Trojan:Win32/Ymacco.ABCB detection is a virus detection you can spectate in your computer. It usually appears after the preliminary actions on your PC – opening the dubious email, clicking the advertisement in the Internet or setting up the program from suspicious resources. From the moment it shows up, you have a short time to take action before it starts its destructive action. And be sure – it is much better not to wait for these malicious actions.

What is Trojan:Win32/Ymacco.ABCB virus?

Trojan:Win32/Ymacco.ABCB is ransomware-type malware. It looks for the documents on your disk, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus also does a lot of harm to your system. It changes the networking setups in order to avoid you from reading the removal tutorials or downloading the antivirus. In some cases, Trojan:Win32/Ymacco.ABCB can also prevent the setup of anti-malware programs.

Trojan:Win32/Ymacco.ABCB Summary

In summary, Trojan:Win32/Ymacco.ABCB malware actions in the infected computer are next:

  • Scheduled file move on reboot detected;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Reads data out of its own binary image;
  • Authenticode signature is invalid;
  • Deletes its original binary from disk;
  • Creates a copy of itself;
  • Ciphering the documents kept on the target’s disk drive — so the victim cannot use these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus programs

Ransomware has been a nightmare for the last 4 years. It is challenging to imagine a more harmful virus for both individual users and corporations. The algorithms used in Trojan:Win32/Ymacco.ABCB (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 already exists, and possibly will exist. However, that virus does not do all these horrible things immediately – it may take up to a few hours to cipher all of your files. Thus, seeing the Trojan:Win32/Ymacco.ABCB detection is a clear signal that you must start the removal procedure.

Where did I get the Trojan:Win32/Ymacco.ABCB?

Typical methods of Trojan:Win32/Ymacco.ABCB spreading are usual for all other ransomware variants. 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 emails are a pretty new method in malware spreading – you get the e-mail that mimics some standard notifications about shipments or bank service conditions updates. Within the email, there is an infected 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, but still needs a lot of recognition. Malware can hide in various places, and it is far better to prevent it even before it gets into your system than to depend on an anti-malware program. General cybersecurity knowledge is just an important thing in the modern world, even if your relationship with a computer remains on YouTube videos. That can keep you a great deal of time and money which you would spend while looking for a solution.
