According to an article published by Germany’s Der Spiegel newspaper on Sunday, the National Security Agency (NSA) has a catalog of "backdoors" that allows spies to infiltrate equipment from major computing and security vendors including firewalls from Juniper Networks, hard drives from Western Digital, Seagate, Maxtor and Samsung, networking gear from Cisco and Huawei, and unspecified equipment from Dell.
The report does not indicate that any of the named companies were cooperating with the NSA and that all of this was done without their knowledge or permission. The new information comes from documents included in the Edward Snowden cache leaked to various publications.
The internal NSA catalog offers rigged monitor cables for spying on targets’ monitors ($30), base stations for tricking mobile networks and cellphones ($40,000), and even bugs disguised as USB plugs ($20,000+). These are all products of the Advanced/Access Network Technology (ANT) division of the NSA’s Tailored Access Operations (TAO) elite hacker unit. According to the Der Spiegel, ANT also has techniques for infecting BIOS firmware.
