MSIL/Grenam-A

By Daniel Johnston

MSIL/Grenam-A detection is a virus detection you can spectate in your computer. It frequently shows up after the preliminary actions on your PC – opening the untrustworthy email messages, clicking the banner in the Web or installing the program from dubious resources. From the moment it appears, you have a short time to take action until it begins its harmful activity. And be sure – it is better not to wait for these harmful actions.

What is MSIL/Grenam-A virus?

MSIL/Grenam-A is ransomware-type malware. It looks for the documents on your disk drives, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware also does a lot of damage to your system. It modifies the networking settings in order to avoid you from checking out the elimination guides or downloading the antivirus. Sometimes, MSIL/Grenam-A can additionally prevent the setup of anti-malware programs.

MSIL/Grenam-A Summary

Summarizingly, MSIL/Grenam-A virus activities in the infected PC are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • At least one process apparently crashed during execution;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Possible date expiration check, exits too soon after checking local time;
  • Guard pages use detected – possible anti-debugging.;
  • Dynamic (imported) function loading detected;
  • Enumerates the modules from a process (may be used to locate base addresses in process injection);
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Uses Windows utilities for basic functionality;
  • Behavioural detection: Injection (inter-process);
  • Installs itself for autorun at Windows startup;
  • Attempts to modify Explorer settings to prevent hidden files from being displayed;
  • Encrypting the documents kept on the victim’s disk drives — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-virus programs

Ransomware has been a nightmare for the last 4 years. It is hard to picture a more harmful virus for both individual users and businesses. The algorithms utilized in MSIL/Grenam-A (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need 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 files. Therefore, seeing the MSIL/Grenam-A detection is a clear signal that you need to begin the clearing procedure.

Where did I get the MSIL/Grenam-A?

General tactics of MSIL/Grenam-A distribution are basic for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free app, so-called bait emails and hacktools. Bait e-mails are a quite modern method in malware spreading – you get the email that mimics some normal notifications about deliveries or bank service conditions shifts. Within 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.

Preventing it looks fairly uncomplicated, however, still demands a lot of recognition. Malware can hide in different spots, and it is better to prevent it even before it goes into your computer than to depend on an anti-malware program. Standard cybersecurity awareness is just an important item in the modern world, even if your interaction with a computer remains on YouTube videos. That may keep you a lot of money and time which you would certainly spend while searching for a fix guide.
