Anil started a blog in 2004/5 under the name Wng_z3r0 which i used to visit from time to time - http://spyware-free.us - This is what it used to look like - http://web.archive.org/web/200707010742 ... re-free.us - can't seem to load the Rootkit page though - http://spyware-free.us/labels/rootkit.html - via - http://web.archive.org ?

Yesterday i was looking through my old internet favourites to clear out for non working links etc. I found his site has now moved to - http://wngz3r0.info

He has written a small Keylogger with source - http://wngz3r0.info/2010/07/keyloggers- ... l-to-write - that as expected is either undetected/unknown by the vendors, and i imagine lots of other people too.

Result: 0 /42 (0.0%) - http://www.virustotal.com/file-scan/rep ... 1282393199 - This file has never been reviewed by any VT Community member. Be the first one to comment on it!

and Prevx won't allow it to work, as tested on HTTPS and HTTP www's.

It does work on text in documents/notepad etc. One thing i discovered with it is, it misrepresents a handful of lesser used characters for others ? Regular ones like numbers and letters and many others are fine though !

I'm not saying it's a brilliant KL as obviously it has it's faults, just found it interesting that up until now. it's slipped through the net. In it's present state it can't be hidden, so not really much of a threat, but it could still be used to trick etc "some" people no doubt.

Actually it is simple demo of trivial SetWindowHookEx function. I did the same thing nine years ago. There are nothing undetectable in such stuff.
It can't be taken seriously. Thread moved to General Discussion.

@ EP_X0FF

Hi, by undetected i meant by ALL vendors, not actually undetectable per se ;)
I did the same thing nine years ago.
Only nine :P

What's the point to vendors detect sample application? They must then detect sample applications from Jeffrey Richter book chapter related to code injection and a lot of other books.

Thanks for taking note in my little demo. (sorry about the delayed post I just noticed this thread)

The interesting thing is that the injection works with standard user permissions, and the fact that it's trivial to create. What I'm curious about is how you could detect such a hook. I had messed around with the detours API but couldn't get anything to work properly.

As EP_X0FF noted, the actual code sample isn't really interesting. It's just a POC using a standard win32 api.

Your hook will be detected as WH_KEYBOARD_LL with full path to hooker dll.

This detection feature implemented in several antirootkits including RkU.
