Join in the Wikileaks DDoS war from your iPhone or iPad

Low Orbit Ion Cannon comes to the slab – or any browser

Choosing a cloud hosting partner with confidence

The online "infowar" precipitated by the media circus surrounding Wikileaks and Julian Assange continues, with DDoS attacks occurring against a bewildering variety of websites assessed as having either aided or failed to aid the leak-publisher – or often merely for commenting on the brouhaha.

Meanwhile, interest has focused on the methods used to mount the DDoS attacks. It appears that in general most of the muscle is coming from botnets of the usual sort: ones made up of zombie machines infected with malware using the same methods as ordinary online criminals and spammers (and just as illegal).

However, some of the battling communities – for instance the loosely organised hacktivist collective Anonymous, aligned in support of Assange and Wikileaks – also use collaborative tools where supporters can voluntarily attach their machines to a botnet in order to assist with a DDoS attack. The preferred tools are usually some version of the Low Orbit Ion Cannon (LOIC) software. Machines running LOIC can then be controlled via IRC or some other channel (again the campaigners are aping criminals by using Twitter of late).

Downloading and installing LOIC (the code is freely available at such places as Sourceforge) is simple enough, but evidently off-putting enough that not many people are doing it. The LOIC hivemind net run by Anonymous has generally had only a few hundred machines in it, far too few to mount a serious DDoS, and most of the grunt has been delivered by larger malware-based botnets controlled by individual Anonymous members (just one reportedly containing more than 30 times as many machines as the anonops.net hivemind).

But in the last day or two, a new wrinkle has begun to gain prominence. It is now possible to visit a webpage which will convert your browser into a pocket LOIC instance, delivering DDoS packets from whatever device you are using to browse – not necessarily even a computer.

As Panda Labs analyst Luis Corrons notes:

Only a browser is needed, so you can even launch the attack from your fone, I just tested it with my iPhone ... Of course I tested that it was real and worked, but I didn’t send any attack out.

Such a webpage will typically give you the option of adjusting how many requests per second to send to the target website (handy in the case of a phone or perhaps a fondle-slablet device with a limited data package and/or bandwidth) and allow you to attach an insulting message of your own devising.

This would appear to be rather less sophisticated than a proper IRC or Twitter-controlled LOIC install, but has the merit of being simpler. Whether this tremendously simple way of joining in botnets will finally mobilise large numbers of pro- or anti-Wikileaks vigilantes remains to be seen. For now, it appears that the effective DDoS attacks – and other more sophisticated meddling going on – are emanating from relatively small numbers of people.

It would seem that in general most people are aware how relatively unimportant and easily replaceable a part Julian Assange and Wikileaks have played in the release of the classified US files, which continue to mildly interest the outside world. ®

Bootnote

1) Reader be warned: Participating willingly in a DDoS attack is a crime in many countries. Even if this doesn't bother you, you download software and visit webpages of this sort at your own significant risk: campaigners on both sides have shown little in the way of scruples, and ordinary criminal scammers are now exploiting the situation too.
