eHarmony and Passwords Stolen

Some customers of CBS Corp. (CBS)’s music site and EHarmony Inc.’s dating site had passwords stolen.

eHarmony, the “No 1 Most Trusted Dating Site,” stores the personal details of millions in the USA, UK, Australia, Canada and Brazil. The dating website was founded in 2000 and is based in Santa Monica, California. Over 500 people in the U.S. get married because of the site every day. 1.5million of eHarmony’s 20million-plus users have had their passwords hacked.

“After investigating reports of compromised passwords, we have found that a small fraction of our user base has been affected,” wrote eHarmony’s Becky Teroka. eHarmony has reset the passwords for those with compromised accounts. At least 420 of the passwords in this list contained the strings “harmony” or “eharmony.” These hashes found on the list do not contain the corresponding login names, making it impossible for anyone to use them to gain access to a particular user’s account.

Here is eHarmony’s response on their blog
