LeakedIn: six million logins posted online

LINKEDIN, the social network for professionals, yesterday admitted it was looking into claims that millions of its users’ passwords had been leaked online.

What seemed to be almost 6.5m encrypted LinkedIn passwords were posted in a Russian forum – without the corresponding usernames – by someone claiming to have hacked into the website.

LinkedIn took to fellow social network Twitter to say: “Our team is currently looking into reports of stolen passwords.”

In a blog post last night, the company confirmed that “some of the passwords” corresponded to LinkedIn accounts but declined to specify numbers.

The New York-listed business networking website said it “sincerely apologises” for the inconvenience to its 160m-plus members.

The news came just hours after researchers accused LinkedIn’s iOS app of breaching users’ privacy by accessing their calendar information without express permission.
