Ransomware has been a horror story for the last 4 years. It is hard to picture a more damaging virus for both individual users and companies. The algorithms used in Trojan:Win32/Raccrypt.GZ!MTB (generally, 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 actually exists, and possibly will exist. However, that virus does not do all these bad things immediately – it may require up to several hours to cipher all of your files. Thus, seeing the Trojan:Win32/Raccrypt.GZ!MTB detection is a clear signal that you must start the clearing process.

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

Common ways of Trojan:Win32/Raccrypt.GZ!MTB injection are typical for all other ransomware variants. Those are one-day landing sites where users are offered to download the free software, so-called bait emails and hacktools. Bait emails are a quite modern strategy in malware distribution – you get the email that simulates some normal notifications about shipments or bank service conditions updates. Inside of the e-mail, there is a malicious MS Office file, or a web 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 pretty simple, but still needs tons of attention. Malware can hide in different places, and it is far better to prevent it even before it goes into your computer than to rely on an anti-malware program. Common cybersecurity awareness is just an important thing in the modern-day world, even if your relationship with a PC remains on YouTube videos. That can keep you a great deal of time and money which you would certainly spend while seeking a solution.
