MindshaRE: Finding ActiveX Methods Dynamically

Today we step back into the world of COM/ActiveX to dynamically find object methods in a binary. This is probably the quickest way to identify the code handling the javascript/vbscript invocation of methods. This can then allow the researcher to audit the method for any potential vulnerabilities.MindshaRE is our monthly look at some simple reverse engineering tips and tricks. The goal is to keep things small and discuss every day aspects of reversing. You can view previous entries here b ...
