removal by Lucia Danes - - | Type: Ransomware

Grovat ransomware is a cryptovirus that marks users' files with .grovat extension and demands ransom of $980 in Bitcoin

Grovat ransomware
Grovat ransomware is a file locker that targets databases, documents, pictures, and other files in order to prevent users from accessing them.

Grovat is a computer infection that belongs to ransomware category. These threats are introduced into the systems with various deceptive ways, such as fake updates, spam email attachments or hyperlinks, exploit kits, etc. Once inside, the malware performs a variety of system changes and then looks for databases, documents, pictures, videos and other personal files to encrypt using AES-256 cipher. Grovat virus then contacts a C&C server,[1] delivers a unique identifier along with decryption code assigned for each user and uploads a ransom note _readme.txt. In it, hackers explain what happened to victims' files and that they need to pay $980 ransom in Bitcoin, after contacting crooks via merosa@india.com or merosa@firemail.cc emails. Grovat ransomware stems from the notorious STOP/Djvu virus family, that has been one of the most widespread cryptoviruses worldwide.

Grovat ransomware is just one of many STOP virus variants that have been actively infecting users' computers worldwide. Among them, are such threats like Grovas, Tronas, Chech, Kropun, and many others. Hackers are keen to release these new variants because security researchers are continually working and decryption tool that can help victims to retrieve their files for free. Unfortunately, Grovat ransomware is currently not decryptable, although the chances are that it will be in the near future.

After entering the system, Grovat ransomware changes Windows registry to start running with every Windows boot. This assures prevalence. Additionally, it removes Shadow Volume Copies to prevent speedy recovery. Nevertheless, users still might be successful with tools like ShadowExplorer if this process fails. However, Grovat ransomware removal needs to be performed before file recovery attempt, or the data will be encrypted repeatedly.

During the encryption process, Grovat virus runs a fake Windows update pop-up, which deceives users, making them think that it is just another Windows update. However, once the fake patching is finished, users will find their files marked with the .grovat file extension, and that they cannot access any of their personal data anymore.

The ransom note _readme.txt states the following:

Do not contact bad actors behind the Grovat ransomware attack, as there is a high chance of being scammed. In such a case you would not only lose your personal files but also waste your money, all while sponsoring cybercriminal activity. Instead, remove Grovat ransomware from your device using anti-malware solutions like Reimage or Malwarebytes MalwarebytesCombo Cleaner. Check out our instructions below for more details.

If you are downloading insecure programs, make sure you scan it with appropriate tools before opening the executable

Third-party websites that distribute illegal software or its cracks are notorious for malware. While it is highly likely that owners of such sites like Pirate Bay or KickAss Torrents did not place malicious software onto their site purposely, there are many other vectors involved in the whole file-sharing scheme, and it makes file torrenting particularly dangerous.

Generally, experts[2] advise staying away from file-sharing sites that host illegal software or its cracks. However, users will always be keen on acquiring a piece of software for free instead of paying. Unfortunately, such actions might cost you much more – loss of all personal files, along with the money.

Nevertheless, if you do visit sites that are not particularly safe, make sure you use some precautionary measures. Employ anti-malware software with real-time scanning feature, along with Firewall, use ad-blocker and scan every executable you download with tools like Virus Total.

Also, make sure you patch your system with the latest security updates, use adequate protection for RDP[3] and all other accounts, use caution when opening spam emails and generally be careful when browsing the net.

Remove Grovat ransomware from your computer and only then attempt file recovery

Before you can attempt to recover the locked data, you need to remove Grovat virus from your device. While doing so manually is possible, extensive IT knowledge is required, and most regular users would not be able to perform such a complicated task. Therefore, download professional anti-malware software and run a full system scan. In case Grovat ransomware is tampering with the security application, you should access Safe Mode with Networking, as explained in our instructions below.

Once you complete Grovat ransomware removal, you can attempt file recovery. As we previously mentioned, there is no decryptor created for this variant yet. Thus, if you want to avoid paying crooks, you will have to wait until one is built. In the meantime, you can use alternative file recovery options – check them out below.
