| Explanation | a non-PHP data file (`.dat`/`.gzs`/`.bin`/etc.) contains PHP source — either stored raw under a misleading extension or sealed behind base64/gzip — and/or matches a catalog IOC once decoded. This is the payload-hiding evasion the siteguarding burner fleet used to defeat PHP-only IOC greps: `wp-plugin-management`/`plugin.dat` (gzip+base64 → siteguarding_tools.php v1.7), `speedup-optimization`/`classes/tools.gzs` (base64 → v2.1), `bytedefense`/`core/scan_sigs_db.dat` (raw PHP disguised as a "scan signatures database", `include`d by a web-reachable `scan.php`). The scanner now decodes these blobs and matches PHP markers + content IOCs inside them. |
