, manufacturing, retail, transportation, and almost every other industry and cultural sector you can think of.
AI has been doing a lot of good too. For instance, Instagram, the second most popular social network, is now deploying AI technology to detect and combat cyberbullying in both comments and photos. No doubt, AI is having a significant impact on everyday life and is poised to metamorphose the future landscape. However, alongside its benefits, AI has brought forward a set of new challenges and risks. From self-driving cars malfunctioning to potential jobs lost to AI robots, from fake videos and images to privacy breaches, the concerns are real and need timely discussions and preventive measures.
AI has made it easier for people to face-swap within images and videos, leading to “deep fake” videos that appear remarkably realistic and often go viral. A desktop application called FakeApp allows users to seamlessly swap faces and share fake videos and images. While this displays the power of AI technology, it also brings to light the responsibility and critical thinking required when consuming and sharing online content.
→ Dig Deeper: The Future of Technology: AI, Deepfake, & Connected Devices
Yet another concern raised by AI is privacy breaches. The Cambridge Analytica/Facebook scandal of 2018, alleged to have used AI technology unethically to collect Facebook user data, serves as a reminder that our private (and public) information can be exploited for financial or political gain. Thus, it becomes crucial to discuss and take necessary steps like locking down privacy settings on social networks and being mindful of the information shared in the public feed, including reactions and comments on other content.
McAfee Pro Tip: Cybercriminals employ advanced methods to deceive individuals, propagating sensationalized fake news, creating deceptive catfish dating profiles, and orchestrating harmful impersonations. Recognizing sophisticated AI-generated content can pose a challenge, but certain indicators may signal that you’re encountering a dubious image or interacting with a perpetrator operating behind an AI-generated profile. Know the indicators.
With the advent of AI, cybercrime has found a new ally. As per McAfee’s Threats Prediction Report, AI technology might enable hackers to bypass security measures on networks undetected. This can lead to data breaches, malware attacks, ransomware, and other criminal activities. Moreover, AI-generated phishing emails are scamming people into unknowingly handing over sensitive data.
→ Dig Deeper: How to Keep Your Data Safe From the Latest Phishing Scam
Bogus emails are becoming highly personalized and can trick intelligent users into clicking malicious links. Given the sophistication of these AI-related scams, it is vital to constantly remind ourselves and our families to be cautious with every click, even those from known sources. The need to be alert and informed cannot be overstressed, especially in times when AI and cybercrime often seem to be two sides of the same coin.
As homes evolve to be smarter and synced with AI-powered Internet of Things (IoT) products, potential threats have proliferated. These threats are not limited to computers and smartphones but extend to AI-enabled devices such as voice-activated assistants. According to McAfee’s Threat Prediction Report, these IoT devices are particularly susceptible as points of entry for cybercriminals. Other devices at risk, as highlighted by security experts, include routers, and tablets.
This means we need to secure all our connected devices and home internet at its source – the network. Routers provided by your ISP (Internet Security Provider) are often less secure, so consider purchasing your own. As a primary step, ensure that all your devices are updated regularly. More importantly, change the default password on these devices and secure your primary network along with your guest network with strong passwords.
Having an open dialogue about AI and its implications is key to navigating through the intricacies of this technology. Parents need to have open discussions with kids about the positives and negatives of AI technology. When discussing fake videos and images, emphasize the importance of critical thinking before sharing any content online. Possibly, even introduce them to the desktop application FakeApp, which allows users to swap faces within images and videos seamlessly, leading to the production of deep fake photos and videos. These can appear remarkably realistic and often go viral.
Privacy is another critical area for discussion. After the Cambridge Analytica/Facebook scandal of 2018, the conversation about privacy breaches has become more significant. These incidents remind us how our private (and public) information can be misused for financial or political gain. Locking down privacy settings, being mindful of the information shared, and understanding the implications of reactions and comments are all topics worth discussing.
