These mailing lists received a phishing scam email, asking recipients to reply to an external (non-w3.org) email address. This is a common phishing technique and generally speaking you be wary of email requests soliciting identifying information.
We would never ask someone to send their credentials via email. If you sent your credentials please change your password immediately using the link below and send me a private mail (not to the mailing lists) so that I can gather data on this scam. http://www.w3.org/Help/Account/ChangePassword/ -- Ted Guild <t...@w3.org> W3C Systems Team http://www.w3.org
