Today I woke up to an unresponsive website. When I started to look at the Apache access.log file I found a ton of IPs trying to bruteforce my wp-admin.php creds. I knew they weren.t going to get anywhere (thank you google auth), but it was doing a good job at DDOS.

Below is the oneliner I used to quickly end their fun.

1
tail -f /var/log/apache2/access.log | while read line; do echo "$line" | grep -i "post /wp-login.php" | cut -d " " -f1 | xargs -r iptables -I INPUT -j DROP -s; done
