Fresh hot PagedOut issue! As usual, I have written an article, this time about using some maths for obfuscation. This is the concept that was the basis for my Google CTF 2024 challenge, "Not Obfuscated". Check it out together with all the other great articles!

Really happy to see this. My @REverseConf talk on reverse engineering Age of Empires inspired some research which led to an RCE vulnerability. Great work, Rick!

Finally, two huge shout-outs for the RE work: • @ZetaTwo for the excellent RE//verse talk • The intern who released AoE2DE_s_original.exe without obfuscation ;) The bug was patched in April (update 174992); MSRC just took a while to assign the CVE.

I'm optimistic we can create _some_ type of knowledge-based security-related community activity but traditional online jeopardy-style CTF as a competitive format is on its deathbed and this video hurts. Big love to the community that has meant the world to me the past 11 years!
