When a CISO pays good money for a thorough pentesting, she wants results. Not necessarily the ones that the pentester had in mind, either. Whether the time allotted is too short, the pentester has to achieve multiple objectives, or they disagree on the severity of the findings, both the CISO and the pentester have to agree on both sides of the engagement. We discuss numerous aspects of voluntary pwnage: the differences between a security as..

https://www.defcon.org/defcon-19/dc-19-presentations/Thieme/DEFCON-19-Thieme-Staring-into-the-Abyss-WP.pdf Nothing is harder to see than things we believe so deeply we don't even see them. This is certainly true in the "security space," in which our narratives are self-referential, bounded by mutual self-interest, and characterized by a heavy dose of group-think. That narrative serves as insulation to filter out the most critical truth....
Lock manufacturers continue to produce insecure designs in both mechanical and electro-mechanical locks. While these devices are designed to provide secure access control to commercial and government facilities, in fact many do not. Recent disclosures with regard to extremely popular push-button locks have led to an expanded investigation into their technology and security by our research team. As a consequence, it appears that mechanical l....

https://www.defcon.org/html/links/dc-archives/dc-19-archive.html The only thing worse than no security is a false sense of security. And though we know, "you can't win by defense alone", our modern approaches tend to act as though offense and defense are two entirely separate things. Treating security as an issue of quality has gotten us far, however, nearly everyday, some of the largest companies are still being compromised. It's beco....
At Defcon 17 when a speaker didn't show a bottle of vodka was offered to whoever gave an impromptu talk. Somebody went up and talked about his robot project. He mentioned that it didn't normally drive straight, and talked about all the software solutions he had tried to fix this. I was reasonably intoxicated and wound up shouting at him over the crowd that it did not drive straight because of his drive base design, and not his software. Thi....
There is a long tradition of researchers presenting at security conferences on topics that are embarrassing to a large company or government agency: ATM hacking, router vulnerabilities, Massachusetts toll road RFIDs, etc. Many of these brave researchers risk lawsuits or career ruin to reveal the truth. THIS is the first talk that puts the presenters' very lives in peril. Much has been made of the so-called "IPv4 address exhaustion" problem,....
