BlackRose Ransomware

BlackRose Ransomware is a ransomware infection which, unlike some highly complex ransomware threats, only encrypts files. File encryption is one of the most noticeable symptoms of ransomware, but deep inside the system multiple complex changes are made. In the case of the BlackRose Ransomware, no changes in the registry or other parts of the operating system have been observed. The BlackRose Ransomware encrypts files and creates a .txt containing a so-called ransom note, which provides information of what should be done in order to regain access to the encrypted data. It is crucial to ignore the demand provided as it is unlikely that the damaged data will be decrypted.

Even though the BlackRose Ransomware lacks some typical features, it does encrypts mostly used files, including images and documents. After encryption, the compromised files can be recognized by the file extensions .jpg.okokokokok, .jpg.ranranranran, and .jpg.whatthefuckm appended. To intimidate the user of the victimized computer, the ransomware drops a ransom message in the text file named READ_IT_FOR_GET_YOUR_FILE with the following message:

Files has been encrypted
Send me some 1 bitcoins or more
to Address BITCOIN :

After Payment bitcoin please send your Address Bitcoin Payment to me at


I will give File Decryptor for you in 24HR...

As the ransom suggest, the victim is supposed to buy bitcoins, digital currency, and send the money to a specific wallet. According to the attacker, the victim has to pay 1 bitcoin, which is over 1,000 US dollars. The transaction is supposed to be made within 24 hours, and after receiving the payment the attacker promises to send a program named File Decryptor. The name of the program suggests that that program is an executable which decrypts the encrypted files. The odds are that such a program does not even exist but is mentioned in order to persuade victims that they have a chance to get control over their data.

As for the email address black-rose@outlook.co.th, the domain extension co.th suggests that the attacker might be located in Thailand. Moreover, the file name extensions added may also be a clue about the identity of the attacker; however, no research on that have been carried out so far. In any case, there is no reason for following the instructions provided by the attacker as the BlackRose Ransomware has to be removed from the computer.

The wording of the message and the way the BlackRose Ransomware works suggest that the attacker behind the infection has only started out on a career as a hacker. There are multiple similar cases of ransomware when a little number of computers is affected. Even though such ransomware infections stop being distributed at some point, they do cause harm, which can be prevented.
