On this week's show we discuss the BIS decision to ditch its car-a-zay plans for Wassenaar regulation, the latest car hacking news and more.
We also check in with Trey Ford in this week's feature slot. Trey was the General Manager of the BlackHat conference, these days he works at Rapid7, and he joins us to talk about the vibe in Vegas at this year's conference.
Packet Pushers forums let you connect, share knowledge, vent, ask questions, and hang out.

Gregory Pickett of Hellfire Security reached out to me last Wednesday about some interesting research he is presenting tomorrow at Black Hat USA. There are two parts to his research: a security bug in Cumulus Linux (that we already patched) and other network operating systems, and a serious design issue with how all network switches are designed and built.
The security bug was the easy part: it is not exploitable in our default configuration, and Gregory politely gave us a heads up well ahead of time, so we put the fix out last Friday to protect customers who have modified their sudoers configuration in a way that exposed them to the vulnerability. You can see the details in our security fix announcement from last Friday. (If you’re interested in being notified about future security fixes in Cumulus Linux, please sign up for our security mailing list.)
The much more serious issue he will present is the exploitability of firmware in all network switches. This same exploitability has been known about in servers, laptops and PCs for years (and in some cases mitigated with technologies like Trusted Platform Modules), but its application to networking devices is new.
This issue means Continue reading
