CBS Corp.’s Last.fm music site and the EHarmony dating service said some user passwords were stolen, a day after another online company, LinkedIn Corp., confirmed a security breach.
“We are currently investigating the leak of some Last.fm user passwords,” the London-based company, which recommends music to listeners, said today on its website. “As a precautionary measure, we’re asking all our users to change their passwords immediately.”
Closely held EHarmony, based in Santa Monica, California, said it reset the passwords of affected members, after investigating reports some were compromised.
“We have found that a small fraction of our user base has been affected,” EHarmony said on its website. “We are continuing to investigate.”
Last.fm, with almost 40 million users, will update customers on the status of the breach through its Twitter account, Luke Fredberg, director of international corporate communications for CBS in London, said in an interview. He declined to comment beyond the statement, which didn’t specify how many accounts were affected.
LinkedIn, owner of the world’s biggest professional-networking site, confirmed yesterday that some of its 160 million users’ accounts were affected by a security breach. The Mountain View, California-based company apologized to customers in a blog post and said members will know if their accounts were affected because their passwords will no longer be valid.
CBS, the New York-based broadcaster controlled by Chairman Sumner Redstone, added 0.6 percent to $32.13 at 2:42 p.m. in New York trading. The shares gained 18 percent this year before today. LinkedIn gained 1.5 percent to $94.50 and was up 48 percent so far this year.
