Big deal, you say. Well, think about this: By gaining entry into your WordPress account, they can find your email address. And if you use the same password for different places you might log in, a hacker can gain access to lots of information you’d rather they not have.
If you think you’ve got a secure password, you might want to be sure. This is also another reminder that it’s best not to use the same password for lots of different accounts (email, banking, social networking sites, etc.).
From the Guardian post:
md5 -s mypassword– though use your password, not mypassword.
Second, paste that code into your favourite search engine. If it returns no results – well done! You’ve evaded that hack, for now.
