Tools by us, for us, to reverse the hell out of it

Our own tools
November 1998
Dear fellow crackers, Fravias and protectors, we need good and powerful tools to reverse the hell out of it, and we need to know how to use them effectively, and we need to know WHICH tools are out there, on this ever-expanding web of ours, where among tons of useless frills you can find some rare gems like this incredibly good south corean disassembler (with source code!). Moreover we need to develop (or caper) our own tools, because most of the ‘tools of the trade’ we use have been made more in order to check and repair buggy programs you already have the source code of than to reverse programs you don’t even know which compiler has been used for 🙂
If you are so deep inside my site, you already know what Fravias use. We use debuggers (like Softice), disassemblers (like IDA and Wdasm32), flow-analyzers (like Smartcheck), port, file, register and API interceptors (like the great sysnternals suite), windows identifyers (like Customizer) and so on and so on… of course, being respectful Fravias, the first approach when developing our own tools is simply to rip all the tricks we need out of the existing tools 🙂
Good wizard +Mammon_ started this fundamental ‘scouting’ work: you’ll be able to read here his first findings. Let’s now continue:

Let’s LIST the existing tools, a difficult enough task
Let’s MASTER the use of those we reckon to be the BEST, a difficult enough task
Let’s study these targets IN THE DEEP and let’s analyse their tricks (in fact let’s completely REVERSE them), a difficult enough task.

We will -in due time- ameliorate and modify the most interesting code solutions we’ll have found in order to produce our own tools, as +RCG showed in his essay about COMSPY 98. There’s no harry: we have all the time of the world and I’m sure that with the contribution of the smartest Fravias of this planet we will succeed.

There should be a couple of differences between “our tools” and the existing ones:
1) our tools will always be free and will be given out to anybody not only with their source code but also with a complete “history” of their development, that you’ll also be able to follow on this site.
2) Our tools will be more ‘target oriented’ (if you know what I mean 🙂 than the existing ones for obvious reasons.

Now let’s see if we can put some deeds where our mouth is… as usual a project like this one will florish and prosper if many will contribute, will pepper out and die if you do not contribute and if you think it’s a smart move just to leech things out, without giving anything in exchange… you’re not doing just that, are you?

Well, NaTzGUL, for one, certainly was no leecher! his “wisdec” is a real beauty!
This is no usual ‘essat’, this is an example of the creativity and of the cleverness of higher crackers! Enjoy!
Here follows a little list of existing interesting tools (all of them fiddling with vdx and APIs) that you would be well advised to reverse/study/investigate (please notice/add/crack all OTHER missing ones):

Filemon, Regmon, VdxMon, by Mark Russinowich, see my filemon1.htm (etc) essays
MemMonitor95 (see Footsteps’ footthun.htm
Tekfct (see my tekles1.htm)
Comspy 98 (see +RCG’s rcg_cmsp.htm)
Numega’s Softice (see the whole project2.htm)
Numega Boundschecker (see Shadows’ shadow1.htm)
Numega’s Smartcheck (see Snatch’s snatch1.htm and my anonma2.htm)
