https://www.defcon.org/images/defcon-19/dc-19-presentations/Robinson/DEFCON-19-Robinson-Time.pdf Computer forensic examiners rely heavily on timestamps during investigations. Timeline analysis is a critical technique in determining what happened and when. In 2005, timestomp.exe was released and this gave non-observant investigators a run for their money. Unfortunately, there are some gaps in what timestomp.exe will do. Observant invest....

For the last few years, historian and archivist Jason Scott has been involved with a loose, rogue band of data preservation activists called The Archive Team. As major sites with brand recognition and the work of millions announce short-notice shutdowns of their entire services, including Geocities, Friendster, and Yahoo Video, Archive Team arrives on the scene to duplicate as much as they possibly can for history before all the data is wip....
The Smart Grid brings greater benefits for utilities and customer alike, however these benefits come at a cost from a security perspective. Unlike the over-hyped messages we usually hear from the media, the sky is NOT falling. However, just like any other technology, the systems and devices that make up the Smart Grid will have weaknesses and vulnerabilities. It is important for us to understand these vulnerabilities, how they can be attack....
https://www.defcon.org/images/defcon-19/dc-19-presentations/Shah/DEFCON-19-Shah-Mobile-Moolah.pdf Smartphones are a hot new market for software developers. Millions of potential customers, and a large percentage willing to part with a small sum of money for your latest creation. Even a moderately successful app can help fill your pockets. It's hard to ignore for legitimate developers. It's even harder to ignore for criminals. Thin....
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/images/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 critica....
Lock manufacturers continue to produce insecure designs in both mechanical and electro-mechanical locks.

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,....
