How Secure is Video Conferencing?

For millions of people, it’s not a workday without it — video conferencing. And plenty of business gets done that way, which has made conferencing a target for hackers. That then begs the important question, how secure is video conferencing?

The answer is pretty secure if you’re using a reputable service. Yet you can take further steps to keep hackers and party crashers out of your meetings.

Why would someone want to crash your meeting? 

Hackers and party crashers are likely motivated by one of two things: financial gain or mischief.

Given that some meetings involve confidential or sensitive info, someone might have financial motivation to join in, spy on, or record the meeting. Recently, we saw the lengths at least one AI company went to when it spied on a competitor’s video conference call.[i]

And of course, some bad actors want to cause a disruption. As we saw in recent years, they’ll barge right into a meeting and create a ruckus with rude speech and other antics.

Falling somewhere in between, some hackers might try to intrude on a meeting and slip a malware-laden attachment into chat.[ii] For one, that can lead to a major disruption. And in a business context, financial disruption as well.

How do they pull it off? The typical avenues of attack apply. They might use stolen or hijacked accounts. The meeting was inadvertently set to “public,” allowing anyone with a link to join. Otherwise, they might compromise a victim’s device to piggyback their way in.

How to protect your video calls

Use a service with end-to-end encryption. 

Put simply, end-to-end encryption provides a solid defense against prying eyes. With it in place, this form of encryption makes it particularly difficult for hackers to tap into the call and the data shared within it. Secure video conferencing should use 256-bit AES GCM encryption for audio and video, and for sharing of screens, whiteboard apps, and the like. On a related note, read the service’s privacy policy and ensure that its privacy, security, and data measures fit your needs.

Make your meetings private and protect them with a password. 

Keep the uninvited out. First, setting your meeting to private (invitees only) will help keep things secure. Some apps also provide a notification to the meeting organizer when an invite gets forwarded. Use that feature if it’s available. Also, a password provides another hurdle for a hacker or bad actor to clear. Use a fresh one for each meeting.

Use the waiting room. 

Many services put attendees into a waiting room before they enter the meeting proper. Use this feature to control who comes in and out.

Block users from taking control of the screen. 

Welcome or unwelcome, you can keep guests from taking over the screen. Select the option to block everyone except the host (you) from screen sharing.

Turn on automatic updates on your conferencing app. 

By turning on automatic updates, you’ll get the latest security patches and enhancements for your video conferencing tool as soon as they become available.

Get wise to phishing scams. 

Some interlopers make it into meetings by impersonating others. Just as bad actors use phishing emails and texts to steal personal financial info, they’ll use them to steal company credentials as well. Our Phishing Scam Protection Guide can show you how to steer clear of these attacks.

Use online protection software. 

Comprehensive online protection software like ours can make for safer calls in several ways. For one, it protects you against malware attacks, such as if a bad actor tries to slip a sketchy download into your meeting. Further, it includes a password manager that creates and stores strong, unique passwords securely. This can help increase the security of your video conferencing account.

Also, get wise to AI deepfakes on video calls

This is a new one. AI deepfake technology continues to evolve, we find ourselves at the point where scammers can create AI imposters in real time.

We’ve seen them use this technology in romance scams, where scammers take on entirely new looks and voices on video calls. And we’ve seen at least one group of scammers bilk a company out of $25 million with deepfaked executives on a call.[iii]

Strange as it might sound, this kind of deepfake technology is possible today. And realizing that fact is the first step toward prevention. Next, that calls for extra scrutiny.

Any time-sensitive info or sums of money are involved, get confirmation of the request. Place a phone call to the person after receiving the request to ensure it’s indeed legitimate. Better yet, meet the individual in person if possible. In all, contact them outside the email, message, or call that initially made the request to ensure you’re not dealing with an imposter.

The safer video conference call

With the right provider and right steps in place, video calls can be quite secure. Use a solution that offers end-to-end encryption, keep your app updated for the latest security measures, and lock down the app’s security settings. Also, recognize that AI has changed the way we look at just about everything online — including people on the other side of the screen. As we’ve seen, AI imposters on calls now fall into the realm of possibility. A costly one at that.