Awareness and knowledge are the best tools against AI-enabled cybercrime. Making families understand that bogus emails can now be highly personalized and can trick even the most tech-savvy users into clicking malicious links is essential. AI can generate phishing emails, scamming people into handing over sensitive data. In this context, constant reminders to be cautious with every click, even those from known sources, are necessary.
→ Dig Deeper: Malicious Websites – The Web is a Dangerous Place
The advent of AI has also likely allowed hackers to bypass security measures on networks undetected, leading to data breaches, malware attacks, and ransomware. Therefore, being alert and informed is more than just a precaution – it is a vital safety measure in the digital age.
Artificial Intelligence has indeed woven itself into our everyday lives, making things more convenient, efficient, and connected. However, with these advancements come potential risks and challenges. From privacy breaches, and fake content, to AI-enabled cybercrime, the concerns are real and need our full attention. By understanding AI better, having open discussions, and taking appropriate security measures, we can leverage this technology’s immense potential without falling prey to its risks. In our AI-driven world, being informed, aware, and proactive is the key to staying safe and secure.
To safeguard and fortify your online identity, we strongly recommend that you delve into the extensive array of protective features offered by McAfee+. This comprehensive cybersecurity solution is designed to provide you with a robust defense against a wide spectrum of digital threats, ranging from malware and phishing attacks to data breaches and identity theft.
The post AI & Your Family: The Wows and Potential Risks appeared first on McAfee Blog.
PayPal recently notified thousands of its customers that their accounts were breached by hackers, leaving their Social Security Numbers and other key pieces of personal information exposed as a result.
Sources report, that the attack involved “credential stuffing,” where hackers gather lists of usernames and passwords sourced from the dark web or from data breaches—and then “stuff” those credentials into login systems, giving them access to those accounts.
This form of attack is particularly dangerous for people who re-use passwords across their accounts, as hackers can steal a password from one account and use it to access others.
It is reported that PayPal notified users affected by this attack on January 18th with an email since made available online. The email states that,
“Based on PayPal’s investigation to date, we believe that this unauthorized activity occurred between December 6, 2022, and December 8, 2022, when we eliminated access for unauthorized third parties. During this time, the unauthorized third parties were able to view, and potentially acquire, some personal information for certain PayPal users.”
PayPal further detailed the information exposed (emphasis ours):
The personal information that was exposed could have included your name, address, Social Security number, individual tax identification number, and/or date of birth.
The email went on to say that PayPal reset the passwords of the affected accounts and will require affected users to establish a new password the next time they log in to their accounts.
It takes time for companies to discover breaches and other illegal activities on their networks. The activity may have occurred days, weeks, or even months before it was discovered. Thereafter, it takes yet more time for companies to investigate the attack, determine the method of entry, what was affected, and to what extent—not to mention update their security measures as needed.
In the case of PayPal, the company stated that the attacks occurred between December 6th and 8th of 2022, and the notification sent to affected customers was dated January 18th.
This is typical of such attacks. Time passes before victims get notified. And yet more victims may be identified as investigations continue, leaving hackers with a relatively large window of opportunity to do harm.
Given the nature of the PayPal attack, there are a few steps you can take to protect yourself in its aftermath, which involves a combination of preventative steps and some monitoring on your part.
Given that passwords were involved, changing your PayPal password is a must. (As stated, PayPal will require you to do so.) And if you re-use passwords or similar passwords across accounts, changing them is a must as well.
Strong and unique passwords are best, which means never reusing your passwords across different sites and platforms. Using a password manager will help you keep on top of it all, while also storing your passwords securely. Moreover, changing your passwords regularly may make a stolen password worthless because it’s out of date by the time a hacker attempts to use it.
While a strong and unique password is a good first line of defense, enabling two-factor authentication across your accounts will help your cause by providing an added layer of security. It’s increasingly common to see nowadays, where banks and all manner of online services will only allow access to your accounts after you’ve provided a one-time passcode sent to your email or smartphone.
