Google antiphishing site exposes private user data

Info was inadvertently trasmitted via the Google toolbar in Firefox

Google has removed a few user names and passwords posted inadvertently to a phishing blacklist it compiles and makes publicly available on the Web, the Mountain View, California, company said Monday.

The login information was contained in 15 URLs submitted through Google's Firefox toolbar, which lets users report Web pages they suspect to belong to phishing sites. Most of the URLs on the list didn't have login information.

Google said it also has implemented a mechanism that detects when a submitted URL contains login data and prevents that information from getting posted to the list.

"We are in the process of notifying the users who inadvertently disclosed this information and suggesting that they reset associated passwords," Google said in an e-mailed statement.

Finjan found the sensitive information on the list and informed Google in early January, the San Jose, California, security vendor said Monday.

In addition to user names and passwords, the list also included e-mail addresses and session tokens, putting in jeopardy the users' privacy, Finjan said.

Finjan has posted a snapshot of a portion of the list here containing the offending URLs, albeit with the sensitive information blacked out.

Users of the Firefox toolbar get a chance to review the suspicious URLs they plan to submit to Google, Google said.

More information about the Safe Browsing feature in Firefox can be obtained here. The Safe Browsing feature isn't available in Google's Internet Explorer toolbar.