How Do I Protect Myself When Using Wi-Fi?

How do you protect yourself when you use public Wi-Fi on your phone? For the 40% of people who say they use public Wi-Fi that way, it’s a good question to ask.

A recent study from Forbes found that plenty of people use public Wi-Fi — with 35% saying they use it at least four times a month.[i]

People have plenty of reasons for using public Wi-Fi on their phones. First off, they might want to save their cellular data usage. Maybe they want the speed it offers over a cell connection, like when they hop on a video call. In other cases, they might have a lousy cell signal indoors and want a better connection with Wi-Fi.

All are valid reasons for using public Wi-Fi. And all are reasons for knowing how to play it safe when you do.

The risks of public Wi-Fi

In an ideal world, public Wi-Fi is quite safe. The operator has it set up with the latest protection protocols, like the WP3 standard. The operator also has current, updated network equipment. You’re using it to connect to a site that uses “https” for security. And there’s no hackers or snoops in the network mix.

Of course, you can’t count on any of that every time you use public Wi-Fi.

The safer bet on public Wi-Fi…a VPN

So, what are your options if you want or need a public Wi-Fi connection?

The readiest answer is to use a VPN. As a “virtual private network,” it runs your data connection through a secure, encrypted tunnel exclusive to you. This way, it shields you and what you do from any prying eyes on public Wi-Fi.

The important bit here is to go with a trusted VPN provider. Ironically, many VPNs out there put you at risk. Some collect user info, particularly free VPNs. This gets bought and sold, and sometimes falls victim to data breaches — putting all kinds of personal info at risk.[ii] Moreover, some so-called VPNs install malware on phones instead. Others serve up ads in return for the free service.

With that, choosing a secure and trustworthy VPN provider is a must. A VPN like ours has both your security and privacy in mind. In a VPN, look for:

  • The same encryption strength that banks use.
  • One that doesn’t log or track what you do online, so your online activity remains private. ​
  • A VPN that’s independently audited for security and privacy.
  • One that covers plenty of devices and that offers unlimited data.
  • A connection that turns on automatically when using public Wi-Fi.

Not every VPN offers these features. Selecting one that does gives you the protection you want paired with the privacy you want.

More ways you can stay safer on public Wi-Fi

Turn off automatic connections.

Be choosy about the networks you connect to. Turning off automatic connections on your phone allows you to select the trusted networks you know best.

Keep your phone updated.

Set your operating system and apps to update automatically. Updates often include security fixes that shore up recently discovered shortcomings.

Watch out for extra taps to log in.

Hackers set up sketchy public Wi-Fi as bait. With it, they might siphon off personal info as you browse, bank, and shop. Others use it to install malware, like spyware that also steals personal info. Avoid any public Wi-Fi that asks you to download extra software or apps.

Prevent third parties from collecting your info.

Some internet service providers (ISPs) offer public Wi-Fi networks in various places. However, many ISPs track, gather, and sometimes share connection info. A VPN can put a stop to plenty of that, which makes this one more good reason to use one on public Wi-Fi.

Skip public Wi-Fi altogether.

If possible, use your data connection instead. Most mobile phone providers encrypt the traffic between cell towers and your device.

How to Protect Yourself from Vishing

“Vishing” occurs when criminals cold-call victims and attempt to persuade them to divulge personal information over the phone. These scammers are generally after credit card numbers and personal identifying information, which can then be used to commit financial theft. Vishing can occur both on your landline phone or via your cell phone.

