Dynamic binary instrumentation (DBI) with Dynamo Rio

Summary: Cisco Talos published a tutorial on using DynamoRIO, an open-source dynamic binary instrumentation framework first developed by HP and MIT around 2000, to analyze malware at runtime. The post explains how DynamoRIO operates as a user-space process virtual machine that copies basic blocks into a code cache and extends it with a trace cache, and it compares DynamoRIO against Intel PIN and Frida on overhead, transparency, and platform support.

Bottom line: Talos says it chose DynamoRIO for Windows and Linux malware analysis because of its low execution-time performance impact and transparency, noting that most malware today does not try to detect DBI at all - which means the anti-analysis techniques your detection stack assumes are present may not be the ones adversaries actually deploy.
