Bluejacking refers to sending unsolicited messages over Bluetooth to nearby devices.

• A. Hacking into a router's admin panel
• B. Intercepting emails
• C. Sending unsolicited messages over Bluetooth to nearby devices
• D. Scanning for open Wi-Fi networks

Answer: (C)

Bluejacking involves sending unsolicited messages to nearby devices over Bluetooth, often using the device’s discoverable mode to deliver a message or contact card without requiring pairing. The idea is limited to proximity-based Bluetooth data transfer, typically as a playful or nuisance message rather than a true breach of data. This differs from hacking into a router’s admin panel, intercepting emails, or scanning for open Wi‑Fi networks, which involve different technologies and targets. To reduce risk, keep Bluetooth off when not in use or set devices to non-discoverable, and apply security updates as needed.
