Open Wireless Link

Welcome to the Open Wireless Link (OWL) project. We are researchers from the Secure Mobile Networking Lab at TU Darmstadt looking into Apple’s wireless ecosystem. Our goal is to assess security and privacy as well as enable cross-platform compatibility for next-generation wireless applications. We started by investigating the Apple Wireless Direct Link (AWDL) protocol and will go beyond. You can read our publications and use our open source code projects. If you have questions or would like to collaborate, feel free to contact us.

  • MobiCom ’18 Best Community Paper and Demo Awards

    Today, we received the MobiCom ’18 Best Community Paper Award for our paper One Billion Apples’ Secret Sauce: Recipe for the Apple Wireless Direct Link Ad hoc Protocol. The award recognizes “intellectually exciting ideas, combined with a substantive contribution in computer code, experimental data, or other artifacts deemed useful to the research community at large.” In addition, we received the MobiCom ’18 Best Demo Award (one of two) for the accompanying demo Linux Goes Apple Picking: Cross-Platform Ad hoc Communication with Apple Wireless Direct Link. We thank the juries for the awards and hope that our work can be useful for others.

  • Crashing iOS 12 Devices Remotely via Wi-Fi

    We have disclosed a vulnerability (CVE-2018-4368) to Apple that allowed us to crash iOS (and also macOS, tvOS, and watchOS) devices remotely via Wi-Fi. We demonstrate a working exploit which allows us to target a single device but also all devices in proximity in parallel. The exploit does not require any user interaction and, thus, might force a device into an indefinite boot loop. Apple has just released security updates for all of its operating systems which we recommend everyone to install.

  • MobiCom ’18 Demo Accepted

    Our demo paper Linux Goes Apple Picking: Cross-Platform Ad hoc Communication with Apple Wireless Direct Link was accepted at ACM MobiCom ’18. In the demo, we present a working prototype of AWDL for Linux-based systems. Read our paper here.

  • MobiCom ’18 Paper Accepted

    Our paper on reverse engineering and analyzing the Apple Wireless Direct Link (AWDL) ad hoc protocol One Billion Apples’ Secret Sauce: Recipe for the Apple Wireless Direct Link Ad hoc Protocol was accepted at ACM MobiCom ’18. Read our paper here. See you in New Delhi in October!
