What is Win64.Ransom.A virus?

Win64.Ransom.A is ransomware-type malware. It looks for the files 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 ton of damage to your system. It alters the networking settings in order to avoid you from looking for the removal guidelines or downloading the antivirus. Sometimes, Win64.Ransom.A can also prevent the setup of anti-malware programs.

Win64.Ransom.A Summary

In summary, Win64.Ransom.A malware activities in the infected PC are next:

  • Sample contains Overlay data;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Anomalous binary characteristics;
  • Ciphering the files located on the victim’s drives — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of security tools

Ransomware has been a major problem for the last 4 years. It is hard to imagine a more dangerous malware for both individuals and organizations. The algorithms utilized in Win64.Ransom.A (usually, 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. However, that malware 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 Win64.Ransom.A detection is a clear signal that you need to begin the elimination procedure.

Where did I get the Win64.Ransom.A?

Typical ways of Win64.Ransom.A injection are typical for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware distribution – you receive the e-mail that imitates some routine notifications about shippings or bank service conditions updates. Inside of the e-mail, there is a corrupted 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.

Avoiding it looks pretty simple, but still needs tons of awareness. Malware can hide in various spots, and it is far better to stop it even before it goes into your PC than to trust in an anti-malware program. Standard cybersecurity knowledge is just an essential item in the modern world, even if your interaction with a PC remains on YouTube videos. That can save you a lot of time and money which you would certainly spend while trying to find a solution.
