GandCrab V5.0.5 Ransomware is fifth generation of high-risk GandCrab Ransomware. Probably, this virus was developed in Russia. This crypto-extortor encrypts user and server data using the Salsa20 algorithm, and RSA-2048 is used for auxiliary key encryption. 5-th version appends .[5-random-letters] extension to encrypted files and creates ransom note called [5-random-letters]-DECRYPT.txt. Examples of ransom notes: VSVDV-DECRYPT.html, FBKDP-DECRYPT.html, IBAGX-DECRYPT.html, QIKKA-DECRYPT.html. GandCrab V5.0.5 Ransomware demands $800 ransom in BitCoins or DASH cryptocurrencies for decryption. However, often, malefactors deceive users and don’t send keys. Thus, victim won’t recover her/his files, but put credentials at risk on doubtful exchange of cryptocurrencies.
