A report details that numerous ZBT routers, a leading Chinese manufacturer, are sold globally with embedded backdoors. Specifically, the firmware contains multiple vulnerabilities, including a root-level backdoor found in the latest models. These devices, marketed under various brands, are prevalent in numerous countries, making their security a significant concern.
Research indicates that backdoors such as 'EndlessDoors', 'SpeakingStone', and 'DarkLantern' not only allow unauthorized access but can also initiate connections to control domains, facilitating spying and data theft. While ZBT claimed it would address these issues, consumers are advised to replace potentially compromised routers and consider more reputable manufacturers for their network needs.
