New WrtHug campaign hijacks thousands of end-of-life ASUS routers

**Operation WrtHug**: A global campaign exploiting multiple command-injection and authentication vulnerabilities in end-of-life ASUS WRT routers has compromised roughly 50,000 devices (identified via a distinctive 100-year self-signed AiCloud TLS certificate), likely to be used as stealth relay/proxy nodes; vendors have released patches but many devices remain unsupported and at risk.
