RegretLocker ransomware is a type of malware that encrypts all victims’ personal files with military-grade algorithms upon infecting users’ computer systems. After the encryption is complete, a ransom note usually appears in contaminated folders. In this case, a “HOW TO RESTORE FILES.txt” file can be found.
RegretLocker ransomware virus appends all non-system files with an extension .mouse. Infected files cannot be opened. The ransom note is very brief. The cybercriminals inform the victim that its files were encrypted, and if they want to retrieve the data, they should contact the perps via email at firstname.lastname@example.org. Also, a unique hash is given to be provided upon contact. Further details, like ransom amount, would be delivered after contacting the cyberthieves.
