  1. I apologize for trying to spoil the fun, but so far we haven’t seen anything but marketing. The proper lead-in would be “Hacker claims to have written rootkit for Cisco’s routers”.

    Tcl-based IOS backdoors have been known for years and even I’ve written about ways to make a Tcl script into almost a daemon.

  2. Companies looking for a safe environment for purchasing used networking equipment should make sure they are dealing with a member of the United Network Equipment Dealer Association ( More than 300 members worldwide work together to promote and uphold the highest standards and best practices when it comes to buying and selling legitimate pre-owned gear from all the leading OEMs. Together, UNEDA members sell more than $2 billion in pre-owned gear annually to over 10,000 customers, fueled by an increased supply of and demand for pre-owned network routers, switches, access servers, security products and VoIP phones/telephony products at savings of up to 90 percent off OEM list prices.
