An attack on the UK's National Theatre has forced a password reset.

"The 20 February attack hit systems storing the logins of 17,000 (or around three percent) of the 500,000 plus registered with the site," writes The Register's John Leyden. "Only e-mail, password, name and contact information was disclosed by the hack. Motives and perpetrators remain unidentified."

"Affected users simply have to change their password, so the attack is no great drama," Leyden writes. "What the security breach does illustrate, however, is the folly of not using different strong passwords on separate websites. The common 'one key to open them all' approach makes even the breach on a low level account a potential risk against more sensitive webmail and online banking logins."
