Ransomware’s favorite target: Critical infrastructure and its industrial control systems

Ransomware’s favorite target: Critical infrastructure and its industrial control systems

  • Written by Aaron Sandeen / Dark Reading
  • 13th March 2023

National defense and security experts long predicted that future warfare would not be waged by firearms but with code designed to disable services people depend on for daily life.

In May 2021, security experts’ worst fears came true, when a ransomware attack struck the Colonial Pipeline. Gas delivery to most of the US Northeast halted almost overnight. Although systems were eventually restored, the event still lives in infamy today and reminds us of the destructive potential cyberattacks can have when levied against critical infrastructure. Since then, similar infrastructure attacks have dominated headlines across most of the world and are increasingly carried out by non-state-sponsored actors.

In our “Q2/Q3 Ransomware Index Update,” Securin (formerly Cyber Security Works) researchers mapped out the impact of ransomware on industrial control systems (ICS) deployed in critical infrastructure establishments. They identified the three most at-risk sectors: healthcare, energy, and manufacturing. Our researchers also examined 16 ransomware vulnerabilities and the bad actors who exploit them, such as Ryuk, Conti, WannaCry, and Petya. We have included a table at the end of the article with the full list of vulnerabilities and impacted vendors.

With each successful attack, ransomware groups grow bolder and target industries that can cause the most pain to exploit the crises for maximum extortion. Understanding the threat actors and their methods is the key to protecting critical industries and maintaining smooth operations.

Healthcare

Cybersecurity and Infrastructure Security Agency (CISA) advisories to healthcare providers come in the aftermath of ongoing attacks by ransomware groups such as Black Basta, Quantum, and MountLocker. The impact of unpatched critical vulnerabilities in this sector could be potentially life threatening.

Public health and healthcare systems are affected by the majority of vulnerabilities — nine out of the 16 identified — because they are dependent on other sectors for the continuity of their service delivery and operations. Philips Healthcare, a technology-based company that develops advanced visualization software for crucial imaging equipment, is the most affected vendor, clocking in eight vulnerabilities found in its IntelliSpace Portal 9.0. Vulnerabilities CVE-2017-0144 and CVE-2017-0147 should be patched immediately for their high ransomware family associations used in real-world attacks.

Energy

An attack on an energy provider can result in grid failure or inconsistent energy output to homes, commercial buildings, or other critical service providers. The energy sector is plagued by six vulnerabilities that organizations must watch, particularly those found in Schneider Electric’s products.

  • Verizon, NTT among service providers narrowing private 5G focus
    While private 5G network hype hasn’t slowed down, service providers are starting to narrow their focus as some enterprise verticals are easier to enter than others. For example, manufacturing is frequently touted as a use case for private 5G, but Omdia analysts have said manufacturing is historically slower to adopt new technology. “The verticals where companies are […]
  • Report: Technology is encouraging unprecedented collaboration in local-government organizations
    From the way people communicate to daily work norms, technology and other drivers are encouraging unprecedented collaboration in local governments, disintegrating walls that have traditionally kept organizations siloed. A new report from Deloitte predicts a number of trends within government centered around this shift. “This year, we have one overarching theme to the trends, which is […]
  • Insurance challenges to partial-autonomous-vehicle safety
    A clamp down is underway in the United States. This may be partly due to the accidents that have occurred over recent years involving Tesla vehicles that were driving on Autopilot. Some drivers have mistakenly paid the price by thinking that Autopilot means that their vehicles are fully autonomous. In fact, the system is meant […]
  • Whatever happened to the Hyperloop?
    A decade after tech billionaire Elon Musk floated the idea of building a fifth mode of transportation called the Hyperloop, the project seems to be losing momentum. Last November, an above-ground test tunnel for Hyperloop pods that sat in front of SpaceX’s Hawthorne, California facility was reportedly removed. There is no Hyperloop service in the […]
