Win32/Ramnit.A detection is a malware detection you can spectate in your system. It usually appears after the preliminary activities on your PC – opening the suspicious e-mail messages, clicking the advertisement in the Web or setting up the program from untrustworthy sources. From the second it appears, you have a short time to do something about it before it starts its malicious action. And be sure – it is much better not to await these harmful things.

What is Win32/Ramnit.A virus?

Win32/Ramnit.A is ransomware-type malware. It searches for the documents on your disk drives, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware also does a lot of harm to your system. It changes the networking settings in order to stop you from looking for the removal guides or downloading the antivirus. In rare cases, Win32/Ramnit.A can even stop the launching of anti-malware programs.

Win32/Ramnit.A Summary

In total, Win32/Ramnit.A virus activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • 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-malware programs
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a major problem for the last 4 years. It is hard to picture a more hazardous virus for both individuals and corporations. The algorithms used in Win32/Ramnit.A (usually, 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 actually exists, and possibly will exist. But that virus does not do all these terrible things immediately – it may take up to a few hours to cipher all of your documents. Thus, seeing the Win32/Ramnit.A detection is a clear signal that you should begin the clearing process.

Where did I get the Win32/Ramnit.A?

Standard ways of Win32/Ramnit.A 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 emails and hacktools. Bait e-mails are a relatively modern strategy in malware spreading – you receive the email that imitates some standard notifications about shipments or bank service conditions updates. Inside of the email, there is an infected MS Office file, or a 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 quite simple, but still demands a lot of focus. Malware can hide in various places, and it is better to stop it even before it gets into your PC than to rely on an anti-malware program. General cybersecurity awareness is just an essential item in the modern world, even if your interaction with a PC remains on YouTube videos. That can keep you a lot of money and time which you would certainly spend while trying to find a fix guide.
