But as detail of the latest hack materialises, are there wider concerns beyond someone maliciously accepting all your pending connection requests?
To recap, back in 2012 LinkedIn security was breached resulting in 6.5 million passwords being dumped onto a hacker forum. Shortly afterwards LinkedIn identified and disabled the affected accounts and added new security measures to their sign in process. Fast forward to May 2016 and another batch of account details from the same hack are now up for sale, with the hackers following up their 6.5 million password appetiser with a 117 million main course.
While the stolen passwords were encrypted it's taken just 72 hours for various groups to crack 90% of them and in the process reveal some frightening insights into people's password behaviour.
- 123456 - is the most common password used 1,135,936 times
- linkedin - comes in second with 207,488
- password - the security stalwart has surprisingly been edged into third place with 188,380
- 123456789 - is next with 149,916, obviously the password of choice for those who think using 123456 is bonkers
An honourable mention must also go to the password maggie which somehow gets into the top 20 after being used 30,972 times. Perhaps going to show just how many Conservative MPs and councillors are lurking in your business connections.
LinkedIn are correctly reminding users of its security best practices which contains helpful guidance on setting up two-step verification for signing in.
I must admit I've always been hesitant to attach my mobile number to LinkedIn for the fear of being bombarded with notifications. However two-step verification seems to work well and my mobile hasn't (yet) been flooded with inspirational leadership quotes....
