Executive Summary

Ransomware gangs are disrupting industrial production by targeting IT systems that support industrial environments, even without gaining direct access to industrial control systems (ICS). In Q2 2026, 1,140 ransomware incidents were reported, with manufacturing accounting for 747 incidents. The severity level of this threat is high.

Technical Analysis

The threat actors are using ransomware attacks to disrupt industrial production. They do not need direct access to ICS to cause interruptions. The attacks are targeting IT systems that support industrial environments, which can lead to production disruptions.

How It Gets Exploited

An attacker gains access to an industrial organization's IT systems, often through phishing or exploitation of vulnerabilities. Once inside, they deploy ransomware, which encrypts critical files and disrupts operations. The attacker then demands a ransom in exchange for the decryption key. In this scenario, the attacker does not need to gain access to ICS to disrupt production; disrupting IT systems is enough.

Impact Assessment

The impact of these attacks is significant, with 1,140 ransomware incidents reported in Q2 2026, up 12% from Q1. Manufacturing accounted for 747 incidents. The blast radius is large, affecting industrial organizations and disrupting production.

Recommended Actions

To mitigate this threat, security teams should:
  • Prioritize protecting IT systems that support industrial environments
  • Implement robust security measures, such as backups, incident response plans, and employee training
  • Monitor for suspicious activity and detect potential ransomware attacks early
  • Keep software and systems up-to-date with the latest security patches
