HWSyscalls
HWSyscalls Main Contributors Description HWSyscalls is a new method to execute indirect syscalls using 3 main components: Hardware breakpoints and Vectored Exception Handler to control the flow of execution. HalosGate is used to find syscall numbers and addresses. Creating a synthetic trampoline ...
LazyHook
Overview LazyHook is a stealthy API hooking framework that bypasses Host Intrusion Prevention Systems HIPS through call stack spoofing. By leveraging CPU-level hardware breakpoints and Vectored Exception Handling, it executes arbitrary code as if it originated from trusted, Microsoft-signed...

VectoredOverloading
VectoredOverloading Vectored Overloading is a local PE injection technique that was first observed in the KidKadi malware. It works by manipulating the load of a legitimate DLL using Hardware Breakpoints HWBP and Vectored Exception Handling VEH to change the DLL section object on-the-fly...

CVE-2026-89923
A flaw was found in KVM s390. A memory leak occurs in the Kernel-based Virtual Machine KVM for s390 architecture when a virtual CPU vCPU is destroyed while hardware breakpoints are still active, as the associated debug data is not properly freed. A local attacker or a malicious guest operating...

CAPEv2 - Malware Configuration And Payload Extraction
CAPE is a malware sandbox. It was derived from Cuckoo with the goal of adding automated malware unpacking and config extraction - hence its name is an acronym: 'Config And Payload Extraction'. Automated unpacking allows classification based on Yara signatures to complement network Suricata and...
kernel: ptrace() incorrect error handling leads to corruption and DoS
An address corruption flaw was discovered in the Linux kernel built with hardware breakpoint CONFIGHAVEHWBREAKPOINT support. While modifying a h/w breakpoint via 'modifyuserhwbreakpoint' routine, an unprivileged user/process could use this flaw to crash the system kernel resulting in DoS OR to...
