And from one firmware revision to another? Could you make that change with a #pragma in the code or something like that? *From:* full-disclosure-bounces () lists grok org uk [mailto: full-disclosure-bounces () lists grok org uk] *On Behalf Of *Thor (Hammer of God) *Sent:* Sunday, December 19, 2010 12:18 PM *To:* Craig Heffner; full-disclosure () lists grok org uk *Subject:* Re: [Full-disclosure] Default SSL Keys in Multiple Routers These manufacturers use the same key on each of their models?

T ------------------------------ *From: *Craig Heffner *Sent: *Sunday, December 19, 2010 5:56 AM *To: *full-disclosure () lists grok org uk *Subject: *[Full-disclosure] Default SSL Keys in Multiple Routers Many routers that provide an HTTPS administrative interface use default or hard-coded SSL keys that can be recovered by extracting the file system from the device's firmware. The LittleBlackBox project contains a database of over 2,000 (and growing) private SSL keys that are correlated with their respective public certificates, and hardware/firmware versions. While most of these certificates are from DD-WRT firmware, there are also private keys from other vendors including Cisco, Linksys, D-Link and Netgear. Private keys can be recovered by supplying LittleBlackBox with the corresponding public key. If the public key is not readily available, LittleBlackBox can retrieve the public certificate from a pcap file, live traffic capture, or by directly querying the target host. LittleBlackBox can be downloaded from http://littleblackbox.googlecode.com. More information is available at http://www.devttys0.com/2010/12/breaking-ssl-on-embedded-devices/.
