DeadLock Ransomware Uses Polygon Blockchain to Harden Extortion Infra
- Engineer — Learn: No patch or config action required, but this technique — using decentralized blockchain services instead of traditional C2 — changes how defenders should think about network egress controls and ransomware resilience. Review whether your environment restricts outbound connections to blockchain RPCs and the Session messaging network.
- SOC/IR — Plan: DeadLock’s use of Polygon smart contracts and Session protocol for victim comms creates a new detection surface; build or tune detections for Session network traffic and Polygon RPC calls originating from endpoints and servers, and add this TTP to ransomware hunt playbooks this quarter.
- Leader — Learn: Ransomware groups adopting decentralized infrastructure reduces the effectiveness of traditional law-enforcement takedowns, which has implications for incident response assumptions and cyber-insurance negotiations around extortion scenarios — useful context for the next IR retainer or insurance renewal discussion.
