  • Authenticode signature is invalid;
  • Encrypting the files kept on the target’s drives — so the victim cannot open these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a major problem for the last 4 years. It is hard to imagine a more hazardous virus for both individuals and organizations. The algorithms used in Downloader.MSIL (typically, 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. But that malware does not do all these terrible things instantly – it may require up to a few hours to cipher all of your documents. Thus, seeing the Downloader.MSIL detection is a clear signal that you have to begin the elimination process.

Where did I get the Downloader.MSIL?

General methods of Downloader.MSIL distribution are basic for all other ransomware variants. Those are one-day landing web pages where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a relatively new tactic in malware distribution – you receive the e-mail that imitates some normal notifications about deliveries or bank service conditions updates. Inside of the email, there is a corrupted MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks fairly uncomplicated, however, still needs tons of attention. Malware can hide in various places, and it is much better to stop it even before it invades your PC than to rely on an anti-malware program. Essential cybersecurity knowledge is just an essential thing in the modern world, even if your interaction with a PC stays on YouTube videos. That may save you a great deal of time and money which you would certainly spend while looking for a fix guide.
