This assessment is based in part on the attack telemetry and malware used by the attackers and the emails received by victims. Midnight is itself a fake scheme likely cooked up by Royal. Victims of this fraud campaign receive emails claiming the Midnight Group was behind the original ransomware attack and their data will be posted on the dark web if they do not pay. The group's claims to have infected victims with ransomware appeared fake. The scheme may have even concocted a fake ransomware group: the Midnight Group. The firm last month identified a spam campaign that appears to trace to Royal and that layers on the deception, first by falsely notifying victims that a ransomware group has attacked them and then by pressuring them into opening a file that purportedly lists what was stolen but is a malware loader. The Royal ransomware group - another offshoot of the disbanded Conti group - appears to have targeted over 1,000 organizations with a social engineering attack designed to trick victims into trusting the attackers. District Court for the Eastern District of New York by the three plaintiffs details a history of unlicensed versions of Cobalt Strike being used by hackers to pave the way for ransomware attacks by the likes of LockBit and Conti and its many spinoff groups. "Instead of disrupting the command and control of a malware family, this time we are working with Fortra to remove illegal legacy copies of Cobalt Strike so they can no longer be used by cybercriminals, said Amy Hogan-Burney, general manager of Microsoft's Digital Crimes Unit. The order affects server internet protocol addresses hosted by data centers across the United States and a slew of malicious domains. federal court order redirecting into sinkhole servers the internet traffic from Cobalt Strike-infected computers sent to command-and-control centers controlled by bad actors. Now, Cobalt Strike maker Fortra, Microsoft and the Health Information Sharing and Analysis Center have obtained a U.S. Google in late 2022 released code allowing antivirus engines to detect it. federal agencies have issued repeated warnings, particularly to the health sector, to be vigilant for its presence. A common thread in ransomware incidents is hackers' use of penetration testing tool Cobalt Strike.
