One of the most notorious ransomware incidents in history happened in May 2021, when malicious hackers held the Colonial Pipeline hostage, causing gas shortages and widespread panic. The high-profile incident underscored the vulnerability of U.S. critical infrastructure and operational technology (OT) to cyberattacks.

Today, OT -- which we rely on for water, transportation, food, electricity and more -- faces escalating threats. According to recent research from Fortinet, 82% of organizations saw intrusions affect their OT systems in the past year, an increase from 73% in 2024 and 49% in 2023.

This week's featured articles explore the global financial stakes of OT security, vulnerabilities opening critical infrastructure to attack and new guidance from the federal government for securing OT assets.
