Ransomware has actually been a headache for the last 4 years. It is challenging to imagine a more hazardous virus for both individual users and businesses. The algorithms used in Ransom:Win32/StopCrypt.PBL!MTB (usually, 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 currently exists, and possibly will exist. However, that virus does not do all these horrible things instantly – it may require up to a few hours to cipher all of your files. Hence, seeing the Ransom:Win32/StopCrypt.PBL!MTB detection is a clear signal that you should start the clearing procedure.

Where did I get the Ransom:Win32/StopCrypt.PBL!MTB?

Typical tactics of Ransom:Win32/StopCrypt.PBL!MTB distribution are common for all other ransomware examples. Those are one-day landing web pages where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern tactic in malware distribution – you receive the e-mail that simulates some routine notifications about shippings or bank service conditions shifts. Inside of the email, there is a corrupted 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.

Avoiding it looks pretty easy, however, still requires a lot of recognition. Malware can hide in various spots, and it is better to stop it even before it invades your PC than to trust in an anti-malware program. Standard cybersecurity awareness is just an essential item in the modern world, even if your relationship with a computer stays on YouTube videos. That may save you a lot of money and time which you would certainly spend while looking for a solution.
