Cybersecurity Firm Discovers Backdoor in Chinese-Made Zbtlink Routers, Raising Security Concerns
A cybersecurity firm, VulnCheck, has identified a significant security vulnerability in routers manufactured by the Chinese company Zbtlink. The firm discovered a backdoor in the firmware of 20 different Zbtlink router models, which automatically communicates with cloud servers in China. This backdoor could potentially allow unauthorized access to devices connected to the router's network. Jacob Baines, the chief technology officer at VulnCheck, explained that once the router is connected to a network, it attempts to reach a server in China that can control the router. This discovery has heightened concerns about the security of Chinese-made routers, echoing fears that have been expressed by cybersecurity experts and lawmakers for years. The state of Texas previously sued TP-Link, another router manufacturer, over similar concerns, although no backdoor like Zbtlink's has been found in TP-Link routers.
