Just heard the new of linked account breach. Quickly came up with this shell command to check if your password is compromised. Just replace the mypassword with your password.
$ wget -qO- http://www.leakedin.org/?check=`echo
-n "mypassword" | openssl sha1`
| grep 'class="danger-zone"' | grep -Po ">.*?<" |
head -n1
If your password hash is in the compromised list then the command will echo following message
>Your password was leaked and cracked. <
