Hardware implants were put in Ledger wallets to steal recovery seeds for crypto accounts. Someone used the seeds last week to hijack $100 million from 300 crypto accounts. Ledger was warned last March about implants but did little. There's evidence the stolen seeds were sent to Hong Kong. My story:

Finally releasing some work with Lennert! cfp.recon.cx/recon-2026/t...

cfp.recon.cxFailure Is Not an Option: A Reliable Process to Exploit STM32F2/F4 Microcontrollers Recon 2026The STM32 family of microcontrollers is deployed in billions of embedded systems, making them desirable, high-value targets. In particular, the STM32F2 and STM32F4 series have been heavily scrutinized due to their use in popular cryptocurrency hardware wallets like the KeepKey, Trezor One, and Trezor Model T. Previous research has shown that fault injection can bypass protection mechanisms and enable flash memory extraction. However, those techniques can lead to device corruption or permanent loss of data. In this talk, Joe and Lennert present three years of work refining and extending these attacks into a more repeatable and reliable process for extracting protected flash memory from STM32F2 and STM32F4 devices. They will discuss the practical engineering behind the work, including failures, breakthroughs, and new attack strategies. Using these techniques, they have recovered the cryptocurrency recovery seeds from dozens of customer-owned hardware wallets with a 100% success rate.

Absolute legend :( I'll never forget when Parmaster shared his Tymnet login with me in 1991. I've had it in my k0dez book ever since.

My wife @debdebdeb.bsky.social and I are heartbroken to share the sad news that our old friend @jasonsnitker.bsky.social AKA Parmaster, has passed away.

"And then it happened... a door opened to a world... rushing through the phone line like heroin through an addict's veins, an electronic pulse is sent out, a refuge from the day-to-day incompetencies is sought... a board is found." 40 years on, this still hits me the same way. phrack.org/issues/7/3
