Summary Points
- INC ransomware has evolved from a newcomer to a major global threat in 2023, with over 800 victims across various industries, including healthcare, education, and manufacturing, by employing a Ransomware-as-a-Service model.
- The group’s technical upgrades include fully rewriting Windows and Linux/ESXi encryptors in Rust, enhancing cross-platform functionality and making detection more difficult.
- INC relies on double extortion, combining data encryption with threats to leak stolen information, increasing pressure on victims to pay ransoms quickly.
- Recent advancements involve sophisticated lateral movement tactics using legitimate remote tools, updated credential theft methods, and the spreading of related ransomware families like Lynx and Knoba, indicating a mature and expanding operation.
The Issue
INC ransomware has swiftly evolved from an emerging threat to one of the most formidable cybercriminal operations globally. Beginning as a small group in mid-2023, it has since claimed over 800 victims across various industries, including healthcare, education, legal services, manufacturing, construction, and technology. Its growth is fueled by a Ransomware-as-a-Service model, which recruits affiliates and provides sophisticated, ready-to-use tools. Recent technical upgrades, such as rewriting its encryptors in Rust for both Windows and Linux/ESXi environments, demonstrate INC’s long-term investment in cross-platform attack capabilities. These updates, coupled with enhanced credential theft tools and an affiliate program that lowers entry barriers, have made its attacks more efficient and harder to detect. The group employs double extortion tactics—encrypting files and threatening to leak stolen data—exposing victims to operational disruptions and legal or reputational damages. Security experts at Acronis, who monitor these developments, report that the malware’s infrastructure has matured significantly, and that its source code’s influence persists in related ransomware families like Lynx and Knoba, underscoring the widespread impact of INC’s evolving techniques.
Furthermore, INC’s toolkit now includes advanced methods such as leveraging legitimate remote access utilities (e.g., AnyDesk, TeamViewer) to evade detection, and exploiting vulnerabilities like CVE-2023-3519 for initial access. The group’s use of Rust-based payloads enhances its resilience and complicates analysis. Security analysts worldwide are reporting ongoing incidents, emphasizing the importance of robust cybersecurity practices; these include multi-factor authentication, patching vulnerabilities, and maintaining offline backups. In summary, INC’s rapid technical advancement, strategic targeting of high-pressure industries, and the broad dissemination of its codebase—and the associated risks—are why it remains a formidable adversary in today’s cyber threat landscape.
Critical Concerns
The issue of INC ransomware, which now uses Rust-based encryptors on Windows and Linux/ESXi systems, poses a serious threat to any business. Because Rust allows for faster, more efficient ransomware, attackers can launch attacks more quickly and effectively. Once infected, your business could face encrypted files, operational shutdowns, and data loss. Consequently, productivity drops, customer trust erodes, and revenue suffers. Additionally, recovery costs skyrocket, and your reputation might be permanently damaged. Therefore, any business—large or small—must stay vigilant and invest in robust cybersecurity defenses to prevent such devastating attacks.
Possible Action Plan
In the rapidly evolving landscape of cybersecurity threats, swift action is crucial to minimize damage and restore systems efficiently.
Rapid Response

- Forensic Investigation: Collect and analyze logs to determine entry points and attack vectors.
Containment & Eradication
- Remove Malware: Utilize specialized tools to eliminate ransomware encryptors.
- Patch Vulnerabilities: Update Windows, Linux, and ESXi systems to fix exploited vulnerabilities.
Restoration & Recovery
- Restore from Backups: Use clean backups to recover encrypted data, ensuring backups are verified.
- System Hardening: Strengthen security measures, including access controls and endpoint protections.
Communication & Reporting
- Notify Stakeholders: Inform relevant internal and external parties promptly.
- Legal & Regulatory Compliance: Report incidents according to applicable laws and regulations.
Review & Improve
- Post-Incident Analysis: Conduct lessons-learned reviews to identify gaps.
- Enhance Detection: Invest in advanced threat detection capabilities to recognize future threats proactively.
