Security News > 2023 > January > Freedom for MegaCortex ransomware victims – the fix is out

An international law enforcement effort has released a decryptor for victims of MegaCortex ransomware, widely used by cybercriminals to infect large corporations across 71 countries to the tune of more than $100 million in damages.

The decryptor, built by Europol, cybersecurity firm Bitdefender, the NoMoreRansom Project, the Zürich Public Prosecutor's Office and the Zürich Cantonal Police, allows victims to recover files for free.

Victims with data encrypted by versions 2 through 4 need the ransom note present.

MegaCortex V1 decryption requires the presence of the ransom note and TSV log file created by the ransomware.

The MegaCortex decryptor follows the release of a similar tool, this one to help recover files encrypted by LockerGoga ransomware, developed by the same coalition of law enforcement and infosec groups.

According to Europol, the miscreants often spent months on the compromised networks without being detected, allowing the crooks to scope out vulnerabilities before dropping ransomware to monetize the attack.
