Anti-Debugging Bypass
SkillDev toolsLets your agent detect and bypass anti-debugging techniques like ptrace checks and timing tests.
Instructions available. Your AI can read the instructions. Execution depends on the setup they require.
Account requirements not reviewed. Check the skill instructions before use; ahel provides instructions and does not run this skill.
Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.
Then ask your AI: use the Anti-Debugging Bypass skill

Detection Patterns
Linux
- ptrace(PTRACE_TRACEME) — if fails, debugger attached
- /proc/self/status → TracerPid field
- LD_PRELOAD hook detection
- Timing checks: rdtsc before/after operations
Windows
- IsDebuggerPresent() / CheckRemoteDebuggerPresent()
- NtQueryInformationProcess(ProcessDebugPort)
- NtGlobalFlag in PEB
- CloseHandle with invalid handle → exception if debugged
- Timing: QueryPerformanceCounter / rdtsc
macOS
- ptrace(PT_DENY_ATTACH)
- sysctl kinfo_proc → p_flag & P_TRACED
- task_info(TASK_FLAGS_INFO)
Bypass Techniques
- LD_PRELOAD hook to intercept ptrace/IsDebuggerPresent
- Patch PEB directly (NtGlobalFlag = 0, BeingDebugged = 0)
- Frida hook: Interceptor.attach to return false
- SMC (Self-Modifying Code) to hide breakpoints
- Nanomites/timing: normalize rdtsc deltas
- TLS callback to run before debugger init
Execution
When triggered by "anti debug" or "debugger bypass":
- Identify target platform and anti-debug technique used
- Generate platform-specific bypass code
- Verify bypass works
- Write patched binary / hook script to disk
