Win32/Filecoder.Hive.A detection is a virus detection you can spectate in your system. It usually appears after the provoking actions on your computer – opening the untrustworthy email messages, clicking the banner in the Internet or mounting the program from unreliable sources. From the moment it shows up, you have a short time to do something about it before it begins its harmful activity. And be sure – it is far better not to await these destructive effects.

What is Win32/Filecoder.Hive.A virus?

Win32/Filecoder.Hive.A is ransomware-type malware. It searches 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 documents inaccessible, this malware also does a ton of damage to your system. It modifies the networking settings in order to stop you from reading the elimination guides or downloading the antivirus. In rare cases, Win32/Filecoder.Hive.A can additionally prevent the launching of anti-malware programs.

Win32/Filecoder.Hive.A Summary

Summarizingly, Win32/Filecoder.Hive.A virus actions in the infected PC are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Guard pages use detected – possible anti-debugging.;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Anomalous binary characteristics;
  • Ciphering the files kept on the target’s disk drives — so the victim cannot open these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has been a headache for the last 4 years. It is difficult to picture a more harmful malware for both individual users and organizations. The algorithms utilized in Win32/Filecoder.Hive.A (typically, 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 virus does not do all these bad things instantly – it may take up to several hours to cipher all of your documents. Hence, seeing the Win32/Filecoder.Hive.A detection is a clear signal that you have to begin the clearing process.

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

Usual tactics of Win32/Filecoder.Hive.A distribution are standard for all other ransomware variants. Those are one-day landing websites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a quite new method in malware distribution – you get the email that mimics some routine notifications about deliveries or bank service conditions updates. Within the email, there is an infected MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks quite simple, but still requires a lot of focus. Malware can hide in different places, and it is far better to prevent it even before it goes into your PC than to depend on an anti-malware program. Simple cybersecurity knowledge is just an important item in the modern-day world, even if your interaction with a PC stays on YouTube videos. That may keep you a lot of time and money which you would certainly spend while looking for a fixing guide.
