Strings (2 patterns)
| Identifier | Type | Value | Modifiers |
|---|---|---|---|
| $s1 | text | "go.buildid" | |
| $s2 | text | "github.com/OXDBXKXO/ez-pwnkit" |
Condition
uint32be( 0 ) == 0x7f454c46 and filesize < 5MB and $s1 and #s2 > 5In plain words (Heuristic)
- 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).
- Pattern $s2 must occur > 5 times.
- Pattern $s1 must be present.
