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...

Operational Technology (OT) security has affected marine vessel and port operators, since both ships and industrial cranes are being digitalized and automated at a rapid pace, ushering in new types of security challenges. Ships come to shore every six months on average. Container cranes are mostly automated. Diagnostics, maintenance, upgrade and adjustments to these critical systems are done remotely, often by third-party vendor technicians. This highlights the importance of proper secure remote access management for industrial control systems (ICS).  Learn more in our Buyer's Guide for Secure Remote Access Lifecycle Management .  We at SSH Communications Security (SSH) have been pioneering security solutions that bridge the gap between IT and OT in privileged access management .

In today's rapidly evolving threat landscape, safeguarding your organization against cyberattacks is more critical than ever. Traditional penetration testing (pentesting), while effective, often falls short due to its high costs, resource requirements, and infrequent implementation. Automated internal and external network pentesting is a game-changing solution, empowering organizations to stay ahead of attackers with cost-effective, frequent, and thorough security assessments. Strengthen Your Defenses: The Role of Internal and External Pentests  Effective cybersecurity requires addressing threats from both inside and outside your organization. Automated solutions streamline this process, enabling IT teams to implement a holistic and proactive defense strategy. Internal Pentesting: Securing the Core Internal pentesting simulates an attacker operating within your network, exposing vulnerabilities such as insider threats, compromised credentials, or breaches through physical or ...

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 ...

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 ...

A high-severity security bypass vulnerability has been disclosed in Rockwell Automation ControlLogix 1756 devices that could be exploited to execute common industrial protocol ( CIP ) programming and configuration commands. The flaw, which is assigned the CVE identifier CVE-2024-6242 , carries a CVSS v3.1 score of 8.4. "A vulnerability exists in the affected products that allows a threat actor to bypass the Trusted Slot feature in a ControlLogix controller," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) said in an advisory. "If exploited on any affected module in a 1756 chassis, a threat actor could potentially execute CIP commands that modify user projects and/or device configuration on a Logix controller in the chassis." Operational technology security company Claroty, which discovered and reported the vulnerability, said it developed a technique that made it possible to bypass the trusted slot feature and send malicious commands to the pr...

Cybersecurity researchers have discovered what they say is the ninth Industrial Control Systems (ICS)-focused malware that has been used in a disruptive cyber attack targeting an energy company in the Ukrainian city of Lviv earlier this January. Industrial cybersecurity firm Dragos has dubbed the malware FrostyGoop , describing it as the first malware strain to directly use Modbus TCP communications to sabotage operational technology (OT) networks. It was discovered by the company in April 2024. "FrostyGoop is an ICS-specific malware written in Golang that can interact directly with Industrial Control Systems (ICS) using Modbus TCP over port 502," researchers Kyle O'Meara, Magpie (Mark) Graham, and Carolyn Ahlers said in a technical report shared with The Hacker News. It's believed that the malware, mainly designed to target Windows systems, has been used to target ENCO controllers with TCP port 502 exposed to the internet. It has not been tied to any previously...

Multiple security flaws have been disclosed in Emerson Rosemount gas chromatographs that could be exploited by malicious actors to obtain sensitive information, induce a denial-of-service (DoS) condition, and even execute arbitrary commands. The flaws impact GC370XA, GC700XA, and GC1500XA and reside in versions 4.1.5 and prior. According to operational technology (OT) security firm Claroty, the vulnerabilities include two command injection flaws and two separate authentication and authorization vulnerabilities that could be weaponized by unauthenticated attackers to perform a wide range of malicious actions ranging from authentication bypass to command injection. "Successful exploitation of these vulnerabilities could allow an unauthenticated attacker with network access to run arbitrary commands, access sensitive information, cause a denial-of-service condition, and bypass authentication to acquire admin capabilities," the U.S. Cybersecurity and Infrastructure Security ...

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 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...

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...

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. Figure 1 Th...

Multiple security vulnerabilities have been disclosed in Bosch BCC100 thermostats and Rexroth NXA015S-36V-B smart nutrunners that, if successfully exploited, could allow attackers to execute arbitrary code on affected systems. Romanian cybersecurity firm Bitdefender, which  discovered  the flaw in Bosch BCC100 thermostats last August, said the issue could be weaponized by an attacker to alter the device firmware and implant a rogue version. Tracked as  CVE-2023-49722  (CVSS score: 8.3), the high-severity vulnerability was addressed by Bosch in November 2023. "A network port 8899 is always open in BCC101/BCC102/BCC50 thermostat products, which allows an unauthenticated connection from a local WiFi network," the company  said  in an advisory. The issue, at its core, impacts the WiFi microcontroller that acts as a network gateway for the thermostat's logic microcontroller. By exploiting the flaw, an attacker could send commands to the thermostat, includ...
