Ransomware has been a horror story for the last 4 years. It is difficult to imagine a more dangerous malware for both individual users and organizations. The algorithms used in Win32/Filecoder.BlackBasta.B (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions.

Where did I get the Win32/Filecoder.BlackBasta.B?

Typical ways of Win32/Filecoder.BlackBasta.B distribution are standard for all other ransomware variants. Those are one-day landing websites where users are offered to download the free app, so-called bait emails and hacktools. Bait emails are a quite modern tactic in malware distribution – you get the e-mail that imitates some regular notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Preventing it looks fairly uncomplicated, however, still needs a lot of awareness. Malware can hide in various places, and it is much better to prevent it even before it gets into your PC than to rely on an anti-malware program. Standard cybersecurity knowledge is just an important item in the modern-day world, even if your interaction with a computer stays on YouTube videos. That may keep you a lot of time and money which you would spend while trying to find a fix guide.
