Industrial Control Systems (ICS) Face New Ransomware Concern

Dragos is a company that provides industrial asset identification, threat detection, and response to help organizations stay ahead of adversaries. According to Dragos intelligence and threat reports, it appears that a segment of code called Snake or EKANS, first recognized in December, 2019, has been designed as ransomware to target Windows systems used in industrial control systems (ICS). 

Ransomware is malicious software that will lock up data on a computer’s drive, then travel across the network and encrypt other data. The saboteurs will then demand payment in exchange for releasing the data. Whereas industrial control system machines are high-value targets (healthcare is the other high-value target) EKANS is unusual in that the malicious code uses targeted intelligence for control systems to first encrypt the root data (files are encrypted and renamed with random 5-character extension) and then ruin the software processes and hold the data hostage.

EKANS targeted companies and are sent a ransom note with the instruction to pay the ransom in cryptocurrency. There is an email address provided for contact/replies.

Manufacturing plants, power grids, and industrial concerns (such as oil refineries) are all targets of this malicious malware.

Another feature of the EKANS ransomware is it is programed to terminate sixty-four (64) various processes on computers – most of which are ICS specific.  This suggests the possibility that the EKANS may also share features similar to the Megacortex ransomware, which first appeared in early 2019.  Megacortex relies on a manual method of deployment rather than self propagation ransomware deployment.

It is still unknown whether the EKANS ransomware originated from state-sponsored hackers or via real cybercriminals trying to profit from industrial control system owners. It appears that it may be the latter, based on the most recent analysis of the nature of the ransomware – analysis by Dragos researchers.

It is wise to raise awareness with among everyone who touches your systems and it would be prudent to have someone within your organization (or a consultant) tasked with keeping data security protections current.  In addition, it is crucial to have ICS organizations rethink their cybersecurity leadership philosophy. In many organizations, the evangelists for cybersecurity are not equipped to exert influence in the company.  Cybersecurity is still treated as a back-office job, but it needs to be treated as priority by the organizational leaders.

Dragos adversary hunters recommend keeping ICS systems segmented from the rest of the network. In this way, if just one Window machine is infected, the virus can’t mobilize to the systems that control the infrastructure. In addition, standard practices such as backups, stored offline, and including the last known good configuration data will somewhat reduce the liability of slow recovery. Guardrails such as improved access and mechanisms for authentication will also help to reduce the risk of these increasingly troubling attacks on ICS systems.

Reducing Material Waste in Flexible Pet (Polyethylene Terephthalate) Production

Polyester is very popular because it is a light, soft, flexible, low-maintenance material that keeps you warm. Making it this way poses diverse challenges to PET producers.

A chemical plant specializing in producing PET was looking for a solution to reduce the waste resulting from product variance. The factory produces 25,000 tons of polyester annually, which is then provided to other manufacturers to produce a vast range of end products.

The SITRANS FC430
monitors the glycol flow.

This vast range requires different PET grades, which are achieved by slight variations in the synthesis procedures. In order to investigate possible options to upgrade their primary processing, understanding the complete process is vital. In the case of PET production, this process starts with mixing three key ingredients – PTA and IPA powder along with glycol liquid – in specific ratios to make a paste.

These source materials are stored in stainless steel bins with a volume of 2649 ft3. Rotary feeders move the mate- rial from these bins to a batching vessel along with glycol to make the polyester paste. The batching vessel is agitated to ensure that the mixture is always consistent. Monitoring tank levels, precisely controlling the dosing, the efficient use of raw materials and ensuring a consistent mix are the key parameters

SIWAREX WP251

when it comes to improving the primary processing. When Siemens designed a new system for the chemical plant from the bottom up, the Siemens S7-1200 PLC controller was the first product that was installed to set up a compact and flexible automation solution, which keeps track of the key parameters and the process efficiency.

Don’t get mixed up during mixing

Each raw material bin is mounted on Siwarex WL280 ring torsion load cells to achieve optimum weighing accuracy. These load cells are connected to two Siwarex WP251 weighing modules, which are specifically designed for batching applications. The advantages of this solution are that the WL280 load cells feature a C3 class rating for accuracy as well as an IP68 rating for protection against dust and direct high-pressure cleaning – ideal for handling powder materials such as PTA. In connection with the Siwarex WP251, a customer-specific application was engineered with a resolution of up to +/- 4 million parts.

