The U.K. National Health Service says no patient data was compromised. Lulz Security apparently obtained administrative passwords for a website for a local NHS organization. The group warned the NHS of the compromise by e-mail, and posted an image of the message on Twitter. It has claimed a string of successful hacks in the past few weeks, including a U.S. public broadcasting network and Sony Pictures Pictures. The NHS said that none of its information systems had been affected by this latest incident.”]
