NanoLock Secures Industrial Machines From Disastrous Cyber Attacks

Date:

Topics: Cybersecurity

Organizations: NanoLock

NanoLock calls itself an “embedded gatekeeper,” meaning that it’s cyber solution is embedded into a device or machine and features a strong locking mechanism that blocks modification attempts unless they are signed by a trusted authorization server.

According to Laubshtein, the company is known for its flexibility to operate in different operating system environments. “To be more clear about that, if our competitors, knows how to operate at the higher level of operating systems like Windows and Linux, we can also operate on lower [level] operating systems like Bare Metal, which is usually very sensitive to memory consumption and energy consumption,” he says. This gives the company a “huge advantage” because it can help them operate on low consumption or even batteries. Meanwhile, the company also offers a lightweight software solution, which makes it easy to operate. One of the biggest advantages of the NanoLock system is its zero trust approach.

From a ransomware perspective, manufacturers are quite exposed to time-driven critical processes, Heppenstall notes. “So, if you can cause a disruption, manufacturers are perceived to be more prone and therefore more likely to pay a ransom. Companies don’t run dual manufacturing processes.”

Feds Uncover a ‘Swiss Army Knife’ for Hacking Industrial Control Systems

Date:

Author: Andy Greenberg

Topics: cybersecurity, industrial control system

Organizations: Dragos

On Wednesday, the Department of Energy, the Cybersecurity and Infrastructure Security Agency, the NSA, and the FBI jointly released an advisory about a new hacker toolset potentially capable of meddling with a wide range of industrial control system equipment. More than any previous industrial control system hacking toolkit, the malware contains an array of components designed to disrupt or take control of the functioning of devices, including programmable logic controllers (PLCs) that are sold by Schneider Electric and OMRON and are designed to serve as the interface between traditional computers and the actuators and sensors in industrial environments. Another component of the malware is designed to target Open Platform Communications Unified Architecture (OPC UA) servers—the computers that communicate with those controllers.

Dragos says the malware has the ability to hijack target devices, disrupt or prevent operators from accessing them, permanently brick them, or even use them as a foothold to give hackers access to other parts of an industrial control system network. He notes that while the toolkit, which Dragos calls “Pipedream,” appears to specifically target Schneider Electric and OMRON PLCs, it does so by exploiting underlying software in those PLCs known as Codesys, which is used far more broadly across hundreds of other types of PLCs. This means that the malware could easily be adapted to work in almost any industrial environment. “This toolset is so big that it’s basically a free-for-all,” Caltagirone says. “There’s enough in here for everyone to worry about.”

Author: Sharon Brizinov

Topics: Cybersecurity, Programmable Logic Controller

Organizations: Claroty

Team82 and Rockwell Automation today disclosed some details about two vulnerabilities in Rockwell programmable logic controllers and engineering workstation software. CVE-2022-1161 affects numerous versions of Rockwell’s Logix Controllers and has a CVSS score of 10, the highest criticality. CVE-2022-1159 affects several versions of its Studio 5000 Logix Designer application, and has a CVSS score of 7.7, high severity. Modified code could be downloaded to a PLC, while an engineer at their workstation would see the process running as expected, reminiscent of Stuxnet and the Rogue7 attacks.

Manufacturing: Security and Resilience Start with Visibility

Author: Heather MacKenzie

Topics: cybersecurity

Organizations: Nozomi Networks

Having real-time situational awareness of your OT networks, including visibility into assets, connections, communications, protocols and more, allows you to start improving cyber resiliency. The good news is that you can automate asset inventory for manufacturing facilities, eliminate blind spots, and reveal assets that might have previously been missed.

Once you’ve got excellent visibility, you can move onto risk reduction. This requires real-time detection of vulnerabilities, threats and anomalies at both brownfield and greenfield facilities. It includes process insights that highlight threats to reliability, such as failing equipment, unusual variable values and networking communication anomalies.

Log4j Security Vulnerability Response Center

Date:

Topics: cybersecurity

Organizations: PTC

For remediation for Apache Log4j 2 CVE-2021-44228 and CVE 2021-45046, PTC recommends removing the JNDILookup.class as described in the remediation from Apache. Throughout PTC’s testing to date (December 10 to December 15, 2021) there have been no adverse impacts from using this method. PTC has not used this dynamic loading capability in our products, and the remediation should be both effective to the vulnerability and very low risk to our products. Any risk of this change is limited in scope to the logging subsystem of applications, and any resulting errors are far less significant than the exposure of this vulnerability. Customers can preemptively remediate the vulnerability while awaiting official certification to reduce their immediate exposure to this critical issue.

This cross-cutting vulnerability, which is vendor-agnostic and affects both proprietary and open-source software, will leave a wide swathe of industries exposed to remote exploitation, including electric power, water, food and beverage, manufacturing, transportation, and more. Log4j is found in popular open-source repositories used in numerous industrial applications, such as Object Linking and Embedding for Process Control (OPC) Foundation’s Unified Architecture (UA) Java Legacy. Additionally, adversaries can leverage this vulnerability in proprietary Supervisory Control and Data Acquisition (SCADA) and Energy Management Systems (EMS) which make use of Java in their codebase.

Inside the Log4j2 vulnerability (CVE-2021-44228)

Date:

Topics: cybersecurity

Organizations: Cloudflare

In 2013, in version 2.0-beta9, the Log4j package added the “JNDILookup plugin” in issue LOG4J2-313. To understand how that change creates a problem, it’s necessary to understand a little about JNDI: Java Naming and Directory Interface.

JNDI has been present in Java since the late 1990s. It is a directory service that allows a Java program to find data (in the form of a Java object) through a directory. JNDI has a number of service provider interfaces (SPIs) that enable it to use a variety of directory services. For example, SPIs exist for the CORBA COS (Common Object Service), the Java RMI (Remote Method Interface) Registry and LDAP. LDAP is a very popular directory service (the Lightweight Directory Access Protocol) and is the primary focus of CVE-2021-44228 (although other SPIs could potentially also be used).

Organizations: Nozomi Networks

This blog post from the Nozomi Networks Labs team investigates attacks against a low-power radio frequency WAN technology that is widely used in industrial IoT networks. Our research focused on the viability of discovering the transmission frequency of the IoT network, and jamming the signal to disrupt network communication. Although there are some practical limitations to the attack scenario we investigated, we clearly determined that there are potential attack vectors that should be considered as technology matures.
