2026-09-01 (Target Identification & Attachment Succeeded: PPSA02664 Injected, Hijacking Fix) (D302)

Analyzed hardware test logs (reports/hardware/injector-klog.txt lines 1-116):

  1. Historic Milestone - Full Retail Game Injection Succeeded:
    • MATCHED RETAIL GAME BY TITLE ID: PPSA02664
    • path: /app0/eboot.bin, pid=297
    • PT_ATTACH ret=0, wait4 stop signal=17 -> ptrace attach 100% success!
    • Remote mmap allocated 0x6a0000 bytes at 0x21e540000 via remote syscall 477.
    • All 4 ELF segments mapped and protected with remote mprotect (sysno 74).
    • Entire 9.3 MB payload mapped into the retail game memory!
    • Remote mmap allocated payload args at 0x210034000!
  2. Analysis of Thread Hijacking Glitch:
    • At line 235 of src/injector/injector.c, a redundant second call to krw_elevate_process(target_pid) was executed immediately before hijacking the thread.
    • krw_elevate_process() indiscriminately cleared P_TRACED (0x800) and P_STOPPED_TRACE (0x40000) from the target's p_flag.
    • Stripping P_TRACED during an active ptrace session broke the debugger attachment, causing procctl_setlong (errno 57) and procctl_setregs (errno 1 EPERM) to fail.
  3. Remediation:
    • Remove Redundant Elevation (src/injector/injector.c): Removed krw_elevate_process(target_pid) at line 235 (credentials are already elevated at step 4 prior to attach).
    • Preserve Active Ptrace State (src/injector/krw.c): Guarded P_TRACED and stopped flags in krw_elevate_process(), ensuring that if p_flag & 0x800 is active, the ptrace attachment flags are strictly preserved.

Verified: make payload injector HARDWARE=1 (9,410,856 bytes) compiles 100% clean with zero warnings and zero errors.
