Researchers fight cybercrime with new digital forensic tools and techniques

Irfan Ahmed, Ph.D., associate professor of computer science, provides digital forensic tools — and the knowledge to use them — to the good guys fighting the never-ending cyber-security war. Ahmed is director of the Security and Forensics Engineering (SAFE) Lab within the Department of Computer Science and VCU Engineering. He leads a pair of interrelated projects funded by the U.S. Department of Homeland Security (DHS) aimed at keeping important industrial systems safe from the bad guys — and shows the same tools crafted for investigating cyber attacks can be used to probe other crimes. The goal of cyber attacks on physical infrastructure may be to cause chaos by disrupting systems and/or to hold systems for ransom. The SAFE lab focuses on protecting industrial control systems used in the operation of nuclear plants, dams, electricity delivery systems and a wide range of other elements of critical infrastructure in the U.S. The problem isn’t new: In 2010, the Stuxnet computer worm targeted centrifuges at Iranian nuclear facilities before getting loose and infecting “innocent” computers around the world. Cyber attacks often target a portion of the software architecture known as the control logic. Control logic is vulnerable in that one of its functions is to receive instructions from the user and hand them off to be executed by a programmable logic controller. For instance, the control logic monitoring a natural gas pipeline might be programmed to open a valve if the system detects pressure getting too high. Programmers can modify the control logic — but so can attackers. One of Ahmed’s DHS-supported projects, called “Digital Forensic Tools and Techniques for Investigating Control Logic Attacks in Industrial Control Systems,” allows him to craft devices and techniques that cyber detectives can use in their investigations of attacks on sensitive critical infrastructure. Their investigation capabilities, he explains, is an under-researched area, as most of the emphasis to date has been on the prevention and detection of their cyber attacks. “The best scenario is to prevent the attacks on industrial systems,” Ahmed said. “But if an attack does happen, then what? This is where we try to fill the gap at VCU. And the knowledge that we gain in a cyber attack investigation can further help us to detect or even prevent similar attacks.” In the cat-and-mouse world of cyber security, the way cybercriminals work is in constant evolution, and Ahmed’s SAFE lab pays close attention to the latest developments by malefactors. For instance, an attacker may go for a more subtle approach than modifying the original control logic. An attack method called return-oriented programming sees the malefactor using the existing control logic code, but artfully switching the execution sequence of the code. Other attackers might insert their malware into another area of the controller, programmed to run undetected until it can replace the function of the original control logic. Attackers are always coming up with new methods, but each attack leaves evidence behind. The SAFE lab examines possible attack scenarios through simulations. Scale models of physical systems, including an elevator and a belt conveyor system, are housed at the SAFE lab to help facilitate this. The elevator is a four-floor model with inside and outside buttons feeding into a programmable logic controller. The conveyor belt is more advanced, equipped with inductive, capacitive and photoelectric sensors and able to sort objects. The tools and methods applied in cybercrime can be useful in tracking down other malefactors. That’s where Ahmed’s second DHS-funded project comes in. It’s called “Data Science-integrated Experiential Digital Forensics Training based-on Real-world Case Studies of Cybercrime Artifacts.” Ahmed is the principal investigator, working with co-PI Kostadin Damevski, Ph.D., associate professor of computer science. The goal is to keep law enforcement personnel abreast of the latest trends in the field of cybercrime investigation and to equip them with the latest tools and techniques, including those developed in the SAFE lab. “For example, investigators often have to go through thousands of images, or emails or chats, looking for something very specific,” Ahmed said. “We believe the right data science tools can help them to narrow down that search.” The FBI and other law enforcement agencies already have dedicated cybersleuthing units; the Virginia State Police have a computer evidence recovery section in Richmond. Ahmed and Damevski are arranging sessions showing investigators how techniques from data science and machine learning can make investigations more efficient by sorting through the mounds of digital evidence that increasingly is a feature of modern crime.

