Strings (4 patterns)
| Identifier | Type | Value | Modifiers |
|---|---|---|---|
| $ | text | "[.] SMEP & SMAP bypass enabled, turning them off" | |
| $ | text | "[.] done, SMEP & SMAP should be off now" | |
| $ | text | "[.] executing get root payload %p" | |
| $ | text | "[.] done, should be root now" |
Condition
uint32be( 0 ) == 0x7f454c46 and filesize < 1MB and all of themIn plain words (Heuristic)
- 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.
