  • Ciphering the files kept on the target’s disk drives — so the victim cannot check these files;
  • Blocking the launching of .exe files of security tools

Ransomware has actually been a horror story for the last 4 years. It is hard to imagine a more hazardous malware for both individuals and businesses. The algorithms utilized in Virus.Win32.PolyRansom.a (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions.

Where did I get the Virus.Win32.PolyRansom.a?

Usual ways of Virus.Win32.PolyRansom.a distribution are typical for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a quite modern tactic in malware distribution – you receive the e-mail that simulates some standard notifications about deliveries or bank service conditions modifications. Inside of the email, there is an infected MS Office file, or a 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 easy, however, still needs a lot of recognition. Malware can hide in various spots, and it is much better to stop it even before it invades your system than to rely upon an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern-day world, even if your interaction with a computer stays on YouTube videos. That can save you a lot of time and money which you would spend while seeking a fix guide.
