I just changed my password! I suggest you do the same!!
Via The Verge
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 encrypted 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 we’re hearing reports that users have found their passwords as hashes in the file. Many of the hashes include “linkedin,” which seems to add credence to the claims.
It’s worth noting that the passwords are hashed with SHA-1, which is a very secure algorithm. SHA-1 is not foolproof, but unless your password is very simple, it will take some time to decrypt. We’ve reached out to LinkedIn to determine the accuracy of the claims, but in the meantime, we recommend changing your password just in case.
