  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Anomalous .NET characteristics;
  • Binary compilation timestomping detected;

Ransomware has actually been a nightmare for the last 4 years. It is challenging to picture a more harmful malware for both individual users and organizations. The algorithms used in MSIL/Filecoder.AQG (generally, 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 currently exists, and possibly will exist. But that malware does not do all these terrible things immediately – it may require up to several hours to cipher all of your files. Hence, seeing the MSIL/Filecoder.AQG detection is a clear signal that you have to start the elimination procedure.

Where did I get the MSIL/Filecoder.AQG?

Common ways of MSIL/Filecoder.AQG distribution are common for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a quite new tactic in malware distribution – you get the email that imitates some standard notifications about deliveries or bank service conditions modifications. Within the e-mail, there is an infected 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.

Preventing it looks fairly simple, but still demands tons of attention. Malware can hide in different spots, and it is much better to prevent it even before it invades your PC than to rely on an anti-malware program. Standard cybersecurity awareness is just an essential thing in the modern world, even if your relationship with a PC remains on YouTube videos. That may keep you a lot of money and time which you would spend while seeking a fixing guide.
