At the gpg.fail talk and omg #39c3

You can just put a \0 in the Hash: header and then newlines and inject text in a cleartext message.

Won’t even blame PGP here. C is unsafe at any speed.

gpg has not fixed it yet.

All of them were fixed in the iOS 26.1 (and equivalent) update last month. Definitely some cool bugs in there!

We derestricted crbug.com/382005099 today which might just be my favorite bug of the last few years: bad interaction between WebAudio changing the CPU's handling of floats and V8 not expecting that. See crbug.com/382005099#co... for a PoC exploit. Also affected other browsers

SCOOP: A man who worked on developing hacking and surveillance tools for defense contractor L3Harris Trenchant was notified by Apple that his iPhone was targeted with mercenary spyware.

The developer believes he was targeted after he was wrongly accused of leaking zero-days developed by Trenchant.

Serious bugs often occur in third-party components integrated by other software. Ivan Fratric and I found this vulnerability in the Dolby Unified Decoder. It affects Android, iOS and Windows among other platforms, sometimes 0-click.

"Windows App to replace Remote Desktop app for Windows"

There's a lot of confusion about what this means, so let me clarify:

This only affects the Remote Desktop App on the *Microsoft Store*, which you most likely don't use

Most system administrators use mstsc, the Windows built-in RDP client

We will never know— we will never have the faintest idea— how much money is getting made in insider trading windfalls from people in Trump's and Musk's circles who have an hour of notice about the daily swings in tariff policy or the occasional announced *expectations* of such swings.

Ghidra 11.3 is OUT!


PyGhidra is the new feature to be excited about.

It’s a Python library providing direct access to the Ghidra API. 



I expect this to massively increase Reverse Engineering tool development, as it significantly reduces the barrier to entry for Ghidra interaction.
