2025 OT/ICS & IoT Cybersecurity Threat Landscape Report

The operational technology (OT), industrial control systems (ICS), and Internet of Things (IoT) environments that underpin manufacturing, oil & gas, and energy sectors have never been more attractive, or more vulnerable, to cyber adversaries. The attackers implemented quick transformations during 2024 by using automated IoT botnet attacks as well as targeted ransomware assaults that could infiltrate crucial networks inside 24 hours. The growth of wireless connectivity throughout plants and remote sites has generated multiple new blind spots which attackers use to conduct deauthentication attacks and modify data.

The 2025 Threat Landscape Report of Shieldworkz aggregates threat data obtained from 50,000+ honeypots and wireless sensors alongside threat intelligence partnerships and incident response engagements. The information presented in this report provides essential facts and security tactics for CISOs and plant managers and security architects to defend their systems against operational disruptions.

Why This Report Matters

The report reveals which sectors including Critical Manufacturing and Energy and Communications face the most intense ICS vulnerability attacks from newly discovered threats while showing that government agencies such as CISA released 240 advisories during last year

The report explains ransomware behavior changes and incident response readiness as well as post-attack confidence losses of 20% while presenting the actual financial consequences

The report explains how brute force SSH/Telnet attacks function as the main way attackers enter IoT networks while default credentials persistently create botnet threats.

You will learn about the present state of deauthentication attacks against wireless network segments that lack monitoring and discover practical methods to restore monitoring capabilities.

Why You Can’t Afford to Wait

Rapid Breach Timelines: Attackers now move from initial access to full network compromise in less than a day.

Widening Attack Surface: As smart sensors, edge devices, and remote access gateways proliferate, blind spots grow, often without your security team realizing it.

Evolving Adversary Tactics: From data manipulation techniques three times more prevalent than any other MITRE ATT&CK™ method, to state sponsored GPS spoofing campaigns, the threat actors are agile and well resourced.

Every hour of delay risks operational downtime, safety incidents, regulatory fines, and reputational damage.

Key Takeaways from the Report

When evaluating OT products, ensure each manufacturer explicitly supports the following features out‑of‑the‑box (not as paid add‑ons):

1

52% of organizations overhauled IT security collaboration last year, but only 30% have a formal incident response chain.

2

241 new advisories from CISA in 2024, impacting 70 vendors and prompting 619 ICS CERT vulnerability disclosures.

3

Data Manipulation reigns supreme: it was detected three times more often than any other technique across Manufacturing, Transportation, and Energy environments.

4

The wave of IoT botnets runs on default Credentials since unpatched SSH/Telnet devices serve as top targets for permanent shell based attacks.

These insights form the backbone of a security roadmap that emphasizes resilience, rapid response, and continuous visibility.
