Universal Process Privilage Escalation

By adjusting process token its possible to elevate your current process privileges to enable certain functionality not available otherwise.

Basically steps we follow are :
1) Get current process handle
2) Get current process token
3) Resolve SeDebugPrivilege value
4) Created new Token with the resolved value from step 3
5) Adjust the token of the current process with new privilege
6) Close process handle

Following code demonstrates the principle.

print "[+] contact : If you know me then give me a shout"

PID Enumeration on Windows with pure python ctypes

Following code will enumerate process ID’s on the current system by calling EnumProcesses from psapi on Windows. Should for for majority of windows distributions that have psapi.dll in %systemroot%.

from ctypes import *

psapi = windll.psapi

print "[+] PID dumper by Y"
print "[+] contact : If you know me then give me a shout"

def getListOfProcesses():
    max_array = c_ulong * 4096 # define long array to capture all the processes
    pProcessIds = max_array() # array to store the list of processes
    pBytesReturned = c_ulong() # the number of bytes returned in the array
    #EnumProcess 
    psapi.EnumProcesses(byref(pProcessIds),
                        sizeof(pProcessIds),
                        byref(pBytesReturned))
 
    # get the number of returned processes
    nReturned = pBytesReturned.value/sizeof(c_ulong())
    pidProcessArray = [i for i in pProcessIds][:nReturned]
    for processes in pidProcessArray:
        print "[+] Running Process PID %d" % processes
