Energy industry vulnerable to increased cyber attacks
Critical infrastructure (CNI) sites and energy distribution facilities are under increasing attack, and interconnected systems in the energy industry increase vulnerabilities, with cyber attacks often go undetected for some time, says the report. However there are signficant challenges specifically for the industry.
Nine different attackers/malwares/techniques targeting the energy industry stand out, with spear phishing being the most common initial supply chain attack technique. Keeping a small attack surface in the energy industry is often pitched as the best way to mitigate the risk of a cyber attack but this is simply not possible. As energy companies save costs against the backdrop of lower oil prices, consolidating operations can weaken business resilience and redundancy levels. This gives rise to new, single critical points of failure, with any disruption across the supply chain potentially having increased consequences.
“Espionage and sabotage attacks against CNI organizations have increased over the years and I don’t think we have seen it all yet,” says Sami Ruohonen, Labs Threat Researcher at F-Secure.
Connecting Industrial Control Systems (ICS) to the Internet is increasing, and a considerable number of CNI systems in use today were installed and built before 24/7/365 internet connections were the norm and the advent of Stuxnet. Many Operational Technology (OT) components have built-in remote operation capabilities, but are either partly or entirely lacking in security protocols such as authentication.
Cyber security was not a realistic threat when these systems were manufactured, and legacy protocols and systems never had the built-in security controls that we take for granted today. Transitioning these systems to the Internet has opened them up to attacks from a myriad of angles.
“Critical Infrastructure due to its nature is an interesting target for a foreign nation-state, even during peacetime,” said Ruohonen.
F-Secure’s report shows a variety of different adversaries, each with their own motivations and tradecraft, constantly strive to compromise organizations that operate critical infrastructure. Attackers have more time than their targets and will take months to plan their attack and people, particularly company employees, are the weakest link in production.
While breaches are a certainty, Ruohonen advises organizations review their cyber security posture to implement latest technologies such as an endpoint detection and response (EDR) solution.
“EDR is a quick way to tremendously increase capabilities to detect and respond to advanced threats and targeted attacks which might bypass traditional endpoint solutions,” he said. “Managed EDR solutions can provide monitoring, alerting, and response to cover the needs 24/7. This means organizations’ IT teams can operate during business hours to review the detections while a specialized cybersecurity team takes care of the rest.”
