Ransomware has actually been a horror story for the last 4 years. It is hard to picture a more hazardous virus for both individual users and businesses. The algorithms used in MSIL/TrojanDownloader.Agent.GDT (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions.

Where did I get the MSIL/TrojanDownloader.Agent.GDT?

Typical tactics of MSIL/TrojanDownloader.Agent.GDT spreading are basic for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a relatively modern method in malware distribution – you get the e-mail that simulates some routine notifications about shipments or bank service conditions shifts. Inside of the email, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Preventing it looks fairly simple, however, still needs a lot of attention. Malware can hide in various spots, and it is much 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 important thing in the modern-day world, even if your relationship with a PC remains on YouTube videos. That may save you a lot of time and money which you would certainly spend while searching for a fix guide.
