Hackers have illegally accessed Monster.com and stolen personal details from an uncertain number of its 75 million users, Bloomberg reports. The hackers snatched user IDs, passwords, contact information and more, though resumes weren’t accessed. Users should be on the lookout for bogus e-mails that appear to come from employers, and may be forced to change their passwords, the site said.
All 4.5 million of Monster’s UK users were hit, the Times of London adds—though that story comes with a banner reading, “This article is the subject of a legal complaint.” Monster says it doesn’t yet know if the UK was affected. A 2007 virus also targeted Monster, the Washington Post notes, stealing data on 1.6 million users before it was shut down.
