The BlackBit Ransomware matches closely a previously identified and analyzed threat named Loki Locker Ransomware. Despite this fact, users should not underestimate the threat's capacity to cause damage. If successfully deployed onto breached devices, BlackBit will activate its encryption routine and leave most of the data stored there in a completely unusable state. The threat will change the names of the targeted files, as well as their default icons, set a new desktop background image, and create two new files named - 'info.hta' and 'Restore-My-Files.txt.'
The new names of the locked files will now include an email address - 'firstname.lastname@example.org,' an ID string generated specifically for the victim and '.BlackBit' as a file extension. Three different ransom notes will be left for the victims. First, a message will be displayed on the new desktop wallpaper. Then, a pop-up window created from the .hta file will display the main ransom-demanding message. A shorter version of the ransom note will be delivered inside the text file.
In general, the instructions of the cybercriminals provide victims with three ways to initiate communication - two email addresses at 'email@example.com' and 'firstname.lastname@example.org,' and a Telegram account at '@Spystar_Support.' The hackers specify that they will only accept ransom payments made using the Bitcoin cryptocurrency. Affected users are given a set amount of time to pay the demanded ransom or supposedly have their data deleted and the hard disk suffering serious damage. The operators of the BlackBit Ransowmare state that they are willing to decrypt up to 3 files for free. One of the messages warns that deleting a file named 'Cpriv.BlackBit' will result in permanent data loss. Of course, trusting the words of cybercriminals is not recommended, and communication with such individuals or organizations carries significant privacy and security risks.
The ransom note displayed in a pop-up window is:
