Lkfr Ransomware Will Encrypt Victim Files

Lkfr was identified during the examination of recent malware samples. It has been established that Lkfr is part of the Djvu ransomware family. This particular variant encrypts files and alters their filenames by appending the ".lkfr" extension. For example, a file originally labeled as "1.jpg" is transformed into "1.jpg.lkfr," and "2.png" is modified to "2.png.lkfr."

In addition to the file encryption process, Lkfr generates a ransom note presented as a "_readme.txt" file. Given its association with the Djvu family, there is a potential for threat actors to employ data stealers to extract information before initiating the file encryption with Lkfr. The victim is notified that all their files, encompassing pictures, databases, and documents, have undergone encryption using a robust algorithm and a unique key. The sole method for file recovery involves obtaining a decryption tool and a specific key.

The message introduces a time-sensitive discount and provides two email addresses for communication, providing a 72-hour time frame for victims to potentially make use of that discounted ransom amount.
