Cybercriminals have unleashed a new ransomware threat that is capable of impacting a wide range of file types and leaving them in an unusable state. Like most ransomware, this LOCKEDFILECR threat also utilizes an encryption routine with a sufficiently strong cryptographic algorithm. The goal of the threat actors is to use the encrypted files as leverage to extort hefty sums of money from their victims.
When this particular malware threat encrypts a file, it will mark it by appending '.LOCKEDFILECR' to the file's original name. When all targeted file types on the breached device have been processed, the threat also will drop a ransom note with instructions from its operators. The ransom-demanding message will be delivered to the infected systems as a text file named 'ReadMe.LOCKEDFILECR.txt.'
The text of LOCKEDFILECR Ransowmare's message suggests that the threat is mostly deployed on corporate targets. Indeed, the attackers claim to have collected vast amounts of data - over 2 TB, that will be released to the public. The collected data also will supposedly be leaked to clients of the victims. To prevent this outcome, the affected organizations are given 72 hours to contact the cybercriminals on their dedicated websites hosted on the TOR network.
