The goal of this paper is to describe the idea and implementation of so
called passive covert channels (PCC), which might be used by malware to
leak information from the compromised hosts. This idea has been
implemented in a proof-of-concept tool, called NUSHU. The primary goal
of the PCC is to be as stealth as possible by not generating its own
traffic at all. To be actually useful PCC should be combined with some
kind of password sniffer or other information gathering software running
on the compromised host.
