Typosquat campaign mimics 27 brands to push Windows, Android malware

A massive, malicious campaign is underway using over 200 typosquatting domains that impersonate twenty-seven brands to trick visitors into downloading various Windows and Android malware.

Typosquatting is an old method of tricking people into visiting a fake website by registering a domain name similar to that used by genuine brands.

The domains used in this campaign are very close to the authentic ones, featuring a single letter position swap or an additional “s,” making them easy for people to miss.

In terms of appearance, in most cases seen, the malicious websites are clones of the originals or at least convincing enough, so there’s not much to give away the fraud.

Victims typically end up on these sites by mistyping the website name they want to visit in the browser’s URL bar, which is not uncommon when typing on mobile.

However, users could also be led on these sites via phishing emails or SMS, direct messages, malicious social media and forum posts, and other ways.

A vast network of fake sites

Some of the malicious sites were discovered by cyber-intelligence firm Cyble, which published a report this week focusing on domains mimicking popular Android app stores like Google Play, APKCombo, and APKPure, as well as download portals for PayPal, VidMate, Snapchat, and TikTok.

Some of the domains used for this purpose are:

  • payce-google[.]com – impersonates Google Wallet
  • snanpckat-apk[.]com – impersonates Snapchat
  • vidmates-app[.]com – impersonates VidMate
  • paltpal-apk[.]com – impersonates PayPal
  • m-apkpures[.]com – impersonates APKPure
  • tlktok-apk[.]link – impersonates download portal for TikTok app

In all these cases, the malware delivered to users attempting to download the APKs is ERMAC, a banking trojan targeting banking accounts and cryptocurrency wallets from 467 apps.

Part of a much larger campaign

While Cyble’s report focused on the campaign’s Android malware, Found a much larger typosquatting campaign from the same operators, distributing Windows malware.

This campaign consists of over 90 websites created to impersonate over twenty-seven popular brands to distribute Windows malware, steal cryptocurrency recovery keys, and, as described above, push Android malware.

A notable example of one of these typosquat sites is for the very popular Notepad++ text editor. This fake site uses the domain “notepads-plus-plus[.]org”, which is only a character away from the authentic at “notepad-plus-plus.org”.

The files from this site install the Vidar Stealer information-stealing malware, which has had its size inflated to 700MB to evade analysis.

Another site discovered by the impersonates the Tor Project using the “tocproject.com” domain. In this case, the website drops the Agent Tesla keylogger and RAT.

By digging deeper into the long list of the domains, we’ve found several targeting popular software like:

  • thundersbird[.]org – Impersonates the popular Thunderbird open-source email suite, dropping Vidar Stealer
  • codevisualstudio[.]org – Impersonates Microsoft’s Visual Studio Code to drop Vidar
  • braves-browsers[.]org – Impersonates the Brave web browser to drop Vidar

The variety in the malware families delivered to victims may indicate that the campaign operators experiment with various strains to see what works best.

Another portion of these sites target cryptocurrency wallets and seed phrases, a very profitable activity for threat actors.

For example, Ffound “ethersmine[.]com”, which attempts to steal the visitor’s Ethereum wallet seed phrase.

Other sites in the campaign target cryptocurrency holders and digital asset investors impersonating popular crypto wallets, trading apps, and NFT sites.

Of course, the threat actors use multiple variants of each domain to cover as many mistypes as possible, so these domains are only a small sample of the entire network of domains used in the campaign.

Some browsers like Google Chrome and Microsoft Edge include typosquatting protection. However, in our tests, the browsers did not block any of the domains we tested.

To protect yourself from typosquatting domains, the best method to find a legitimate site is to search for a particular brand in a search engine.

However, you should avoid clicking on ads shown in search results, as there have been many cases where malicious ads are created to impersonate a real site.
