Protect Your Company: Ransomware Prevention Made Easy

Every year hundreds of millions of malware attacks occur worldwide, and every year businesses deal with the impact of viruses, worms, keyloggers, and ransomware. Malware is a pernicious threat and the biggest driver for businesses to look for cybersecurity solutions.  Naturally, businesses want to find products that will stop malware in its tracks, and so they search for solutions to do that.

What is Antivirus and What Does It Really Protect?

Authored by Dennis Pang

What is antivirus? That’s a good question. What does it really protect? That’s an even better question. 

Over the years, I’ve come to recognize that different people define antivirus differently. Some see it as way to keep hackers from crashing their computers. Others see it as a comprehensive set of protections. Neither definition is entirely on the money. 

With this blog, I hope to give everyone a clear definition of what antivirus does well, along with what it doesn’t do at all. The fact is that antivirus is just one form of online protection. There are other forms of protection as well, and understanding antivirus’ role in your overall mix of online protection is an important part of staying safer online. 

What is antivirus? 

Antivirus software protects your devices against malware and viruses through a combination of prevention, detection, and removal.  

For years, people have installed antivirus software on their computers. Today, it can also protect your smartphones and tablets as well. In fact, we recommend installing it on those devices as well because they’re connected, just like a computer—and any device that connects to the internet is a potential target for malware and viruses.  

In short, if it’s connected, it must get protected. 

One important distinction about antivirus is its name, a name that first came into use decades ago when viruses first appeared on the scene. (More on that in a bit.) However, antivirus protects you from more than viruses. It protects against malware too. 

Malware is an umbrella term that covers all types of malicious software regardless of its design, intent, or how its delivered. Viruses are a subset of malicious software that infects devices and then replicates itself so that it can infect yet more devices. 

So while we popularly refer to protection software as antivirus, it protects against far more than just viruses. It protects against malware overall. 

Now here’s where some confusion may come in. Some antivirus apps are standalone. They offer malware protection and that’s it. Other antivirus apps are part of comprehensive online protection software, which can include several additional far-reaching features that can protect your privacy and your identity.  

The reason why antivirus gets paired up with other apps for your privacy and identity is because antivirus alone doesn’t offer these kinds of protections. Yet when paired with things like a password manager, credit monitoring, identity theft coverage, and a VPN, to name a few, you can protect your devices—along with your privacy and identity. All the things you need to stay safer online. 

In short, antivirus doesn’t cut it alone. 

With that, let’s take a closer look at what malware and viruses really are—how they evolved, and what they look like today, along with how antivirus protects you against them. 

What was the first computer virus? 

Viruses have a long history. And depending on how you define what a virus is, the first one arguably took root in 1971—more than 50 years ago.  

It was known as Creeper, and rather than being malicious in nature, it was designed to show how a self-replicating program could identify other connected devices on a network, transfer itself to them, and find yet more devices to repeat the process. Later, the same programmer who created a follow-on version of Creeper developed Reaper, a program that could remove the Creeper program. In a way, Reaper could be considered the first piece of antivirus software. 

From there, it wasn’t until the 1980’s that malware started affecting the broader population, a time when computers became more commonplace in businesses and people’s homes.  

At first, malware typically spread by infected floppy disks, much like the “Brain” virus in 1986. While recognized today as the first large-scale computer virus, its authors say they never intended it to work that way. Rather they say they created Brain as an anti-piracy measure to protect their proprietary software from theft. However, Brain got loose. It went beyond their software and affected computers worldwide. Although not malicious or destructive in nature, Brain most certainly put the industry, businesses, and consumers on notice.  

Computer viruses became a thing. 

Another piece of malware that got passed along via floppy disks was the “PC Cyborg” attack that targeted the medical research community in and around 1989. There the malware would lie in wait until the user rebooted their computer for the 90th time. And on that 90th boot, the user was presented with a digital ransom note like the one here: 

Along with that note, PC Cyborg encrypted the computer’s files, which would only get unencrypted if the victim paid a fee—making PC Cyborg the first widely recognized form of ransomware. 

Shortly thereafter, the internet started connecting computers, which opened millions of doors for hackers as people went online. Among the most noteworthy was 1999’s “Melissa” virus, which spread by way of infected email attachments and overloaded hundreds of corporate and governmental email servers worldwide.  

