Some thoughts about Anthropic’s new cryptanalysis results

Yesterday Anthropic published two new cryptanalysis results, both outputs of Claude Mythos, their (still) unreleased advanced model. The first of these results attacks a signature scheme called HAWK, while the second is an improved attack against reduced-round AES. Anthropic also released a blog post describing the research process that produced these results. A few people … Continue reading Some thoughts about Anthropic’s new cryptanalysis results →

I know I am in #DefCon mode because I want to drink Red Bull non-stop. I don't drink it any other time, so it's kinda a strange stress response.

Great new feature in the latest Signal app. If you enable disappearing messages the meta data of calls and missed calls gets deleted as well. I know this was a long standing goal for them, but the engineering behind it took time. #Privacy @signalapp

The safety of our community is our highest priority. For this reason, we have decided to postpone DEF CON Middle East. The evolving security situation in the region makes it impossible to concentrate on delivering the experience attendees deserve. We […] [Original post on defcon.social]

Question about #RainbowTable and #PasswordCracking What is the preferred format today? RT2, RTC, RT (RT1?) and with what tools, rcrack? I'd like to convert all the https://infocon.org/ rainbow tables into whatever the best format is so everyone that downloads them doesn't have to keep […]

I was just moving a server that will be used for the on-site #DefCon 34 content, and one of the redundant power supplies were not snapped into place... slid out right on to the floor. Not to worry, I fixed it by hitting it with my wallet and $175+shipping. 🤦

I’d like to thank @noid for unearthing this ancient picture of me at a hacker space in LA from like 1994 or something:

I was hanging out at a local #Seattle bar I haven’t been to in years yesterday watching USA lose their soccer match. I was served by Antifa and read this great announcement on the wall. Seattle keeping it real.

Onion ads are killing it rn
