"We tested this attack with Android versions 2.1 (Nexus One), 2.2 (HTC Desire, Nexus One), 2.2.1 (HTC Incredible S), 2.3.3 (Nexus One), 2.3.4 (HTC Desire, Nexus One), and 3.0 (Motorola XOOM) and with the native Google Calendar, Google Contacts, and Gallery apps (or respective synchronization services).
* Until Android 2.3.3 the Calendar and Contacts apps transmit any request in the clear via http and are therefore vulnerable to the authToken attack. This affects 99.7% of all Android smartphones (stats from 2nd of May 2011). Since Android 2.3 the Gallery app provides Picasa Web Albums synchronization which is also not encrypted.
* Since Android 2.3.4, the Calendar and Contacts apps are using a secure https connection. However, the Picasa synchronization is still using http and thus is still vulnerable.
* Our sniffed authTokens were valid for several days (14 days for a sniffed Calendar authToken), which enables adversaries to comfortably capture and make use of tokens at different times and locations. "