PayPal offers two-factor authentication as an option, and you can enable it by logging into your account settings and then clicking on the “Security” tab.
Per PayPal’s customer email, contact their customer service for assistance if you spot any unusual activity on your account.
If you spot unusual or unfamiliar transactions on your bank or credit card statements, follow up immediately. That could indicate improper use. In general, banks, credit card companies, and many businesses have countermeasures to deal with fraud, along with customer support teams that can help you file a claim if needed.
Given number the accounts you might have, a credit monitoring service can help. McAfee’s credit monitoring service can help you keep an eye on changes to your credit score, report, and accounts with timely notifications and provide guidance so you can take action to tackle identity theft.
With some personal information in hand, bad actors may seek out more. They may follow up a high-profile attack with rounds of phishing attacks that direct you to bogus sites designed to steal your personal information—either by tricking you into providing it or by stealing it without your knowledge. So as it’s always wise to keep a skeptical eye open for unsolicited messages that ask you for information in some form or other, often in ways that urge or pressure you into acting.
If you are contacted by PayPal, make certain the communication is legitimate. Bad actors may pose as PayPal to steal personal information. Do not click on links sent in emails, texts, or messages. Instead, go straight to the PayPal website or contact them by phone directly.
An identity monitoring service can monitor everything from email addresses to IDs and phone numbers for signs of breaches so you can take action to secure your accounts before they’re used for identity theft. Personal information harvested from data breaches can end up on dark web marketplaces where it’s bought by other bad actors so they can launch their own attacks. McAfee’s monitors the dark web for your personal info and provides early alerts if your data is found on there, an average of 10 months ahead of similar services. We also provide guidance to help you act if your information is found.
When personal information gets released, there’s a chance that a hacker, scammer, or thief will put it to use. This may include committing fraud, where they draw funds from existing accounts, and theft, where they create new accounts in a victim’s name.
Another step that customers can take is to place a credit freeze on their credit reports with the major credit agencies. This will help prevent bad actors from opening new lines of credit or take out loans in a victim’s name by “freezing” their credit report so that potential creditors cannot pull it for reference.
McAfee+ plans give you guidance on how to place a full security freeze, stopping lenders and other companies from seeing your credit file. This halts the application process for loans, credit cards, utilities, new bank accounts, and more. A security freeze won’t affect your credit score.
A complete suite of online protection software can offer layers of extra security. In addition to more private and secure time online with a VPN, identity monitoring, and password management, it includes web browser protection that can block malicious and suspicious links that could lead you down the road to malware or a phishing scam—which antivirus protection can’t do alone.
Additionally, we offer $1 million in identity theft coverage and restoration support from a licensed recovery pro who can help you repair your identity and credit if you find yourself a victim.
Your Social Security or tax ID number is one of the most precious pieces of personal information you have. With them, an identity thief can open new accounts or lines of credit in your name, not to mention gain employment, claim insurance benefits, or even commit crimes in your name.
PayPal stated that victims may have had Social Security or tax ID number exposed. If you believe this occurred to you, file a report with the Federal Trade Commission (FTC), which handles such cases. From there, they will provide you with a set of next steps.
Not all data breaches make the news. Businesses and organizations, large and small, have all fallen victim to them, and with regularity. The measures you can take here are measures you can take even if you don’t believe you were caught up in the PayPal breach.
Data breaches typically make the news when it affects a large company and generally only after they discover and release word of it. This means you might not hear about a breach until weeks or even months after your stolen info has been in circulation on the dark web. The measures you can take here can mitigate the damage of such attacks, even if you don’t think you were caught up in a specific breach.
However, you have every reason to act now rather than wait for additional news. Staying on top of our credit and identity has always been important, but given all the devices, apps, and accounts we keep these days leaves us more exposed than ever, making protecting ourselves a must.

Holding the door for someone might open the way to a cyberattack. For anyone who works in a secure building or workplace, they might want to rethink that courtesy. The hackers and thieves behind piggybacking and tailgating attacks count on it.
