I just published a blog post about getaddrinfo and all the other weird DNS APIs that we use in Firefox to resolve HTTPS records.

All this was part of the talk I gave at FOSDEM last weekend.
ROPing our way to “Yay, RCE” - and a lesson in the importance of a good nights sleep!
From vulnerability to exploit - follow our Colleague Michaels journey of developing an ARM ROP chain to exploit a buffer overflow in uc-http
Via Return-Oriented Programming chain small code snippets, or gadgets, already present in a program’s memory can be leveraged
By chaining these gadgets together, they can execute arbitrary code without injecting anything new
Dive into the process of reverse engineering, gadget hunting, and crafting a working exploit.
Learn all about it in Michaels full report.

UK orders Apple to put backdoor in iCloud encryption (Advanced Data Protection, which is end-to-end encrypted):

The way this plays out is that UK iPhones lose the Advanced Data Protection feature, right?
Right??
Big news in Italy around the government misusing Paragon, and Paragon ended up cutting the contract citing misuse/ethical violations.
I commend Paragon on this one, the misuse was pretty blatant and as Italian sad to see. This is how the industry should react to misuse!
****For students and private individuals (not paid by a company) ONLY***
We are releasing a very limited amount of tickets for students and private individuals.
These tickets will be discounted in price and are separate from the waiting list.

Students will have to bring a valid student ID to the conference.
We would love to see submissions from anyone.
Time is running out. Don’t let the ticket to @reverseconf go to waste.
For those who are stuck at the exploitation part, the picture we showed previously and this article will help a bit

My 10k-word writeup on exploiting a heap-overflow in Llama.cpp's RPC Server's Tensor-operation to RCE. This by far is one of the most challenging but fun exploitation I've ever researched on.

I cover cybersecurity and national security, writing about: nation-state hacking, espionage, cyber warfare, cybercrime, and policy. I don't write about companies - unless they've done something wrong.
I keep coming across all these "pseudocode" examples on Wikipedia and in academic papers, and what I don't understand is why the authors can't just learn a real programming language
