Silver Fox Strikes Again: Hackers Exploit Microsoft-Signed Drivers to Sneak In ValleyRAT!
Silver Fox APT is creating chaos by abusing Microsoft-signed drivers, once considered safe, to install remote access tools. Their secret weapon? The WatchDog Antimalware driver, now a hacker’s dream for disabling security tools. It’s like letting the fox guard the henhouse—except the fox has a backdoor key and a tech degree.

Hot Take:
Ah, Microsoft-signed drivers, once the guardians of our systems, now moonlighting as double agents. Who knew the WatchDog would turn into a watchdog for cybercriminals? It’s like letting your guard dog borrow your Netflix account, only to find out it’s been binge-watching heist movies for tips on how to rob you blind. Who’s a good boy? Not these drivers, apparently.
Key Points:
- Silver Fox APT exploits Microsoft-signed drivers to bypass security.
- WatchDog Antimalware driver used to terminate antivirus processes.
- ValleyRAT backdoor deployed for surveillance and data theft.
- Attackers use modified drivers to evade detection.
- Security teams advised to go beyond signature and hash checks.
