True OG hacker spirit here.

Reverse engineering something just for the sake of undestanding how it works.

No bounty, no cyberz, no monetization, just ask yourself "WTF?" and let your curiosity drive.

This and the previous one it references are fun reads.

@malwaretech minor quip about your long post. MLAT requests are not necesarilly handled by local law enforcement, they may be handled by the judiciary of the receiving country or any other government organization designated in the agreement. This may or may not be an important distinction depending on whether the receiving country's agency automatically coperates with the requestor or imposes more strict criteria to do so.
Dunno the particulars about Switzerland.

So i wrote this on the other site (the short messages wannabe porn site) and predictably got just a single response.
Perhaps here I would fare better?

Reading the Qualys writeup about the OpenSSH race condition RCE it occurred to me that there should be a book titled "Beautiful Exploits" in which a handful of beautiful exploits are explained and their philosophical and historical implications are discussed.

Which ones you'd pick?

A new binary diffing tool was just released.
Its open source, its customizable, and gives the user full control of the diffing process to experiment with.
🔥 Great work by my colleagues at Quarkslab

A good deconstruction of the diffing process and many more details, including diffing of human vs mouse, in this blog post
