Condition
( uint32be( 0 ) == 0x7f454c46 or uint16be( 0 ) == 0x4d5a ) and filesize < 5MB and any of themIn plain words (Heuristic)
- The file must start with “MZ” — a Windows executable (PE).
- The file must start with the ELF header — a Linux/Unix executable.
- The file must be smaller than 5MB (a cheap guard that skips large files).
- At least one pattern in the rule must match.
