ZeroFox Report: Manufacturing Sector Top Target for Ransomware; Qilin Group Dominates with 295 Attacks in Q2 2026

Executive Summary

According to the Q2 2026 threat intelligence report from ZeroFox, the manufacturing industry remains the most heavily targeted sector by ransomware and digital extortion (R&DE) groups. The high potential for operational disruption makes manufacturers a lucrative target. The Qilin ransomware-as-a-service (RaaS) collective has solidified its dominance, marking a full year as the most prolific R&DE group worldwide. While the total number of observed incidents (1,885) represents a slight 8.5% decrease from the previous quarter, the year-over-year figures show a dramatic 50.7% increase, indicating a long-term growth trend. The report also notes a geographic shift, with targeting in Europe growing significantly, suggesting threat actors are diversifying their victim pool.

Threat Overview

The report from ZeroFox underscores a persistent and evolving threat landscape. The manufacturing sector's vulnerability stems from its reliance on interconnected IT and Operational Technology (OT) systems, where any downtime can lead to immediate and substantial financial losses. This gives attackers significant leverage in ransom negotiations.

The Qilin group, a Russian-language RaaS operation, has been exceptionally active. Specializing in double-extortion attacks—encrypting data (T1486) and exfiltrating it for public leakage if the ransom is not paid (T1657)—Qilin primarily targets high-value organizations in critical infrastructure sectors. In Q2 2026 alone, they were linked to 295 incidents.

The top five most active groups in Q2 2026 were:

1. Qilin
2. The Gentlemen
3. DragonForce
4. Akira
5. LockBit

These five groups alone accounted for 49.5% of all global R&DE attacks, highlighting a consolidation of power among a few highly effective operations.

Technical Analysis

Ransomware groups like Qilin typically employ a multi-stage attack chain. Initial access is often gained through phishing emails (T1566), exploitation of public-facing applications (T1190), or stolen credentials purchased from initial access brokers. Once inside, they perform reconnaissance (T1087, T1082), escalate privileges (T1068), and move laterally across the network (T1021) to identify high-value data and systems. Before deploying the ransomware payload, they exfiltrate sensitive data to their own servers (T1567) to use as leverage in their double-extortion tactics. Finally, they execute the ransomware to encrypt files across the network (T1486) and inhibit system recovery by deleting backups or volume shadow copies (T1490).

Impact Assessment

The impact of these attacks on the manufacturing sector is devastating. Production lines halt, supply chains are disrupted, and financial losses mount rapidly. The double-extortion model adds the long-term risk of data leakage, which can expose intellectual property, trade secrets, employee PII, and customer data, leading to regulatory fines, lawsuits, and loss of competitive advantage. The increasing focus on Europe, which saw a 66.6% year-over-year increase in incidents, indicates that no region is safe and that these groups are actively seeking new, less-prepared targets. While North America remains the most targeted region, its declining share suggests that defenses may be improving, forcing attackers to look elsewhere.

Cyber Observables — Hunting Hints

Security teams can hunt for generic ransomware precursor activity:

Detection & Response

• Behavioral Analysis: Deploy EDR and XDR solutions that use behavioral analysis to detect ransomware activities, such as rapid file encryption, deletion of shadow copies, or disabling of security tools. This is more effective than signature-based detection against modern, polymorphic ransomware. D3FEND's D3-PA: Process Analysis is key.
• Decoy Files: Place decoy files and user accounts (honeypots/honeytokens) on file shares. Any interaction with these decoys should trigger a high-priority alert, as it indicates an attacker is performing reconnaissance. This aligns with D3-DO: Decoy Object.
• Network Segmentation Monitoring: Monitor traffic crossing network segments. An alert on a workstation from the IT network attempting to communicate with a server in the OT/ICS network on an unusual port could be an early sign of lateral movement.

Mitigation

• Offline Backups: Maintain immutable, offline, and frequently tested backups. This is the most critical defense against ransomware, as it ensures you can restore operations without paying the ransom. This is the core of D3-FR: File Restoration.
• Network Segmentation: Segment IT and OT networks to prevent a ransomware infection in the corporate environment from spreading to critical industrial control systems. This is a core tenant of D3-NI: Network Isolation.
• Patch Management: Aggressively patch internet-facing systems and applications to close the initial access vectors commonly exploited by ransomware groups. D3FEND's D3-SU: Software Update is fundamental.
• User Training: Conduct regular phishing awareness training for employees, as social engineering remains a primary initial access vector.