It was quickly followed in 2000 by what’s considered the among the most damaging malware to date—ILOVEYOU, which also spread by way of an attachment, this one posing as a love letter. Specifically, it was a self-replicating worm that installed itself on the victim’s computer where it destroyed some information and stole other information, then spread to other computers. One estimate puts the global cost of ILOVEYOU at $10 billion and further speculated that it infected 10% of the world’s internet-connected computers at the time. 

Today’s malware and viruses—even more malicious today 

With the advent of the internet, malware quickly established itself as a sad fact of connected life. Today, McAfee registers an average of 1.1 million new malicious programs and potentially unwanted apps (PUA) each day, which contributes to the millions and millions of malicious programs already in existence.   

Apart from the sheer volume of malware out there today, another thing that distinguishes today’s malware from early malware attacks—they’re created largely for profit. 

We can think of it this way:  

• Consider all the banking, shopping, and personal business you conduct on your computer, tablet, and smartphone. If a bad actor can hack into your device with malware, it may give them access to your online banking accounts, credit cards, and other financial information. 
• Further, think of the important files you have stored on your devices. That may include tax returns, financial documentation, or payment information, which hackers can steal using malware—and then use it to commit identity theft or sell it to other bad actors on the dark web. 
• Finally, consider the digital valuables you have stored on your devices, like photos, personal letters, music, and even games. If a hacker locks them up with a ransomware attack, you might find yourself wondering if you should take the risk of paying the ransom, even though payment is no assurance that you’ll get them back. 

Today’s malware is far more than an annoyance or headache. It can lead to follow-on attacks that target your finances, your identity, your privacy, or a mix of all three. 

How does antivirus keep you safe?  

So with a million or so new threats coming online each day, and millions more out there already, how does antivirus protect you from malware? It blocks, detects, and removes malware. And it does so in a couple of ways: 

1. It protects you from existing threats based on an extensive list of known threats, which is updated regularly (a good reason to set your software to update automatically rather than manually). 
2. It protects you from entirely new threats with technologies that can accurately detect those threats. Not to get overly technical about it, this entails a blend of deep learning algorithms and artificial intelligence (AI) that spots new threats identifying sketchy behavior, such as abnormal demands and instructions. In short, the best antivirus today is smart. 

However, as mentioned earlier, antivirus provides only one aspect of online protection today. While it protects your devices and the data that’s on them, your privacy and identity can come under attack as well. So while antivirus alone can protect you from malware, it can’t prevent other forms of online crime like identity theft, phishing attacks designed to steal personal information, or attacks on your accounts, to name a few of the many other types of threats out there. 

Yet comprehensive online protection can. 

Antivirus, an essential part of your overall security mix 

Comprehensive online protection software like ours offers antivirus, along with specific services and features that protect your privacy and identity online as well. It gives you dozens of other features like identity theft coverage & restoration, personal data cleanup, security freezes, and an online protection score that shows you just how safe you are, along with suggestions that can make you safer still.  

So while protecting your devices with antivirus is a great start, it’s only one part of staying safer online. Including privacy and identity protection rounds out your protection overall.

Tax Scams – Everything you need to know to keep your money and data safe

Tax season has always been a pretty nerve-wracking time for hard-working Americans. But over the years, technology advances have arrived to gradually make the process a bit easier. The bad news is that they can also introduce new cyber risks and even more stress.

There are two things that cybercriminals are always on the hunt for: people’s identity data from their accounts, and their money. And during the tax-filing season both can be unwittingly exposed. Over the years, cybercriminals have adapted multiple tools and techniques to part taxpayers with their personal information and funds.

Let’s take look at some of the main threats out there and what you can do to stay safe.

What do they want?

Cybercrime is a highly efficient money-making business. Some reports suggest this underground economy generates as much as $1.5 trillion each year. (See Into the Web of Profit, April 2018, McGuire, Bromium.) And tax-related scams are an increasingly popular way for the bad guys to drive-up profits. The Internal Revenue Service (IRS) claims that “thousands of people have lost millions of dollars and their personal information” to such attacks.

The bottom line is that they’re after one of two things: to trick you into wiring funds to them, and/or to get hold of your personally identifiable information (PII), including bank account and Social Security Numbers (SSNs). This personal data can subsequently be used to defraud you or the IRS, or may be deployed in follow-on identity fraud schemes to capture illicit funds from you.

