Irfk Ransomware

Cybersecurity researchers have detected another threatening variant from the prolific STOP/Djvu ransomware family. The new threat is named Irfk Ransomware and although it doesn't exhibit any significant improvement over the other variants of the STOP/Djvu family, its ability to cause damage should not be underestimated. More examples of ransomware threats are Hep, Mallox and Rugi.

If Irfk is deployed on the targeted devices successfully, it will initiate a strong encryption process. As a result, the vast majority of files stored there - documents, PDFs, archives, databases, etc., will be rendered unusable and inaccessible. All affected files will have '.irfk' appended to their original names as a new file extension. Upon encrypting all suitable files, the threat will proceed to drop its ransom note. The instructions from the attackers will be placed inside a newly-created text file named '_readme.txt.'

Irfk Ransomware's Demands

It appears the Irfk Ransomware uses the same template for its ransom-demanding message as the rest of the threats from this family. It states that the sum victims must pay to receive the required decryption key and software tool is $980. However, if the users establish contact within the first 72 hours of the ransomware attack, the price will supposedly be dropped down by 50% to $490.

The note also mentions that the hackers are willing to demonstrate their ability to restore the locked data by decrypting a signal non-important file for free. According to the note, users will have to message one of the two provided email addresses - 'manager@mailtemp.ch' and 'helprestoremanager@airmail.cc.'

The entire set of instructions dropped by Irfk Ransomware is:
