Hey guys,

Well in the past my previous work was shit and didn't work, ha. This is going to stay as the same thread for my new upgrades / updates so that means I won't keep making seperate topics for each new version upgrade. Also, i've learned a lot so i'm at the moment adding an AOB (Array of Bytes) scan and also a Pointer-scanner.

Current Features

your injector is painfully small and does not work. attempted to inject to msn and nothing came up. this does not work either.. perhaps you should test your stuff before releasing. i'm quite sure i've said that to you in the past already..

Ha, it works 'bud, test on my PC and 3 other PC's. Make sure you have the latest redristutable of Visual C++. Also, try to Run As Administator, if nothing happens, I did forgot to add token priviledges.

i have the 2010 redist. you have to run as admin then it makes a window. the GUI looks stupid. idk what you did with the buttons but that was a bad move. i'm guessing sunken style, client edge, etc..

tried scanning for 0 as a byte value with 'fast scan'. scanner freezes up and goes to 'not responding'. waited about a minute, still nothing. this is a pretty fast machine, 8 cores with windows rating of 7.3 for processor + memory.

yep, this is a case of take it back to the garage and try again.

0 takes some time, its actually scanning but there are so many addresses which has 0 bytes. Try scanning for 1, etc. Other then that, I got many addresses from my program, so to me its very useful and isn't considered garbage.

garbage goes in trash can. cars and failed hobbyist projects go in the garage. i'm not gonna test it any further since as far as i'm concerned, if the user can make your program freeze/not respond/crash and you give them no indication that there is some sort of progress going on, then it's a failed project. this includes me giving garbage input and your program not sanitizing it and crashing because of that.

here's a tip. don't do your scanning while handling a windows message. what i suspect you are doing right now is to just handle the wm_command sent by the button then scanning right there. instead call a function which creates a bunch of worker threads which concurrently scan different regions of the memory. to make it even more snazzier, after your scheduler is done allocating worker threads, make it start a progress bar.

I guess your comment goes in the garbage as well Smile

I already do that, and BTW forum, whats faster?

Reading the whole memory region with memcpy() and then comparing each byte or comparing each byte by each address as you go along.

moving to binaries.

yes, you're right. my post is definitely classified as a car or failed hobbyist project. evidently, c++ is not the only language you need to brush up on.

and you clearly don't already do that. ollydbg does not lie. read whole memory region. although it's completely pointless either way since you're using an injected dll, there is no need to copy anything. you can just read it directly from where it is. doesn't matter though. since it's pointless it will keep perfect consistency with the rest of your project.

this does nothing for me either, nothing comes up and it provides no meaningful info as to why.

Hmm trying to add a text-string value scan, but I rarely understood how it works, so we are sopposed to compare each text string size right?

slovach : run as admin it

ipromise : go get your eyes checked out. i already told you which one was faster.

It freezes on small values (0,1,2,3, etc...). But I tested it with some larger, and more arbitrary values, and it seemed to do just fine. I'll agree with Slugsnack though, you may want to fix the buttons.

not necessary. as you were told many times in your other thread you can do a strcmp and the null terminators indicate the end of string.