SITRANS TS500

The glycol as the liquid component in this process is monitored by a Sitrans FC430 coriolis mass flowmeter providing a 4-20 mA output, which varies based on the flow rate of the material. This signal is fed into an analog S7-1200 input module. A Sipart PS2 positioner controls the valves to regulate the flow rate. In such flexible processes as this one, the operator individually sets the setpoint for total production. At the field level, this flexibility is achieved using Sinamics variable frequency drives, which independently adjust the flow rate of each material. To close the loop, the discharge rates from the raw material bins are monitored by the WP251. The output is then processed by the S7-1200 controller, sent through an analog module to control the Sipart PS2 positioner – which in turn allows more or less glycol to flow into the batching vessel. The downstream Sitrans FC430 flow meter additionally verifies the flow rate to ensure a high-quality mix.

How powder and liquid become PET

Pointek CLS200

The temperature of the paste is another crucial factor when it comes to producing high-quality PET. If the agitation causes too much heat, the whole mixture could be lost, causing unwanted waste. In this configuration, a TS500 controls the temperature to the optimum level. To further cut down on product loss, a Pointek CLS200 capacitance- based switch acts as a backup device to ensure that the material discharges completely, and does not build up or overflow. Its high frequency oscillation makes it insensitive to product buildup, therefore guaranteeing reliable level monitoring in the PET paste vessel. For integrated control and alarm management, the level switch is connected to the S7-1200 controller. With 13 sensors, 2 VFDs, 3 geared motors, 4 modules and 1 HMI installed and connected to the control system, the plant managers reap the benefits of a comprehensive portfolio from one supplier. The new equipment is reliable and efficient and – together with the DCS solution – offers excellent process and data control.

Less material waste and reduced downtimes

SIPART PS2

Where did this leave the chemical company? After the equipment had been running for 3 months, the first estimates were made as to whether the initial goals of reduced waste and increased efficiency had been met. The result: plant efficiency had increased by 27 % due to the reduced material waste and product loss. Further, the more reliable process measurements and diagnostics help the company to service their equipment on a preventive basis instead of a reactive one, resulting in reduced downtimes and in- creased reliability.

Simplified diagram showing the customer’s process.

So the next time, you put on your running gear, take a sip out of a plastic bottle or attach your safety belt, maybe you will remember the effort that goes into producing the PET that is needed to manufacture these types of products. By the way – they have another important characteristic in common as they can be completely recycled.

What Are Pneumatic Actuators?

Internal view of rack and pinion actuator
(Flowserve Worcester)

Pneumatic valve actuators are used in extreme conditions in many industries such as oil and gas, chemical, water and wastewater, bulk storage, pulp & paper, and power generation. These devices are used in a multitude of valve control processes for regulation (or cessation) of flow, controlling pressure and adjusting level.  Due to their reliability and simplicity, pneumatic actuators are one of the most popular types of actuators used in industry today.

Pneumatic valve actuators work by conversion of air pressure into motion. The device applies a force of air to a diaphragm, rotary vane, or piston that is attached to the actuator shaft, which is then mechanically connected to the stem of the valve or damper. Depending on the type, pneumatic actuators produce either linear or rotary motion. 

ACTUATOR ACTION - SPRING RETURN OR DOUBLE ACTING

Spring Return — Pneumatic actuators with spring return design have air supplied from one side. The spring on the opposite side is responsible for the motion. With this design, air compression moves the opens or shuts the valves while the spring is responsible for the opposite motion. 

Double Acting  — Double acting actuators have air fed on both sides of a piston. The pressure on one side is higher as compared to the other that results in the required in movement. Air is used to open and close the valves.  

Diaphragm actuator
(Samson)

PNEUMATIC ACTUATOR DESIGNS

Diaphragm Actuators — Diaphragm actuators work by applying pressure to a thin membrane or diaphragm. 

Piston Actuators — Piston actuators apply compress air to a piston that is within a cylinder. Air is fed into a chamber that moves the piston in one direction. The piston moves in the opposite direction when air pressure is removed (spring assisted) or directed to the other side (double acting). 

Rack and Pinion — Rack and pinion actuators produce rotation by applying pressure to pistons with gears that turn a pinion gear. Rack and pinion actuators can be spring return or double acting. They are valued because of their compact size and versatility.

