Grej ransomware is another malicious program that has been released in active attack campaigns. The virus has been identified to belong to the Dharma/CrySiS family of threats. It is capable of adjusting essential system settings, lowering system security, and leaving personal files locked.
Encryption of personal files leaves them renamed and inaccessible. That impact serves hackers for extorting a hefty ransom fee for a .grej files decryption tool.
Beware that any negotiations with cybercriminals are better to be avoided. Keep up with this article to learn more information about the Grej ransomware virus, discover how to remove it step-by-step, and check out some alternative data recovery methods.

More About the Distribution of Grej Cryptovirus and Its Impact
Grej ransomware needs to install its payload file on a computer system to initiate the attack. The delivery of its payload on PCs happens via shady techniques like email spam campaigns, freeware with compromised installers, software cracks, malicious web links, and fake software update notifications. All those techniques attempt to convince people to download/install the malicious program without thinking that there is any hidden danger.
As soon as the Grej virus attack begins, the threat drops more malicious files and starts executing them one by one. The complex infection process it passes through results in lots of nasty changes. After it compromises essential system settings, it reaches the data encryption stage.
When the ransomware reaches this stage, it utilizes a built-in cipher module programmed to transform parts of the original code of target files with the help of a strong cipher algorithm. All unwanted changes prevent victims from accessing data stored by corrupted files. Corrupted files are all marked with a few specific extensions – an ID number, an email address (email@example.com) and the .grej suffix.
All of the following types of files may be encrypted by the threat:
- Audio files;
- Document files;
- Video files;
- Backup files;
- Image files;
- Banking credentials, etc.
Analyses of the code of Grej ransomware reveal that the ransomware misuses functionalities of registry keys as well. To control the automatic load of certain malicious files, the ransomware compromises the follwing directories:
Just like its predecessors (PB, OFF, Pause) this ransomware drops its ransom note files at the end of the attack. One of them appears on the screen as a pop-up window while the other stays somewhere on the infected machine under the name info.txt.
The ransomware creates these files to extort a ransom payment. Here is what the message in the second reads:
all your data has been locked us
You want to return?
write email firstname.lastname@example.org or email@example.com
Both messages have the purpose to persuade victims to transfer a ransom in cryptocurrency to hackers’ digital wallet. However, hackers who stand behind nasty Grej ransomware attacks should not be trusted. Otherwise, there is a risk that they will steal the money by providing no effective decryption solution. Hence, a ransom payment does not guarantee the recovery of .grej files. It is better to be avoided.
Remove Grej Ransomware
The so-called Grej ransomware is a threat with highly complex code that disrupts system security in order to encrypt personal files. Hence, the infected system could be used in a secure manner again only after you remove all malicious files and objects created by the ransomware. All steps presented in the ransomware removal guide below aim to help you to remove malicious files from your infected PC in full.
Beware that manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps navigate to the automatic part of the guide.
