From the hackers point of view, it is kind of a smart move. Most webmasters probably won't check their sites on mobiles, and this can go undetected for a long time.
Change file permissions, and if you have installed third party applications get them up to date. If the hacker can get access to your .htaccess file, then they probably have access to the rest of your files too.
