Recently I had an attack on this website, as I run a WordPress site this is not an isolated incident. However, in this instance it was a rather aggressive attack compared to the bandwidth\u00a0I have available. The attacker in this case was saturating my connection\u00a0with POST commands to wp-login.php as apposed to the usual attacker who send requests every few seconds, in an attempt I presume to not be noticed.<\/p>\n

\"Same<\/a>
Same server, same file.<\/figcaption><\/figure>\n

Knowing that this was a sustained attack I first turned to enabling Windows authentication to wp-login.php, this made things worse as the data sent from a HTTP 401 error to this page used more data than WordPress denying access.<\/p>\n

\"A<\/a>
A 401 error transfers more data than a 200 error.<\/figcaption><\/figure>\n

Failing this, I blocked the IP address from IIS so it will return a 403 error, this brought the data sent back down to normal but still the attack continued.<\/p>\n

As a last resort, I performed a lookup on the attacking IP via the WHOIS database, and discovered the attacking computer was on a hosted server in Malaysia:<\/p>\n

The website dawhois.com was the first best match and reveled that the hosting service for this site was ipserverone.com, and in desperation to solve this I contacted the abuse email listed above.<\/p>\n
I have often contact ISPs in this method when receiving an attack, but none have come to fruition, not even a response, this time I got an answer:<\/p>\n
Hi James,<\/p>\n
We are sorry to hear that, could you please verify now, is still got attack to your site?<\/p><\/blockquote>\n
 <\/p>\n
Checking that the attack is still going on, I replied that is is still happening:<\/p>\n
Hi James,<\/p>\n
Seems that I’ve disabled an access few sites that contain suspicious codes.<\/p>\n
Is the issue persist?<\/p><\/blockquote>\n
 <\/p>\n
Checking again, it stopped! Guessing from the fact that the attack continued after changing responses from my server to 401 and 403, it was a bot running, but many thanks to Mohd and the people at ipserverone for stopping this attack and giving me back my bandwidth!<\/p>\n
