VulnCheck found two more factory backdoors in ZBT router firmware: SPEAKINGSTONE and DARKLANTERN (CVE-2026-74232/74233). One calls out, one listens on an open port for anyone to reach as root. No fix. Replace the hardware. https://suriq.io/blog/zbt-speakingstone-darklantern-router-backdoors #CVE #SupplyChain #infosec #cybersecurity
