What is Crab ransomware and how it works

Current encrypting viruses are not too complicated in their code, but even the easiest ransomware is extremely hazardous, and we’ll tell you why. They all apply the very strong encryption algorithms. Malicious programs' goal is not to actually steal the data. All it needs to do is to penetrate the machine, encode your data and delete the originals, leaving the encrypted versions instead of them. The information are unreadable if they are encrypted. You cannot use the files and cannot return them to norm. There are several methods to recover the files, and we've described each of them below.

The encoding programs, also called ransomware, are the viruses that infect users’ machines and spoil their info to earn money for its decryption. Most times, fraudsters get on victim's device through email spam or with zero-day Trojans. Hazardous mail is easy to recognize – you will get it suddenly, with some files attached to it. In case of zero-day vulnerabilities, it’s a bit harder – you won’t see what it will be until your files will corrupted which means that the best method is to properly update the system and other utilities that you use.

The thing is that modern encrypting programs exploit the famous ciphers, such as the RSA and the AES. They are the most complicated and cannot be broken.

We are certain that neither of these variants suits a user. The perfect way to beat ransomware is to abort its installation.

The smartest thing you can do now - to erase ransomware from your device and concentrate on the data restoration. We have said “attempt” as the probability to succeed with no decryption utility are faint.

How to decrypt Crab files

When you delete Crab from your system, and you double-checked it, you need to consider the decryption manners. Firstly, we should mention that the only 100% effective way is to load a backup. If you have the copies of the information and the ransomware is fully deleted – just erase the encrypted files and load the copies. If there were no backups – the chances to restore the data are slim to none. Shadow Volume Copies tool is what helps you to do it. We are saying about the inbuilt tool of Windows, and it duplicates every single file that was changed. You can access them with the help of custom restoration programs.

Naturally, the high-quality viruses might erase these copies, but if you're accessing the system from an entry without master privileges, Crab simply couldn’t perform that not having your permission. You might recollect that sometime prior to the showing of a scammer's message there was a different menu, suggesting to alter your device. If you have cancelled these changes – the copies are at your service, so you may use them and repair your files through such utilities as ShadowExplorer or Recuva. They may be found in the Net. You can download them from the sites of their creators, with tested guides.
