Analysis of almost 200,000 of the stolen passwords shows that the most common were “123456” and “password”. These passwords are easy for hackers to guess and they also pose a wider security risk because many people use the same password for every website they visit. Soon after the data was hacked, thousands of Gawker users - visitors to sites like gadget blog Gizmodo and video game website Kotaku - had their Twitter accounts hijacked because they had used the same password there.
