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...

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...

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...

CVE-2001-1347
CVE-2001-1347 affects Windows 2000. The vulnerability arises when a local user sets a hardware breakpoint that is handled via global debug registers, which can cause other processes to terminate due to an exception and may allow hijacking of resources such as named pipes. The available sources de...
