Romanian cybersecurity agency Bitdefender has launched a free decryption software for MortalKombat, a months-old pressure of ransomware concentrating on predominantly cryptocurrency customers.
MortalKombat, named after the favored online game franchise, was first noticed by Cisco Talos researchers in January. The researchers stated that the financially motivated gang had been deploying the ransomware to steal cryptocurrency from victims in the US, the UK, the Philippines, and Turkey.

As soon as put in on a sufferer’s machine, the malware seeks out cryptocurrency wallets on the gadget and displays the pc’s clipboard for pockets addresses. If a pockets deal with is discovered, the deal with is shipped to the attacker’s server and substituted with an attacker-controlled deal with in an try to hijack future transactions.
Although it’s solely been energetic for just a few months, Bitdefender on Tuesday introduced that it had launched a free decryptor for MortalKombat, enabling victims of the ransomware to unscramble their encrypted recordsdata without cost.
Bitdefender tells TechCrunch that it has additionally been observing the MortalKombat since January, however stated the magnitude of the menace stays unknown.
“That is an rising piece of ransomware that’s nonetheless distributed in the intervening time of writing,” Bogdan Botezatu, director of menace analysis and reporting at Bitdefender, advised TechCrunch. “We don’t have adequate information at this level to estimate the magnitude of the assault.

We imagine that the demanded ransom varies from an infection to an infection based mostly on how necessary the ransomed information is to the consumer or to the enterprise.”
Bitdefender declined to say the way it obtained the keys to create the MortalKombat decryptor or whether or not it was assisted by regulation enforcement.
To this point, the cybersecurity firm has launched 32 decryptors, together with ones for GandCrab, Darkside, LockerGoga, MegaCortex, and REvil, and estimates that it’s helped to save lots of ransomware victims some $1.6 billion in whole.
