Bluejacking is usually not very harmful, except that bluejacked people generally don't know what has happened, and so may think that their phone is malfunctioning. The actual message itself doesn't deploy any
malware to the software; rather, it is crafted to elicit a response from the user or add a new contact and can be seen as more of a
prank than an attack. These messages can evoke either annoyance or amusement in the recipient. Users typically possess the ability to reject such messages, and this tactic is frequently employed in confined environments such as planes, trains, and buses. However, some forms of
DoS Disruptions are still possible, even in modern devices, by sending unsolicited pairing requests in rapid succession; this becomes disruptive because most systems display a full screen notification for every connection request, interrupting every other activity, especially on less powerful devices. Bluejacking is also confused with
Bluesnarfing, which is the way in which mobile phones are illegally hacked via Bluetooth. ==Companies==
