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.

1. Pause thread midway in exploit races (even โ“ช).
2. Or block entire CPU core. Kernel APCs run at APC_LEVEL (๐Ÿคฏ), so thread scheduling kinda disabled (think priority == โˆž).
3. Or build upon @hasherezade.bsky.social work & generalize #WaitingThreadHijacking โ€” 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.

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

The gist? Just spam NtGetContextThread(tgt).๐Ÿ˜ธ
