LinkedIn hashes base leaked?

Yesterday, on the hash forum for forum.insidepro.com, a user under the nickname dwdm asked for help in selecting passwords for the database with SHA1 hashes:
http://forum.insidepro.com/viewtopic.php?p=96122 (At the moment the link does not work, Google's cache )

But the link works with those hashes themselves. The database has about 6.5 million SHA1 hashes without salt.

Users who helped dwdm noticed a pattern with passwords:


Many users confirm that the hash of their password from linkedin is in this database.

In any case, changing your password to linkedin.com today will not hurt.

UPD. The original link to the archive with a database of hashes was deleted from the Yandex disk. Therefore, the mirror here or here flooded cyberlife , or here flooded deniszh

UPD2. There was a site http://leakedin.org/ , where you can check whether your password is in that same database hashes
