How to remove GANDCRAB V5.0.5 Ransomware and decrypt .[5-6-7-8-9-random-letters] files

Standard

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.

How to remove GandCrab v5.0.4 Ransomware and decrypt .[random-letters] files

Standard

GandCrab V4 Ransomware fourth generation of notorious GandCrab Ransomware. Virus uses complex combination of AES-256 (CBC-mode), RSA-2048 and Salsa20 encryption algorithms. This particular version adds .KRAB extension to encrypted files and creates slightly different ransom note called KRAB-DECRYPT.txt. GandCrab V4 Ransomware demands ransom in BitCoins. Usually, it varies from $200 to $1000. Malware encrypts all types of files except ones in the whitelist and some necessary for Windows operation. All photos, documents, videos, databases get exncrypted after indection. Virus uses WMIC.exe shadowcopy delete command to remove shadow copies and reduce the chances of recovery. Unfortunately, at the moment we write this article, current decryption tools cannot decrypt GandCrab V4 Ransomware, but we will still provide links to this utilities as they can be updated any day.

How to remove GandCrab V3 Ransomware and decrypt .CRAB files

Standard

GandCrab V3 Ransomware is another generation of high-risk GandCrab virus, that uses AES-256 (CBC-mode) + RSA-2048 encryption algorithms. This version also appends .CRAB extensions to all encrypted files. GandCrab V3 creates similar CRAB-DECRYPT.txt file with changed ransom note. Unlike previous versions GandCrab V3 Ransomware uses carder.bit as a server and Psi-Plus Jabber for communication. It also modifies desktop background with unpleasant inscription. Ransomware restarts the computer after encryption is finished, and creates autorun key in the registry to run on Windows startup and attack newly created files. Ransom amount is ~$1000 and can be paid in Dash or BitCoin. Virus creates counter and deadline after which ransom amount can double.

How to remove GandCrab2 Ransomware and decrypt .CRAB files

Standard

GandCrab2 Ransomware is a virus, that uses AES (CBC-mode) algorithm to encrypt user files. During the process ransomware adds .CRAB extension to encrypted files. Following successful encryption, GandCrab2 creates CRAB-DECRYPT.txt file. Unfortunately, due to using TOR payment pages, NameCoin servers and cryptocurrency, there is no way to track the hackers, unless they make a mistake. Decryption key of previous version of GandCrab became public due to data leakage from their servers. GandCrab2 Ransomware asks 0.5 – 0.8 Dash (cryptocurrency) , which is less then before, however it still can estimate from several hundreds to more than thousand dollars.

How to remove GandCrab Ransomware and decrypt .GDCB files

Standard

GandCrab Ransomware is file encrypting virus, that uses AES-256 (CBC-mode) encryption algorithm to encode user files. It affects documents, media files, databases – the most important data for users. During encryption process ransomware appends .GDCB extension to encrypted files. After it finishes GDCB-DECRYPT.txt is created. GandCrab Ransomware targets 64-bit systems in Western Europe and South Korea. Its developers demand 1.5 – 2 Dash (cryptocurrency) which estimates in more than $1100. GandCrab checks the system for the presence of .exe files of antiviruses from the popular vendors, and won’t run on the computers with such security software or will attempt to disable it.
