The work-from-home (WFH) mandate created a dramatic inverse of corporate networks, which cyber-adversaries immediately started to use to their advantage. This led to the growth of exploit attempts against consumer-grade routers and internet-of-things (IoT) devices. Cybercriminals are looking to establish a beachhead in enterprise networks by exploiting devices that WFH employees might be using to connect to the enterprise network. The presence of vulnerable devices on home networks significantly expands the attack surface for organizations with a large number of remote workers.
