Hey everyone, oh it feels like forever, it has been more than 1 year since I last posted here. Anyways, coming to the problem...

What I want to do is search for an executable (or any binary file, that doesn't matter) with out using names but by comparing it to the copy of the executable file I have.

For example,

lets say that I have an executable, A.exe and copied it and renamed the copied one to B.exe and placed B.exe to someplace, so what I want to do is search for B.exe using A.exe since they are the same files but with different names.

I'm not asking anyone to write the script for me, I just want to know what to take into consideration and if this is possible on autoit or not, any help will be greatly appreciated.

Thanks in Advance

akfourtyseven,

Not that difficult to do I would hazard. :mellow:

Ther are plenty of recursive file searchers on the forum to enable you to search in subfolders to any depth. A first check might well be for equal file sizes, followed by a comparison of a suitable hash of the file to confirm.

Happy to go into more detail if required. :(

Thanks everyone for your reply, and M23, I need it to search for a specific malware that copies itself to many folders, and your idea is great and specially if I combine it to search for equal file sizes and then check the hash. But the problem is that since most of the infected PCs already have some kind of PE infecting virus, wouldn't it change the hash of the malware if it gets infected with a PE infecter virus?

akfourtyseven,

Rather out of my comfort zone now, but if only the PE is affected why not just take a hash of the rest of the file?

M23, thanks. Your first post helped me to come up with an idea so is there a function to get the hash of a file on Autoit?

Thanks once again.

akfourtyseven,

A quick search produced this.
