Some things I have done:
- Run the malware itself alone and the malware executes
- Try using other file formats like .doc and the document seems to run fine.
I think the problem I am facing is that for some reason, after the monitor is injected into the process (AcroRD32.exe), the PDF process terminates immediately which I think is the cause of the problem but I am not sure why is it being terminated.
I have use process monitor and verified that both the injector executable as well as AcroRD32.exe is definitely being executed but it seems to terminate prematurely before any analysis could be done.