There are various ways cyber-criminals can achieve these goals. The most common is by using social engineering tactics to trick taxpayers into sending money or personal information. But they might also use malware, either delivered to you personally or targeted at your tax preparer. This means you not only have to look after your own cybersecurity but also demand that the third-party businesses you work with store and transmit your sensitive information securely.

Look out for these scams

Here’s a round-up of the most popular tactics used by tax scammers today:

Impersonation: The fraudster gets in touch pretending to be an IRS representative. This could be via email, phone, social media or even SMS. They usually claim you owe the IRS money in unpaid taxes or fines and demand a wire transfer, or funds from a prepaid debit card. Sometimes they may ask for personal and financial details—for example, by claiming you’re entitled to a large tax refund and they just need you to supply your bank account info.

These interactions are usually pushy. The scammer knows the best way of making you pay up is by creating a sense of urgency and, sometimes, shaming the individual into believing they’ve been withholding tax payments. Phishing emails may look highly convincing, right down to the logo and sender domain, while phone callers will use fake names and badge numbers. Sometimes the scammers use personal data they may have stolen previously or bought on the Dark Web to make their communications seem more convincing.

In some impersonation scams, the fraudsters may even pretend to work for charities and ask for personal details to help disaster victims with tax refund claims.

Spoofing, phishing, and malware: In some cases, a text, email or social media message spoofed to appear as if sent from the IRS or your tax preparer actually contains malware. The scammers use the same tactics as above but trick the recipient into clicking on a malicious link or opening an attachment laden with malware. The covert download that follows could result in: theft of your personal information; your computer being completely hijacked by hackers via remote control software; or a ransomware download that locks your computer until you pay a fee.

Fake tax returns: Another trick the scammers employ is to use stolen SSNs and other personal information to file tax returns on your behalf. They can then try to claim a large payment in tax refunds from the IRS. The PII they use to file in your name may have been taken from a third-party source without your knowledge, and the first you might hear of it is when you go to file a legitimate tax return. It can take months to resolve the problem.

Attacks targeting tax preparers: Over half of Americans use third-party tax preparation companies to help them with their returns. However, this offers another opportunity for scammers to get hold of your sensitive information. In one recently discovered campaign, malware deployed on tax preparers’ websites was designed to download to the visitor’s computer as soon as they loaded the page. The IRS warns that businesses large and small are potentially at risk, as scammers are keen to get hold of tax information which enables them to file highly convincing fake returns in your name.

What to do

The good news is that by taking a few simple steps you can insulate yourself from the worst of these scams. Remember: the IRS does not contact taxpayers by email, text messages or social media to request personal/financial information— so if you receive communications that do, they are definitely a scam. It’s also important to remember that scams happen all year round, not just in the run-up to the tax filing deadline. That means, unfortunately, that you need to be on your guard all the time.

Here are a few other recommendations:

Install anti-malware from a reputable provider to block phishing emails and websites and prevent malware downloads. Be wary of any unsolicited messages purporting to come from your tax preparer or the IRS. Always contact them directly to check whether it’s a genuine communication or not. Don’t click on any links in unsolicited emails, or download attachments. Obtain an Identity Protection PIN from the IRS before filing your taxes. This will prevent fake returns being filed in your name. Alert phishing@irs.gov about any unsolicited emails from IRS scammers. Protect your log-ins with tax preparation companies. Switch on multi-factor authentication (MFA) if available, and/or use a password manager to make your logins hard to guess or crack.

It also pays to demand that your tax preparer take their own precautions to keep your data secure. They should not be sending sensitive data or documents unencrypted in emails and must take steps on their own to combat phishing emails that target employees, since these can cascade to you during your tax preparation process. Whether hosted in the cloud or running on-premises, the servers that hold your data should also have adequate protection—and you have a right (and a duty to yourself) to ask ahead of time what they’re doing to protect it.

According to the IRS tax preparers should put the following internal controls in place:

Install anti-malware on all web and storage servers and keep their software automatically updated. Encourage the use of unique, strong passwords via a password manager for each account, and deploy multi-factor authentication technology for clients. Encrypt all sensitive files and emails exchanged with strong password protections. Back-up sensitive data regularly to a secure off-site source. Wipe clean/destroy any old hard drives and printers containing sensitive data. Limit access to taxpayer data to staff who need to know.