Aston University bioenergy expert urges government to use COP27 to move consumers away from fossil fuel use

COP27 should be turning point to switch from heating homes with fossil fuels Professor Patricia Thornley, was a presenter at COP26 in Glasgow She believes one year on there’s not enough progress to cut emissions from homes. One of the UK’s leading bioenergy experts has said COP27 should be a turning point to help UK consumers switch from heating their homes with fossil fuels. Professor Patricia Thornley, director of Aston University’s Energy and Bioproducts Institute (EBRI), was a presenter at COP26 in Glasgow last year. She leads the UK’s national bioenergy research programme, SUPERGEN Bioenergy hub. Her research focuses on assessing the sustainability of bioenergy and low carbon fuels. Professor Thornley believes that one year on, not enough has been done to encourage the public to cut down on the emissions their homes produce. The UK has the oldest housing stock among developed countries, with 8.5 million homes being at least 60 years old. That is despite COP26’s reaffirmation of the Paris Agreement goal of moving away from fossil fuels, and the call for stronger national action plans to reduce carbon dioxide emissions. She has welcomed initiatives to help some UK industries move towards net zero, but believes householders are not getting the same support, for example with help to insulate their homes more effectively. She said: “Responses to the energy crisis in which we find ourselves have been mixed. “Government initiatives such as funding feasibility studies for hydrogen from bioenergy (turning biomass into hydrogen whilst separating and capturing the carbon portion of the biomass) and other technologies are promising.” Professor Thornley adds: “The recent price hikes in petrol and natural gas highlight the extent to which the UK relies on fossil fuels. “Unlike some areas of industry, domestic consumers have been treated differently, and recent help with energy costs is arguably subsidising us to keep emitting carbon dioxide. “A more forward-thinking approach would have been to invest in tackling the root cause of the problem by addressing home insulation.” Professor Thornley is a fellow of the Royal Academy of Engineering, and recently gave evidence to the Environmental Audit Committee about the use of sustainable timber in the UK as an alternative fossil fuel.

First Commercial-Scale Wind Farm in the U.S. Would Generate Electricity to Power 400,000 Homes

The Vineyard Wind project, located off the coast of Massachusetts, is the first major offshore wind farm in the United States. It is part of a larger push to tackle climate change, with other offshore wind projects along the East Coast under federal review. The U.S. Department of the Interior has estimated that, by the end of the decade, 2,000 turbines could be along the coast, stretching from Massachusetts to North Carolina. "While the case for offshore wind power appears to be growing due to real concerns about global warming, there are still people who fight renewable energy projects based on speculation, misinformation, climate denial and 'not in my backyard' attitudes," says Karl F. Schmidt, a professor of practice in Villanova University's College of Engineering and director of the Resilient Innovation through Sustainable Engineering (RISE) Forum. "There is overwhelming scientific evidence that use of fossil fuels for power generation is driving unprecedented levels of CO2 into our atmosphere and oceans. This causes sea level rise, increasing ocean temperature and increasing ocean acidity, all which have numerous secondary environmental, economic and social impacts." Schmidt notes that what's often missing for large capital projects like the Vineyard Wind project is a life cycle assessment (LCA), which looks at environmental impacts throughout the entire life cycle of the project, i.e., from raw material extraction, manufacturing and construction through operation and maintenance and end of life. These impacts, in terms of tons/CO2 equivalent, can then be compared with the baseline—in this case, natural gas/coal power plants. "With this comprehensive look, I suspect the LCA for an offshore wind farm would be significantly less than a fossil fuel power plant," says Prof. Schmidt. Complementing the LCA should be a thorough, holistic view encompassing the pertinent social, technological, environmental, economic and political (STEEP) aspects of the project, notes Prof. Schmidt. "This would include all views of affected stakeholders, such as residents, fishermen, local officials and labor markets. Quantifying these interdependent aspects can lead to a more informed and balanced decision-making process based on facts and data." "At Villanova's Sustainable Engineering Department, we've successfully used both the LCA and STEEP processes... for many of our RISE Forum member companies' projects," notes Prof. Schmidt.