The term is a combination of “voice,” and “phishing,” which is the use of spoofed emails to trick targets into clicking malicious links. Rather than email, vishing generally relies on automated phone calls that instruct targets to provide account numbers. Techniques scammers use to get your phone numbers include:

  • Data Breaches: Scammers often obtain phone numbers from data breaches where personal information is exposed and sold on the dark web.
  • Public Records: Phone numbers can be found in public records, such as court documents, voter registration lists, and property records, which are often accessible online.
  • Social Media: Many people share their contact information on social media profiles or posts, making it easy for scammers to collect phone numbers.
  • Online Surveys and Contests: Scammers create fake online surveys or contests that require participants to enter their phone numbers, which are then harvested for vishing.
  • Dumpster Diving: Physical documents thrown away without shredding, such as old phone bills or bank statements, can provide scammers with phone numbers. Once a visher has the list, he can program the numbers into his system for a more targeted attack.
  • Wardialing: A visher uses an automated system to target specific area codes with a phone call involving local or regional banks or credit unions. When someone answers the phone a generic or targeted recording begins, requesting that the listener enter a bank account, credit, or debit card number and PIN.

Once vishers have phone numbers, they employ various strategies to deceive their targets and obtain valuable personal information:

  • VoIP: Voice over Internet Protocol (VoIP) facilitates vishing by enabling vishers to easily spoof caller IDs, use automated dialing systems, and leverage AI-powered voice manipulation, all while operating from virtually anywhere with an internet connection. This combination of technologies makes it easier for scammers to appear legitimate and efficiently target numerous victims.
  • Caller ID Spoofing: Caller ID spoofing works by manipulating the caller ID information that appears on the recipient’s phone, making it seem as though the call is coming from a trusted or local source. Scammers use specialized software or VoIP services to alter the displayed number, which can mimic the number of a reputable institution, such as a bank or government agency.
  • Social Engineering: In live calls, vishers use social engineering techniques to build trust and manipulate the target into divulging personal information. They might pose as customer service representatives, tech support agents, or officials from financial institutions to convince you to hand over personal information.
  • Voice Manipulation Technology: Advanced AI-powered voice manipulation tools can mimic the voices of known individuals or create convincing synthetic voices, adding credibility to the call.
  • Urgency and Threats: Vishers often create a sense of urgency or fear, claiming immediate action is required to prevent serious consequences, such as account closure, legal action, or financial loss.

To protect yourself from vishing scams, you should:

  • Educate Yourself: Knowledge is the key to defending yourself from vishing. The more you understand it, the better off you’ll be, so read up on vishing incidents. As this crime becomes more sophisticated, you’ll want to stay up to date.
  • Use Call Blocking Tools: Utilize call blocking and caller ID spoofing detection tools offered by your phone service provider or third-party apps to filter out potential scam calls.
  • Be Skeptical of Caller ID: With phone spoofing, caller ID is no longer trustworthy. Since caller ID can be tampered with, don’t let it offer a false sense of security.
  • Do Not Share Personal Information: Never provide personal information, such as Social Security numbers, credit card details, or passwords, to unsolicited callers.
  • End the Call: If you receive a phone call from a person or a recording requesting personal information, hang up. If the call purports to be coming from a trusted organization, call that entity directly to confirm their request.
  • Report Suspicious Activity: Call your bank and report any fraud attempts immediately, noting what was said, what information was requested, and, if possible, the phone number or area code of the caller. Also report any suspicious calls to relevant authorities, such as the Federal Trade Commission (FTC), to help prevent others from falling victim to the same scams.

Staying vigilant and informed is your best defense against vishing scams. By verifying caller identities, being skeptical of unsolicited requests for personal information, and using call-blocking tools, you can significantly reduce your risk of falling victim to these deceptive practices. Additionally, investing in identity theft protection services can provide an extra layer of security. These services monitor your personal information for suspicious activity and offer assistance in recovering from identity theft, giving you peace of mind in an increasingly digital world. Remember, proactive measures and awareness are key to safeguarding your personal information against vishing threats.

How To Prevent Your Emails From Being Hacked

My mother recently turned 80, so of course a large celebration was in order. With 100 plus guests, entertainment, and catering to organise, the best way for me to keep everyone updated (and share tasks) was to use Google Docs. Gee, it worked well. My updates could immediately be seen by everyone, the family could access it from all the devices, and it was free to use! No wonder Google has a monopoly on drive and document sharing.

