| | | | | [AI summary] The article discusses the use of Intel Processor Trace (PT) technology to capture code traces from the System Management Mode (SMM) in a computer's BIOS. The authors detail the process of creating a backdoor to access SMM, modifying the SMI dispatcher to redirect execution to a custom shellcode, and using tools like WinIPT and ptxed to analyze the trace data. They also mention challenges such as synchronization issues and the need for cross-platform compatibility, and conclude that this method provides an efficient way to investigate SMM code for vulnerabilities. | |
