AUTOMATIC INJECTION OF WEAK CODE TO ATTRACT OR DISTRACT MALICIOUS ACTORS
This disclosure describes a computer-readable medium storing instructions for detecting malicious activity by monitoring the execution of intentionally weak code paths embedded within executable code. A monitoring system receives a mapping that associates each injected weak path with a unique identifier, then observes the executable during runtime to determine whether any such abnormal path is taken. Because these paths are designed not to execute during normal operation (implemented through inhibited or dead code reachable only under adversarial manipulation) their activation serves as a signal of potential attack behavior. When the monitoring system detects execution of a mapped intentionally weak code path, it generates a notification within a secure environment, enabling rapid identification of suspicious or unauthorized activity. This technique enhances software security by providing a lightweight, observable mechanism for detecting deviations from expected execution flows.
