Mal/GandCrab-C detection is a virus detection you can spectate in your computer. It frequently shows up after the provoking actions on your PC – opening the suspicious email, clicking the advertisement in the Web or installing the program from suspicious resources. From the second it shows up, you have a short time to act until it begins its harmful activity. And be sure – it is much better not to await these malicious actions.

What is Mal/GandCrab-C virus?

Mal/GandCrab-C is ransomware-type malware. It looks for the documents on your disk, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents inaccessible, this malware also does a ton of harm to your system. It modifies the networking setups in order to stop you from reading the elimination tutorials or downloading the anti-malware program. Sometimes, Mal/GandCrab-C can even block the setup of anti-malware programs.

Mal/GandCrab-C Summary

In total, Mal/GandCrab-C ransomware activities in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Uses Windows utilities for basic functionality;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • The executable is compressed using UPX;
  • Authenticode signature is invalid;
  • CAPE detected the Gandcrab malware family;
  • Checks the CPU name from registry, possibly for anti-virtualization;
  • Yara detections observed in process dumps, payloads or dropped files;
  • Encrypting the files located on the target’s drive — so the victim cannot use these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of security tools

Ransomware has actually been a major problem for the last 4 years. It is hard to realize a more damaging malware for both individual users and businesses. The algorithms utilized in Mal/GandCrab-C (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy actually exists, and possibly will exist. But that malware does not do all these unpleasant things immediately – it can take up to a few hours to cipher all of your files. Therefore, seeing the Mal/GandCrab-C detection is a clear signal that you should start the clearing process.

Where did I get the Mal/GandCrab-C?

Usual methods of Mal/GandCrab-C distribution are basic for all other ransomware examples. Those are one-day landing sites where victims are offered to download and install the free software, so-called bait emails and hacktools. Bait emails are a pretty modern strategy in malware distribution – you get the email that imitates some normal notifications about shipments or bank service conditions modifications. Within the e-mail, there is a corrupted 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.

Preventing it looks fairly simple, however, still demands tons of attention. Malware can hide in various places, and it is far better to prevent it even before it invades your system than to trust in an anti-malware program. General cybersecurity awareness is just an essential thing in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may save you a great deal of money and time which you would certainly spend while trying to find a fix guide.