Piggyback and tailgating attacks occur when an unauthorized person gains access to a restricted workplace, one that requires some form of ID to enter. While quite similar, these attacks have an important difference:
In both cases, these unauthorized entries can put businesses and organizations at risk. They give potential bad actors all kinds of access to sensitive information and devices.
Trade secrets get stolen this way, as does customer information. In yet more malicious cases, bad actors might gain entry with the intent of sabotaging technology or hijacking a network. And of course, bad actors might do harm to people or property.
Businesses and organizations that find themselves at risk include those that:
Different businesses and organizations have different forms of security in place. You might be among the many who use a smart badge or some form of biometric security to enter a building or certain areas within a building.
However, determined bad actors will look for ways around these measures. With piggyback and tailgating attacks, it’s far easier for them to follow someone into a workplace than it is to break into a workplace.
Bad actors will simply walk in when someone holds the door for them. It’s as simple as that. Additionally, they’ll try several different tricks by:
In all, piggybacking and tailgating attacks rely on social engineering—playing off people’s innate courtesy, willingness to help, or even discomfort with conflict. Essentially, the attacker manipulates human nature.
A good portion of prevention falls on the owner of the building, whether that’s a business, organization, or a landlord. It falls on them to install security hardpoints like badge scanners, keypad locks, biometric scanners, and so on to keep the property secure. Moreover, employers owe it to themselves and their employees to train them on security measures.
Yet you can take further steps to prevent a piggybacking or tailgating attack on your workplace. Some steps include:
Also consider the security of your devices or any other sensitive information you work with. If a bad actor slips into your workplace, you can take other steps to prevent theft or damage.
Some aspects of piggybacking and tailgating prevention seem like they go against our better nature. We want to be kind, helpful, and sometimes we’d simply rather avoid confrontation. Again, piggybackers and tailgaters count on that. Yet a door is only as secure as the person who uses it—or who opens it for someone else.

Have you ever been browsing online and clicked a link or search result that took you to a site that triggers a “your connection is not private” or “your connection is not secure” error code? If you’re not too interested in that particular result, you may simply move on to another result option. But if you’re tempted to visit the site anyway, you should be sure you understand what the warning means, what the risks are, and how to bypass the error if you need to.
A “your connection is not private” error means that your browser cannot determine with certainty that a website has safe encryption protocols in place to protect your device and data. You can bump into this error on any device connected to the internet — computer, smartphone, or tablet.
So, what exactly is going on when you see the “this connection is not private” error?
For starters, it’s important to know that seeing the error is just a warning, and it does not mean any of your private information is compromised. A “your connection is not private” error means the website you were trying to visit does not have an up-to-date SSL (secure sockets layer) security certificate.
Website owners must maintain the licensing regularly to ensure the site encryption capabilities are up to date. If the website’s SSL certificate is outdated, it means the site owners have not kept their encryption licensing current, but it doesn’t necessarily mean they are up to no good. Even major websites like LinkedIn have had momentary lapses that would throw the error. LinkedIn mistakenly let their subdomain SSL certificates lapse.
In late 2021, a significant provider of SSL certificates, Let’s Encrypt, went out of business. When their root domain officially lapsed, it created issues for many domain names and SSL certificates owned by legitimate companies. The privacy error created problems for unwitting businesses, as many of their website visitors were rightfully concerned about site security.
While it does not always mean a website is unsafe to browse, it should not be ignored. A secure internet connection is critical to protecting yourself online. Many nefarious websites are dangerous to visit, and this SSL certificate error will protect you from walking into them unaware.
SSL certification standards have helped make the web a safer place to transact. It helps ensure online activities like paying bills online, ordering products, connecting to online banking, or keeping your private email accounts safe and secure. Online security continues to improve with a new Transport Layer Security (TLS) standard, which promises to be the successor protocol to SSL.
