A hacker collective called Team Alad33n (@Galad33n) claims to have hacked Google Talk and gained access to the site’s databases by leveraging an SQL Injection vulnerability. As a result, they leaked over 900 username and password combinations on Pastebin.
“Google has left it's data unsecured, some passwords are not encrypted, some are, scroll down to check,” they wrote next to the leaked data
However, a close analysis of the data leads us to believe that this is just another fake hack done by a group that’s seeking attention.
A large portion of the information appears to be taken from other hacks, some of which date as far back as March 2012, possibly even earlier.
On some websites, the credentials are advertised as a way to make Twitter followers, which might mean that they were fished out from the social media site’s customers.
In any case, it’s unlikely that Google Talk was hacked.
