So I'm officially on the market looking for my next role.
Honestly I'm looking to help train the next generation, PKI engineering, network engineering, security shenanigans, offensive work, or if you have a password cracking role I'm open.
Still recovering from a phenomenal @vcfmidwestshow by @mikeleemm @Silent700 @MobyGamer and Doug. Thanks to Kahn for letting us hang out at his table and to all of the exhibitors for their amazing set ups! Can't wait to see you all again next year!

For over three years, @LennertWo and I have worked on improving fault injection attacks against STM32F2 and STM32F4 devices to make them more repeatable and reliable. It's been a roller coaster of late nights, bricked chips, and questioning our life choices, resulting in over 100 million total glitches, a new attack strategy, and flash memory recovery from dozens of locked targets with a 100% success rate. I'm super proud of what we've done and happy to officially share it with the world!

🛩️ This is so cool: A Redditor living under SFO's takeoff path built a ceiling projection that maps every plane flying over their house in real time, using ADS-B, the open radio signal aircraft broadcast on 1090 MHz. Same feed as FlightRadar24, picked up with a cheap SDR dongle and beamed onto the ceiling.

Special notes about this one, the person learned to safe crack at the conference and used a speed cracking technique from watching YouTube
And if you're on twitter - would love to see any pics of your bedazzled badges! Would also love to see any write-ups go onto reddit.com/r/Tymkrs/comments…

Just finished off my @CypherCon talk, also special thanks to @OpenAI for banning my account for writing a talk on an expired conference badge, your cyber security protocols are great, an 80 bit speck cypher with normal perl rand is really going to enable ransomware
