Replying to @PlaidCTF
@PlaidCTF, @theori_io (The Duck), and @maplebaconctf are joining forces to play DEFCON as Maple Mallard Magistrates. Some PPP members also play on The Duck & Maple Bacon, so this allows all of us to keep playing on the same team. See you all at DEFCON finals!

😀 I am starting a fundraise for @picoctf. PicoCTF is free to everyone, and costs about $500k a year (🙀) to run. If you've had a positive experience with pico, please reply or DM. I'll use it in my fundraise pitch. Pls RT for awareness. #ctf #hacking

The exploit for Safari is quite complex and massive. I really wanted to understand exactly what the vulnerability was and how it was mitigated, so I dived into the world of browser exploits for a few days and tried to explain how leaking object addresses was possible.

New: In August Google caught hackers using an old Mac exploit together with a zero-day that was published by a research group at a Chinese cybersecurity conference in April. The hackers were targeting Hong Kong users. vice.com/en/article/93bw8y/g…
