Is there a way/plugin to make Olly act as a non invasive debugger. Non invasive debuggers don't use the Windows Debug API. Instead, they work by only reading and writing to the target's address space. For instance, WinDbg have this noninvasive mode (/pv) and there's a open source (but unfortunately crude) non invasive debugger called Obsidian.
PS: The problem I am trying to solve is the following: I want to debug a program (let's call it Y) that can only be launched by a parent program (let's say X). But X act as a debugger of Y (preventing Olly from attaching to Y). Moreover, X has some anti debugging techniques. Even after putting a breakpoint on
CreateProcessWandDebugActiveProcess(which are AFAIK the only two functions capable of making X debug Y) on X's address space, nothing happens --- ie, they seem to be never called.A non invasive debugger would allow me to debug Y directly.