So be careful whenever visiting sites that trigger the “connection is not private” error, as those sites can potentially make your personal data less secure and make your devices vulnerable to viruses and malware.
Note: The “your connection is not private” error is Google Chrome‘s phrasing. Microsoft Edge or Mozilla Firefox users will instead see a “your connection is not secure” error as the warning message.
If you feel confident that a website or page is safe, despite the warning from your web browser, there are a few things you can do to troubleshoot the error.
Remember, you are taking your chances anytime you ignore an error. As we mentioned, you could leave yourself vulnerable to hackers after your passwords, personal information, and other risks.
Your data and private information are valuable to hackers, so they will continue to find new ways to try and procure it. Here are some ways to protect yourself and your data when browsing online.
As we continue to do more critical business online, we must also do our best to address the risks of the internet’s many conveniences.
A comprehensive cybersecurity tool like McAfee+ Ultimate can help protect you from online scams, identity theft, and phishing attempts, and ensure you always have a secure connection. McAfee helps keep your sensitive information out of the hands of hackers and can help you keep your digital data footprints lighter with personal data cleanup.
With McAfee’s experts on your side, you can enjoy everything the web offers with the confidence of total protection.

Something looks a little…sketchy. Is that website safe or unsafe?
Nowadays, it can take a bit of work to tell.
And that’s by design. Increasingly, hackers and scammers go to great pains when they create their malicious websites. They take extra steps to make their sites look legit, when in fact they’re anything but. Certainly, plenty of other hackers and scammers slap together malicious sites that still look a bit roughshod, which makes them easier to spot.
So whether it’s a clever knockoff or a slapdash effort, unsafe websites of all kinds have several telltale signs you can spot. We’ll show you, and let’s start things off with what makes an unsafe website unsafe in the first place.
Unsafe websites typically harbor one of two primary forms of attack—yet sometimes both:
Malware: Hackers will use their sites to install malware on your device, often by tricking you into clicking or tapping on a download. They might tempt you with an offer, a prize, a show to stream—just about anything you might want to otherwise download. (Recently, we saw hackers installing malware on sites that offered to stream dubbed versions of the “Barbie” movie.)
Phishing: Another classic attack. Phishing involves scammers who try to hoodwink you into providing account or financial information. Common ruses include links in emails, texts, and DMs that appear to be urgent messages from streaming services, banks, social media, and other accounts. Of course, those messages are phony.
As a result, unsafe websites can lead to some not-so-good things.
On the malware side, attackers can install spyware and similar apps that siphon financial and personal information from your device while you’re using it. Other malware might steal files outright or maliciously delete them altogether. Ransomware remains a major concern today as well, where attackers hold devices and data hostage. And even if victims end up paying the ransom, they have no guarantee that the attacker will free their device or data.
Phishing attacks often lead to financial headaches, sometimes large ones at that. It depends on the information scammers get their hands on. In some cases, the damage might lead to identity fraud and a few illicit charges on a debit or credit card. If scammers gather enough information, they can take that a step further and commit identity theft. That can include opening new credit or loans in your name. It could also give a scammer the info they need to get driver’s licenses or employment in your name.
Above and beyond committing fraud or theft on their own, scammers might also sell stolen information to others on the dark web.
Again, all not-so-good. Yet quite preventable.
For some sites, it only takes one sign. For other sites, it takes a few signs—a series of red flags that warn you a site is unsafe. When you’re online, keep a sharp eye out for the following:
The site uses HTTP rather than HTTPS
The “s” stands for “secure.” Specifically, it means that the website uses SSL (Secure Sockets Layer) that creates an encrypted link between a web server and a web browser. SSL helps prevent others from intercepting and reading your sensitive information as it’s transmitted, which is particularly important when you shop or bank online. Likewise, you can also look for a little lock symbol in the address bar of your web browser. That’s one more way you can spot a site that uses SSL.
