HallWatch

HallWatch Copyright C 2026 Adam Zypherion — licensed under GPL-3.0. Indirect syscalls are simple once you have seen one. The loader walks ntdll, reads the SSN out of Nt prologue, finds the 0F 05 two bytes further in, sets r10/rax/rdx/r8/r9 itself, and jmps straight at those two bytes. The syscall...

Hunt-Weird-Syscalls

Hunt-Weird-Syscalls This is a ETW based POC to monitor for abnormal syscalls. For now, the syscalls NtOpenThread and NtSetContextThread are monitored to identify IOCs indicating both direct and indirect syscalls. Description This project uses ETW, more precisely kernel based ETW providers, to...

HellHall

HellsHall - Another Way To Fetch Clean Syscalls HellsHall is a combination of HellsGate and indirect syscalls. How it works First, HellsHall checks whether the syscall address is hooked and tries to retrieve the syscall number by checking the presence of the following bytes: 0x4C, 0x8B, 0xD1, 0xB...
