A survey of 2,130 Americans has revealed widespread vulnerability to cyber attacks through unsupported smart devices, with 43% unaware their devices might lose software support. The security threat was underscored in December 2023 when U.S. authorities disrupted a Chinese state-sponsored botnet targeting home routers and cameras that had stopped receiving security updates. Cloudflare separately reported a record-breaking DDoS attack in late 2023, primarily originating from compromised smart TVs and set-top boxes.

The survey, conduced by Consumer Reports, found that only 39% of consumers learned about lost software support from manufacturers, with most discovering issues when devices stopped working (40%) or through media reports (15%). Most consumers expect their smart devices to retain functionality after losing software support, particularly for large appliances (70%). However, Consumer Reports' research found only 14% of 21 smart appliance brands specify support timeframes, while an FTC study of 184 devices showed just 11% disclose support duration.
