Abstract
Disclosed is a system and method for setting breakpoints (BPs) that cannot be detected by code being debugged, e.g., to trap transparently at any instruction. The disclosed system and method permits execution tracing and instrumentation of binaries, including malware. The system and method can be used to analyze benign software also, e.g., software obfuscated for anti-reverse-engineering. An invisible breakpoint (IBP) is not detectable by the 'guest,' the program being debugged. Hardware virtualization is used to split the code and data views of the program's text segment(s).
