' Generic Shellcode Logger v0.1 BETA
' Author David Zimmer <david@idefense.com, dzzie@yahoo.com>
' Uses the GPL Asm/Dsm Engines from OllyDbg (C) 2001 Oleh Yuschuk
'
' Usage: sclog file [/addbpx /redir /nonet /nofilt /dump /step /anydll /nohex]
'
' file shellcode file to execute and log
' /addbpx Adds a breakpoint to beginning of shellcode buffer
' /redir Changes IP specified in Connect() to localhost
' /nonet no safety net - if set we dont block any dangerous apis
' /nofilt no api filtering - show all hook messages
' /dump dump (probably decoded) shellcode at first api call
' /step ask user before each hooked api to continue
' /anydll Do not halt on unknown dlls
' /nohex Do not display hexdumps
'
'Note that many interesting apis are logged, but not all.
'Shellcode is allowed to run within a minimal sandbox..
'and only known safe (hooked) dlls are allowed to load
'
'It is advised to only run this in VM enviroments as not
'all paths are blocked that could lead to system subversion.
'As it runs, API hooks will be used to log actions skipping
'many dangerous functions.
