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.
This has a number of valuable advantages: an infected PC or server appears to be functioning normally, so the infection remains invisible to virus protection and other security programs. And even if the hard drive of an infected computer has been completely erased and a new operating system is installed, the ANT malware can continue to function and ensures that new spyware can once again be loaded onto what is presumed to be a clean computer. The ANT developers call this "Persistence" and believe this approach has provided them with the possibility of permanent access.
Another program attacks the firmware in hard drives manufactured by Western Digital, Seagate, Maxtor and Samsung, all of which, with the exception of latter, are American companies. Here, too, it appears the US intelligence agency is compromising the technology and products of American companies.
