One of my sites has been under mass attack by bots for a month now, without cease. It’s cost me (and my developer partner) time, money, and an undue amount of stress. It’s undermined my analytics and stats.
And while there are a couple things we’ve been able to do to minimize the damage, essentially there’s no way to stop it. It just. keeps. coming. And frankly, if it continues, and spreads, there could be big repercussions across the web on ad revenue and analytics.
What I Know
The attack started on February 21, 2012, around noon. I keep an OCD-level eye on my traffic, and I noticed a big jump in direct traffic. This is unusual, because this particular site is less than a year old, and has not had a chance to develop a lot of branding yet. It’s pretty well situated in the search engines for its niche, but not that many people know it by name. Anything more than twenty or thirty percent direct traffic would definitely be odd. And then I started noticing some other strange behaviors:
- All the traffic was reported as Internet Explorer (versions 6 through 9)
- All the traffic was reported as Windows (XP through Win 7)
- The traffic was coming from all over the world (and the site is focused on ONE state in the US) and from thousands of IP numbers & ISPs.
- It was all hitting the home page and leaving immediately. My bounce rate quickly soared to about 99%
- There was nothing – no one thing – that I could pinpoint to block this traffic from coming in. No commonality.
- It was executing javascript – because it showed up in Google Analytics, Statcounter & Woopra.
Strangest of all, the traffic was *slow* – drip drip drip. Never so much to come anywhere near a DDOS, or have an effect on the server, but at any given point, there would be six to ten “visitors” on the site at a time. While it looked very much like actual human browser traffic, it wasn’t difficult to conclude that this was something automated.
