Custom Internet radio provider Last.fm on Thursday confirmed that passwords belonging to an unspecified number of it users have been compromised. “We are currently investigating the leak of some Last.fm user passwords,” the company said in a statement on its website. “This follows recent password leaks on other sites, as well as information posted online. As a precautionary measure, we’re asking all our users to change their passwords immediately.” The news comes just one day after LinkedIn confirmed an attack that saw passwords belonging to nearly 6.5 million members posted on the Web. Last.fm recommends that all of its users change their passwords immediately.
