Traditionally, DDoS is an avenue of profit for botherders. But today’s botnets have evolved to include several attack vectors other than DDoS that are more profitable. And just as any business-oriented person would do, attackers follow the money.

As a result, botherders are targeting enterprise and network software, since residential devices have become over saturated. The days of simple credentials-based attacks are long behind us. Attackers are now looking for enterprise devices that will help expand their offerings and assists in developing additional avenues of profit.

A few years ago, when IoT botnets became all the rage, they were mainly targeting residential devices with simple credential attacks (something the DDoS industry does not prevent from happening; instead we take the position of mitigating attacks coming from infected residential devices).

From Personal to Enterprise

But now that attackers are targeting enterprise devices, the industry must reevaluate the growing threat behind today’s botnets.

We now have to focus on not only protecting the network from external attacks but also the devices and servers found in a typical enterprise network from being infected by botnet malware and leveraged to launch attacks.

In a blog posted on MIT’s Technology Review titled, Inside the business model for botnets, C.G.J. Putman and colleagues from the University of Twente in the Netherlands detail the economics of a botnet. The article sheds some light on the absence of DDoS attacks and the growth of other vectors of attack generated from a botnet.

In their report, the team states that DDoS attacks from a botnet with 30,000 infected devices could generate around $26,000 a month. While that might seem like a lot, it’s actually a drop in the bucket compared to other attack vectors that can be produced from a botnet.

For example, C.G.J. Putman and Associates reported that a spamming botnet with 10,000 infected devices can generate $300,000 a month. The most profitable? Click fraud, which can generate over $20 million per month in profit.

To put that in perspective, AppleJ4ck and P1st from Lizard Squad made close to $600,000 over 2 years’ operating a stresser service called vDoS.

So let me ask this: If you are a botherder risking your freedom for profit, are you going to construct a botnet strictly for DDoS attacks or will you construct a botnet with more architecturally diverse devices to support additional vectors of profit?

Exactly. Botherders will continue to maximize their efforts and profitability by targeting enterprise devices.
