RedMike Hack: Exploiting Cisco Devices for Cyber Espionage
RedMike, a Chinese state-sponsored hacking group known as Salt Typhoon, exploited vulnerabilities in over 1,000 unpatched Cisco devices globally. They targeted telecommunications providers and universities to intercept communications and potentially disrupt critical infrastructure. The attackers utilized CVE-2023-20198 and CVE-2023-20273 to gain administrative access and establish covert communication channels via GRE tunnels. Mitigation involves patching systems, limiting web UI exposure, and monitoring for anomalous activity. The U.S. Treasury Department sanctioned a Chinese contractor linked to these activities, underscoring the international response to state-sponsored cyber threats. Proactive cybersecurity measures, such as those offered by Technijian, are crucial for defending against similar attacks.
