We present two novel noncooperative MAC layer fingerprinting and tracking techniques for
Wi‐Fi (802.11) enabled mobile devices. Our first technique demonstrates how a per‐bit …

MAC address randomization is a common privacy protection measure deployed in major
operating systems today. It is used to prevent user-tracking with probe requests that are …

We propose a simple active method for discovering facts about the chipset, the firmware or
the driver of an 802.11 wireless device by observing its responses (or lack thereof) to a …

As of IEEE 802.11 n, a wireless Network Interface Card (NIC) uses Channel State
Information (CSI) to optimize the transmission over multiple antennas. CSI contain radio …

The recent spread of everyday-carried Wi-Fi-enabled devices (smartphones, tablets and
wearable devices) comes with a privacy threat to their owner, and to society as a whole …

We present several novel techniques to track (unassociated) mobile devices by abusing
features of the Wi-Fi standard. This shows that using random MAC addresses, on its own …

The only available IEEE 802.11 network identifiers (ie, the network name and the MAC
address) can be easily spoofed. Consequently, an attacker is able to fake a real hotspot and …

The ubiquity of 802.11 devices and networks enables anyone to track our every move with
alarming ease. Each 802.11 device transmits a globally unique and persistent MAC address …

Motivated by the proliferation of wireless-enabled devices and the suspect nature of device
driver code, we develop a passive fingerprinting technique that identifies the wireless device …

Wi-Fi (IEEE 802.11), is emerging as the primary medium for wireless Internet access.
Cellular carriers are increasingly offloading their traffic to Wi-Fi Access Points to overcome …
