Manufacturing Recovery from LockBit in 72 Hours

Situation: LockBit 3.0 struck a UK manufacturing company at 17:00 on a Friday — a deliberate timing choice by the threat actor. With 340 employees and 90% of systems encrypted, production lines halted immediately. Estimated downtime cost was £80,000 per day. The ransomware demand was significant.

Response: Binary Response was engaged within 90 minutes. Rapid triage identified that the OT (operational technology) network had not been fully compromised and was isolated before encryption could spread to production control systems. Clean backups were identified from an air-gapped backup server. Parallel negotiation advisory was provided while technical recovery proceeded — ultimately the ransom was not paid.

Outcome: Core systems were restored within 72 hours. Full production resumed by Monday morning. Total cost avoidance was £420k compared to the projected £600k+ had recovery taken the industry average of 21 days. ICO was notified. Post-incident forensics confirmed zero data was leaked.
