Under Active Attack

Executive Summary

In Q2 2025, the global ransomware threat landscape saw a significant surge with the discovery of 1,702 new ransomware variants and nearly 86,000 users targeted. High-profile law enforcement actions included indictments and extraditions involving Black Kingdom, Nefilim, Ryuk, DoppelPaymer, and RobbinHood operators. Major campaigns leveraged vulnerabilities in SAP NetWeaver, Fortinet devices, and Microsoft Windows (CLFS driver), with actors like Qilin and DragonForce demonstrating adeptness in exploiting zero-days and supply chain weaknesses. Double extortion and rapid lateral movement were widely observed, affecting critical sectors worldwide, including healthcare, government, and managed service providers.

This incident underscores the advancement of ransomware attack tactics, the spread of sophisticated variants, and the persistence of threat actors despite law enforcement measures. The continued exploitation of newly discovered vulnerabilities and focus on high-revenue targets highlight the urgent need for enhanced prevention, detection, and incident response across organizations of all sizes.

Why This Matters Now

The escalation of ransomware tactics in Q2 2025, including rapid exploitation of critical vulnerabilities and resurgence of double extortion, demonstrates that organizations remain highly vulnerable. The urgent need to address lateral movement, east-west security, and multi-cloud visibility is critical as attackers shift to opportunistic, high-impact campaigns that evade traditional defenses.

Frequently Asked Questions

The incidents revealed critical gaps in east-west traffic security, lateral movement controls, encrypted traffic monitoring, and zero trust network segmentation across both cloud and on-prem environments.

Cloud Native Security Fabric Mitigations and ControlsCNSF

Applying robust Zero Trust segmentation, east-west traffic controls, inline intrusion prevention, and strong egress enforcement would have significantly limited attacker movement, data exfiltration, and the ultimate ransomware impact at every stage of the kill chain.

Initial Compromise

Control: Cloud Firewall (ACF)

Mitigation: Blocks direct access to vulnerable public services through enforced perimeter security.

Privilege Escalation

Control: Threat Detection & Anomaly Response

Mitigation: Detection and rapid alerting on abnormal privilege activity or exploitation.

Lateral Movement

Control: Zero Trust Segmentation

Mitigation: Prevents unauthorized east-west traffic and limits blast radius.

Command & Control

Control: Inline IPS (Suricata)

Mitigation: Identifies and blocks C2 traffic patterns and known malicious signatures.

Exfiltration

Control: Egress Security & Policy Enforcement

Mitigation: Stops unauthorized exfiltration using FQDN, application, and data movement controls.

Impact (Mitigations)

Centralized visibility enables rapid response and containment to limit overall damage.

Data Exposure

Potential exposure of sensitive configuration files, user credentials, and other critical data due to unauthorized access and exploitation of vulnerabilities.

Recommended Actions

  • • Enforce dynamic Zero Trust segmentation to restrict workload-to-workload and inter-region traffic, minimizing lateral movement opportunities.
  • • Deploy cloud-native firewalls and inline IPS for real-time inspection and automated enforcement of anomalous, malicious, or C2 traffic—east-west and outbound.
  • • Strengthen continuous threat detection and anomaly response to quickly identify privilege escalation and unusual access, enabling faster containment.
  • • Implement granular egress controls and FQDN/application filtering to prevent unauthorized data exfiltration and detect double extortion tactics.
  • • Centralize visibility and policy management across multicloud and hybrid environments to enable rapid incident response, scope identification, and damage limitation.
