Summary

Hide ▲

The JDY botnet has expanded to more than 1,500 compromised SOHO/IoT devices, making it a larger-scale reconnaissance scanner for exposed infrastructure and follow-on targeting. It now performs targeted scanning and service fingerprinting through a centrally controlled command structure, which increases its value as a discovery layer for attackers. The network’s growth from 650 bots in early January 2024 and its spread across the U.S., Brazil, Europe, and Asia broaden its reach and resilience. Its scan results feed downstream exploitation pipelines, giving operators timely targeting data after vulnerability disclosures.

    Initial report: JDY botnet reconnaissance expansion to 1,500+ SOHO/IoT devices

    Initial Disclosure

    The **JDY** cluster first emerged inside **KV-botnet** in mid-December 2023, before the broader network was disrupted in early 2024. After that takedown, the operators kept the reconnaissance capability alive and expanded it beyond the original router-heavy footprint.
