IoT devices often have weak security defaults. Ransomware can lock smart cameras, home automation systems, or connected appliances. Botnets use IoT devices to spread malware. Limited update mechanisms make infection persistent. While less common than PCs, attacks on IoT are rising.
It matters because personal safety and privacy are threatened. Security practices for IoT are lagging.
It also signals a future attack vector as homes and cities get smarter.
Ransomware can infect IoT devices, locking or exploiting them.
