Ransomware has been a nightmare for the last 4 years. It is hard to imagine a more dangerous virus for both individuals and corporations. The algorithms utilized in Trojan:MSIL/AgentTesla (usually, 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. However, that malware does not do all these horrible things immediately – it can require up to several hours to cipher all of your documents. Therefore, seeing the Trojan:MSIL/AgentTesla detection is a clear signal that you have to start the clearing procedure.

Where did I get the Trojan:MSIL/AgentTesla?

Usual methods of Trojan:MSIL/AgentTesla distribution are common for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a quite new method in malware spreading – you get the e-mail that simulates some regular notifications about shippings or bank service conditions updates. Inside of the e-mail, there is a corrupted MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly easy, however, still demands tons of awareness. Malware can hide in various places, and it is far better to prevent it even before it goes into your PC than to depend on an anti-malware program. Simple cybersecurity awareness is just an important thing in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may keep you a great deal of time and money which you would certainly spend while trying to find a fix guide.
