I've been experimenting with improving Binary Ninja's analysis of Objective-C code recently. Having the ability to hide Obj-C runtime reference counting calls, and apply type information based on [super init] and objc_alloc_init calls can dramatically improve the readability (and in some cases even accuracy!) of the decompiled code.

One would think the rational cause of CS layoffs (instead of the bullshit AI narrative being pushed) is the shaken customer trust following The Whoopsie, but of course infosec is not a rational economy.

I’m sorry, but Facebook did more harm to humankind than all NSO-alike spyware vendors of the world altogether. You are fighting into the wrong direction

Next Thursday, May 15 at @NorthSec in Montreal, I will be hosting the workshop "Reconstructing Rust Types: A Practical Guide for Reverse Engineers"! This will be a 3-hour workshop how to approach Rust types and data structures when reversing Rust binaries. See https://nsec.io/session/2025-reconstructing-rust-types-a-practical-guide-for-reverse-engineers.html for more details!

Workshops at NorthSec will be streamed on YouTube Live. My workshop is scheduled for 1300-1600 EDT (UTC-4) on Thursday, May 15 in the Workshop 2 track, in Salle de la Commune. The stream link for all the Thursday Salle de la Commune workshops is here: https://www.youtube.com/watch?v=UwJgS32Q6As&list=PLuUtcRxSUZUrW9scJZqhbiuTBwZBJ-Qic&index=7

Looking forward to seeing folks there! 🦀

(Edited since I can't count days of the week apparently: May 15, which is when my workshop is occurring, is a Thursday, not a Wednesday.)

Everyone agrees something needs to be done about our total dependence on US clouds. But what? And who should do it? Ample words have been written on the 'why', and we also have a lot of text on our values and that *someone* should do *something*. Here I elaborate on an earlier suggestion with a coherent strategy that is concrete enough to disagree with. This reads well with the latest Euro-Stack letter also: https://berthub.eu/articles/posts/a-coherent-non-us-cloud-strategy/

This is a gruelling summary of all the things wrong with OpenSSL https://www.haproxy.com/blog/state-of-ssl-stacks I've mostly watched this whole thing from the sidelines, but was also affected noting that private key parsing suddenly became 70 times slower. I think they've now improved it to "only" be 10-20 times slower, and there does not seem any effort to work on it any more.

This was such a relatable blog post, heck.
