By AJ VicensAug 6 (Reuters) - Chinese router maker Zbtlink Electronics said on Thursday it was suspending sales of routers found to contain a backdoor ‌and pulling the affected software from its website while it developed updates ‌to address the issue. Cybersecurity firm VulnCheck identified a backdoor in at least 20 models of routers ​made by Shenzhen-based Zbtlink Electronics, as Reuters first reported on Wednesday. The tool "has never been used for unauthorized access," the company said. Revelations about the backdoor landed amid growing ​Western concerns ​about cybersecurity and risks posed by Chinese-made ​networking equipment.
