Bitsy Boffin writes "Xtra, the largest ISP in New Zealand, which outsources email provision to Yahoo, has in the last two days been subject of a widespread email compromise, causing potentially thousands of accounts to send SPAM messages to every address in their webmail address books.

Telecom NZ are advising those affected to change their passwords."
