Firesheep Plugin Exploits Google

Researchers Vincent Toubiana and Vincent Verdot developed a Firesheep plugin that expose a data leak vulnerability in Google.

The proof-of-concept, exploiting the use of unencrypted cookies by Google’s Web History, allows  attackers to find out who your social contacts are and who is in your Google address book when you are sharing the same WiFi hotspot as him / her.

The Hacker News [2] provides a more technical overview of the technique used.

The Google Security Team has been alerted in regards to the vulnerability. While they are working on the fix, they recommend that users should not logged in to Google account when using an unsecured network [1].
