If you’re familiar with phishing or malware, you’ve likely heard of “malicious websites”. But, do you know how to spot one?
In this article, we’ll answer 4 key questions (and provide plenty of examples).
So, to start, let’s define what exactly a malicious website is.
A malicious website is any website that’s been designed to cause harm. In this article, we’ll focus on phishing websites and malware websites.
A phishing website – sometimes called a “spoof” or “lookalike” website – steals your data. Phishing websites look like legitimate websites. But, when visitors are prompted to enter login credentials, personal information, or credit card details, the data is directed to cybercriminals.
Looking for an example? Tessian researchers discovered 75 domains spoofing websites related to mail-in voting in August. For more information, read this article: How to Avoid Falling victim to Voting Scams in the 2020 Election. In this case, attackers were after personally identifiable information (PII) and credit card details.
Once a phishing website collects your data, it can be used in hacking operations and further phishing attacks, or sold on the dark web.
A malware website, on the other hand, installs malicious software on your device. While this could happen after the visitor downloads an application or file, it can also happen without the visitor even noticing.
Why deploy malware? Malicious software can serve many different purposes, including extracting data from a person’s device, taking control of the device, or using the device as an entry point into a network.
But phishing and malware sites aren’t the only problems.
Other websites, such as fake news and disinformation websites, might also be considered malicious websites. These sites aim to spread discord, affect election outcomes, and disrupt the activities of human rights groups.
It’s hard to say exactly how many malicious websites are out there. But one thing we do know is that malicious websites — particularly phishing websites — are popping up more and more frequently.
One source that can help us understand the prevalence of malicious websites is Google’s Safe Browsing reports.
According to Google’s stats, phishing websites are increasingly common, whereas malware sites are less likely to be favored by cybercriminals.
In September 2020, Google counted nearly 1,960,000 phishing websites. This is up from around 68,000 in September 2010 — an increase of nearly 2800%.
But malware sites have actually decreased in prevalence according to Google, with around 24.500 counted in September 2020, down from 78,500 in September 2010.
Venafi’s 2018 research supports the view that phishing sites are on the increase. In a study of domains associated with major retailers across five countries, Venafi found there were:
Let’s look at a real-life example of how criminals use malicious websites to dupe their targets into handing over data.
Research from BlackBerry, published in 2020, studied the activities of a cybercrime syndicate known as BAHAMUT. The group targets consumers, businesses, and government officials via phishing emails, fake mobile apps, and a “staggering” network of malicious websites.
Among many other activities, BAHAMUT set up convincing-looking malicious “news” websites that directly copied headlines from genuine sources. Links on these sites redirected to phishing websites that harvested Google, Yahoo, Microsoft, and Telegram users’ credentials.
BAHAMUT also set up websites designed to distribute a series of malicious mobile apps. Once downloaded, these malicious apps set up a “backdoor” on the target device, allowing the group to track the user’s activities and location, and access the user’s files.
Perhaps the most alarming aspect of BAHAMUT’s activities is the convincing nature of the group’s fake websites. Some of these sites were previously well-established, legitimate news sources, whose domains were re-registered and used as vehicles for cybercrime.
As we can see from the example of BAHAMUT, it’s not always easy to identify a malicious website. Some may display no obvious signs that they will steal your credentials or distribute malware.
But, there are some traits common to many malicious websites. For example:
These are outdated tactics, and most sophisticated malicious websites will not be so transparent.
There can also be technical indications that a website is fake. For example:
It can be very difficult to tell whether you are visiting a malicious website. The best tactic is to avoid arriving at a malicious website in the first place. But how?
When it comes to avoiding the harms associated with malicious websites — security and business leaders understand that prevention is better than cure.
And, while it is possible to stumble upon a malicious website while browsing the web, search engines, like Google take steps to remove malicious sites from their search results. They can’t catch them all, though.
But it’s important to note that it’s far more common to end up on a malicious website after receiving a phishing email. Phishing emails are extremely common — 88% of organizations experienced spear phishing (targeted phishing attacks) in 2019.
Phishing emails can include links to malicious websites. It’s easy to fall for this type of scam — a phishing email can appear to come from a trusted person, and might look like the sort of correspondence you receive from that person regularly.
That means identifying phishing emails may be more important than identifying malicious websites. If you’re looking for tips, we’ve put together this guide (including an infographic): What Does a Spear Phishing Email Look Like.
Note: Phishing can also take place via social media, phone, or SMS, but 96% of phishing attacks arrive via email. That’s why email is the threat vector security leaders are most concerned about. Email security solutions can help.
Tessian Defender detects and prevents advanced impersonation attacks including spear phishing. If employees don’t fall for the phishing email, they won’t land on the malicious website.
How? Tessian’s machine learning algorithms learn from historical email data to understand specific user relationships and the context behind each email. When an email lands in your inbox, Tessian Defender automatically analyzes millions of data points, including the email address, Display Name, subject line and body copy.
If anything seems “off”, it’ll be flagged.
