🔹 Bluejacking is the act of sending unsolicited messages to nearby Bluetooth-enabled devices. It’s usually done for fun or pranks—like sending a message that says “You’ve been bluejacked!” to a stranger’s phone. It doesn’t involve accessing or stealing any data. The victim sees the message, but nothing is compromised.
🔹 Bluesnarfing, on the other hand, is a serious security breach. It involves exploiting vulnerabilities in Bluetooth to secretly access data from another device—like contacts, messages, calendar entries, or even files. The victim typically has no idea it’s happening. This is illegal and considered a form of cyberattack.
🧠Quick memory tip:
- Bluejacking = hijack attention (just messages)
- Bluesnarfing = snarf secrets (steals data)
If you're studying Bluetooth attack vectors for pentesting or defense, Bluesnarfing is the one to analyze deeply—it involves protocol-level exploitation and can be mitigated with secure pairing, updated firmware, and disabling Bluetooth when not in use.
