380,000 passwords released in ad blunder

Around 380,000 customers of Swedish broadband supplier Bredbandsbolaget have been told they must change their internet password after the company sent out the details as part of a direct mail campaign.

Bredbandsbolaget, which is a subsidiary of Norway's Telenor, wanted to persuade its customers to download free music, and sent advertising material to 380,000 customers in an open letter. But the username and password was inadvertently printed on the letter too.
