A recent hack of 42 million accounts with Cupid Media dating sites could be one of the biggest password breaches in history, especially in light of the information sitting around in plaintext. But it looks like the passwords might be easy to guess. More than 1.9 million accounts used the passcode 123456. Another 1.2 million went for 111111.
What security analysts are worried about is that if the users were dumb enough to use 123456 on a dating site, they are almost certain to do that on other sites.
