Summary

What is Trojan.Fruity.1?

  • A modular downloader trojan that can be used to distribute other malware.
  • Distributed through malicious websites and software installers that appear to be legitimate.
  • Once installed, Trojan.Fruity.1 begins a multi-stage infection process that can ultimately lead to the installation of the Remcos RAT spyware.

How does it work?

  • The trojan is implanted into legitimate programs, such as Python libraries, VLC mediaplayer, and VMWare virtualization software.
  • The trojan uses a variety of techniques to evade detection, including encryption, steganography, and process hollowing.
  • The trojan can be used to infect computers with other malware, such as ransomware, cryptominers, and backdoors.

How to prevent infection?

  • Only download software from trusted sources.

    When a visitor tries to download an app from a fake site, they are redirected to the MEGA file hosting service webpage, which offers them a zip file, containing a trojan installer package, for download.

    Another reason to use adblockers. Does ads that are part of search engine results can be dangerous.

      Yep. There’s a reason whenever i install an adblocker for a friend or family member they suddenly and mysteriously no longer “get viruses” anymore.

      Ad blocking is a security measure, because these ad networks have zero accountability for what you are shown. I will never in a million years allow ads onto my network intentionally. If i deem a service good enough that i think they deserve my money, i grab some merch or throw them a donation. It gives them more than tens of thousands of my ad impressions ever would.

      Yes, for home, if you are not installing ad-blockers for all your family members, you can set AdGuard DNS, etc., as DNS servers on your router to somewhat mitigate the ad/malware/scam problem for the entire location.
