Strings (4 patterns)
| Identifier | Type | Value | Modifiers |
|---|---|---|---|
| $ | text | "nirsoft.net" | wide |
| $ | text | "Another logged-in user" | wide |
| $ | text | "Choose config file to save" | wide |
| $ | text | "AdvancedRun" | ascii wide |
Condition
uint16be( 0 ) == 0x4d5a and all of them and filesize < 1MBIn plain words (Heuristic)
- The file must start with “MZ” — a Windows executable (PE).
- The file must be smaller than 1MB (a cheap guard that skips large files).
- All patterns in the rule must match.
