Chaining Five Vulnerabilities to Exploit Netgear Nighthawk RAX30 Routers at Pwn2Own Toronto 2022 The Internet of Things (IoT) has become an increasingly popular target for cyber attacks in recent years because these devices are often poorly secured and can be easily compromised. To highlight the vulnerabilities of IoT devices and encourage better security practices from manufacturers, the Zero Day Initiative (ZDI) organized a Pwn2Own competition last fall in Toronto that focused on hacking into IoT devices such as printers, network-attached storage (NAS) devices, routers, and smart speakers.
