Cryspen's Approach to TLS: A Critical Analysis An examination of Cryspen's TLS implementations reveals 75% of valid ECDSA signatures rejected, authentication tags silently dropped, no certificate validation, and remote denial-of-service vectors.

NEW: Additional critical vulnerabilities in Cryspen "formally verified" code, this time in their TLS stack.

Read our full disclosure, including an update on how Cryspen has handled our work so far: symbolic.software/blog/2026-03...

the streets. We are caught in between monsters; between a ruthless enemy that wants to impose his conditions & an Iranian proxy that has no regard to lebaneese life. Everything for the future seems bleak.

Walking the streets of Taipei! So interesting! What an alive and unique city. The people are expressive and seem happy.

After being awake for 25 hours straight (of which 13 were spent on a plane and 6 aimlessly roaming Taipei until my hotel check-in time was reached) I can now go to bed, which is a fantastic development and great news. Here are photos taken of Taipei during my sleep deprived exploration of the city.

After 13 hour direct flight, arrived at hotel at 9am only to discover that I can’t check in until 4pm, meaning that Taipei must now contain me, already sleep deprived, and progressively getting more and more sleep deprived for the next seven hours

I’m so impressed with how great the Nintendo Switch 2 port of the new @residentevil.capcomusa.com game looks. Unbelievable graphics especially for a handheld, and such engrossing gameplay! I’ll be able to enjoy it on my flight to Taipei without feeling like I’m missing out for not playing it on PC.

How to even proceed? So many findings at this point that you lose consideration for the people writing the code based on how they treated you for reporting your earlier findings, and it's no longer fun or interesting, but more so disgusting, like when you're forced to use the WC at the mall.

I have been venting my (highly considerable) anger at the war returning in Lebanon by performing further auditing of Cryspen's code, and I'm sorry to say that I am up to 14 new, previously unreported vulnerabilities, of which five are at least high in severity (probably critical).
