To investigate whether a large-scale Bluetooth worm outbreak is viable in practice, we conducted controlled experiments and we gathered traces of Bluetooth activity in different urban environments to determine the feasibility of a worm infection.   date/time of measurement start: 2005-11-16date/time of measurement end: 2005-11-26  collection environment: Even if a worm could exploit a security vulnerability in the Bluetooth protocol to replicate itself, a large-scale Bluetooth worm outbreak might never develop. If vulnerable Bluetooth devices are few and far between, and most inter-device contacts are short, a worm might never reach many victims. In this case, the threat of a largescale Bluetooth worm infection is minimal. To investigate these questions, we examined whether a large-scale Bluetooth worm outbreak is viable in practice. For this, we collected traces of Bluetooth activity and conducted controlled experiments in a Bluetooth environment.network configuration: We used Palm Tungsten T PDAs having 16MB of RAM with PalmOS version 5.0 to scan for Bluetooth devices. The Bluetooth radios of our PDAs are similar to the ones found in most commodity cell-phones: our empirical tests found that our PDAs' ranges are about 10 meters in an urban environment corresponding to the specifications presented on Palm's website. Because a Bluetooth inquiry is a power-intensive procedure, we used a total of eight scanners. Each device sends "inquiries" over its Bluetooth interface. Our inquiry rate is variable: we increase it when no devices are discovered, and we decrease it when others answer our probes. We issue inquiries at least once every 10 seconds but never more often than once every 3 seconds. This variable rate deals with congestion scenarios when several devices answer simultaneously.data collection methodology: We collected three different traces of Bluetooth activity. Two of our traces are gathered inside Pacific Mall and Eaton Centre, two malls in Toronto, Canada. We gathered the third trace while riding the Toronto subway system. These three locations provide a broad coverage of different density and mobility characteristics one might find in various urban destinations. When collecting these traces, we had a behavior compatible to the environment we were scanning. For example, we were casually walking in the malls, we stopped briefly by their food courts, and we stood still while riding the subway. In this way, our data illustrates a scenario where an attacker behaves inconspicuously while launching a Bluetooth worm. We used two devices scanning simultaneously to collect the Eaton Centre and the Subway traces. We used only one device to collect the Pacific Mall trace.sanitization: We have anonymized the MAC addresses of the discovered devices.Tracesettoronto/bluetooth/encountering Traceset of Bluetooth activity in different urban environment.files: pacificMall.txt, eatonCenter.txt, subway.txtdescription: Traceset of Bluetooth activity in three different locations which have different density and mobility characteristics one might find in various urban destinations.measurement purpose: Network Security, Computer Malware (Worms) Investigationmethodology: We collected three different traces of Bluetooth activity.

If the foreign device misses two consecutive Bluetooth inquiries, we do not "patch" the encounter. We have anonymized the MAC addresses of the discovered devices. We preserved the first three octets of the original MAC address, however we have generated random three octets for the last three octects of the MAC address. In short: anonymized_MAC = first_3_octets(orig_MAC) + random_3_octetstoronto/bluetooth/encountering TracespacificMall: Trace of Bluetooth activity in Pacific Mall, a mall in Toronto, Canadaconfiguration: Each line in the file corresponds to one "encountering", where one of our scanners encountered a foreign Bluetooth device.

We placed one device on a wall at a T-junction hallway, while a person carried another device pacing themselves at a constant speed. The mobile device first issued inquiry requests. Once the stationary device is discovered, the mobile device transmitted a file. We performed several experiments. We set the size of the file at 500 bytes and at 25KB. We moved the mobile device at a speed of 1 m/s, corresponding to a typical walking speed, and 2 m/s, to approximate the relative speed of two people walking in opposite directions. Each experiment is repeated five times. We chose the T-junction hallway because it combines both line-of-sight and obstructed inter-device transmissions. There are five trials for each setting of moving device's speed and transfer data (except when we are transffering 25KB and the device is moving at 2m/s; in this case, we only have four successful trials.)format: 1. moving device's sp
