"I suspect that a sizable percentage of small botnets are those developed by people who understand or are operating inside a business as employees or by criminal entities that have dug deep and gotten insider information...We've seen a growth in the number of sites that offer the sale of corporate documents that were extracted from the bots." - Gunter Ollmann

Intrusion Defense School is now in session
Your organization's ability to fend off spyware, viruses and increasingly savvier attacks hinges on the strength and cohesion of your intrusion defense strategy. Intrusion Defense School puts the pieces of intrusion defense -- antivirus, antispyware, IDS/IPS, etc. -- in perspective to help you implement a strategy that meets your organization's needs. Take advantage of this free course today!


A micro-botnet, also called a mini-botnet or baby botnet, is a small network of Internet-connected computers that have been hijacked to attack specific companies or individuals within a company. Micro-botnets are often used in corporate espionage. Typically, the bots will monitor the enterprise network to identify key individuals and assets and target them for attack. The bots are used to seek out information like financial authentication passwords or data that can be sold to competitors.

Because there are usually fewer than one hundred computers to control in a micro-botnet, attackers can fine-tune an exploit to circumvent an enterprise intrusion detection system (IDS) or firewall. A successful micro-botnet infiltration often depends on social engineering because it's much easier to gain access and hide a small botnet's activities when the attacker has legitimate credentials. Red flags indicating the presence of a micro-botnet include new spikes in an individual's normal traffic patterns or quickly accelerating rights in a specific end user's permissions.

> According to Gunter Ollmann, VP of research at Damballa, small botnets account for 57 percent of all botnets.
