A critical examination of AirDrop and Quick Share security flaws reveals six significant vulnerabilities that can be exploited by attackers within wireless range. Learn how to protect yourself from these exploits and stay one step ahead of cyber threats.
AirDrop and Quick Share vulnerabilities were discovered by two security experts.An attacker can crash the sharing service on a Mac or iPhone with just a laptop, without prior connection or user interaction.Two Quick Share bugs allow an attacker to bypass session checks and force a connection into an "accepted" state.The vulnerabilities are classified as local attacks, requiring the attacker to be within 10-30 meters of the targeted device.Patches have been released for two AirDrop bugs and one Windows flaw, while Samsung's bugs are still under investigation.Users can protect themselves by updating their devices, turning off "Everyone" visibility, and keeping AirDrop on "Contacts Only".
AirDrop, Apple's wireless file-sharing feature, and Quick Share, Google's counterpart, have long been touted as convenient ways to transfer files between nearby devices without the need for cables or a shared network. However, recent research by two security experts, Arash Ale Ebrahim and Nils Ole Tippenhauer, has shed light on six significant security flaws in both AirDrop and Quick Share that can be exploited by attackers within wireless range.
The researchers' findings, published in a new research paper, reveal that an attacker with just a laptop and no prior connection can crash the sharing service on a Mac or iPhone set to receive from anyone, with no tap or prompt. This vulnerability is particularly alarming, as it allows an attacker to take control of the device without any user interaction.
The researchers also discovered two Quick Share bugs that bypass Samsung's session checks and trigger a potentially exploitable crash in Google's Windows app. These flaws allow an attacker on the same Wi-Fi network to force a connection into an "accepted" state, keep it alive, or make the server return attacker-supplied IP and port values.
In contrast to remote attacks, which can target devices across the internet, these vulnerabilities are classified as local attacks, requiring the attacker to be within about 10 to 30 meters of the targeted device. While this limits their potential impact, a single attacker in a crowded place like an airport, train, or conference can still reach many devices at once.
The researchers tested only their own hardware and released their tools openly, allowing other security teams to reproduce the findings. To mitigate these vulnerabilities, Apple has patched one of the three AirDrop bugs and assigned it a CVE, while Google paid a bounty for the Windows flaw and has landed a code fix. Samsung's two bugs are still under investigation.
To protect yourself from these vulnerabilities, it is recommended that you update your device to the latest version available (iOS and macOS 26.5.2) and keep AirDrop on "Contacts Only" or off rather than "Everyone." On Quick Share, leave it out of "Everyone" visibility when you are not actively receiving a file.
The discovery of these security flaws highlights the importance of regular software updates and user awareness in protecting against cyber threats. As technology continues to evolve, it is crucial that manufacturers prioritize security and transparency in their products.
