NSA reportedly planted spyware on electronics equipment

According to the report, the NSA has planted backdoors to access computers, hard drives, routers, and other devices from companies such as Cisco, Dell, Western Digital, Seagate, Maxtor, Samsung, and Huawei.

The ANT department prefers targeting the BIOS, code on a chip on the motherboard that runs when the machine starts up. The spyware infiltration is largely invisible to other security programs and can persist if a machine is wiped and a new operating system is installed.
