Under Active Attack

Executive Summary

In early 2026, the INC ransomware group, a ransomware-as-a-service (RaaS) operation active since mid-2023, intensified its attacks across various sectors, notably healthcare, education, and government entities. Utilizing double extortion tactics, INC affiliates gained initial access through spear-phishing campaigns and exploitation of vulnerabilities in external services. Once inside, they conducted internal reconnaissance using tools like NETSCAN.EXE and AnyDesk.exe, exfiltrated sensitive data, and deployed ransomware to encrypt systems, pressuring victims into paying ransoms to prevent data leaks.

This surge in INC's activities underscores the evolving ransomware landscape, where groups leverage RaaS models to scale operations rapidly. The focus on sectors with sensitive data highlights the critical need for organizations to bolster defenses against such multifaceted threats.

Why This Matters Now

The recent escalation in INC ransomware attacks, particularly targeting sectors with sensitive data, emphasizes the urgent need for organizations to enhance cybersecurity measures. The group's effective use of double extortion tactics and rapid operational scaling through the RaaS model present a significant and immediate threat to data security and operational continuity.

Frequently Asked Questions

The attacks revealed vulnerabilities in organizations' ability to detect and respond to phishing campaigns and unpatched external services, indicating gaps in compliance with standards requiring timely patch management and employee cybersecurity training.

Cloud Native Security Fabric Mitigations and ControlsCNSF

Aviatrix Zero Trust Cloud Native Security Fabric (CNSF) is pertinent to this incident as it could have significantly constrained the attacker's ability to move laterally, escalate privileges, and exfiltrate data by enforcing strict segmentation and identity-based access controls.

Initial Compromise

Control: Cloud Native Security Fabric (CNSF)

Mitigation: While initial access may still occur, CNSF would likely limit the attacker's ability to exploit these vulnerabilities to move further within the network.

Privilege Escalation

Control: Zero Trust Segmentation

Mitigation: Even with stolen credentials, CNSF would likely restrict the attacker's ability to escalate privileges across segmented network zones.

Lateral Movement

Control: East-West Traffic Security

Mitigation: CNSF would likely impede lateral movement by enforcing east-west traffic controls, reducing the attacker's ability to traverse the network.

Command & Control

Control: Multicloud Visibility & Control

Mitigation: CNSF would likely detect and constrain unauthorized command and control channels, reducing the attacker's ability to maintain persistent access.

Exfiltration

Control: Egress Security & Policy Enforcement

Mitigation: CNSF would likely restrict unauthorized data exfiltration by enforcing strict egress policies, reducing the attacker's ability to transfer data externally.

Impact (Mitigations)

While CNSF may not prevent the initial deployment of ransomware, it would likely limit the spread and impact by containing the attack within segmented network zones.

Recommended Actions

  • • Implement inline intrusion prevention systems (IPS) to detect and block exploitation attempts of known vulnerabilities.
  • • Enforce zero trust segmentation to limit lateral movement by restricting access between systems based on identity and policy.
  • • Deploy egress security and policy enforcement to monitor and control outbound traffic, preventing unauthorized data exfiltration.
  • • Utilize threat detection and anomaly response tools to identify and respond to unusual activities indicative of command and control communications.
  • • Ensure all systems are regularly updated and patched to mitigate the risk of exploitation through known vulnerabilities.
