Can AirDrop be used to spy?

Answered by Michael Wilson

AirDrop is a feature on Apple devices that allows users to wirelessly share files with nearby devices. It is a convenient and efficient way to transfer documents, photos, and other files seamlessly. However, recent research has highlighted a potential privacy gap in AirDrop that could be exploited by hackers for spying purposes.

Researchers at a German university have discovered that AirDrop can be used by nearby hackers to obtain the phone numbers and email addresses of individuals using the feature. This is concerning as it could potentially lead to spamming, phishing attempts, or even targeted attacks on unsuspecting users.

The privacy vulnerability lies in the way AirDrop handles the identification of nearby devices. By default, AirDrop is set to allow connections from everyone, which means that any device within range can see and potentially send files to your device. While this makes file sharing convenient, it also opens the door for potential abuse.

The researchers found that by using simple tools and techniques, an attacker could easily collect the phone numbers and email addresses of users who have their AirDrop settings set to receive files from everyone. This is possible because AirDrop broadcasts a user’s contact information to nearby devices, even if the user does not accept the file transfer.

To make matters worse, even when AirDrop is set to receive files only from contacts, hackers can still potentially exploit the feature. By creating a malicious contact with a crafted phone number or email address, they can trick AirDrop into revealing the user’s contact information.

This privacy gap in AirDrop highlights the importance of being cautious when using wireless file sharing features. While Apple has implemented some security measures, such as requiring user confirmation for file transfers, the default settings can still leave users vulnerable.

To protect yourself from potential spying or privacy breaches via AirDrop, there are a few steps you can take:

1. Adjust your AirDrop settings: Open the Control Center on your device and tap on the AirDrop icon. From there, you can choose to receive files from Contacts Only or turn off AirDrop completely.

2. Be mindful of your surroundings: AirDrop works within a certain range, typically around 30 feet (9 meters). Avoid using AirDrop in crowded public places where there might be potential attackers nearby.

3. Keep your device updated: Apple regularly releases software updates that include security patches and bug fixes. Make sure you keep your device’s operating system up to date to benefit from these improvements.

4. Educate yourself about potential risks: Stay informed about the latest security vulnerabilities and privacy concerns related to AirDrop and other wireless sharing features. By being aware, you can take appropriate measures to protect your personal information.

While AirDrop can be a convenient tool for file sharing, it is essential to be aware of the potential privacy risks. By understanding how the feature works and adjusting your settings accordingly, you can enhance your privacy and minimize the chances of falling victim to spying or privacy breaches.
