DeadLock ransomware uses blockchain to resist infrastructure takedown
- Engineer — Learn: No patch or configuration action available; the technique signals that traditional domain-takedown mitigations matter less for this operator, which is worth factoring into egress-filtering and backup-isolation architecture reviews.
- SOC/IR — Learn: No IOCs or ATT&CK-mapped TTPs are available to hunt or detect; worth absorbing for IR playbook updates, as blockchain-backed C2 limits the value of expecting law-enforcement takedown to cut off active intrusions.
- Leader — Learn: Useful framing for board-level ransomware risk discussions: blockchain-anchored infrastructure reduces the effectiveness of law-enforcement disruption as a risk mitigant, which may affect how resilient response plans need to be.
