It generally appears after the preliminary activities on your computer – opening the dubious email messages, clicking the advertisement in the Web or mounting the program from untrustworthy sources.

What is Win32/Filecoder.Trigona.A virus?

Win32/Filecoder.Trigona.A is ransomware-type malware. It looks for the files on your computer, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, this virus also does a lot of damage to your system. It modifies the networking setups in order to stop you from reading the elimination manuals or downloading the anti-malware program. In rare cases, Win32/Filecoder.Trigona.A can additionally prevent the launching of anti-malware programs.

Win32/Filecoder.Trigona.A Summary

In total, Win32/Filecoder.Trigona.A ransomware actions in the infected computer are next:

  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • Creates an autorun.inf file;
  • Authenticode signature is invalid;
  • Yara detections observed in process dumps, payloads or dropped files;
  • Ciphering the documents located on the target’s disk drive — so the victim cannot open these files;
  • Blocking the launching of .exe files of anti-virus apps

Ransomware has actually been a horror story for the last 4 years. It is challenging to realize a more hazardous malware for both individual users and organizations. The algorithms utilized in Win32/Filecoder.Trigona.A (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. However, that virus does not do all these unpleasant things instantly – it can require up to several hours to cipher all of your documents. Therefore, seeing the Win32/Filecoder.Trigona.A detection is a clear signal that you should begin the removal procedure.

Where did I get the Win32/Filecoder.Trigona.A?

Common ways of Win32/Filecoder.Trigona.A distribution are basic for all other ransomware examples. Those are one-day landing websites where users are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a quite modern method in malware spreading – you receive the e-mail that mimics some regular notifications about shipments or bank service conditions changes. Within the email, there is an infected 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 fairly easy, but still demands a lot of focus. Malware can hide in different spots, and it is far better to prevent it even before it invades your system than to rely on an anti-malware program. Essential cybersecurity knowledge is just an essential item in the modern world, even if your relationship with a PC stays on YouTube videos. That can keep you a great deal of time and money which you would spend while looking for a fix guide.
