Strings (3 patterns)
| Identifier | Type | Value | Modifiers |
|---|---|---|---|
| $s1 | text | "quarks-pwdump.exe" | |
| $s2 | text | "--------------------------------------------- BEGIN DUMP --------------------------------------------" | |
| $s3 | text | "%s_hist%d:\"\":\"\":%s:%s" |
Condition
( uint32be( 0 ) == 0x7f454c46 or uint16be( 0 ) == 0x4d5a ) and filesize < 1MB and all 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 1MB (a cheap guard that skips large files).
- All patterns in the rule must match.
