Can a hacker gain access to a server via anonymous FTP?
I recently noticed from my "LogWatch" emailed to me daily that there were a few people trying to access the server via FTP and one of them was successful getting in via anonymous login.Mar 20 17:25:04 seng proftpd[26799]: xxx.*********** (ABordeaux-101-1-2-230.abo.wanadoo.fr[193.252.171.230]) - ANON anonymous: Login successful.
I searched the server but can't find anything wrong as it works fine.
How do I check if he has done any damage? I have disabled proFTP temporary. There are only a few of my sites on the server.
Any help is much appreciated.
