DDoS for Hire – More cooperation, or new competition?

I’ve always been interested in DDoS attacks, not only for their technical aspects, but also their social, economic, or political aspects. This past summer, several of us were closely watching a DDoS group that was fairly aggressive and diverse in its attack targets. This group, known as the “hack-off” group used the domains ‘” & “” for their command and control. What was particularly interesting about ‘hack-off’ was their attack campaigns on targeted industries and groups. Such industries included:

hack-off DDoS targeted industries

* Online pharmacies
* Porn sites
* Automotive parts suppliers
* Replica Watches
* Online Gambling
* Logo Design companies
* Sporting goods and sportswear
* Healthcare products
* Electronics vendors

Many of the attacks victims were fairly high profile, and law enforcement agencies from at least 5 different countries became involved. Eventually, with the assistance of cert-ru and Affilias, the domains were suspended and by October 2009, the ‘hack-off’ crew was offline.

Recently while looking through some of our data sets, I again noticed aggressive DDoS attacks against targeted industry groups. In this case, four domains are seen being used for command and control:

New DDoS controllers

Over 250 different sites were targeted for DDoS from these controllers since November, 2009. The victim sites were fairly diverse, but were seen predominately in the following industries:

Industries targeted by atatata and friends

* Car buying sites
* Footwear
* Sporting goods
* Jewelry
* Gambling and Lottery
* Watches
* Appliances
* Travel and Tourism

The domains used by these controllers have been run on various hosting providers as described below. has also been seen dropping FakeAv as well as other malware. Another active botnet domain on the same IP as, is, however I haven’t yet seen DDoS related activity from them.

The top IP address prefaced is the currently active IP for that domain. The listing below also shows the nameserver history for each domain.

While DDoS for hire is nothing new, these particular attacks and the activity behind them remain interesting. Are these new criminal groups rising up to compete in the lucrative world of DDoS? Or are we just seeing more cooperation and consolidation of efforts among the usual and familiar players?

We’ll continue to keep an eye on any new attacks from these controllers as well as the providers from where they are hosted.
