Remove REHA Ransomware Virus (2023 Guide)

REHA ransomware is the 199th variant of DJVU file-encrypting virus

REHA ransomware virus is a malicious computer software that is designed to perform asymmetric encryption on victim’s personal files. The aim of this STOP/DJVU variant is to restrict access to personal data so that the cyber criminals could demand ransom payment. Upon data corruption, the ransomware appends .reha extensions to filenames and leaves _readme.txt note on desktop and other affected folders. The ransom note instructs paying $490 in the next 3 days or $980 if later. The ransom must be paid in Bitcoin to the cryptocurrency wallet specified by the criminals who can be contacted via helpmanager@firemail.cc or helpmanager@iran.ir.

REHA virus uses either ONLINE or OFFLINE keys to encrypt files. If you’re looking for a way to decrypt your files for free, the first thing you should do is look at your personal ID. You shouldn’t look at the ID specified in the _readme.txt note; instead, go to C:/SystemID/PersonalID.txt and check the IDs here. If one of them ends in t1, you’re subject to offline encryption, which means that STOP Decryptor will be able to recover your files one day. At the moment, the offline encryption/decryption keys for this variant are unknown, so you must stay patient.

It is extremely important to remove REHA ransomware virus as soon as you can. It tends to install AZORULT password-grabbing virus on the system. In other words, it means that it can steal and use your login information on all the websites you’re been registered on. Be careful as this might result in private data leakage or even financial loss.

The ransom demand

REHA ransomware virus leaves a threatening _readme.txt note which briefly explains that corrupted data cannot be recovered in any other way than paying the ransom. Paying the ransom will give the victim access to the private key (required for decryption) and a decryption software. However, the attackers tend to hide the fact that their virus sometimes uses offline key to corrupt data in case it fails to connect to its command&control server during the attack. This offline key is similar to all the versions of .reha extension malware, so when someone pays the ransom, the same key can be used for other victims.

For victims subject to the online ransomware key encryption, the data can be recovered ONLY from data backups. _readme.txt note explains that contacting the attackers via specified emails will provide instructions on paying the required sum of money and prove the existence of such decryption tool. The attackers suggest sending a couple of small encrypted files for immediate decryption as a proof of concept.

However, we STRONGLY recommend you not to pay the ransom as the criminals often tend to put a lot of effort in convincing victim to pay, but when it comes to fulfillment of their part, they can vanish in a moment.

Ransomware tends to hide in illegal file packs

STOP-DJVU ransomware variants such as REHA, NOSU, KODC, REDL and others are distributed alongside illegal downloads. In particular, they hide in software activation cracks, keygens, and other illegal downloads. For example, some victims have already reported downloading the malware alongside a version of KMSPico virus. Therefore, we strongly suggest avoiding such malware. Instead of choosing illegal tools, consider investing in legitimate version of software to keep your privacy and personal files safe and sound.

However, the majority of ransomware viruses are distributed via email spam. As a result, you must be careful when opening suspicious electronic letters as well. For instance, attackers tend to impersonate legitimate companies when distributing malicious spam to computer users. Therefore, if you have at least a tiny suspicion that there’s something not right with the email you received, do not click on links or attachments included in it.
