Summary
Microsoft has highlighted the urgent need to secure internet-exposed operational technology (OT) devices following a rise in cyber attacks since late 2023. Such attacks can manipulate critical parameters in industrial processes, potentially causing malfunctions and outages. OT systems' vulnerabilities are often due to weak passwords and outdated software, making them easy targets. Recent advisories from Rockwell Automation and the U.S. Cybersecurity and Infrastructure Security Agency (CISA) stress the heightened risk amidst geopolitical tensions, with pro-Russia hacktivists targeting control systems in North America and Europe. To mitigate these risks, organizations are urged to enhance their OT security hygiene, reduce attack surfaces, and implement zero trust practices. Additionally, Claroty has reported on Fuxnet, a new malware used to attack Russian infrastructure, highlighting the evolving threat landscape for OT systems.
