Approximately 1.5 million passwords for the popular dating site eHarmony have been stolen. The leak was linked to the same unknown hacker who recently stole passwords of LinkedIn users. According to Ars Technica, the hacker has posted 8 million encrypted passwords to underground forums.
eHarmony officials confirmed that a leak had occurred and instructed its users to change their passwords. But eHarmony declined to say how the leak had happened.
"After investigating reports of compromised passwords, we have found that a small fraction of our user base has been affected," the dating website announced.
The Washington Post reports that sites like LinkedIn and eHarmony are attractive targets to criminals because the sites allow hackers to easily access personal data. With LinkedIn, hackers can steal information from the site to use in email "phishing" scams.
"When somebody has the keys to your business and personal kingdom, that gives them all sorts of powerful information," Mary Landesman, senior researcher at security firm Cloudmark, told Reuters. "They might be able to use it for years."
