The smart home threat landscape has evolved dramatically in 2026. Mirai and its successors continue to evolve, targeting over 500 different smart device models. Smart camera ransomware is on the rise. Voice assistant hijacking attacks allow attackers to listen in on conversations. Smart lock vulnerabilities allow attackers to unlock doors remotely. Smart TV attacks exploit outdated Android TV builds. The zero-day vulnerability market has created exploits specifically targeting popular IoT devices — some sold for as little as $5,000. Our report includes specific threat indicators, recommended mitigations, and a device-by-device security checklist. Knowledge is the first line of defense.