Scotch Yoke — A scotch-yoke actuator contains a piston, yoke, connecting shaft, and rotary pin.

Scotch yoke actuator
(Samson)

They can be direct acting or spring return. They are capable of providing very high torque outputs and are generally used on larger valves. Scotch yoke actuators can be powered by air or process gas.

Rotary Vane —Vane actuators use a mechanical vane, connected to a shaft, that separates a circular shaped body in two "clamshell" halves. The vane moves in response to the differential pressure inside the actuator body, turning the shaft clockwise or counter-clockwise in response to the pressure differential. External springs units are available for spring return models.

BENEFITS OF PNEUMATIC ACTUATORS

The use of compressed air (typically found in all industrial facilities) as the power source is the prime advantage for the use of pneumatic actuators. Additionally, pneumatic actuators have an advantage in suitability for different environments and can be used in extremes temperatures. They are preferred over electrical actuators in explosive, flammable and other hazardous areas because they do not require electricity (a possible ignition source) to operate. They do not create electrical fields or electrical noise since there is no electrical motor. Pneumatic valve actuators are faster opening and closing compared to their electric counterparts. Finally, they are low cost, lightweight, durable, require little maintenance (depending on quality) and there are a myriad of positioning controls, speed controls, and communications devices available for tailoring the actuator to the application.

DRAWBACKS OF PNEUMATIC ACTUATORS

While compressed air is the main reason for using pneumatic actuators, it can also be considered a drawback. For instance, pneumatic actuators can perform poorly when the air supply source is located at a distance, resulting in lag and slow response. Another drawback of pneumatic actuators is the additional cost for the compressed air system due to the requirement of dust filters and moisture removing dryers. These are required to ensure clean air is fed into the system.

APPLYING PNEUMATIC ACTUATORS

There are many aspects to the proper, safe, and efficient application of pneumatic actuators to valves and dampers. Sizing the power output (torque) being paramount. All valves and dampers have unique torque requirements. You must consider a threshold force for opening (breakaway), as the valve continues to move to its open or closed position, and then for seating. Matching the actuators to the valve type, and operating conditions is critical. Published torque curves must be reviewed and understood. Too little torque and the vale will not respond. Too much torque increases cost and can damage the valve. Spring return adds to this complexity. Considering all this, it is strongly suggested you always discuss any valve actuation requirement with an experienced applications expert. They will ensure the proper, safe, and cost effective mating of pneumatic actuator to valve or damper.

What Is IIOT? Understanding Industrial IoT and the Technology Behind It

IoT or the internet of things needs no introduction. However, you may want to familiarize yourself with its offshoots such as the Industrial IoT, better known as IIoT. The simplest way to define IIoT would be the implementation of IoT capabilities in an industrial or manufacturing setting.

An amalgamation of various technologies such as big data, machine learning, automation, and sensor data, industrial IoT enables a connected enterprise by combing the information and operational department of the industry. Let’s take a more detailed look at IIoT and the technology behind it.

Understanding IoT

A sector that is rapidly progressing and accounts for a major share in the global IoT spending, IIoT provides manufacturers and industrialists with a significant opportunity to not only monitor but also automate many complex manufacturing/industrial processes. IIoT, a network of connected devices, enables systems to collect, track, disseminate, and analyze valuable new insights.

With these insights, industrial companies can make smarter, faster business decisions. By changing how industries work, IIoT is transforming them. Additionally, businesses are getting desired outcomes by integrating IIoT with other technological solutions. This includes providing production data in real time to unveil additional plant capacity, stopping cyber-attacks through increased visibility or control over the industrial control systems, and allowing identification of corrosion within a refinery pipe through predictive analytics.

IIoT is driving incredible levels of efficiency, productivity, and performance by combining technology, industrial big data analytics, cyber security, and machine-to-machine (M2M) communication. And, this has helped bring transformative operational and financial benefits to companies in the healthcare, aviation, manufacturing, oil & gas and power & energy sectors.

The Future of IIOT

It is predicted that the industrial internet could be worth over $200 billion by 2030. This is the reasons many companies have invested heavily in the industrial internet. Example of this is the Industrial Internet Consortium—an association founded companies to accelerate the development, adoption, and widespread use of interconnected people, machines and devices and intelligent analytics.

