What is Win32/Diskcoder.Petya.G virus?

Win32/Diskcoder.Petya.G is ransomware-type malware. It searches for the documents on your disks, encrypts it, and then asks you to pay the ransom for getting the decryption key.

In rare cases, Win32/Diskcoder.Petya.G can additionally prevent the launching of anti-malware programs.

Win32/Diskcoder.Petya.G Summary

Summarizingly, Win32/Diskcoder.Petya.G malware activities in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • At least one process apparently crashed during execution;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • Authenticode signature is invalid;
  • Created a process from a suspicious location;
  • Anomalous binary characteristics;

  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a headache for the last 4 years. It is challenging to realize a more dangerous malware for both individuals and organizations. The algorithms used in Win32/Diskcoder.Petya.G (usually, 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 currently exists, and possibly will exist. But that malware does not do all these horrible things without delay – it may require up to a few hours to cipher all of your documents. Thus, seeing the Win32/Diskcoder.Petya.G detection is a clear signal that you have to begin the removal process.

Where did I get the Win32/Diskcoder.Petya.G?

Common methods of Win32/Diskcoder.Petya.G spreading are basic 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 e-mails and hacktools. Bait e-mails are a pretty new strategy in malware spreading – you get the email that simulates some normal notifications about shipments or bank service conditions modifications. Inside of the e-mail, there is a malicious 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 fairly uncomplicated, but still requires tons of focus. Malware can hide in various spots, and it is better to stop it even before it gets into your PC than to rely on an anti-malware program. Common cybersecurity knowledge is just an important item in the modern world, even if your relationship with a computer remains on YouTube videos. That may keep you a great deal of money and time which you would certainly spend while trying to find a fixing guide.
