Three distinct implants—SPEAKINGSTONE, DARKLANTERN, and ENDLESSDOORS—have been discovered embedded in ZBT router firmware distributed through a global supply chain reaching the United States, Canada, Australia, Philippines, Germany, and Russia. DARKLANTERN is an unauthenticated UDP backdoor listening on port 9992, offering root shell access from the internet with trivial MAC address bypass. SPEAKINGSTONE is a phone-home surveillance implant that beacons to ZBT's cloud infrastructure, capable of DNS hijacking, ISP credential theft, and remote command execution. A sinkholed backup domain revealed 392 devices, 390 located in China, primarily on China Mobile's network. Internet scans identified 203 DARKLANTERN instances across 22 countries. These implants use plaintext protocols without authentication, making them hijackable by any network adversary. The affected hardware appears in white-labeled consumer products sold through mainstream retailers, representing embedded surveillance capabilities in commerciall...

Socket Threat Research team identified 19 malicious browser extensions (18 Chrome, 1 Edge) published in the last six months, delivering an extendable malware framework. These extensions establish WebSocket communication with command and control servers, strip Content Security Policy headers, and use XSS injection to execute malicious payloads. The primary focus is cryptocurrency wallet secret stealing and crypto draining. The threat actor employs two publishing approaches: creating malicious extensions from scratch or acquiring legitimate extensions with established user bases and weaponizing them. The most impactful case involves the 'Enable Right Click & Copy' extension, which had approximately 70,000 Chrome users and 10,000 Edge users when compromised. The campaign, tracked as 'Superior', has been active since February 2024, demonstrating sophisticated operational capabilities and persistent evolution of malicious modules targeting multiple cryptocurrency platforms, exchanges, and credential harvesting.
