Compiled BAT to EXE convert to BAT again ?

#1 Post by silent » 25 Mar 2013 10:39

Hi !
I need help, i have a suspicious EXE file that im sure its made in BAT and it contains some suspicious command like DEL :D
I need to somehow get its code, i cant run it to check if its in TEMP folder, because it will probably delete my system files.I tried decompressing it in UPX as i did already with one EXE file, but now it says this one wasnt packed in UPX.Is there some way to get the source code without running it ?

Might be able to look at it in a hex editor.

But how ? I downloaded some XVI32 hex editor, opened the file in it and i can only see hex values, nothing else.

Greetings silent,
Just curious;
1. What is the name of the EXE file?
2. What is the source of the file?
3. How do you know the DEL command is being used?

Ultraedit is payware but it has a trial version and a solid HEX editor.

Best wishes!
