Manufacturing sector records highest industrial control system attack rate despite 56% drop in intrusion attempts: SonicWall report
The manufacturing sector recorded the highest industrial control system (SCADA) attack detection rate among industries tracked by SonicWall in the first half of 2026, even as overall intrusion prevention events declined 56.2% year on year, according to the company’s latest threat report.
The 2026 Manufacturing Protect Brief, based on telemetry from more than one million security sensors, found that manufacturers continue to face targeted cyberattacks as operational technology (OT) becomes increasingly connected to enterprise IT environments.
While intrusion prevention system (IPS) detections fell to 474 million events during the first half of the year, SonicWall said the decline reflects more targeted attack strategies rather than lower cyber risk.
The report identified the Hikvision IP Camera Command Injection vulnerability (CVE-2021-36260) as the most prevalent IoT attack signature, generating 43 million detection events across manufacturing networks. Overall, IoT attacks accounted for 46.2 million detections, with more than half of manufacturing organisations recording...
