Cybersecurity firm VulnCheck says more than 20 Zbtlink router models sold under the Zbtlink and Wiflyer brands contain a previously unreported backdoor called Endlessdoors. Researchers say the routers contact a specific IP address and a China-registered domain every 35 seconds. Control of those domains could allow remote access to the routers and other devices on their networks.
VulnCheck estimates that at least 100,000 routers are deployed worldwide, but says their exact locations and active numbers are unknown. Zbtlink did not respond to requests for comment. Researchers and Reuters could not establish the backdoor’s purpose or whether it has been exploited. Beijing denies supporting cyberattacks.
The report warrants attention because routers can expose several connected devices. However, it does not establish who created the backdoor, why it exists, or whether it has caused harm. Claims that all Chinese-made equipment is state-backed should be treated cautiously. Regulators and users should focus on verified technical risks while recognising that the intent and impact remain uncertain.
