Bluejacking

Bluejacking is a type of wireless networking that uses Bluetooth technology to send short messages to other Bluetooth devices in the area. It was first developed in 2000.

Bluejacking involves sending unsolicited messages from one Bluetooth-enabled device to another. The sender will use their smartphone or tablet to send anonymous messages, often containing a link or advertisement, to other nearby devices that are discoverable. It is possible to send short messages to target multiple devices, but the success rate depends on the proximity of the devices.

In general, bluejacking is used for fun and as a way to leave anonymous messages, rather than maliciously. It is a way to engage with strangers in public and add a bit of harmless mystery to day-to-day life.

However, bluejacking can also be used in malicious ways. It is possible to send malware, links to phishing sites, or other malicious content. Additionally, bluejacked devices can be used by hackers to gain access to networks, spread viruses, and launch denial of service attacks.

Given the potential for misuse, many Bluetooth-enabled devices are shipped with the security feature enabled. This means that discoverable mode must be manually enabled in order for bluejacking to be possible.

In summary, bluejacking is a type of wireless networking that uses Bluetooth technology to send short messages to other devices in the area. It is mainly used for fun and to engage with strangers, but there is potential for misuse.
