US-CERT is aware of recent open source reports regarding possible counterfeit Cisco routers. US-CERT originally reported this activity in April 2006. Please note that US-CERT is re-releasing that information in this report for situational awareness purposes due to the new open source reporting and to provide methods for determining if a router is counterfeit.
Certain routers in the Cisco 2600 Router Series (2610XM, 611XM, 2620XM, 2621XM) and Cisco 1721 Modular Routers may be counterfeit. Cisco Systems has provided US-CERT with detailed information to assist organizations in determining if a router is counterfeit. Organizations may wish to check their 2600 and 1721 series routers. If organizations discover suspect counterfeit routers, they should contact US-CERT accordingly.