SIEMENS is helping drive the industrial transformation by leveraging the potential of the industrial internet. The company predicts that in the future, IIoT will account for a major share of the global economy and will impact both energy production and energy consumption. Today, industries are making all sorts of efforts to modernize systems and equipment to meet new regulations, keep up with increasing speed and volatility of the market and deal with disruptive technologies.

Significant improvements to efficiency, safety, and profitability have been experienced by businesses that have embraced IIoT and this trend is expected to continue in the future as IoT technologies are more widely adopted.

White Paper: Breakthrough Solenoid Valve Technology for Upstream Oil and Gas Heating Equipment

Low-temperature stainless steel fuel shutoff valves are usually utilized for on/off control of fuel gas
within gas fuel trains in process heating system burners. These systems are widely used by oil and gas firms as well by as original equipment manufacturers (OEMs) that produce gas heating equipment or burner management systems (BMSs) and controls in upstream oil and gas pipelines and tanks.

In recent years, a new generation of solenoid valve technology has been changing the shutoff valve game. Their modern designs provide pipeline and tank heating systems with robust, durable performance; safety; and regulatory compliance — all while increasing efficiency and productivity.

Many operators in North America and beyond are moving away from using pneumatically operated shutoff valves on their pipelines and tank heaters. They’re replacing them instead with valves introduced within the last decade by a few manufacturers — all based on solenoid shutoff valve technologies. White paper courtesy of ASCO.

Understanding HART Communication Protocol

A technological advance introduced in the late 1980’s was HART, an acronym standing for Highway Addressable Remote Transmitter. The purpose of the HART standard was to create a way for instruments to digitally communicate with one another over the same two wires used to convey a 4-20 mA analog instrument signal. In other words, HART is a hybrid communication standard, with one variable (channel) of information communicated by the analog value of a 4-20 mA DC signal, and another channel for digital communication whereby many other variables could be communicated using pulses of current to represent binary bit values of 0 and 1. Those digital current pulses are superimposed upon the analog DC current signal, such that the same two wires carry both analog and digital data simultaneously.

Looking at a standard loop-powered (2-wire) process transmitter circuit, we see the transmitter, a DC power supply (voltage source), and usually a 250 ohm resistor to create a 1 to 5 volt signal readable by any voltage-sensing indicator, controller, or recorder:

The transmitter’s primary function in this circuit is to regulate current to a value representative of the measured process variable (e.g. pressure, temperature, flow, etc.) using a range of 4 to 20 mA, while the DC voltage source provides power for the transmitter to operate. Loop-powered instruments are very common in industrial instrumentation because they allow both power and (analog) data to be conveyed on the same pair of wires.

With the advent of microprocessor-based process transmitters, it became possible for instrument technicians to digitally configure parameters inside the transmitter (e.g. range values, damping values) and also query the transmitter for self-diagnostic alarms. In order to make full use of this digital functionality, though, there had to be some way to communicate digital data to and from the process transmitter over the same two wires used to convey the 4-20 mA analog signal. Otherwise, the only way to access this rich array of digital data inside the transmitter would be to connect a communicator device to some data port located on the transmitter itself, which is inconvenient due to the nature of how these transmitters are used in industry (located in dirty places, often hard to access while carrying a personal computer or other communication device).

Thus the HART communication protocol was born to address this need. HART communicates digital data along the loop conductors in the form of AC signals (audio-frequency tones) superimposed on the 4-20 mA DC current signal. A modem built into the smart transmitter translates these AC signals into binary bits, and vice-versa. Now, instrument technicians could “talk” with the new microprocessor-based transmitters simply by connecting a HART communications device at any point along the two-wire cable, even at the far end where the cable terminates at the control system hardware (panel-mounted controller, PLC, DCS, etc.).

Being able to communicate digital data over the same wire pair as the DC power and analog signal opens a whole new range of possibilities. Now, the field-mounted transmitter can communicate self-diagnostic information, status reports, alarms, and even multiple process variables to the control system in addition to the original analog signal representing the (main) process variable. With digital communication, the only data limitation is speed (data rate), not quantity. The control system may even communicate information to the transmitter using the same digital protocol, using this digital data channel to switch between different measurement range sets, activating special features (e.g. square-root characterization, damping, etc.), automatically and remotely.
