GandCrab2 virus Removal Guide
What is GandCrab2 ransomware?
GandCrab v2 – the second version of the notorious ransomware virus which is asking 500 USD to recover victim's files
GandCrab2 virus - dangerous ransomware which is asking $500 for the special decryption key which is needed to recover encrypted files.
GandCrab v2 ransomware is a cryptovirus which has been developed soon after the GandCrab – one of the most aggressive forms of ransomware. Just like its predecessor, the new version is distributed via Seamless malvertising campaign leading victims to RIG exploit kit. Nevertheless, it can also be disguised under HoeflerText Font Update scam pop-ups. Upon successful infiltration, ransomware appends .CRAB file extension to each locked file and generates a CRAB-DECRYPT.txt ransom note.
|The predecessor||Gandcrab ransomware|
|Ransom amount||500 USD|
|Elimination||Use ReimageIntego to get rid of Gandcrab or any its versions|
The malware redirects its victims to TOR site, which contains instructs the victim what they have to do to decrypt locked files. While the original variant of GandCrab2 demanded 1200 USD in Dash coins, the new version detected at the beginning of March 2018 asks for 500 USD in Dash coins.
However, specialists mock the attempt of GandCrab2 virus developers to maximize profit since the virus can be decrypted using a free GandCrab decryptor available at NoMoreRansom. However, crooks provide a link to a decryption tutorial on NoMoreRansom and scare people by falsely claiming that the tool won't decrypt files. Contrary, it will make data undecryptable. Nevertheless, experts point out that the GandCrab2 (version 1.0.0r) and the GandCrab (v2.3.*) belong to the same group and can be decrypted in the same way.
To protect yourself from GandCrab2 ransomware attack, be careful with .doc file email attachments. Despite the fact that such spam emails can be sent by official authorities or other pretend-to-be legitimate sources, by opening a .doc file attached to a suspicious email can run a PowerShell script, which creates a sct5.txt or 128384.txt file, which connects to the remote server and download the ultimate GandCrab2 ransomware payload. In case of HoeflerText Font Update scam attack, the system gets infected with Font_Update.exe file, which subsequently downloads a g.js scrip and remote access tool known as NetSupport Manager remote access utility, which executes the ransomware completely.
Those whose files have already been encrypted by .CRAB file extension virus should immediately remove GandCrab2 virus. For this purpose, we recommend using ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes tool as they are powerful enough to detect and neutralize all related components. Following successful GandCrab2 removal, you should download a free decryptor provided in NoMoreRansom and decrypt your files with it.
The first sign that your PC has been infected with GandCrab2 virus is .CRAB file extension attached to personal files
Cybercrooks distribute viruses via malspam campaigns and fake updates
The developers of malicious cyber infections are accustomed to the use of exploit kits. Their purpose is to detect the vulnerabilities on the targeted system and open the back door for the cyber infections to enter the system quickly. This particular ransomware relies on the combination of two exploit kits – RIG and GrandSoft.
Typically, people are exposed to the exploit kits by sending them malicious emails with infected .doc file attachments. Spam emails are developed in a way to mimic well-known brands or official institutions. In this particular case, people get an email message with the subject Receipt Feb-21310 [ random numbered] sent by [ransom name ]@cdkconstruction.org. Most of the victims reported that such email does not expatiate on the subject, but only indicate the fact that “DOC attached.” Beware that the type of the attached file might also differ, but usually, the file extension is somewhat suspicious ( .EXE, .COM, .PIF, .SCR, .HTA, etc.).
Apart from malspam, people can end up with this ransomware after downloading a fake “Chrome Font Pack” on hacked websites. People can be exposed to compromised domains by mistyping domain's name or after clicking on infected ads. The hacked website displays a scrambled text by default and generates a notification saying that “The “HoeflerText” font wasn't found” and urges people to install the fake font pack to see the content of the website normally.
GandCrab2 removal tutorial
Manual GandCrab2 removal is not possible. In general, ransomware virus cannot be eliminated manually as they inject multiple files, corrupt registries, change startup settings, and initiate other system's changes to evade easy detection and removal.

How to prevent from getting ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
