Energy infrastructure is a high-value target for cyber criminals. Attacks on critical national infrastructure (CNI) can have an outsized impact, disrupting essential services, causing nationwide instability, and generating financial gains for hackers. As geopolitical uncertainty intensifies, so does cyber espionage, making it crucial for energy companies to invest in resilient cyber security programmes, says Globaldata, a leading intelligence and productivity platform.

Ravindra Puranik, Oil and Gas Analyst at Globaldata, comments: “Energy companies depend on extensive third-party ecosystems, making supplier vulnerabilities a major cyber risk that can spread into IT and OT environments. Attacks exploiting shared vendor software (e.g., file-transfer tools) have hit major players.”

Puranik continues: “Mitigation requires stronger vendor governance, such as continuous monitoring, standards, segmentation, least privilege, audits, and joint incident response.”

Globaldata notes that digitisation and the convergence of information technology (IT) and operational technology (OT) are connecting legacy assets and modern grid technologies, expanding entry points where IT compromises can disrupt operations. Generative artificial intelligence (AI) further increases attacker speed and sophistication, shrinking defenders’ response windows.

Puranik concludes: “Oil and gas firms should invest in specialised cyber security services that provide continuous monitoring and rapid response, expert validation, and strong operational readiness. Equipment and oilfield service providers should also add product-focused services such as secure development support and security audits/certification to reduce supply chain risk and maintain customer trust.

“Cyber security is integral across the oil and gas value chain, for securing data, safeguarding asset integrity, and preventing financial losses.”
