Ransomware which is associated with the .7h9r file extension has been reported to affect users on a massive scale. The ransomware uses an extremely strong file encryption to encode the files of infected users. In addition to that, 7h9r leaves a ransom note and asks users to contact email@example.com address for negotiation on the payoff of the files. All users who have been affected by this ransom virus should immediately remove it from their computer instead of paying any ransom. To decode your files, unfortunately, direct decryption is so far impossible unless the ransom is paid. However, we will update this article as soon as there is a decryptor released and in the meantime you may want to try using the step-by-step instructions posted in this article to use several methods to go around direct decryption and try to restore your files.
|Short Description||The ransomware encrypts files with the RSA or AES algorithms and asks a ransom for decryption.|
|Symptoms||Files are encrypted and become inaccessible. A ransom note with instructions for paying the ransom shows as a “README_.txt” file.|
|Distribution Method||Spam Emails, Email Attachments, File Sharing Networks.|

7h9r Ransomware – Distribution Method
To infect users with a relatively high success rate, 7h9r crypto ransomware may use different strategies. One of the most often used strategies is via spam e-mail messages. Since most e-mail services tend to scan for and block malicious attachments, 7h9r ransomware may use URLs that redirect to the malicious Web link which may infect users via several methods:
7h9r Ransomware – Malicious Activity Overview
The notorious 7h9r Ransomware virus has been reported by several researchers to create malicious files typically in one of the following Windows directories:
After this has been done, 7h9r ransomware virus may modify the registry editor of Windows with a purpose of running its malicious encryption module when Windows starts. The usually targeted keys for this are the following:
After running, the encryptor begins to encrypt files that contain the following file extensions:
After encrypting the files, 7h9r Ransomware makes sure that the user knows what he or she is dealing with. It adds its trademark – the .7h9r extension and an encrypted file appears with a removed icon and a name, similar to the following example:
→ New Text Document.txt.7h9r
After this, 7h9r begins to communicate. It drops a “README_.txt” file which states the following ransom message:
→ “Your files were encrypted. If you want to decrypt them you must send code WE8765twx1009jdR|742|0|2 to email firstname.lastname@example.org.
Then you will receive all necessary instructions. Attempts to decipher on their own will not lead to anything good, except irretrievable loss of information.
If you still want try to decipher them, please make a copy of files, this is our life hacking for you. (If you change the file we can’t decrypt them in future)” Source: Infected User
In brief, this ransomware is most likely created to convince users to contact the e-mail of the cyber-criminals to beg for their files. Upon contact, the crooks may provide instructions on how to make a ransom payoff most likely in BitCoin after which the cyber-criminals may provide a decryption key. So far, it is a mystery on what algorithm has been used to encrypt the files, but researchers believe that the AES and RSA may be utilized in combination.
