The High-Stakes Disconnect For ICS/OT Security

The High-Stakes Disconnect For ICS/OT Security

Jan 15, 2025 ICS Security / Threat Detection
Why does ICS/OT need specific controls and its own cybersecurity budget today? Because treating ICS/OT security with an IT security playbook isn't just ineffective—it's high risk. In the rapidly evolving domain of cybersecurity, the specific challenges and needs for Industrial Control Systems (ICS) and Operational Technology (OT) security distinctly stand out from traditional IT security. ICS/OT engineering systems, which power critical infrastructure such as electric power grids, oil and gas processing, heavy manufacturing, food and beverage processes, and water management facilities, require tailored cybersecurity strategies, and controls. This is due to the increasing attacks towards ICS/OT, their unique operational missions, a different risk surface than that of traditional IT networks, and the significant safety consequences from cyber incidents that impact the physical world. Critical infrastructure should be protected against today's threats to continue supporting national sa...

Iran-Linked IOCONTROL Malware Targets SCADA and Linux-Based IoT Platforms

Dec 13, 2024 IoT Security / Operational Technology
Iran-affiliated threat actors have been linked to a new custom malware that's geared toward IoT and operational technology (OT) environments in Israel and the United States. The malware has been codenamed IOCONTROL by OT cybersecurity company Claroty, highlighting its ability to attack IoT and supervisory control and data acquisition (SCADA) devices such as IP cameras, routers, programmable logic controllers (PLCs), human-machine interfaces (HMIs), firewalls, and other Linux-based IoT/OT platforms. "While the malware is believed to be custom-built by the threat actor, it seems that the malware is generic enough that it is able to run on a variety of platforms from different vendors due to its modular configuration," the company said . The development makes IOCONTROL the tenth malware family to specifically single out Industrial Control Systems (ICS) after Stuxnet, Havex, Industroyer (aka CrashOverride), Triton (aka Trisis), BlackEnergy2, Industroyer2, PIPEDREAM (a...
What Is Attack Surface Management?

What Is Attack Surface Management?

Feb 03, 2025Attack Surface Management
Attack surfaces are growing faster than security teams can keep up – to stay ahead, you need to know what's exposed and where attackers are most likely to strike. With cloud adoption dramatically increasing the ease of exposing new systems and services to the internet, prioritizing threats and managing your attack surface from an attacker's perspective has never been more important. In this guide, we look at why attack surfaces are growing and how to monitor and manage them properly with  tools like Intruder . Let's dive in. What is your attack surface? First, it's important to understand what we mean when we talk about an attack surface. An attack surface is the sum of your digital assets that are 'reachable' by an attacker – whether they are secure or vulnerable, known or unknown, in active use or not. You can also have both internal and external attack surfaces - imagine for example a malicious email attachment landing in a colleague's inbox, vs a new FTP server being...

Critical Flaws in Tank Gauge Systems Expose Gas Stations to Remote Attacks

Critical Flaws in Tank Gauge Systems Expose Gas Stations to Remote Attacks

Sep 30, 2024 Operational Technology / Network Security
Critical security vulnerabilities have been disclosed in six different Automatic Tank Gauge (ATG) systems from five manufacturers that could expose them to remote attacks. "These vulnerabilities pose significant real-world risks, as they could be exploited by malicious actors to cause widespread damage, including physical damage, environmental hazards, and economic losses," Bitsight researcher Pedro Umbelino said in a report published last week. Making matters worse, the analysis found that thousands of ATGs are exposed to the internet, making them a lucrative target for malicious actors looking to stage disruptive and destructive attacks against gas stations, hospitals, airports, military bases, and other critical infrastructure facilities. ATGs are sensor systems designed to monitor the level of a storage tank (e.g., fuel tank) over a period of time with the goal of determining leakage and parameters. Exploitation of security flaws in such systems could therefore have ...
Industrial Remote Access Tool Ewon Cosy+ Vulnerable to Root Access Attacks

