Botnet Takedowns: A Temporary Reprieve

The takedown of major botnets can be celebrated as significant victories for cybersecurity, but experts warn that it's only temporary. According to recent observations from Q2 2026, the largest botnet in Q1 had a staggering 13.5 million devices, but by Q2, this number plummeted to 2.09 million.

The coordinated international operation carried out in March 2026 is believed to have contributed significantly to this decline, disrupting infrastructure used by notorious botnets like Aisiru and Kimwolf. However, experts warn that the underlying conditions enabling large botnets remain largely unchanged.

The cost of building and operating botnets continues to decrease, while AI-powered automation makes it easier for attackers to discover vulnerable systems and compromise them at scale. The demand for DDoS attacks also remains high, with individuals and organizations willing to pay for these services providing a strong incentive for botnet operators to rebuild or create new botnets.

The use of blockchain-based infrastructure is becoming increasingly popular among botnet operators, allowing them to distribute commands without relying on a single server that can be seized. This makes disrupting command-and-control infrastructure significantly more challenging.
