BoundHook Attack Exploits Intel Skylake MPX Feature

October 19, 2017


A post-intrusion technique developed by researchers at CyberArk Labs called BoundHooking allows attackers to exploit a feature in all Intel chips introduced since Skylake. The attack technique allows for the execution of code from any process without detection by antivirus software or other security measures, researchers said.

According to CyberArk, a BoundHooking attack exploits the Intel feature called Memory Protection Extension (MPX) to hook function calls that pass between software components. That allows for an adversary to manipulate and spy on a wide range of Windows applications.
