MSIL/BadJoke.ABF detection is a virus detection you can spectate in your system. It often shows up after the provoking activities on your computer – opening the suspicious email, clicking the banner in the Internet or setting up the program from untrustworthy resources.

What is MSIL/BadJoke.ABF virus?

MSIL/BadJoke.ABF is ransomware-type malware. It searches for the documents on your disk, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware also does a ton of damage to your system. It alters the networking settings in order to stop you from checking out the removal guides or downloading the anti-malware program. In rare cases, MSIL/BadJoke.ABF can additionally stop the setup of anti-malware programs.

MSIL/BadJoke.ABF Summary

In summary, MSIL/BadJoke.ABF malware activities in the infected PC are next:

  • Dynamic (imported) function loading detected;
  • Possible date expiration check, exits too soon after checking local time;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;

Ransomware has actually been a headache for the last 4 years. It is hard to imagine a more hazardous malware for both individuals and organizations. The algorithms used in MSIL/BadJoke.ABF (generally, 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 already 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 files. Hence, seeing the MSIL/BadJoke.ABF detection is a clear signal that you need to start the removal process.

Where did I get the MSIL/BadJoke.ABF?

Typical methods of MSIL/BadJoke.ABF distribution are basic for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a relatively new tactic in malware distribution – you receive the email that imitates some routine notifications about shipments or bank service conditions updates. Within the email, there is a malicious MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks fairly simple, however, still demands a lot of attention. Malware can hide in different spots, and it is better to prevent it even before it goes into your computer than to rely on an anti-malware program. Essential cybersecurity knowledge is just an essential item in the modern-day world, even if your interaction with a PC remains on YouTube videos. That can keep you a great deal of money and time which you would spend while trying to find a solution.
