Mark Manning @antitree.com · 03/08/2026Heading to DEFCON. Couldn't find anyone that made this so I wrote it: A flipper zero NFC canary: keep it in your pocket or bag to keep track and alarm when someone tries to scan your gear while you're walking around the con. github.com/antitree/nfc... 0101
Mark Manning @antitree.com · 04/06/2026Tomorrow is my last day at @chainguard.bsky.social Best company ever. I may kick myself for leaving but I will definitely kick myself if I don't try out the next opportunity. I've been a fan of this company from its inception. Marketing to 4-10 year olds in my neighborhood since 2023 010
Mark Manning @antitree.com · 07/03/2026A quick video of the current home of Rochester 2600. Thanks to Forrest. Not shown here: The earthquake button that simulates what it would be like working for a tech company in San Francisco. 000
Mark Manning @antitree.com · 11/12/2025All the AI in the world and Google's cameras still think snow is someone walking 120
Mark Manning @antitree.com · 26/11/2025I'm a sucker for books that support my belief that we're all doing infosec poorly or just for the sake of infosec. This has been an interesting read so far 030
Mark Manning @antitree.com · 04/10/2025This was 2600 meeting last night. It's getting overwhelming when you look closely 010
Mark Manning @antitree.com · 24/08/2025An answer to everyone's question: "What if a Linux syscall was an anthropomorphic action figure?" 010
Mark Manning @antitree.com · 10/08/2025Nothing beats getting out for a run in Vegas before sphererise. #defcon 040
Mark Manning @antitree.com · 08/08/2025Catching @bouncyhat.bsky.social 's talk in track 4. Pretty excited 010
Mark Manning @antitree.com · 08/06/2025All I can say is I worked very hard to angle myself into a position to receive one of these today. Thanks @bsidesbuffalo.bsky.social 080
Mark Manning @antitree.com · 07/06/2025Just a Friday night with containers, seccomp profiles, and LLMs at @roc2600.bsky.social 000
Mark Manning @antitree.com · 09/05/2025Going back to CVE-2019-5736 for a true container 0day for a demo at @bsidesbuffalo.bsky.social next month. Seccomp will save us right? 011
Mark Manning @antitree.com · 19/04/2025It was a great week at @chainguard.bsky.social when I found out I work with the person that wrote Crane and he pointed me at some fun registry security hints. Here's a preview of an update I'm working on to autodiscover whiteout files in registry images 130
Mark Manning @antitree.com · 19/03/2025Here are my slides from @bsidesreykjavik.com. * Backdooring a container image (Vault) * Exfiltrate secrets via DNS * Update to pillage registry tool (originally created by Josh Makinen) www.canva.com/design/DAGgr... 142
Mark Manning @antitree.com · 19/03/2025Excited to be at @bsidesreykjavik.com. I have some guilt that I am missing my hometown B-Sides ROC for the first time ever though which is also today but I can't resist Iceland. 061
Mark Manning @antitree.com · 18/03/2025As expected, Reykjavik is still pretty cool. My @bsidesreykjavik.com is tomorrow morning bright and early so laying low tonight and appreciating the scenery 020
Mark Manning @antitree.com · 17/03/2025Idk how many people I've shown K9s to now but everyone has the same reaction - what is that and give it to me! I wish I had time to hack in some of the cool Chainguard debugging tools though 010
Mark Manning @antitree.com · 13/01/2025My prize possession. A gift from @neutrino.bsky.social who is adding 3d printing to his list of expertises 170
Mark Manning @antitree.com · 11/01/2025Quick preview of my seccomp tool for containers that I'll be presenting tomorrow at #shmoocon 060
Mark Manning @antitree.com · 13/12/2024Years ago I built this custom magnetic poetry set to come up with future vulnerability names. Anyone interested in a pack? 020
Mark Manning @antitree.com · 12/11/2024I just learned that part of the XZ incident, the attacker disabled Landlock, thE application sandboxing LSM (that I keep hoping grabs more use cases) 1. I didn't think Landlock was that widely adopted at the app level 2. Surprised that XZ could meaningfully use it for such a low level function 010
Mark Manning @antitree.com · 08/11/2024I don't always buy lock picks IRL but when I do, it's from an unmarked warehouse that only accepts cash. 10/10, loved visiting Peterson Manufacturing in Rochester today for a local pickup. 010
