| Explanation | plugin instantiates `new mysqli($var['host'], ...)` — a direct MySQL connection bypassing `$wpdb`. Legitimate WordPress plugins always go through `$wpdb` (which already has the connection); a raw `mysqli` connect using parsed wp-config credentials is the credential-harvesting backdoor shape. |
