Strings just scans the file you pass it for UNICODE (or ASCII) strings of a default length of 3 or more UNICODE (or ASCII) characters.
if you run strings on a .jpg and one of them says ‘This program cannot be run in DOS mode‘ that’s no JPEG. Malware authors like to make Portable Executables that end in .gif/.jpg/etc to evade human checks.
Examples:
Search one or more files for the presence of a particular string:
strings *.dll | findstr /i TextToSearchFor
Search a jpg file for signs of executable code:
strings sample.jpg | findstr /i /c:"This program cannot be run in DOS mode"
Perfect!!!
