What caught my eye was a few interesting choice remarks made in the article. First, they called their 22,000 node botnet "low-value." What, pray tell, makes this botnet particularly low value? Is it what hackers would charge to rent/sell it? Is it the number of nodes (a mere 22,000)? I think this is a great illustration of the inflated grandness that media has really driven to botnet stories...apparently botnets under a quarter-million nodes are worth less consideration. Yet by the article's own admission, it only took a scant 60 nodes to DDoS their target website off the Internet. Make no mistake, 22,000 nodes at an attacker's command can do a considerable amount of damage to just about any target. There are even supercomputers listed on the world's top 500 supercomputers list that leverage far fewer than 22,000 nodes. I would hardly trivialize a 22k node botnet with the label "low-value," as it desensitizes everyone to the overall threat that any sized botnet can represent.
Second, the article mentions they "acquired" their own botnet "after visiting some chatrooms" on the Internet. I wish they had provided a bit more details here...did they troll chat rooms until they found a botnet for sale, and purchase it? Or did they intercept an IRC-based command and control channel of the bots, thus hijacking the botnet to do their bidding? Either way, their candor regarding the ease of acquiring a botnet seems strange. I would think the story of how anyone can "visit some chatrooms" and walk away with a botnet would be more sensational than filling some demo inboxes with spam.
As an aside, the "how a botnet works" graphic they include in the article was a bit weird as well; the truncated version you see in the article leaves a lot to be desired ("Hacker -> virus"?). You have to click on the image to get the full chart, and then things become clear.
Until next time,
