Preface
LinkedIn.com was hacked in June 2012 and a copy of data for 167,370,910 accounts has been obtained by LeakedSource which contained emails only and passwords.
LeakedSource has been online for mere months. We’ve accumulated hundreds of databases, not through a miraculously successful spate of hacking attempts, but by scouring the internet and dark web for data. Some of what we find is very new, some is fairly old. We’re scavengers, not hackers — we don’t get to pick and choose. You can search for yourself in the hacked LinkedIn.com database and many others on our main site. If you are in this database, contact us and we will remove you from our copy for free.
Anyone may use the information on this page for free in any capacity provided LeakedSource is given credit and a link back.
Passwords
Passwords were stored in SHA1 with no salting. This is not what internet standards propose. Only 117m accounts have passwords and we suspect the remaining users registered using FaceBook or some similarity.
The following table is the top passwords used.
