UPDATE: LinkedIn confirms security breach, lays out course of action.
The Verge reports that millions of LinkedIn passwords may have been leaked online:
A user in a Russian forum is claiming to have hacked LinkedIn to the tune of almost 6.5 million account details. The user uploaded 6,458,020 hashed passwords, but no usernames. It’s not clear if they managed to download the usernames, but it’s likely that both have been downloaded. There is a possibility that this could be a hoax, but several people have said on Twitter that they found their real LinkedIn passwords as hashes on the list. Many of the hashes include “linkedin,” which seems to add credence to the claims.
On the lighter side…
I can’t remember my LinkedIn password. So if the hackers would be so kind to send it to me that’d be great.
