Cryptographers Held an Election. They Can’t Decrypt the Results.

Trying to think of something serious to say about the β€œcryptographers lose the key for the cryptographer election” story and, mostly, hey: I just love that cryptographers are actually using the weird cryptography! www.nytimes.com/2025/11/21/w...

Impressive work from our team today at #Pwn2Own!

Confirmed! The team from @synacktiv.com used a buffer overflow to exploit the Phillips Hue Bridge. Their unique bug earns them $20,000 and 4 Master of Pwn points. #Pwn2Own

Mafia guy 1: He's wearing a wire!
Mafia guy 2: More importantly, with a microphone, and a recording device on it! Those are a lot more alarming than the wire itself, honestly. Way to bury the lede, Vinnie. Just a wire, I ain't worryin' about.

iOS 18.4 - dlsym considered harmful Observations We first observed the bug in a custom iOS application compiled for the arm64e architecture (thus supporting PAC instructions).

In iOS 18.4, Apple introduced a bug in dynamic symbol resolutions for some specific exports. @0xf4b.bsky.social took a long journey down a rabbit hole to understand its root cause.

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.
