Another blog post about attacking the Trezor One #Bitcoin wallet with the #PicoGlitcher and #findus: mkesenheimer.github.io/blog/trezor-wa… This time, a fully locked down device is attacked via a double glitching attack.
Glitching the Trezor One crypto wallet with the #PicoGlitcher and #findus: mkesenheimer.github.io/blog/trezor-wa… It's now possible to recover lost #Bitcoin with relatively low effort.
Today, we have published two security advisories by my colleague Florian Holley concerning the IBM TS4500 Tape Library WebUI (CVE-2021-23450 and CVE-2025-36088). You can find more information in the SySS Pentest Blog: syss.de/pentest-blog/s…
Excited to contribute to the content of this year‘s @hardwear_io . Looking forward to Amsterdam! hardwear.io/netherlands-20…
I've also learned last weekend that concerning insecure encrypted USB flash drives I'm a "bug cousin" to @k8em0. And another "bug cousin" has already reached out to me after my talk via email. 😀 Insecure portable storage devices are definitely not only a thing of the past.
Before lunch at @nohatcon: @TheKenMunroShow “All at sea. Thought your OT/IT was complex? Try doing it on a cruise ship.” 🚢 + @matthiasdeeg “Your Security Update is Not Secure Enough — Hacking Portable Storage Devices Again.” 💻 #nohat2025 #cybersecurity
I‘m on my way to @nohatcon - just across the street. 😄 My first day in Bergamo was already great, and I hope that the weekend will also be an awesome experience.
