New Botnet Aeternum C2 Uses Blockchain for Enhanced Resilience

Cybersecurity researchers at Qrator Labs disclosed a new botnet loader named Aeternum C2 that employs a blockchain-based command-and-control (C2) infrastructure to resist takedown attempts. The botnet stores encrypted commands on the public Polygon blockchain instead of using traditional servers or domains for C2 operations. This method enhances resilience by leveraging decentralized storage to evade disruption. No specific dates, victim counts, or technical indicators such as CVE IDs were mentioned in the reported details. The impact involves increased difficulty in dismantling the botnet due to its decentralized architecture.
