FBI Warns of Rising Development of Twin Ransomware Assaults Concentrating on U.S. Firms – Supply:thehackernews.com

The U.S. Federal Bureau of Investigation (FBI) is warning of a brand new development of twin ransomware assaults concentrating on the identical victims, no less than since July 2023.

“During these attacks, cyber threat actors deployed two different ransomware variants against victim companies from the following variants: AvosLocker, Diamond, Hive, Karakurt, LockBit, Quantum, and Royal,” the FBI said in an alert. “Variants were deployed in various combinations.”

Not a lot is thought concerning the scale of such assaults, though it’s believed that they occur in shut proximity to 1 one other, starting from anyplace between 48 hours to inside 10 days.

“This use of dual ransomware variants resulted in a combination of data encryption, exfiltration, and financial losses from ransom payments,” the company stated. “Second ransomware attacks against an already compromised system could significantly harm victim entities.”

It’s value noting that twin ransomware assaults should not a completely novel phenomenon, with instances observed as early as Could 2021.

Then, earlier this month, Symantec detailed a 3AM ransomware attack concentrating on an unnamed sufferer following an unsuccessful try to ship LockBit within the goal community.

The shift in ways boils right down to a number of contributing factorstogether with the exploitation of zero-day vulnerabilities and the proliferation of preliminary entry brokers and associates within the ransomware panorama, who can resell entry to sufferer techniques and deploy varied strains in fast succession.

Organizations are suggested to strengthen their defenses by sustaining offline backups, monitoring exterior distant connections and distant desktop protocol (RDP) use, implementing phishing-resistant multi-factor authentication, auditing consumer accounts, and segmenting networks to stop the unfold of ransomware.