The site has a combination of typos and poor design
From spelling errors and grammatical mistakes, to stretched-out logos and cheap photography, some unsafe websites are designed poorly. Legitimate businesses pride themselves on error-free and professional-looking sites. If a website looks like it got cobbled together in a hurry or doesn’t seem to be well-designed, that’s usually a red flag. The site might be unsafe, created by attackers who don’t have strong attention to detail—or the creative capabilities to create a good-looking website in the first place.
The web address looks altered or off
Plenty of unsafe sites are imposter sites. They’ll try to pass themselves off as a legitimate company, like the streaming services, banks, and so forth that we mentioned earlier—all to get a hold of your account information. With all these imposter sites in play, look at the site’s address. Scammers will gin up web addresses that are close to but different from legitimate sites, so close that you might miss it. If you’re uncertain about the address, leave the page. Also, note that many companies have web pages that provide lists of the official addresses that they use. Amazon provides an example, and we do the same here at McAfee. Reviewing these lists can help you spot an imposter site.
The site says you have a security issue
A window or graphic pops up on your screen. The site you’re on says that it’s identified a security issue with your device. Or maybe it says that your system isn’t current. Either way, there’s a file the site wants you to download. “You can correct the issue with a click!” Don’t. It’s a classic trick. Instead of fixing your non-existent problem, the download will create one. Scammers use the security alert trick to install malware on the devices of unsuspecting victims.
The site floods you with pop-ups or links to click
A screen full of links insisting you click ranks among the top signs of an unsafe site. So much so, it’s often the subject of sitcom bits. Needless to say, the attackers behind these sites want you to click for one of several reasons. It might be to get you to download malware. It might be to generate ad revenue with clicks. Or it might be to get you to click a link that redirects you to another malicious site. In all, if you encounter a site like this, close your browser. And then run a system scan with your online protection software.
The site offers hard-to-get items at an outrageous discount
These unsafe sites sprout up around the holidays and gift-giving seasons. When stores run low on particularly popular or hot items, scammers will quickly launch sites that claim these items are in stock and ready to ship. Similarly, they might promote popular items at a deep discount. Of course, shopping at these sites will likely lead to one thing—a credit card charge and no item on your doorstep. Be wary when you see ads for stores in your social media feed, in search, and elsewhere. Stick with known, trusted retailers. (And for more on shopping safely online, give this article a quick read.)
The site promises access to hot shows, movies, and sporting events
These sites bear similarities to malicious online shopping sites. When popular movies hit the big screen or major sporting events come around, so do scam sites that promise to stream them for free or at a low cost. Avoid them. Trusted streamers will only carry shows and events that they have the rights to. If you find an offer to stream something that’s heavily discounted, free, or not available on known media outlets, it’s likely a scam. At the very least, it might serve up pirated content, which could carry malware threats along with it.
The site promotes prizes, coupons, or a quiz
Not every site that promotes some kind of giveaway or deal is a scam. Yet the ones that ask for personal or financial information likely are. Scammers prey on people’s love for saving money or even winning a buck or two. Enter the prize, coupon, and quiz sites. Malicious prize and coupon sites will often ask for credit or debit card information, often under the guise of a payout or a discount. Malicious quiz sites will likewise ask for all kinds of personal information, typically questions about the name of your pet, the first car you owned, or where you went to school. The questions share much in common with the security questions used by banks and credit card companies. Handing this information over could lead to a breached account. Give these sites a pass.
Comprehensive online protection software like ours includes web protection that can spot malicious sites for you. It has further features that can prevent downloading malware by accident, not to mention strong antivirus protection if a hacker makes their way through to you. In all, it gives you extra confidence that wherever your travels take you online, you’re protected from sketchy and unsafe sites.
However, another part of your best defense against unsafe websites is you. Knowing what the red flags are and the kinds of information hackers want to steal can help you avoid their attacks from the start.

