The attacker utilized shared web hosting with all fake sites hosted on a single IP address in Russia.

Malicious URLs closely resemble legitimate websites, making it challenging for users to differentiate.

The attacker’s modus operandi involves luring users to click on fake sites where clicking on the Android button initiates the download of a malicious APK file, while clicking on the Windows button triggers the download of a BAT file, leading to a RAT payload download.

Skype:

The first fake site discovered was join-skype[.]info, designed to deceive users into downloading a fake Skype application.

The Windows button is directed to Skype8.exe and the Google Play button is pointed at Skype.apk.

Google Meet:

Another fake site, online-cloudmeeting[.]pro, mimicking Google Meet, was identified. The site provided links to download fake Skype applications for Android and Windows.

The Windows link led to a BAT file downloading DCRat, while the Android link led to a SpyNote RAT APK file.

Zoom:

Later, a fake Zoom site, us06webzoomus[.]pro, emerged with links to download SpyNote RAT for Android and DCRat for Windows.

The site closely resembled a legitimate Zoom meeting ID.

Open Directories:

The fake Google Meet and Zoom sites also contained additional malicious files like driver.exe and meet.exe (NjRAT), indicating potential future campaigns utilizing these files.

Businesses are at risk of impersonation attacks through online meeting applications, leading to the distribution of RATs that can compromise sensitive data.
