Something about RtlQueryProcessDebugInformation

April 12, 2009

Hi,

Just a precisation, as you can see in the code I used psapi.lib, this is obviously not necessary for the code that I reported here, but can be used to enumerate all processes and by passing their PID to RtlQueryProcessDebugInformation we can inspect if there are debugged running processes It’s important to implement a check for the return value of RtlQueryProcessDebugInformation cause, for some PIDs it fails and we have a non sense DEBUG_BUFFER and a consequent non sense DEBUG_HEAP_INFORMATION. Implement a check for 0xC0000008 and 0xC0000017

See you to the next post.. 🙂
