Malware uses Intel AMT to bypass Windows Firewall


Recommended Posts

Saw an interesting article a few days ago about a vulnerability in intel's Active Management Technology (AMT). It uses Serial-over-LAN (SOL) to hide communications from the firewall. This feature creates a virtual serial port for sending and receiving data from an authenticated management console. Basically rather than using the host's networking stack hackers have managed to have malware diverted to the AMT chipset and virtual serial driver. Apparently technically it is not a vulnerability, and is simply misusing the feature on an already compromised network. Administrative rights are apparently needed for this to work.
