Hello everyone,
So a while back I was just checking the traffic-stats/graphs from my server on my ISP's site, and I noticed that 2 months ago I had a bandwidth-usage of 300GB, in a couple of days mind you. This was also at a time that I was messing around a bit with the OS's so I didnt really notice it at the time. Today I have FreeBSD 8.2 with IPF ,SSHguard and DirectAdmin installed. And I used to get daily, almost hourly bruteforce attack detected warnings.
Last couple of weeks I got none of those (after upgrading to 8.2 with sshguard). However...today I got one warning of a bruteforce attack on dovecot for 10 failed login attempts. So decided to check the traffic stats again, and turns out I used 17GB of traffic in 1-2 days, at the beginning of this week. This site has only a couple of websites on it, which are all very low traffic.
So do these sudden spikes in traffic mean that my server is hacked, and used for something..like a spambot or something? Cause i'm sure that 17GB wasnt because of me.
Thanks in advance.
