Ransomware has been a nightmare for the last 4 years. It is challenging to realize a more harmful malware for both individual users and organizations. The algorithms utilized in Trojan:Win32/Raccrypt.GC!MTB (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy already exists, and possibly will exist. But that virus does not do all these horrible things instantly – it can require up to several hours to cipher all of your documents. Hence, seeing the Trojan:Win32/Raccrypt.GC!MTB detection is a clear signal that you have to start the removal process.

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

Typical tactics of Trojan:Win32/Raccrypt.GC!MTB distribution are common for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait emails and hacktools. Bait e-mails are a pretty new tactic in malware distribution – you get the email that imitates some standard notifications about deliveries or bank service conditions updates. Inside of the e-mail, there is a malicious MS Office file, or a 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 a lot of attention. Malware can hide in different spots, and it is much better to prevent it even before it gets into your system than to rely on an anti-malware program. Simple cybersecurity knowledge is just an important item in the modern world, even if your relationship with a PC remains on YouTube videos. That may keep you a great deal of time and money which you would spend while looking for a solution.
