Win32/GenKryptik.GCRJ detection is a malware detection you can spectate in your computer. It frequently shows up after the preliminary procedures on your computer – opening the dubious email messages, clicking the advertisement in the Web or mounting the program from dubious sources. From the moment it appears, you have a short time to take action before it starts its malicious activity. And be sure – it is far better not to await these harmful things.

What is Win32/GenKryptik.GCRJ virus?

Win32/GenKryptik.GCRJ is ransomware-type malware. It looks for the documents on your computer, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus also does a ton of harm to your system. It alters the networking setups in order to stop you from looking for the elimination tutorials or downloading the antivirus. Sometimes, Win32/GenKryptik.GCRJ can also prevent the launching of anti-malware programs.

Win32/GenKryptik.GCRJ Summary

In total, Win32/GenKryptik.GCRJ ransomware activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • CAPE extracted potentially suspicious content;
  • Unconventionial language used in binary resources: Tswana;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Checks the presence of disk drives in the registry, possibly for anti-virtualization;
  • Encrypting the files kept on the target’s drives — so the victim cannot open these files;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of security tools

Ransomware has actually been a headache for the last 4 years. It is difficult to imagine a more hazardous malware for both individual users and companies. The algorithms used in Win32/GenKryptik.GCRJ (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 already exists, and possibly will exist. But that malware does not do all these bad things instantly – it may take up to a few hours to cipher all of your documents. Thus, seeing the Win32/GenKryptik.GCRJ detection is a clear signal that you must begin the elimination process.

Where did I get the Win32/GenKryptik.GCRJ?

Usual methods of Win32/GenKryptik.GCRJ spreading are typical for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a quite modern tactic in malware spreading – you get the email that mimics some normal notifications about shippings or bank service conditions shifts. Within the email, there is a corrupted MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks fairly simple, but still needs tons of attention. Malware can hide in various places, and it is much better to stop it even before it goes into your PC than to depend on an anti-malware program. Standard cybersecurity awareness is just an essential thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may save you a great deal of time and money which you would certainly spend while looking for a solution.
