In total, Trojan:Win32/CryptRan.SA!MTB malware activities in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;

Those are one-day landing websites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively modern tactic in malware distribution – you receive the email that mimics some regular notifications about shippings or bank service conditions modifications. Within the e-mail, there is a malicious MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks pretty easy, but still needs a lot of focus. Malware can hide in various places, and it is better to prevent it even before it goes into your computer than to rely upon an anti-malware program. Common cybersecurity knowledge is just an essential item in the modern world, even if your interaction with a PC stays on YouTube videos. That can keep you a great deal of money and time which you would certainly spend while looking for a solution.
