Silver Fox Abuses Microsoft-Signed Drivers to Deploy RAT
⚠️ A newly discovered campaign attributed to the Silver Fox APT abuses trusted Microsoft-signed drivers to bypass security protections and install a remote access tool. Check Point Research found attackers used the WatchDog driver (amsdk.sys) and an older Zemana-based driver to terminate antivirus and EDR processes, enabling deployment of ValleyRAT. Researchers observed loaders with anti-analysis, persistence, embedded drivers and hardcoded lists of security processes, and warn that timestamp edits can preserve valid signatures while evading hash-based detection.
