If you are on LinkedIn, as I am, today is a good day to change your password. It seems that about 6.5 million LinkedIn usernames an password have found their way onto a Russian cyber-crime website. While LinkedIn initially disputed the report of security researcher Per Thorsheim, they recently admitted that they had lost control of some users’ credentials and “apologised for the inconvenience this has caused our members”.
You can check to see if your password was one of them at LastPass.
So I changed my password, and recommend strongly that you do as well. These days passwords need to be longer than 12 characters to withstand attempts to crack the password using software and powerful computers.
