PFP Cybersecurity, a startup with roots in academia and the military, 
seeks out malware by analyzing the performance of hardware - not software 
and not the behavior of devices on the network.

PFP’s system compares ongoing radio-frequency output from processors to a 
baseline that is established when the device is known to be performing 
legitimate tasks. When it detects anomalies that might represent malicious 
activity, it triggers alarms. Then it’s up to other tools to figure out 
what exactly is behind the problem.

The system could be used to keep an eye on a large number of similar 
devices all performing the same task, such as those found in supervisory 
control and data acquisition (SCADA) networks that support power grids, 
chemical plants and the like. Savannah River National Laboratory is 
considering the gear for to protect its smart-grid relays.

The system could also be used to check new devices as they are delivered 
from the plants where they are made in order to find faulty ones or ones 
that have been tampered with, the company says.
