  • Zacinlo has its own updater, constantly helping to upgrade the malware without needing the interaction from the user
  • making screenshots of any page (can be bank information, logins, emails, messages and etc.) and sending them to the hackers
  • man-in-the-browser capabilities to decrypt SSL, letting any Javascript codes into the websites
  • ability to disable other adware, so there wouldn’t be any competition
  • uninstalling and deleting services based on the details from the command and control infrastructure
  • using Lua script to download additional components
  • shutting down the antivirus programs

The regular adware features involve redirecting, clickjacking, using Google AdSense to advertise, promotion placement on almost all pages (even HTTPS) and etc. As you can see not only your browsing experience becomes unpleasant because of the ads and slower speed, but also your privacy gets in great danger because hackers can see the screenshots of everything you do online.

How does Zacinlo adware install on computers

Throughout Zacinlo virus existence, this malware was associated with many programs that the hackers used to infect the gullible users.

Usually, this VPN product pops up on shady websites that are full of torrents, adult content, illegal music and etc. promoting free of charge services that are supposed to make you untraceable and less of a target for the malware.

Unfortunately, the software will do exactly the opposite and it only pretends to be a VPN service. Once the trojan-like software is executed it downloads some other elements that will later install the rootkit and adware features for Zacinlo.

In order not to get caught by the antivirus, the main downloader that got into your system as a VPN service uses Powershell command to freeze the real-time Windows Defender monitoring so that the malicious adware components and updater for the Zacinlo could get installed into computer unnoticed. After that, the protection will be enabled. This all happens in a matter of minutes and the compromised user simply thinks that this is how the program makes the VPN connection, while in reality, much more sinister processes are happening in the background.
