What is GANDCRAB 4 Ransomware

Gandcrab 4 is the newest version of most dangerous PC virus GANDCRAB RANSOMWARE. Unfortunately, the virus codes users files and adds new .KRAB extension (without any permission) by the most advanced algorithms of encryption AES-256 and RSA-2048(CBC), Salsa20, which made infected files undecryptable without special code. Users just lose their important files. Gandcrab 4 can encrypt pictures and photos with different extensions, all videos, databases, document file, for example, PDF, DOC, XLS. Also, Gandcrab 4 removes all shadow copies and restore points. Despite this fact, the main method to decrypt .Krab files is restoring by special recovering software(see below in our article).
