IoT Attacks Increase by Orders of Magnitude, But Routers Might Still be Key

By 2025, there will be 41.6 billion connected internet of things devices, generating 79 zettabytes (ZB) of data, according to IDC. That is the sort of forecast that five years ago might have been ridiculed as excessively optimistic. Indeed, some forecasts suggest that could be high by an order of magnitude.

All represent attack surfaces. About 98 percent of all IoT traffic is not encrypted, perhaps driving an increase in attacks of perhaps two orders of magnitude in the first half of 2019 alone. 

Some studies suggest the average IoT device was attacked once every two minutes at times of peak activity. But routers are the target of up to 75 percent of attacks, Symantec data suggests.
