UK Regulators Urge Boards to Plan for Ransomware — April 24, 2023
UK NCSC and ICO warn legal advisers against steering organisations toward ransomware payments, reinforcing reporting duties and resilience-first response expectations.
Executive briefing: The UK National Cyber Security Centre (NCSC) and Information Commissioner’s Office (ICO) issued a joint letter to the legal profession urging solicitors and incident advisers to stop encouraging ransomware payments, warning that paying criminals rarely reduces overall risk and does not absolve organisations of reporting duties. The regulators emphasise that legal advisors should prioritise resilience, rapid recovery, and transparent reporting to authorities rather than defaulting to negotiation with extortionists. Boards must treat the letter as a signal of heightened regulatory scrutiny over incident response practices, privilege management, and breach notification decisions.
The letter clarifies that UK data protection law does not consider ransom payment a mitigation measure that lessens data breach penalties; organisations must still report qualifying incidents to the ICO within 72 hours and notify affected individuals where required. NCSC highlights that payments encourage criminal reinvestment, fuel repeat attacks, and often fail to guarantee data deletion or decryption. Legal counsel are urged to provide balanced advice that accounts for regulatory obligations, ethical considerations, and the long-term security posture of clients.
Capability focus areas
The joint communication underscores four capability areas enterprises must strengthen:
- Preparedness planning. Organisations should maintain playbooks that assume data exfiltration, double extortion, and public disclosure regardless of payment. Plans must define decision authorities, law enforcement engagement protocols, and conditions for invoking incident response retainers.
- Data governance. Strong backup strategies, segmentation, and least privilege controls reduce the operational pressure to pay. Regular testing of offline backups and immutable storage is essential.
- Regulatory readiness. Teams must understand UK GDPR, Privacy and Electronic Communications Regulations (PECR), and sectoral rules so breach assessment and reporting occur within statutory windows regardless of ransom negotiations.
- Advisor accountability. Legal and incident response partners should provide evidence-based guidance on recovery options, document advice given, and avoid conflicts of interest where ransom facilitation services are monetised.
Implementation roadmap
Boards and CISOs should coordinate a remediation programme built around the regulators’ expectations:
- Review engagement letters and retainers. Update contracts with legal counsel, insurers, and incident responders to emphasise compliance with NCSC guidance, law enforcement cooperation, and prohibition on unlicensed ransom payment facilitation. Include clauses for documenting advice and decision rationales.
- Enhance detection and containment. Deploy modern endpoint detection and response (EDR), behavioural analytics, and network monitoring tuned to ransomware indicators such as lateral movement, privilege escalation, and mass encryption attempts. Integrate with the NCSC’s Early Warning Service where available.
- Backup and recovery hardening. Implement 3-2-1 backup strategies with immutable storage, test restoration regularly, and ensure recovery runbooks account for destructive wiper variants and cloud workloads.
- Insurance and sanctions diligence. Collaborate with insurers and sanctions specialists to evaluate whether proposed payments could breach financial sanctions regimes and to document why alternative mitigation strategies are viable.
- Simulation and training. Run joint exercises with legal, communications, and executive teams focusing on scenarios where attackers leak data or demand payment. Evaluate decision checkpoints, regulatory notifications, and public messaging.
Organisations should document exercise findings and remediation commitments, feeding them into investment plans and board updates.
Responsible governance
The regulators expect a clear governance model that limits ad-hoc decision making during crises:
- Board oversight. Boards should receive regular briefings on ransomware trends, defensive investments, and regulatory expectations. Establish thresholds for escalating incidents and define who can authorise engagement with threat actors.
- Risk appetite and policy alignment. Integrate ransomware response principles into cyber risk appetite statements, ensuring policies prohibit ransom payments where unlawful (such as dealings with sanctioned entities) and emphasise compliance-first decision making.
- Transparency and record keeping. Maintain detailed logs of incident timelines, negotiations, and legal advice. These records support regulatory investigations and demonstrate good-faith compliance efforts.
- Stakeholder communication. Develop communication plans for customers, regulators, investors, and employees that emphasise remediation actions and support services, not ransom payments.
Embedding these practices in enterprise risk management frameworks will show regulators that the organisation prioritises societal and legal obligations over expediency.
Sector playbooks
- Legal and professional services. Firms advising on incidents should establish internal policies aligned with the NCSC/ICO letter, maintain registers of ransom-related advice, and provide training on ethical guidance. They should also vet third-party negotiators for regulatory compliance.
- Healthcare and public sector. Given heightened exposure, develop contingency plans that prioritise patient and citizen safety, including manual workarounds, alternative care pathways, and communication strategies that meet statutory transparency requirements.
- Financial services. Integrate ransomware response with operational resilience frameworks and PRA/FCA requirements. Perform impact tolerances testing to ensure payments can continue even during prolonged recovery.
- Manufacturing and logistics. Combine IT and OT response plans, ensuring plant operations can be isolated safely and recovery priorities consider safety-critical systems.
Measurement and assurance
Executives should track metrics that evidence alignment with regulatory expectations:
- Backup recoverability rate. Frequency of successful restoration tests across critical systems, recovery time objective (RTO) attainment, and integrity verification.
- Incident reporting timeliness. Percentage of qualifying incidents reported to ICO and other regulators within statutory timeframes, along with root cause of any delays.
- Exercise participation. Number of ransomware simulations per year involving legal counsel, communications, and executives; action closure rate from post-incident reviews.
- Advisor compliance. Share of legal and incident response partners who have acknowledged the NCSC/ICO guidance and updated their engagement terms accordingly.
- Threat monitoring coverage. Visibility metrics such as percentage of endpoints with EDR coverage, privileged account monitoring, and anomalous data transfer detection.
Coordinate closely with law enforcement by pre-registering with the NCSC’s incident reporting channels and the UK government’s National Cyber Security Programme contacts so escalations are streamlined and intelligence sharing accelerates disruption of criminal ecosystems.
Dashboards combining these metrics with qualitative insights (such as negotiation logs and regulator feedback) will equip boards to challenge preparedness and justify investment decisions.
Zeph Tech supports UK organisations with ransomware resilience programmes that integrate NCSC guidance, legal risk controls, and evidence-based incident response analytics.
Vendors and managed service providers should also attest to the guidance, embedding contractual notification timelines, cooperation clauses, and evidence of ransomware exercises so supply-chain exposures do not undermine enterprise compliance.
