Ransomware has been a horror story for the last 4 years. It is hard to realize a more hazardous malware for both individual users and organizations. The algorithms used in Trojan:Win32/Raccrypt.RA!MTB (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these bad things immediately – it can take up to a few hours to cipher all of your documents. Therefore, seeing the Trojan:Win32/Raccrypt.RA!MTB detection is a clear signal that you must begin the removal process.

Where did I get the Trojan:Win32/Raccrypt.RA!MTB?

Common tactics of Trojan:Win32/Raccrypt.RA!MTB spreading are typical for all other ransomware variants. Those are one-day landing web pages where users are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a relatively new tactic in malware spreading – you receive the email that simulates some normal notifications about shippings or bank service conditions changes. Within the e-mail, there is an infected 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 quite uncomplicated, however, still demands tons of recognition. Malware can hide in different places, and it is better to prevent it even before it gets into your computer than to trust in an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern-day world, even if your interaction with a PC stays on YouTube videos. That may keep you a lot of time and money which you would spend while seeking a fix guide.
