w00w00 improved version of depends.exe (minus the GUI + automated searching)

This will find *.exe, *.dll, *.sys, and *.pyd (Python DLLs) that imports a certain DLL or function in a DLL (e.g., import wsock32.dll or import msvcrt.dll!_snprintf) or export a certain function. It can be useful when you don't know what libraries export a certain function (like RtlInitUnicodeString) or you want to find all applications using a function in a DLL with a known vulnerability.

Usage: w00depends test.dll c:\dir\test.exe

Report if c:\dir\test.exe imports test.dll

Examples:

w00depends test.dll!funcname c:\dir\test.exe

Report if c:\dir\test.exe imports test.dll!funcname

w00depends test.dll c:\dir

Find executables importing test.dll in c:\dir

w00depends test.dll!funcname c:\dir

Find executables importing funcname from test.dll in c:\dir

w00depends test!funcname c:\dir

Find executables importing funcname from test.dll in c:\dir

w00depends test!ord_1234 c:\dir

Find executables importing ordinal 1234 (in decimal) from test.dll in c:\dir

w00depends -e funcname c:\dir

Find all DLLs exporting funcname in c:\dir

Output will look like this:
