Attackers are using fake Microsoft Store app listings to install malware

New malware attacks mimicking the Microsoft Store, Spotify’s website, and a PDF converter tool have recently been flagged online. ESET research recently shared images of the fake pages on Twitter. Bleeping Computer spoke with ESET’s head of threat detection labs to gain more insight on the attacks. The attacks work by using fake advertising to highlight pages containing malicious software disguised as genuine applications.

One example is the fake Microsoft Store app listing shown below. The listing claims to be for an online chess app. According to BleepingComputer, if you try to download it, you’ll instead get a zip file named ‘xChess_v.709.zip.” The file is actually a piece of information-stealing malware known as “Ficker” or “FickerStealer.” The same strategy is used with a fake Spotify page as well as a fake PDF converter page.

According to ESET research, the attacks are targeting countries in South America.

With the malware utilized in these attacks, threat actors can steal credentials saved within web browsers, messaging clients, and FTP clients. The malware can also steal over 15 cryptocurrency wallets, steal documents, and take screenshots of which apps are active on someone’s PC. This valuable information is then sent back to the attacker.

When browsing the web, you should always double-check the URL of any sites you download applications from. If your PC has been attacked, you should scan for malware and change your passwords. You may also want to pick up the best antivirus software to help secure your PC.