How do hackers hack phones? Several ways. Just as there are several ways you can prevent it from happening to you.The thing is that our phones are like little treasure chests. They’re loaded with plenty of personal data, and we use them to shop, bank, and take care of other personal and financial matters—all of which are of high value to identity thieves. However, you can protect yourself and your phone by knowing what to look out for and by taking a few simple steps. Let’s break it down by first taking a look at some of the more common attacks.
Whether hackers sneak it onto your phone by physically accessing your phone or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, hacking software can create problems for you in a couple of ways:
Some possible signs of hacking software on your phone include:
In all, hacking software can eat up system resources, create conflicts with other apps, and use your data or internet connection to pass along your personal information into the hands of hackers—all of which can lead to some of the symptoms listed above.
These are a classic form of attack. In fact, hackers have leveled them at our computers for years now too. Phishing is where hackers impersonate a company or trusted individual to get access to your accounts or personal info or both. And these attacks take many forms, like emails, texts, instant messages, and so forth, some of which can look really legitimate. Common to them are links to bogus sites that attempt to trick you into handing over that info or that install malware to wreak havoc on your device or likewise steal information. Learning how to spot a phishing attack is one way to keep yourself from falling victim to one.
Professional hackers can use dedicated technologies that search for vulnerable mobile devices with an open Bluetooth connection. Hackers can pull off these attacks when they are within range of your phone, up to 30 feet away, usually in a populated area. When hackers make a Bluetooth connection to your phone, they can possibly access your data and info, yet that data and info must be downloaded while the phone is within range. As you probably gathered, this is a more sophisticated attack given the effort and technology involved.
In August of 2019, the CEO of Twitter had his SIM card hacked by SIM card swapping scam. SIM card swapping occurs when a hacker contacts your phone provider, pretends to be you, and then asks for a replacement SIM card. Once the provider sends the new SIM to the hacker, the old SIM card will be deactivated, and your phone number will be effectively stolen. This means the hacker has taken control of your phone calls, messages, and so forth. This method of hacking requires the seemingly not-so-easy task of impersonating someone else, yet clearly, it happened to the CEO of a major tech company. Protecting your personal info and identity online can help prevent hackers from impersonating you to pull off this and other crimes.
While there are several ways a hacker can get into your phone and steal personal and critical information, here are a few tips to keep that from happening:

In the fall of 2021, cryptocurrency value skyrocketed. Ethereum and Bitcoin had their highest values ever, causing a huge stir in interest in online currencies from experts, hobbyists and newbies alike … and in cybercriminals seeking huge paydays. Since then, cryptocurrency value has cooled, as has the public’s opinion about whether it’s worth the risk. Huge cryptohacking events dominate the headlines, leaving us to wonder: Is cryptocurrency losing its credibility?
In this article, you’ll learn about recent unfortunate crypto hacks and a few cryptocurrency security tips to help you avoid a similar misfortune.
A crypto wallet is the software or the physical device that stores the public and private keys to your cryptocurrency. A public key is the string of letters and numbers that people swap with each other in crypto transactions. It’s ok to share a public key with someone you trust. Your private key, however, must remain private — think of it like the password that secures your online bank account. Just like your actual wallet, if it falls into the wrong hands, you can lose a lot of money.
A malware called Mars Stealer infiltrated several crypto wallet browser extensions, including the popular MetaMask. The malware stole private keys and then erased its tracks to mask that it had ever gained entry to the wallet.1
One way to completely avoid a breach to your software crypto wallet is to opt for a hardware wallet. A hardware wallet is a physical device that can only be opened with a PIN. But there is some risk involved with a hardware wallet: if you drop it down the drain, all your crypto is gone. If you forget your wallet PIN, there is no customer service chatbot that can help you remember it. You are solely responsible for keeping track of it. For those who are confident in their hardware’s hiding spot and their personal organizational skills, they can benefit from its added security.
