A breach of the LinkedIn social networking site has led to the release of 6.4 million hashed e-mails with corresponding passwords. LinkedIn has confirmed that this breach occurred and that the data dump is valid. LinkedIn staff has noted that members with affected accounts will notice that their password is no longer valid. According to LinkedIn's blog, affected members will also receive an e-mail (without links) containing instructions for resetting your password.
All LinkedIn users are urged to change their passwords immediately via the LinkedIn website. If a LinkedIn password was used on other sites or accounts, that password should be changed immediately. Users are reminded to use different passwords for different accounts and to never use a work password on other accounts. Due to the possibility of phishing, users should be wary of e-mails purporting to be from LinkedIn, especially e-mails regarding password changes or account information. E-mails from LinkedIn regarding password or account changes will not contain links. (See LinkedIn’s blog for further details https://blog.linkedin.com/).