Industrial Remote Access Tool Ewon Cosy+ Vulnerable to Root Access Attacks

Aug 12, 2024 Operational Technology / Network Security
Security vulnerabilities have been disclosed in the industrial remote access solution Ewon Cosy+ that could be abused to gain root privileges to the devices and stage follow-on attacks. The elevated access could then be weaponized to decrypt encrypted firmware files and encrypted data such as passwords in configuration files, and even get correctly signed X.509 VPN certificates for foreign devices to take over their VPN sessions. "This allows attackers hijacking VPN sessions which results in significant security risks against users of the Cosy+ and the adjacent industrial infrastructure," SySS GmbH security researcher Moritz Abrell said in a new analysis. The findings were presented at the DEF CON 32 conference over the weekend. Following responsible disclosure, the issues have been addressed in firmware versions 21.2s10 and 22.1s3 as part of an advisory [PDF] issued by Ewon on July 29, 2024 - CVE-2024-33892 (CVSS score: 7.4) - Information leakage through cookies ...

Microsoft Warns of Surge in Cyber Attacks Targeting Internet-Exposed OT Devices

Microsoft Warns of Surge in Cyber Attacks Targeting Internet-Exposed OT Devices

May 31, 2024 OT Security / Threat Intelligence
Microsoft has emphasized the need for securing internet-exposed operational technology (OT) devices following a spate of cyber attacks targeting such environments since late 2023. "These repeated attacks against OT devices emphasize the crucial need to improve the security posture of OT devices and prevent critical systems from becoming easy targets," the Microsoft Threat Intelligence team said . The company noted that a cyber attack on an OT system could allow malicious actors to tamper with critical parameters used in industrial processes, either programmatically via the programmable logic controller (PLC) or using the graphical controls of the human-machine interface (HMI), resulting in malfunctions and system outages. It further said that OT systems often lack adequate security mechanisms, making them ripe for exploitation by adversaries and carry out attacks that are "relatively easy to execute," a fact compounded by the additional risks introduced by direc...
Rockwell Advises Disconnecting Internet-Facing ICS Devices Amid Cyber Threats

Rockwell Advises Disconnecting Internet-Facing ICS Devices Amid Cyber Threats

May 22, 2024 ICS Security / Vulnerability
Rockwell Automation is urging its customers to disconnect all industrial control systems (ICSs) not meant to be connected to the public-facing internet to mitigate unauthorized or malicious cyber activity. The company  said  it's issuing the advisory due to "heightened geopolitical tensions and adversarial cyber activity globally." To that end, customers are required to take immediate action to determine whether they have devices that are accessible over the internet and, if so, cut off connectivity for those that are not meant to be left exposed. "Users should never configure their assets to be directly connected to the public-facing internet," Rockwell Automation further added. "Removing that connectivity as a proactive step reduces attack surface and can immediately reduce exposure to unauthorized and malicious cyber activity from external threat actors." On top of that, organizations are required to ensure that they have adopted the necessar...
Considerations for Operational Technology Cybersecurity

Considerations for Operational Technology Cybersecurity

Apr 30, 2024 Operational Technology / Cybersecurity
Operational Technology (OT)  refers to the hardware and software used to change, monitor, or control the enterprise's physical devices, processes, and events. Unlike traditional Information Technology (IT) systems, OT systems directly impact the physical world. This unique characteristic of OT brings additional cybersecurity considerations not typically present in conventional IT security architectures. The convergence of IT and OT Historically, IT and Operational Technology (OT) have operated in separate silos, each with its own set of protocols, standards, and cybersecurity measures. However, these two domains are increasingly converging with the advent of the Industrial Internet of Things (IIoT). While beneficial in terms of increased efficiency and data-driven decision-making, this convergence also exposes OT systems to the same cyber threats that IT systems face. Unique Cybersecurity Considerations for OT Real-time requirements Operational Technology systems often opera...
Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024 Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.
