Threat Database Ransomware Rrbb Ransomware

Rrbb Ransomware

The popularity of the STOP/Djvu ransomware strain among cybercriminals continues to remain strong and the evidence for it is the constantly growing number of variants being uncovered by infosec researchers. One such threat is Rrbb Ransomware. Despite being yet another variant, the threat's capacity to cause damage is undeniable.

Once executed on the breached computer system, Rrbb Ransomware will be responsible for encrypting the vast majority of the data stored there. The victim's documents, archives, databases, and other important files will all be left in an unusable state. The malware marks each encrypted file by adding '.rrbb' to that file's original name. Upon locking all targeted file types, Rrbb Ransomware will create a text file named '_readme.txt' on the device. The role of the text file is to contain a ransom note with the demands of the threat actors.

Ransom Note Details

The ransom-demanding message of the threat follows closely the established formula observed in other STOP/Djvu variants. It states that victims who wish to receive the decryption tool and necessary decryption keys from the cybercriminals will need to pay a ransom of exactly $980. However, if users contact the attackers within the first 3 days following the breach, they will only need to pay half of that. Two email addresses can be used for communication - '' and '' Of course, contacting and negotiating with cybercriminals is strongly discouraged as doing so can expose users to additional privacy or security risks.
