Trojan.BlackCat detection is a virus detection you can spectate in your system. It often appears after the preliminary procedures on your computer – opening the untrustworthy email, clicking the banner in the Web or setting up the program from dubious sources. From the instance it appears, you have a short time to take action until it starts its harmful action. And be sure – it is better not to wait for these malicious effects.

What is Trojan.BlackCat virus?

Trojan.BlackCat is ransomware-type malware. It looks for the documents on your computer, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware additionally does a lot of damage to your system. It alters the networking settings in order to stop you from reading the elimination manuals or downloading the anti-malware program. Sometimes, Trojan.BlackCat can also prevent the launching of anti-malware programs.

Trojan.BlackCat Summary

In total, Trojan.BlackCat malware actions in the infected PC are next:

  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • CAPE detected the BlackCat malware family;
  • Anomalous binary characteristics;
  • Encrypting the files located on the target’s disk — so the victim cannot check these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of security tools

Ransomware has been a nightmare for the last 4 years. It is challenging to realize a more dangerous malware for both individuals and organizations. The algorithms used in Trojan.BlackCat (usually, 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 already exists, and possibly will exist. But that malware does not do all these horrible things instantly – it may require up to a few hours to cipher all of your files. Therefore, seeing the Trojan.BlackCat detection is a clear signal that you should begin the elimination process.

Where did I get the Trojan.BlackCat?

Ordinary methods of Trojan.BlackCat distribution are usual for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a quite new tactic in malware distribution – you get the email that imitates some routine notifications about deliveries or bank service conditions shifts. Inside of the email, there is a corrupted MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks pretty simple, but still demands tons of recognition. Malware can hide in various places, and it is much better to prevent it even before it goes into your PC than to depend on an anti-malware program. Essential cybersecurity awareness is just an important item in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may save you a great deal of money and time which you would spend while seeking a solution.
