Der Spiegel published an internal NSA catalog that offers spies backdoors into a wide range of equipment from major IT vendors. The document includes backdoors for hard drives from Western Digital, Seagate, Maxtor and Samsung, for Juniper Networks firewalls, networking appliances from Cisco and Huawei, and unspecified equipment from Dell. The catalog even lists the prices for these electronic break-in tools, with costs ranging from free to $250,000. The articles also reveal how the NSA and its allies tapped major undersea cables analyzing bulk internet traffic.”]
