  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • CAPE detected the VirLock malware family;

The algorithms utilized in Win32/Virlock.AA (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy already exists, and possibly will exist. But that malware does not do all these horrible things instantly – it can take up to a few hours to cipher all of your files.

Usual ways of Win32/Virlock.AA distribution are typical for all other ransomware variants. Those are one-day landing sites where users are offered to download the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern strategy in malware spreading – you receive the e-mail that imitates some routine notifications about shippings or bank service conditions modifications. Within the email, there is an infected MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks quite simple, but still needs tons of recognition. Malware can hide in various places, and it is far better to stop it even before it goes into your PC than to depend on an anti-malware program. Common cybersecurity awareness is just an essential item in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a lot of money and time which you would certainly spend while trying to find a solution.
