Difficulty: EasyNetwork and Wireless Attack Indicators

An employee working in a public conference hall receives several unsolicited contact cards and pop-up text messages on their smartphone via Bluetooth. A subsequent investigation by an IT technician confirms that no files, credentials, or personal data were stolen or accessed from the device. Which of the following wireless attack indicators is described in this scenario?

  1. BluejackingAnswer
  2. B
    Bluesnarfing
  3. C
    Evil Twin
  4. D
    RFID Skimming

Answer

Bluejacking
Bluejacking is the practice of sending unsolicited messages or contact cards (vCards) to Bluetooth-enabled devices within close proximity. Because no sensitive information or files were exfiltrated from the victim's device, the activity is classified specifically as Bluejacking.

Step-by-Step Solution

1
Identify the attack medium and symptoms
Unsolicited messages and contact cards were pushed directly to a mobile device over a Bluetooth connection.
Analyzing the medium narrows the candidate attacks to Bluetooth short-range wireless exploits.
2
Evaluate data impact to differentiate specific attack indicators
The investigation verified that zero data was accessed, stolen, or modified.
Bluejacking is limited to sending unsolicited messages (spam), whereas Bluesnarfing involves active data theft.