Cheap Energy Can Be a Bridging Fuel Needed to Get to the Endpoint of Renewable Energy Sooner

Far from banning fracking, the Biden/Harris ticket appears to be allowing it if not tacitly supporting it. This is not a contradictory stance to their aggressive renewable energy policy, according to Scott Jackson, a visiting professor of chemical and biological engineering at Villanova University's College of Engineering, who previously directed the microbial enhanced oil recovery program at DuPont Corporation. "Rather, it is recognition that cheap energy—especially natural gas produced as a result of fracking—can be a bridging fuel needed to get to the end point of renewable energy sooner," Jackson says. No one can dispute that the share of our energy coming from less efficient/more polluting coal has dropped dramatically despite the current administration’s attempts at supporting the coal industry. The reason is obvious—cleaner burning energy (less CO2 emissions) from gas fired turbine generators make more economic sense. Gas fired turbine generators are economical at a smaller scale and provides an energy source that can be rapidly turned on or off at any time. This helps to counterbalance the intermittency of renewable energy and, in some sense; this has allowed greater adoption of renewable energy. The cheapest energy source on the planet is land based wind power. The market has responded to this and now renewables make up 19 percent of our electricity. This percentage was thought to be impossible just a few years ago. Wind power energy payback time (time needed to recoup the energy invested) is measured in months and not years, and investors understand this. A much greater share of renewables (wind and solar) is very doable and makes economic sense. Jackson notes that development of cheap energy storage technology will help and must be implemented once economies of scale are achieved, however, a national power grid capable of moving energy from the wind- and sun-rich Midwest to the West Coast and East Coast will improve the reliability of renewables to the point where as much as 70% of our electricity can be sourced renewably—without new storage capacity (2018 study by the National Renewable Energy Laboratory). Improvements in battery technologies and economy of scale are starting to drive down the costs of electric transportation and storage. Eventually, natural gas sourced power generation will not be competitive to renewables," notes Jackson. "Despite the current low price of gasoline, in part as a result of fracking used in oil fields, electric cars are far more economical to operate. Companies like BP, Exxon-Mobile and Shell recognize that they are energy companies and are pivoting to more renewable sources of energy. "Ultimately, our government has a responsibility to invest in the technologies of the future that make economic sense—as renewables do—and not support the more costly and outdated fossil fuel industry," says Jackson.

Proposed Fracking Ban Sent to U.S. Congress

If passed, bills introduced to the United States Congress could prevent federal agencies from issuing permits for expanded and new fracking in the country. Fracking is the use of a high-pressure fluid, being forced into a well to fracture or pulverize the rock next to a wellbore, to provide a pathway for oil and natural gas to flow and collect. "It's important for people to understand what fracking is and what it is not, and having an informed public is paramount in a democratic society," says the College of Engineering’s Scott Jackson, PhD, visiting assistant professor of chemical engineering. "There is a way to assure that oil and gas wells can be safely drilled and fracked with minimal impact on the environment." Fracking—a step in completing the installation of a gas or oil well—was first done in the 1940s as part of well stimulation in "tight" rock formations. Initially, it was done only in sandstone, not the shale that most people have heard about. "It has been used for more than 70 years prior to the shale revolution without controversy," Dr. Jackson says. Fracking and directional drilling are key technologies that have made the shale revolution possible; the ability to economically extract it has only come to fruition because of fracking and directional drilling. "The U.S. is now the world's largest producer of oil and natural gas. The shale revolution has driven the switch of electricity production from coal to a more environmentally friendly natural gas," says Dr. Jackson. Fracking has been controversial, and contentions concerning cariogenic chemicals being injected into "our fresh water" have been voiced by environmentalists, activists and the general public. Dr. Jackson says there is some basis for these statements, such as that water used in fracking has mostly undisclosed chemicals in it and that some of those chemicals may be carcinogenic. Because of this, Dr. Jackson says relaxing government oversight cannot be allowed. "Enforcing existing regulations and implementing and enforcing new regulations can only assure that oil and gas wells can be drilled and fracked safely with minimal impact on the environment."
