Location spoofing possible with WiFi devices

15.04.2008
Positioning system used by iPhone/iPod breached

In January, Skyhook Wireless Inc. announced that Apple would use Skyhook’s WiFi Positioning System (WPS) for its popular Map applications. The WPS database contains information on access points throughout the world. Skyhook itself provides most of the data in the database, with users contributing via direct entries to the database, and requests for localization. ETH Zurich Professor Srdjan Capkun of the Department of Computer Science and his team of researchers analysed the security of Skyhook’s positioning system. The team’s results demonstrate the vulnerability of Skyhook’s and similar public WLAN positioning systems to location spoofing attacks.

Impersonation and elimination

When an Apple iPod or iPhone wants to find its position, it detects its neighbouring access points, and sends this information to Skyhook servers. The servers then return the access point locations to the device. Based on this data, the device computes its location. To attack this localization process, Professor Capkun’s team decided to use a dual approach. First, access points from a known remote location were impersonated. Second, signals sent by access points in the vicinity were eliminated by jamming. These actions created the illusion in localized devices that their locations were different from their actual physical locations.

Simple falsification

Skyhook’s WPS works by requiring a device to report the Media Access Control (MAC) addresses that it detects. However, since MAC addresses can be forged by rogue access points, they can be easily impersonated. Furthermore, access point signals can be jammed and signals from access points in the vicinity of the device can thus be eliminated. These two actions make location spoofing attacks possible.

Compromised usage

Professor Capkun explained that by demonstrating these attacks, the team hoped to point out the limitations, despite guarantees, of public WLAN-based localization services as well as of applications for such services. He said «Given the relative simplicity of the performed attacks, it is clear that the use of WLAN-based public localization systems, such as Skyhook’s WPS, should be restricted in security and safety-critical applications.»

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
