FreeRTOS skill for embedded RTOS development. Use when creating tasks, managing priorities, using queues and mutexes, detecting stack overflows, configuring FreeRTOS via FreeRTOSConfig.h, or debugging FreeRTOS applications with OpenOCD and GDB. Activates on queries about FreeRTOS tasks, queues, semaphores, mutexes, configASSERT, stack overflow, vTaskDelay, or FreeRTOS-aware debugging.
End-to-end engineering approach from reverse engineering to working exploit. Applicable scenarios: You have obtained the binary, vulnerability point, and target environment, and need to write a stable exploit (not a script that only works locally but crashes immediately when used remotely). Covers three major areas: stack overflow / heap exploitation / kernel pwn. Emphasizes the engineering gap between "CTF local success → stable remote execution in real scenarios": libc version mismatch, heap spray timing, SMEP/SMAP/KASLR, stack alignment, remote buffering. Core toolchain: pwntools + GEF/pwndbg + ROPgadget/Ropper + one_gadget + libc-database + qemu-system kernel debugging. Trigger keywords: pwn, stack overflow, heap overflow, ROP, ret2libc, ret2csu, one_gadget, libc-database, heap exploitation, tcache, fastbin, unsorted bin, kernel pwn, kROP, SMEP, SMAP, KASLR, modprobe_path, pwntools, GEF, pwndbg.
