Qilin and N0n Ransomware Groups Surge in October 2026 with 945 Victims Reported

Executive Summary

Encrygma threat intelligence analysts have observed a marked escalation in ransomware activity as of October 28, 2026. With 945 victims recorded this month, the landscape is dominated by aggressive operators such as Qilin and N0n. These groups are increasingly utilizing double-extortion tactics, exfiltrating sensitive data before deploying encryption to maximize leverage over victims.

Threat Analysis

According to Encrygma's Threat Severity Index (ETSI), the current ransomware landscape is rated at a 9/10, indicating a critical threat level. Encrygma analysts assess that the surge in activity is driven by the professionalization of Ransomware-as-a-Service (RaaS) models. The rapid emergence of new groups like Scarlettgroup and UmBra suggests a highly competitive and fragmented criminal ecosystem.

Technical Details

Encrygma threat data shows that attackers are increasingly weaponizing corporate AI tools to facilitate lateral movement and data exfiltration. Recent incidents, such as the alleged Emperador breach of AB InBev, highlight the targeting of cloud environments and PKI infrastructure. Encrygma's AI Threat Taxonomy classifies these as 'AI-Augmented Exfiltration' events, where automated agents identify and prioritize high-value data assets within compromised networks.

Attribution Assessment

Using the Encrygma Attribution Confidence Matrix, we categorize the activity of Qilin and N0n as 'High Confidence' based on consistent leak-site activity and TTP patterns. While some claims remain unverified, the volume of data exfiltrated—often including PII and internal credentials—aligns with established criminal methodologies observed by our global monitoring sensors.

Implications

The shift toward targeting critical sectors like manufacturing and professional services indicates a strategic move to disrupt supply chains. Encrygma analysts warn that the integration of AI into the ransomware kill chain significantly reduces the time-to-compromise, leaving traditional signature-based defenses increasingly ineffective against modern, adaptive threat actors.

Recommendations

Encrygma recommends that organizations implement strict identity and access management (IAM) controls, specifically focusing on securing cloud-based PKI certificates. Furthermore, we advise deploying behavioral analytics to detect the unauthorized use of internal AI agents. Organizations should prioritize offline, immutable backups to mitigate the impact of double-extortion attempts and ensure business continuity in the event of a successful breach.
