Most of the people use common passwords in their online accounts like "password", "12345", "qwerty", "abcdef", "asdfjkl", "god", "jesus", "connect", "career" and so on. These common passwords are extremely dangerous, not only because they are weak words but also because they are very common and any hackers can make a guess .

Last week, 6.5 million encrypted LinkedIn passwords were hacked and posted online in a Russian Hacker Website. LinkedIn has confirmed hacked passwords in their company blog post saying "We can confirm that some of the passwords that were compromised correspond to LinkedIn accounts,". LinkedIn also points out that anyone who hasn't changed their password in a while can benefit from recent security enhancements if you change things up now, including hashing and symbols in the passwords.

A security company Rapid7 has created an infographic to illustrate what happened in LinkedIn password hacking, along with pointing the common mistakes users usually do while setting their passwords. They have also compiled a list of the top 30 LinkedIn passwords cracked by hackers along with a basic breakdown of the numbers. Check out the infographic to get idea about how to avoid using common passwords.
