PLATINUM continues to evolve, find ways to maintain invisibility

By Microsoft


Microsoft has come across an evolution of PLATINUM’s file-transfer tool, one that uses the Intel® Active Management Technology (AMT) Serial-over-LAN (SOL) channel for communication. This channel works independently of the operating system (OS), rendering any communication over it invisible to firewall and network monitoring applications running on the host device. Until this incident, no malware had been discovered misusing the AMT SOL feature for communication.
