• SetUnhandledExceptionFilter detected (possible anti-debug);
• At least one process apparently crashed during execution;

• Creates RWX memory;
• Possible date expiration check, exits too soon after checking local time;
• Guard pages use detected – possible anti-debugging.;

Ransomware has been a horror story for the last 4 years. It is hard to picture a more dangerous virus for both individuals and businesses. The algorithms utilized in MSIL/Agent.EF (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist. But that malware does not do all these bad things immediately – it can take up to several hours to cipher all of your documents. Thus, seeing the MSIL/Agent.EF detection is a clear signal that you have to start the elimination process.

Where did I get the MSIL/Agent.EF?

Routine ways of MSIL/Agent.EF spreading are common for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a pretty modern strategy in malware distribution – you get the email that simulates some standard notifications about deliveries or bank service conditions changes. Inside of the email, there is an infected MS Office file, or a web link which opens the exploit landing site.

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

Avoiding it looks quite simple, however, still demands a lot of awareness. Malware can hide in different places, and it is better to stop it even before it goes into your system than to rely upon an anti-malware program. Basic cybersecurity knowledge is just an important 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 solution.
