It's a day of mixed emotions as @CyberDiscUK has concluded. It's been an amazing journey, and James Lyne, Simon Vernon, Simon Mcnamee, @Russ_Taylor_, Jason, and the rest of the team have done a great job. The program has changed the course of my life, and I'll be forever grateful.

Recently released a new project "pwninit.py". As the name suggests, it's a pwninit script written in python, with some extra features. I plan to work on more projects in 2024, so stay tuned :) github.com/sasha-999/pwni…

please god let this merge to mainline because it would be so funny

My COR CTF 2024 writeups for format-string and corchat v3: sashactf.gitbook.io/pwn-notes/ctf-…

Just published 2 pages about setcontext and fork_handlers, about how setcontext can be used to gain ROP, and how overwriting fork_handlers can turn fork in a constraintless one_gadget. sashactf.gitbook.io/pwn-notes/pwn/… sashactf.gitbook.io/pwn-notes/pwn/…

And thank you 쇠돌이, couldn’t have done it without you either. See you in the finals!

Offensive exploit devs to vendor security teams when memory safety gets solved (they both lose their jobs)

Recently did diceCTF 2025, here are writeups for pwn/r2uwu2s-resort and pwn/locked-room: sashactf.gitbook.io/pwn-notes/dice…

As if I needed another reason to move away from gitbook...

I started playing CTFs in 2022, and LLMs definitely changed the **competitive** CTF scene a lot, especially since mid-2025. I also started using LLMs in late 2025. Yes, those models did one-shot many challenges, but what's the fun of slopping them? I learned absolutely nothing 🥲
