Signed software abused to deploy antivirus-killing scripts
Security researchers have exposed a digitally signed adware campaign that silently disables antivirus protections by deploying SYSTEM-privileged payloads via an MSI/PowerShell updater built with Advanced Installer. In a single day, about 23,500 hosts in 124 countries were infected, including networks in academia, government, utilities, and healthcare, with the operator Dragon Boss Solutions LLC. The campaign uses PUPs branded as browsers, downloads an MSI disguised as a GIF, and runs ClockRemoval.ps1 to disable security products and block updates, raising the risk of more dangerous payloads; admins are urged to hunt for specific artifacts (MbRemoval/MbSetup, WMI subscriptions, and suspicious hosts-file changes) and to monitor unregistered update domains.

The issue affects a narrow set of enterprise configurations involving BitLocker on the OS drive, a PCR7-based TPM validation policy, and certain Secure Boot states, and is unlikely to impact typical consumer devices. Workarounds include removing the PCR7 Group Policy before updating or applying a Known Issue Rollback; Microsoft is developing a fix.
