In the landscape of cybersecurity confrontation, Endpoint Detection and Response (EDR) tools remain a critical line of defense for defenders. They monitor key behaviors such as process creation, thread activity, and registry modifications to detect and block malicious attacks in a timely manner,Last time we discussed process creation and thread notifications in ‘How Does Windows…

In the Windows security field, many developers and security researchers encounter a common issue: the programs they write (even test samples) get blocked by EDR (Endpoint Detection and Response) tools as soon as they launch. Behind this, EDR’s “sharp eyes” don’t come out of nowhere—they rely on a special privilege granted by the Windows system:…

In the field of Windows security offense and defense, Function Hooking is a core technology for EDR (Endpoint Detection and Response) to monitor process behavior and for attackers to bypass protections. To counter modern EDR interception, the first step is to master the operating mechanism of function hooking in user mode. Centered on the framework of “FUNCTION-HOOKING…