But here’s the thing – hackers know just how much both individuals and businesses have embraced Google products. So, it makes complete sense that they use reputable companies such as Google to devise phishing emails that are designed to extract our personal information. In fact, the Google Docs phishing scam was widely regarded as one of the most successful personal data extraction scams to date. They know that billions of people worldwide use Google so an invitation to click a link and view a document does not seem like an unreasonable email to receive. But it caused so much grief for so many people.

It’s All About Phishing

Emails designed to trick you into sharing your personal information are a scammer’s bread and butter. This is essentially what phishing is. It is by far the most successful tool they use to get their hands on your personal data and access your email.

‘But why do they want my email logins?’ – I hear you ask. Well, email accounts are what every scammer dreams of – they are a treasure trove of personally identifiable material that they can either steal or exploit. They could also use your email to launch a wide range of malicious activities from spamming and spoofing to spear phishing. Complicated terms, I know but in essence these are different types of phishing strategies. So, you can see why they are keen!!

But successful phishing emails usually share a few criteria which is important to know. Firstly, the email looks like it has been sent from a legitimate company e.g. Microsoft, Amex, or Google. Secondly, the email has a strong ‘call to action’ e.g. ‘your password has been changed, if this is not the case, please click here’. And thirdly, the email does not seem too out of place or random from the potential victim’s perspective.

What To Do To Prevent Your Email Being Hacked?

Despite the fact that scammers are savvy tricksters, there are steps you can take to maximise the chances your email remains locked away from their prying eyes. Here’s what I suggest:

  1. Don’t Fall Victim to a Phishing Scam

Never respond to an unexpected email or website that asks you for personal information or your login details no matter how professional it looks. If you have any doubts, always contact the company directly to verify.

  1. Protect Yourself!

Make sure you have super-duper internet security software that includes all the bells and whistles. Not only does internet security software McAfee+ include protection for daily browsing but it also has a password manager, a VPN, and a social privacy manager that will lock down your privacy settings on your social media accounts. A complete no-brainer!

  1. Say No to Public Wi-Fi and Public Computers

Avoid using public Wi-Fi to log into your email from public places. It takes very little effort for a hacker to position themselves between you and the connection point. So, it’s entirely possible for them to be in receipt of all your private information and logins which clearly you don’t want. If you really need to use it, invest in a Virtual Private Network (VPN) which will ensure everything you share via Wi-Fi will be encrypted. Your McAfee+ subscription includes a VPN.

Public computers should also be avoided even just to ‘check your email’. Not only is there a greater chance of spyware on untrusted computers but some of them sport key-logging programs which can both monitor and record the keys you strike on the keyboard – a great way of finding out your password!

  1. Passwords, Passwords, Passwords

Ensuring each of your online accounts has its own unique, strong, and complex password is one of the best ways of keeping hackers out of your life. I always suggest at least 10-12 characters with a combination of upper and lower case letters, symbols, and numbers. A crazy nonsensical sentence is a great option here but better still is a password manager that will remember and generate passwords that no human could! A password manager is also part of your McAfee+ online security pack.

What To Do If Your Email Is Hacked?

Even if you have taken all the necessary steps to protect your email from hackers, there is the chance that your email logins may be leaked in a data breach. A data breach happens when a company’s data is accessed by scammers and customers’ personal information is stolen. You may remember the Optus, Medibank and Latitude hacks of 2022/23?

If you have had your personal information stolen, please be assured that there are steps you can take to remedy this. The key is to act fast. Check out my recent blog post here for everything you need to know.

So, next time you’re organising a big gathering don’t hesitate to use Google Docs to plan or Microsoft Teams to host your planning meetings. While the thought of being hacked might make you want to withdraw, please don’t. Instead, cultivate a questioning mindset in both yourself and your kids, and always have a healthy amount of suspicion when going about your online life. You’ve got this!!

Till next time,
Stay safe!
Alex
