Elias watched the sandbox logs. Without the hooks to stop it, the malware began injecting a ransomware payload into a legitimate system process. To the EDR, the system calls now looked perfectly normal because the "interceptor" had been erased. The Lesson
: It read the clean, un-hooked code from the disk into a new section of memory. UnhookingNtdll_disk.exe
Elias realized that UnhookingNtdll_disk.exe was designed to break those hooks. The Methodology: Cleaning the DLL Elias watched the sandbox logs
Elias pulled the file into his sandbox. He watched as the malware performed a classic evasion maneuver: UnhookingNtdll_disk.exe
This is a story about a security analyst’s late-night investigation into a suspicious executable that demonstrates the cat-and-mouse game between malware and modern defense mechanisms. The Discovery
