Sorry to be the bearer of such bad tidings. Please note that I'm doing a quick copy/paste from a notification I received. I've edited it a bit. Please note that LinkedIn has weighed in with a carefully worded blog post: http://blog.linkedin.com/2012/06/06/linkedin-member-passwords-compromised/ Further details: 1. The leak took place on June 4 2. LinkedIn was using unsalted SHA-1 for their password store. 3. FYI, there are two lists. The second one appears to be from eHarmony. Unsalted MD5 used there. 4. The posted passwords are believed to be ones the cracker wanted help with, i.e., they have significantly more already cracked. Apparently phishing emails are already active in the wild based on the crack: http://bits.blogs.nytimes.com/2012/06/06/that-was-fast-criminals-exploit-lin... In other words, if you have a LinkedIn account, expect that the password has been stolen. Go change your password now. If you used that password elsewhere, you know the routine. In addition, as has been pointed out elsewhere, there's no sign LI has fixed the problem. Expect that the password you change it to will also be compromised. :-( -- A picture is worth 10K words -- but only those to describe the picture.
