Over a million Eharmony passwords stolen and posted online

Only a day after it was acknowledged that millions of Linkedin passwords were stolen, it appears the hacker also stole around 1.5 million passwords from Eharmony.

The dating website admitted in a blog post that after "investigating reports of compromised passwords, we have found that a small fraction of our user base has been affected".

It added that it has reset all "affected members passwords" and they will "receive an email with instructions on how to reset their passwords".

As with the Linkedin passwords, the person behind the attacks who has been using the alias ‘dwdm', posted the passwords on a Russian web forum asking for people to help crack ones he couldn't.

News site Ars Technica, which broke the Linkedin story, was told by Rick Redman, a password- cracking specialist that: "It's pretty obvious that whoever the bad guy was cracked the easy ones and then posted these, saying, 'These are the ones I can't crack.'

"I think the person has more. It's just that these are the ones they couldn't seem to get."

Users of both websites should have changed their passwords by now and ensure that if the same one has been used on other sites, those are changed as well. Those with a Linkedin account can also check out and see if theirs was one of those stolen on the Leakedin website.
