‎Hacktivate: Capture the Flag ‎Crack codes. Break firewalls. Conquer the map. Hacktivate is the ultimate cybersecurity challenge: a world map of 240 missions where every puzzle is built on real cybersecurity techniques hackers us...

Today I'm launching my new app, Hacktivate. It teaches real-world computer science skills through 240 "capture the flag" challenges, and works on iPhone, iPad, and Mac with one purchase. I've poured a ton of love into it, and I'd love to hear what you think 🙌 apps.apple.com/gb/app/hackt...

I used PE-bear for the first time to dump an embedded binary. Its intuitive UI made extraction effortless. Because malware often embeds payloads with the form A in B to evade detection, pulling out the inner binary was crucial for deeper analysis and IoCs hunting.

Finally done with #FlareOn12. What a ride! I am looking forward to read other people’s solutions, especially of those who did the 9th task quickly.

- option of custom parsing exports directory allows to pinpoint even the APIs that the malware author tried to hide by erasing exports table in memory: (github.com/hasherezade/...)

New #TinyTracer (v3.0) is out - with many cool features: github.com/hasherezade/... - check them out!

1. Pause thread midway in exploit races (even ⓪).
2. Or block entire CPU core. Kernel APCs run at APC_LEVEL (🤯), so thread scheduling kinda disabled (think priority == ∞).
3. Or build upon @hasherezade.bsky.social work & generalize #WaitingThreadHijacking — making it, in fact, Waitless.

Screenshot of contextjail.exe running with default arguments. Highlighted: * prisoner thread (latched to CPU1 with priority 15) couldn't run for the entire test duration (30 seconds). * 99 jailer threads (latched to 6/8 processors, CPU2..CPU7) were using 20% of total CPU time. Overlay: pseudo-ASSCII art with prisoner thread and 6 jailer threads (guards), spamming NtGetContextThread to block the prisoner. Source and compiled binary: https://pastebin.com/pBJcGp1y

Heard of #ContextJail?
It's a nasty new technique: puts target thread into ⓪ deadloop, for as long as you can afford. Requires THREAD_GET_CONTEXT right.

The gist? Just spam NtGetContextThread(tgt).😸
Target will be jailed, running nt!PspGetSetContextSpecialApc 🔁.

yes, we catch it, but I cannot speak for others
