Python is quick turning into the programming language of selection for hackers, opposite engineers, and software program testers simply because it's effortless to write down speedy, and it has the low-level aid and libraries that make hackers satisfied. yet formerly, there was no genuine handbook on easy methods to use Python for a number of hacking initiatives. You needed to dig via discussion board posts and guy pages, perpetually tweaking your individual code to get every thing operating. no longer anymore.
"Gray Hat Python" explains the techniques at the back of hacking instruments and strategies like debuggers, trojans, fuzzers, and emulators. yet writer Justin Seitz is going past thought, displaying you ways to harness latest Python-based protection instruments - and the way to construct your personal while the pre-built ones won't reduce it.
You'll the way to: Automate tedious reversing and safety initiatives layout and application your individual debugger find out how to fuzz home windows drivers and create strong fuzzers from scratch appreciate code and library injection, gentle and tough hooking ideas, and different software program trickery Sniff safe site visitors out of an encrypted internet browser consultation Use PyDBG, Immunity Debugger, Sulley, IDAPython, PyEMU, and extra
The world's top hackers are utilizing Python to do their handiwork. Shouldn't you?

Once the system determines that we have appropriate rights to access the process, the target process assumes that the attaching process (the debugger) is ready to handle debug events, and it relinquishes control to the debugger. aspx). aspx). Bu il din g a Win do ws D eb ug ger 29 debugger traps these debugging events by calling WaitForDebugEvent()6 in a loop. The function looks like this: BOOL WINAPI WaitForDebugEvent( LPDEBUG_EVENT lpDebugEvent, DWORD dwMilliseconds ); The first parameter is a pointer to the DEBUG_EVENT7 struct; this structure describes a debugging event.
The page permission we are interested in is the guard page. This type of page is quite useful for such things as separating the heap from the stack or ensuring that a portion of memory doesn’t grow beyond an expected boundary. It is also quite useful for halting a process when it hits a particular section of memory. For example, if we are reverse engineering a networked server application, we could set a memory breakpoint on the region of memory where the payload of a packet is stored after it’s received.
34 C ha pt er 3 LONG tpDeltaPri; DWORD dwFlags; }; The three fields in this struct that we are interested in are dwSize, th32ThreadID, and th32OwnerProcessID. The dwSize field must be initialized before making a call to the Thread32First() function, by simply setting it to the size of the struct itself. The th32ThreadID is the TID for the thread we are examining; we can use this identifier as the dwThreadId parameter for the previously discussed OpenThread() function. The th32OwnerProcessID field is the PID that identifies which process the thread is running under.
