The Ransomware Landscape in 2026

Ransomware attacks against Saudi financial institutions have evolved significantly. Threat actors no longer focus solely on encrypting data; they now employ multi-stage tactics including data exfiltration, supply-chain compromise, and operational disruption. Financial institutions report increasing pressure from attackers who threaten to publish sensitive customer data or disrupt critical payment systems, amplifying the business and reputational impact of incidents.

The shift toward targeting operational technology (OT) environments—payment systems, ATM networks, and core banking infrastructure—poses particular risk. Unlike traditional IT ransomware, OT-focused attacks can directly interrupt service delivery and trigger regulatory incident notifications under the Saudi PDPL and SAMA guidelines.

Regulatory Expectations and Compliance Frameworks

The Saudi Monetary Authority's Cybersecurity Framework (SAMA CSF) and the National Cybersecurity Authority's Essential Cybersecurity Controls (NCA ECC) establish clear expectations for ransomware preparedness. Both frameworks require:

  • Incident response and business continuity planning with documented recovery time objectives (RTOs) and recovery point objectives (RPOs)
  • Segmentation and access controls to limit lateral movement and contain breaches
  • Backup and recovery validation tested at least annually and isolated from production networks
  • Threat intelligence sharing with SAMA, NCA, and peer institutions
  • Third-party risk assessment covering vendors, payment processors, and cloud service providers

The Saudi Personal Data Protection Law (PDPL) reinforces these obligations by requiring timely incident notification, data protection impact assessments, and documented security measures. Financial institutions must now demonstrate that ransomware resilience is not an afterthought but a core component of their data governance and risk management programs.

Key Resilience Priorities for 2026

Immutable Backups and Offline Recovery. Attackers routinely target backup systems to maximize pressure. Institutions should maintain offline, geographically dispersed backups with no direct network connectivity. Regular recovery drills—not just backup validation—are essential to confirm RTOs are achievable.

Zero-Trust Architecture. Implement identity and access management (IAM) controls that verify every user and device, regardless of network location. Multi-factor authentication (MFA) on all critical systems, particularly those handling payment processing or customer data, remains a foundational control.

OT-IT Convergence Security. As payment systems and banking networks increasingly integrate, security teams must apply consistent monitoring, patching, and segmentation across both domains. Dedicated SOC (Security Operations Center) capabilities for OT threat detection are becoming essential.

Supply Chain Resilience. Financial institutions depend on third-party vendors for settlement, compliance, and infrastructure services. SAMA CSF and NCA ECC require documented vendor security assessments, contractual security obligations, and incident notification clauses. Regularly audit vendor compliance and maintain a current inventory of critical dependencies.

Ransomware Negotiation and Reporting Protocols. Establish clear, pre-incident decision frameworks on whether to engage with threat actors. Coordinate with legal, compliance, and SAMA to understand reporting obligations under the PDPL. Document all communications for forensic and regulatory review.

Practical Implementation Steps

Security leaders should prioritize:

  • Conducting a ransomware risk assessment aligned with SAMA CSF and NCA ECC maturity levels
  • Establishing a cross-functional incident response team with defined roles and escalation paths
  • Implementing security information and event management (SIEM) and extended detection and response (XDR) tools to detect early indicators of compromise
  • Running tabletop exercises simulating ransomware scenarios, including communication with regulators
  • Documenting and testing recovery procedures for critical business functions monthly

Ransomware resilience is not a one-time project; it requires continuous refinement, investment in people and technology, and alignment with evolving regulatory expectations. Financial institutions that embed these practices into their operational and governance frameworks will be better positioned to detect, respond to, and recover from ransomware incidents while maintaining customer trust and regulatory compliance.
