French hacker Eloi Vanderbeken discovered the presence of a backdoor in principal models of routers including Netgear, Linksys and Cisco. Both categories of devices have a backdoor that allows an attacker to reset the admin panel password to defaults, the discovery was made by a French engineer that has found the administration password Reset vulnerability in many Netgear and Linksys Routers. Many other hackers have made a similar research after the Elois discovery, consider that these routers are manufactured by Sercomm, this means that many other network devices are backdoored.”]