For anyone less sure of their ability to keep track of a hardware wallet, a software wallet is a fine alternative, though always been on alert of software wallet hacks. Keep an eye on crypto news and be ready to secure your software at a moment’s notice. Measures include un-downloading browser extensions, changing passwords, or transferring your crypto assets to another software wallet.
In the case of the Mars Stealer malware that affected MetaMask, being careful about visiting secure sites and only clicking on trustworthy links could’ve helped prevent it. Mars Stealer made its way onto people’s devices after they clicked on an infected link or visited a risky website. Stick to websites you know you can trust and consider springing for well-known streaming services and paying for software instead of torrenting from free sources.
Cryptocurrency enthusiasts often spread their crypto investments across various currency types and blockchain environments. Software known as a bridge can link numerous accounts and types, making it easier to send currency.
The cross-chain bridge Horizon experienced was on its Harmony blockchain, where a hacker stole about $100 million in Ethereum and tokens. The hacker stole two private keys, with which they could then validate this huge transaction into their own wallet. To hopefully prevent this from happening in the future, Horizon now requires more than just two validators.2
According to one report, in 2022, 69% of all cryptocurrency losses have occurred in bridge attacks.3 If you exchange cryptocurrencies with other users and have various accounts, it’s almost inevitable that you’ll use bridge software. To keep your assets safe, make sure to extensively research any bridge before trusting it. Take a look at their security protocols and how they’ve responded to past breaches, if applicable.
In the case of Horizon, the stolen private keys were encrypted with a passphrase and with a key management service, which follows best practices. Make sure that you always defend your private keys and all your cryptocurrency-related accounts with multi-factor authentication. Even though it may not 100% protect your assets, it’ll foil a less persistent cybercriminal.
Phishing attacks on bridge companies in conjunction with software hacks are also common. In this scenario, there’s unfortunately not much you can control. What you can control is how quickly and completely you respond to the cybercrime event. Remove the bridge software from your devices, transfer all your assets to a hardware wallet, and await further instructions from the bridge company on how to proceed.
Decentralized finance, or DeFi, is now one of the riskiest aspects of cryptocurrency. DeFi is a system without governing bodies. Some crypto traders like the anonymity and autonomy of being able to make transactions without a bank or institution tracking their assets. The drawback is that the code used in smart contracts isn’t bulletproof and has been at the center of several costly cybercrimes. Smart contracts are agreed upon by crypto buyers and sellers, and they contain code that programs crypto to perform certain financial transactions.
Three multi-million-dollar heists – Wormhole, Beanstalk Farms and Ronin bridge – occurred in quick succession, and smart contracts were at the center of each.4 In the case of Wormhole, a cybercriminal minted 120,000 in one currency and then traded them for Ethereum without putting up the necessary collateral. In the end, the hacker cashed out with $320 million. Beanstalk Farms lost $182 million when a hacker discovered a loophole in the stablecoin’s flash loan smart contract. Axie Infinity’s Ronin bridge was hit for $625 million when a hacker took control over and signed five of the nine validator nodes through a smart contract hole.4
To be safe, conduct all crypto transactions on well-known and trustworthy software, applications, bridges, and wallets that are backed by a governing body. What you lose in anonymity you gain in security by way of regulated protocols. Hackers are targeting smart contracts because they do not have to depend on large-scale phishing schemes to get the information they need. Instead, they can infiltrate the code themselves and steal assets from the smartest and most careful crypto users. Because there’s almost no way you can predict the next smart contract hack, the best path forward is to always remain on your toes and be ready to react should one occur.
Don’t let these costly hacks be what stops you from exploring crypto! Crypto is great as a side hustle if you’re committed to security and are strategic in your investments. Make sure you follow the best practices outlined and arm all your devices (mobile included!) with top-notch security, such as antivirus software, a VPN, and a password manager, all of which are included in McAfee +.
Privacy, excellent security habits, and an eagle eye can help you enjoy the most out of cryptocurrency and sidestep its costly pitfalls. Now, go forth confidently and prosper in the crypto realm!
