The story begins with that the password of a shell user took wrong hands for some reason on one of our server. Moreover the shell user had sudo access on the server. Self-respecting server operator first step is immediately saving the data and reinstall the server, excluded the chance that hackers come back to the server through a backdoor. The second step is increasing the security level on server, and the users increase their own security.

Pathauto is quite a useful module of Drupal 7.
I created a module that transforms accentuated letters and other UTF-8 characters into ASCII characters in a way that the url is SEO-friendly.
