This is a good post about how involved it is to rewrite load-bearing functionality in a memory-safe language:

Many Linux malware samples (notably BPFDoor and similar) hide using classic BPF (Berkeley Packet Filter) socket filters. These filters keep the malware dormant until it receives a very specific “magic packet” ,only then does it activate and reveal itself.
Manually reverse-engineering complex BPF programs (often 100–200+ instructions with heavy branching) to figure out the exact trigger packet used to take hours or even days. Cloudflare’s solution turns this into a process that runs in seconds.

The newly observed capabilities demonstrate how BPFdoor has evolved beyond a stealth backdoor into a layered access framework.
The updated variant combines encrypted HTTPS triggers, proxy-aware command delivery, application-layer camouflage techniques, ICMP-based control signals, and kernel-level packet filtering to bypass multiple layers of modern network defenses.
Each technique targets a different security boundary, from TLS inspection at the edge, to IDS detection in transit, and endpoint monitoring on the host, illustrating a deliberate effort to operate across the full defensive stack.

This weekend I made xoflib with my friends Robin Jadoul and @_tritoke.
xoflib is a Python package for the Shake extendable-output functions (XOFs) written using pyO3 bindings to the sha3 Rust crate.

"a + b", this one line of Python code executes thousands of lines of C behind the scenes. My latest article explains what goes on in the CPython runtime to execute this seemingly simple operation. You will learn about:
- Dynamic dispatch implementation in CPython
- What is the abstract object interface in CPython and its role in dynamic dispatch
- What is the PyTypeObject struct and its role in the CPython runtime
- How the various types in CPython implement operators and make them available to the runtime for dynamic dispatch to work.
- And, look inside the implementation of the float type to understand this more concretely.
The article includes 13 annotated code listings from CPython with all the explanations. Check it out: open.techwriters.info/codeco…

You know that thing where you come up with a cool idea but later realize it wasn’t your own, it was just something you remembered? That’s sort of how generative AI works—there’s an interesting paper by Carlini et al where they illustrate this problem: arxiv.org/abs/2301.13188

While it was good that the public was able to access the unredacted documents, journalists who need to protect their sources should watch out for this kind of mistake by using tools like Dangerzone: dangerzone.rocks/

1/4 I am a GP, I am self-taught in trans healthcare. I treated an 11 year old with blockers and a 12 year old with testosterone. This was fully scrutinised by a Medical Practitioners Tribunal and they determined this was good and necessary care. 🧵
Amazing writeup covering so really neat maths, definitely worth a read if you want to learn about elliptic curves!
