LEVERAGING SYSMON TO COMPLEMENT EDR AND ADDRESS EVASION TECHNIQUES

Summary from the TLDR InfoSec newsletter

Attackers can bypass EDR solutions using techniques such as kernel hooking, syscall injections, DLL unhooking, process hollowing, and APC injection to evade detection. Sysmon event IDs 1, 7, 8, 10, 11, and 12 detect these evasion methods by monitoring process creation, DLL loads, thread injection, memory access, file creation, and registry modifications. Combining Sysmon with traditional EDR forms a layered defense, capturing endpoint activities that standard EDRs miss, particularly low-level memory manipulation and kernel-level operations.
