Interesting and BIOS related.
"The specialists at ANT, which presumably stands for Advanced or Access
Network Technology, could be described as master carpenters for the NSA's
department for Tailored Access Operations (TAO). In cases where TAO's usual
hacking and data-skimming methods don't suffice, ANT workers step in with
their special tools, penetrating networking equipment, monitoring mobile
phones and computers and diverting or even modifying data. Such "implants,"
as they are referred to in NSA parlance, have played a considerable role in
the intelligence agency's ability to establish a global covert network that
operates alongside the Internet."
"The ANT division doesn't just manufacture surveillance hardware. It also
develops software for special tasks. The ANT developers have a clear
preference for planting their malicious code in so-called BIOS, software
located on a computer's motherboard that is the first thing to load when a
computer is turned on."
