Evolution in botnet strategy: Mini-swarms

Security researchers are warning that botnets are using a strategy of splitting into smaller swarms to avoid detection. Security firms F-Secure and Israel-based Finjan believe that the trend appears as an evasive technique as opposed to previous techniques of large swarms that can be detected.

Security researchers are warning that botnets are using a strategy of splitting into smaller swarms to avoid detection. Security firms F-Secure and Israel-based Finjan believe that the trend appears as an evasive technique as opposed to previous techniques comprising large swarms that can be detected.

The TechWorld reports that the split of the botnets may be an evolutionary step in trying to get under the radar of surveillance measures. The splitting of botnets in no way reduces their strength. Botnets are increasingly appearing as a potent threat to businesses online (Processor). There are rumors of emerging markets itself for botnet trading.

The architecture of the Internet is such that a definite countermeasure to the DDoS attacks is hard to implement. The computing power that thrives in the botnets makes the task all the more tough.

While researchers believe that reputation-based services and IP detection systems are the best bet in the long term, with estimated size of nets ranging to millions of hosts, the effectiveness of countermeasures is yet to be ascertained.
