As per Insurance Journal, BlackCat gained infamy through a series of high-profile cyber attacks targeting US and European companies and organizations.
Notable incidents include cyberattacks on Las Vegas casinos, impacting major entities such as MGM Resorts International and Caesars Entertainment Inc. The group was also implicated in a breach affecting the UK's Barts Health NHS Trust.
Rise to Notoriety
The gang garnered attention in 2022 with disruptive attacks on the energy sector, specifically targeting Luxembourg-based Creos Luxembourg and its parent company Encevo SA.
The impact extended to companies like Mabanaft GmbH & Co. KG and Oiltanking GmbH Group, causing payment disruptions at filling stations and forcing firms to declare force majeure on supplies.
Significant Victory For Cybersecurity
Charles Carmakal, Consulting Chief Technology Officer at Mandiant's consulting arm, emphasized the magnitude of this achievement, calling it a "huge win for law enforcement and the community."
While acknowledging the possibility of BlackCat's associates continuing hacking activities, Carmakal stressed that the takedown sends a robust message about police action.
"In disrupting the BlackCat ransomware group, the Justice Department has once again hacked the hackers. With a decryption tool provided by the FBI to hundreds of ransomware victims worldwide, businesses and schools were able to reopen, and health-care and emergency services were able to come back online," Deputy Attorney General Lisa Monaco said in a statement.
BlackCat's Modus Operandi
Known for their sophistication and innovation, BlackCat's members operated in Russia and recruited affiliates on cybercrime forums. These associates rented out the ransomware to hacking companies, installing malware that encrypted files, demanded cryptocurrency payments, and threatened to publish stolen internal documents if payment was not received.
Speaking of BlackCat ransomware, our previous report in August indicated that a new variant dubbed "Sphynx" had been exploiting Remcom and Impacket. These are two tools that help the hackers compromise the networks.
