Senrio CTO and founder Stephen Ridley told SCMagazine.com that researchers are more able to discover “the hallmark of a specific attack” following the release of code containing exploits affecting Cisco products. Companies have likely been observing the behavior of their network traffic, he said. He told SCMagazine.com that he suspects new vulnerabilities “could have been discovered” through an examination of network traffic in the wild. The "1-day" tactic used to be primarily an offensive tool, he said, referring to the process of reverse engineering a vulnerability from a manufacture's patch. "1-days" are highly valuable, Ridley noted, especially concerning networking equipment and embedded devices due to difficulties applying patches to embedded systems.
