CryptXXX is ransomware crypto-virus. It encrypts user personal data with AES CBC 256-bit algorithm and asks for RSA-4096 key. Actually, CryptXXX Ransomware also steals bitcoins stored on the computer if there are any. Virus modifies names and extension of all encrypted files to .crypt, .cryp1 or .crypz, changes desktop wallpaper using de_crypt_readme.bmp (image with black background and white text), creates text file with instructions to pay the ransom (de_crypt_readme.txt), and html file with the same instructions (de_crypt_readme.html). Ransom is about 1.2 BitCoins or $400. CryptXXX Ransomware attacks data on local drives and attached storage devices. Ransomware makes a delay between the moment of infection and the start of encryption, which makes it more difficult to detect.
