Ransomware activity surged in 2025, with global incident volumes rising by more than 30 percent compared to the year before. In the same period, ransomware was present in more than four in ten reported data breaches, highlighting that attackers are increasingly integrating extortion into broad cybercrime campaigns rather than isolated file‑encryption events.

This article explains how modern ransomware tactics have evolved beyond simple encryption, why double extortion and adaptive attack vectors are shaping the threat landscape in 2026, and what organisational defences security teams should prioritise to manage risk and operational impact. 

Understanding Modern Ransomware Threats

Ransomware is malicious software designed to encrypt files or disrupt system operations, forcing victims to pay a ransom to regain access. While the basic concept remains unchanged, the methods and scale of attacks have evolved significantly.

Shift to Targeted Attacks

In the past, ransomware often relied on mass distribution through phishing emails or exploit kits, indiscriminately affecting victims. Today, attacks are more surgical. Threat actors conduct reconnaissance to identify high-value targets, including healthcare providers, critical infrastructure, and large enterprises. This targeted approach increases the likelihood of payment while reducing the attacker’s exposure to detection and law enforcement.

For instance, recent campaigns have leveraged Remote Desktop Protocol (RDP) compromises and software supply-chain vulnerabilities. Attackers exploit misconfigured systems or unpatched software to gain persistent access, then deploy ransomware across the network in a controlled manner.

Double Extortion and Data Leak Tactics

Modern ransomware groups increasingly combine encryption with data exfiltration. This strategy, known as double extortion, pressures victims to pay by threatening to release sensitive information publicly if the ransom is not paid. High-profile incidents show that this approach often results in faster compliance by organisations, particularly those handling sensitive customer data or intellectual property.

Some attackers also integrate triple extortion methods, targeting not just the primary victim but also customers, suppliers, or partners. These multi-layered tactics complicate incident response and amplify potential reputational damage.

Ransomware-as-a-Service (RaaS)

Ransomware development is no longer limited to technically skilled cybercriminals. Ransomware-as-a-Service (RaaS) platforms enable affiliate groups to launch attacks in exchange for a share of the ransom. This model has lowered the barrier to entry, broadening the pool of active attackers and increasing the frequency and diversity of campaigns.

RaaS operations are increasingly professional, mirroring legitimate software services. Affiliates receive dedicated support, technical updates, and negotiation guidance, which accelerates attack sophistication. For organisations, this means the threat landscape is larger and also more structured and adaptive.

Recent Ransomware Incidents: Learning from the Field

Examining real cases shows how attackers are adapting and where organisations still struggle.

Colonial Pipeline: Operational Risk Meets Strategic Impact

In 2021, Colonial Pipeline, a major U.S. fuel supplier, fell victim to ransomware that disrupted fuel distribution across the southeastern United States. Attackers leveraged a compromised VPN account that lacked multi-factor authentication (MFA). Within hours, systems were encrypted, forcing a temporary shutdown of pipeline operations to contain the infection.

The financial consequence extended beyond the ransom payment. The operational shutdown triggered fuel shortages, price volatility, and regulatory scrutiny. Colonial Pipeline ultimately paid a ransom, then worked with law enforcement and industry partners to recover. 

A Healthcare Provider: Double Extortion in Practice

A recent campaign targeted a mid-size healthcare provider. Attackers gained access through a phishing message that captured credentials for a privileged user. The ransomware variant not only encrypted patient records but also exfiltrated sensitive health information.

Faced with the prospect of public disclosure of protected health data, the organisation confronted both operational challenges and regulatory obligations under data protection laws. Although backups existed, the decision matrix extended beyond data restoration. The organisation had to balance disclosure requirements, patient trust, and business continuity.

This incident highlights two trends: data theft as an explicit weapon and compliance risk layered on top of operational risk.

These cases demonstrate that ransomware is rarely just a technical event. The impact often spans corporate reputation, regulatory exposure, and cross‑functional decision making.

Attack Patterns and Techniques

Understanding how modern ransomware propagates helps organisations prioritise defensive strategies. Several patterns dominate current campaigns:

• Phishing and Social Engineering: Despite advances in email security, phishing remains the primary entry vector. Attackers craft highly convincing messages tailored to executives and privileged users, often bypassing traditional email filters.

