Maze, Egregor, and Sekhmet ransomware decryption keys published

A decryptor has been launched for the Maze, Egregor, and Sekhmet ransomware households in one more signal that cybercriminals are rattled by latest regulation enforcement motion.

Maze was as soon as thought of one of the vital lively and infamous data-stealing ransomware teams. The gang, which started working in Could 2019, gained infamy for introducing the double-extortion mannequin, through which hackers first exfiltrate a sufferer’s knowledge and threaten to publish the stolen information except the ransom was paid. Typical ransomware teams infect a sufferer with file-encrypting malware and maintain the information in trade for cryptocurrency.

The group, which introduced that it was shutting down in November 2020, claimed numerous high-profile victims, together with Cognizant, Xerox, LG, and Canon.

Egregor emerged in September 2020 because the Maze operation started shutting down and employed the identical double-extortion approach as its predecessor. Regardless of claiming numerous victims — together with Ubisoft, Barnes & Noble, Kmart, and Vancouver’s subway system — the operation was short-lived, as a number of members of Egregor have been arrested in Ukraine in February 2021.

Sekhmet, which launched in March 2020, shares numerous similarities with Maze and Egregor. Though it emerged earlier than the latter, cybersecurity researchers have noticed related techniques, obfuscation, API calls and ransom notes between the 2.

On Wednesday, somebody figuring out themselves as “Topleak,” who claims to be the developer for all three operations, launched decryption keys for all three ransomware households in a Bleeping Pc discussion board submit.

“Since it would increase an excessive amount of clues and most of them will likely be false, it’s essential to emphasise that it’s deliberate leak, and don’t have any any connections to latest arrests and takedowns,” TopLeak stated, including that none of their group members will ever return to ransomware and that they destroyed all the supply code for his or her ransomware.

Emsisoft, which confirmed that the decryption keys are official, has launched a decryptor to permit any Maze, Egregor, and Sekhmet victims to recuperate their information at no cost.

Emsisoft ransomware knowledgeable and risk analyst Brett Callow advised TechCrunch that the discharge of the decryption keys is one other signal that cybercriminals are rattled.

“Whereas the gang claims their choice to launch the keys has nothing to do with the latest arrests of REvil — yeah, proper. The fact is that their prices and dangers are each growing,” stated Callow. “Ransomware grew to become such a giant drawback as a result of cybercriminals have been in a position to function with nearly full impunity. That’s now not the case. Whereas the issue is way from solved, there’s now way more ‘threat’ within the threat/reward ratio.”
