What is Trojan:Win32/Stealc.CA!MTB virus?

Trojan:Win32/Stealc.CA!MTB is ransomware-type malware. It looks for the documents on your computer, encrypts it, and then asks you to pay the ransom for getting the decryption key.

Sometimes, Trojan:Win32/Stealc.CA!MTB can additionally prevent the launching of anti-malware programs.

Ransomware has actually been a headache for the last 4 years. It is challenging to realize a more hazardous malware for both individual users and companies. The algorithms utilized in Trojan:Win32/Stealc.CA!MTB (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy actually exists, and possibly will exist. However, that virus does not do all these terrible things immediately – it may require up to a few hours to cipher all of your documents. Hence, seeing the Trojan:Win32/Stealc.CA!MTB detection is a clear signal that you have to start the elimination process.

Where did I get the Trojan:Win32/Stealc.CA!MTB?

Usual tactics of Trojan:Win32/Stealc.CA!MTB injection are common for all other ransomware variants. Those are one-day landing websites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a pretty new method in malware distribution – you receive the email that imitates some routine notifications about shippings or bank service conditions updates. 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.

Preventing it looks pretty simple, however, still demands a lot of awareness. Malware can hide in different places, and it is much better to prevent it even before it gets into your computer than to trust in an anti-malware program. Basic cybersecurity awareness is just an essential thing in the modern-day world, even if your interaction with a computer remains on YouTube videos. That can keep you a lot of time and money which you would spend while looking for a fix guide.
