Bypassing Security Hooks

Security hooks are mechanisms implemented by application security products to intercept and monitor sensitive operations within the application runtime environment. In the Deepening Control phase of an attack, adversaries attempt to bypass these security hooks to disable or evade runtime protection services. This sub-technique involves identifying and circumventing function hooks placed in memory, API hooking mechanisms, or callback registrations that security products use to monitor application behavior. Attackers may employ techniques such as direct syscall invocation to bypass user-mode API hooks, memory manipulation to restore original function prologues, or utilizing alternative code paths that avoid hooked functions altogether. By successfully bypassing these security hooks, attackers can execute malicious operations without triggering security alerts, disable monitoring capabilities, and gain deeper control over the application while remaining undetected by runtime protection mechanisms.