• Exploitation of Vulnerabilities: Publicly exposed systems, unpatched applications, and legacy software are common entry points. Attackers actively scan for these weaknesses, particularly in remote access infrastructure.

• Lateral Movement: Once inside a network, ransomware frequently moves laterally to escalate privileges and maximise impact. Tools like Mimikatz, Cobalt Strike, and living-off-the-land techniques enable attackers to avoid detection while expanding control.

• Credential Theft: Stolen credentials, whether through phishing, brute force, or prior breaches, remain an effective mechanism for accessing critical systems. Compromised accounts facilitate ransomware deployment and data exfiltration.

• Supply-Chain Exploits: Recent attacks demonstrate a shift towards compromising trusted third-party software or service providers. These exploits enable attackers to bypass perimeter defences and reach multiple victims indirectly.

Organisational Implications

Ransomware affects organisations beyond immediate financial losses. Security leaders must assess both tangible and intangible impacts.

• Operational Disruption: Ransomware can halt critical operations for hours or days. Healthcare systems, logistics providers, and manufacturing plants have experienced severe service outages due to encryption of operational technology (OT) and IT systems.

• Financial Exposure: Beyond ransom payments, costs include recovery, legal fees, regulatory fines, and reputational damage. Studies indicate that the total impact can be multiples of the ransom amount itself.

• Regulatory and Compliance Risks: Data exfiltration increases the likelihood of non-compliance with data protection regulations. Organisations subject to GDPR, HIPAA, or industry-specific standards may face penalties if breaches expose personal or sensitive information.

• Supply-Chain Vulnerabilities: Compromised partners or vendors can propagate risk across networks, creating cascading effects that extend beyond direct operations.

Practical Defences Against Ransomware

Mitigating ransomware requires a multi-layered approach combining prevention, detection, and response. Security teams should focus on strategies that align with organisational risk and operational realities.

1. Strengthen Endpoint and Network Defences

• Patch Management: Maintain an up-to-date inventory of systems and applications. Prioritise critical vulnerabilities with known exploits.

• Endpoint Detection and Response (EDR): Deploy solutions capable of detecting abnormal behaviour, lateral movement, and early indicators of ransomware.

• Network Segmentation: Isolate high-value assets to limit lateral propagation if a breach occurs.

2. Access Controls and Privilege Management

• Multi-Factor Authentication (MFA): Require MFA for all remote access and privileged accounts to prevent credential abuse.

• Least Privilege Policies: Restrict user permissions to essential functions only, reducing the potential impact of compromised accounts.

3. Data Backup and Recovery Planning

• Immutable Backups: Store backups in write-once, read-many (WORM) formats to prevent tampering.

• Regular Testing: Validate backup integrity and recovery procedures frequently. An untested backup plan may be unreliable during a live incident.

4. Threat Awareness and Phishing Prevention

• User Training: Conduct regular, realistic phishing simulations and security awareness programs.

• Email Security: Implement advanced email filtering, domain-based message authentication, and anomaly detection.

5. Incident Response and Playbooks

• Ransomware Playbook: Maintain a detailed response plan covering containment, eradication, communication, and recovery.

• Cross-Functional Coordination: Ensure IT, legal, and executive teams understand roles and responsibilities during an incident.

• Law Enforcement Engagement: Establish relationships with local authorities and cybersecurity agencies in advance.

6. Third-Party Risk Management

• Vendor Assessment: Evaluate supplier security posture and contractual obligations regarding cyber risk.

• Continuous Monitoring: Track vendor network and application activity to detect anomalous behaviour that could indicate compromise.

Conclusion

A proactive, risk-focused approach enables organisations to face modern ransomware threats with confidence. Leaders who combine technical controls with governance, awareness, and response planning will position their organisations to withstand attacks and recover with minimal disruption. 

They should also stay alert to evolving risks, including AI-driven attacks that automate social engineering and vulnerability exploitation, as well as emerging regulatory requirements that could affect incident response and reporting obligations.
