SUExec might be at play, some other process, some user with ssh access, some back door, consider the permissions and owner of the directory containing the files, if it's nobody then anybody could have written to it. All in, ask the ISP to check logs and history, ensure all your permissions on directories are tight, and that you don't have any scripts on there that can be abused and that they are "safe" - then you're clear :) Best, Nathan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
