A three part blog series by @jack_halon provides a great introduction into v8 and JS internals, compilation pipeline and ends with analyzing and exploiting CVE-2018-17463 a JIT vulnerability in Turbofan:

After hours of Flutter AOT reversing, Dart object pool decoding & AES key derivation tracing, I became the first globally to crack DroidPass

Nobody’s cracked this Android lab yet 🤯
Meet DroidPass: Ultimate Password Vault, a purposely flawed password manager hiding its base encryption key inside the APK. Your mission: statically reverse-engineer the app and extract the exact base key used to encrypt the password DB.
Think you can be the first to break it? Drop a comment if you’re in. Winner gets ultimate bragging rights🔥

@idkhiddenwtf nice, cant wait for the write-up

[ReverseThatApp @ReverseThatApp]

Just published my #flareon12 challenge 8 write-up
Spent hours playing with Intel Pin (wrong path 😅), then switched to a bottom-up event-based approach using WinDbg TTD, x64dbg, ret-sync & IDA — felt like cracking old game trial licenses again 😄

@TriggerMeHappy @m_r_tz same approach, it's just annoying scrolling up and down :D

[ReverseThatApp @ReverseThatApp]

@m_r_tz why? whyyyy? 😂

@8kSec submitted last week, could you please check the solution and attached write up?

[ReverseThatApp @ReverseThatApp]

@8kSec challenge solved, drafting the write ups 😁

@malware_owl congrats 🔥

When static analysis hits a wall, dynamic tracing with Frida’s Stalker API reveals what’s really happening at runtime.
Learn to trace ARM instructions, filter for ldr/str, and see how obfuscated apps manipulate data:

Tried out Harmony for the first time. It’s super handy for reverse engineering obfuscated C# binaries, especially when it comes to automation. I used to struggle automating steps in dnSpy, but Harmony made it seamless. Checkout my writeup on Securinets CTF https://t.co/uJHGd4iBtg

@zvikam now we understand what is sm in the challenge name stands for 😆

@TriggerMeHappy @Mandiant must be this year is easier 😅

[ReverseThatApp @ReverseThatApp]

Really enjoyed #flareon12 — especially challenges 7, 8, and the brutal but fun final challenge (9). 🧠🔥
Thanks to @Mandiant for another amazing RE CTF.
