The latest variant of the Sysrv botnet malware is menacing Windows and Linux systems with an expanded list of vulnerabilities to exploit, according to Microsoft.

Despite being less active, which may suggest that the ransomware business is closer to moonlighting, OldGremlin has demanded ransoms as high as $3 million from one of its victims.

"Just a few hours of compromise could result in profits for the perpetrators. That's why we're seeing a continuous fight for cloud CPU resources. It's akin to a real-life capture-the-flag, with the victim's cloud infrastructure the battleground," said Stephen Hilt, Senior Threat Researcher at Trend Micro. Threat actors are increasingly scanning for and exploiting these exposed instances, as well as brute-forcing SecureShell credentials, in order to compromise cloud assets for cryptocurrency mining, the report reveals.
Security researchers are warning of a relatively new malware loader, that they track as Verblecon, which is sufficiently complex and powerful for rannsomware and erespionage attacks, although it is currently used for low-reward attacks. Researchers from Symantec, a division of Broadcom Software, discovered Verblecon in January last year and observed it being used in attacks that installed cryptocurrency miners on compromised machines.
The Lapsus$ data extortion group has released what they claim to be data stolen from the Nvidia GPU designer.
