Reports highlight cybersecurity risks at nuclear facilities around the world

Recent reports from the Nuclear Threat Initiative and Chatham House, both find that nuclear facilities in many countries are “easy targets for cyberattacks.” Among problems cited in the reports are a significant nuclear presence, few government regulations, and inadequate or corrupt oversight of nuclear facilities.

The reports highlight important issues, but are disappointing in that they provide little insight into the raw data used to draw their conclusions. Both reports talk about regulations existing in some jurisdictions and not in others, and also cite cybersecurity elements of regulations in some jurisdictions, but not others, but provide no sources. References to the regulations examined by the authors would help everyone interested in a deeper understanding access those regulations to understand them better.

The reports do highlight an important fact – for all the talk of cybersecurity vulnerabilities, many of the older reactors in the world are still controlled with analog controls, and those controls are immune to digital cybersabotage/compromise attempts. Newer reactors though, use digital controls and so are of greater concern. And even those reactors with analog controls for the reactor core may use digital controls for other aspects of the reactors, such as controls for cooling equipment. It was after all, cooling equipment that was damaged in the Fukishima tsunami, and whose failure ultimately resulted in explosions and the release of large amounts of radioactive materials.

Cyberattack tools, like any other software, continue to evolve and develop more features. As a result, cybersecurity attacks only become more sophisticated over time. What is today’s “advanced attack” is tomorrow’s script-kiddie tool. Nuclear generators should be leading the way for both physical and cybersecurity for industrial control systems. All industrial sites should be looking to the attacks of concern to nuclear generators and the defensive systems being deployed to deflect such attacks. What is of concern today to only nuclear sites will be every ICS site’s problem in only a handful of years.

Physical and cybersecurity at nuclear sites is a difficult problem. At Waterfall Security Solutions, we are proud to be part of the cybersecurity solution at nuclear generators throughout the USA, as well as in Japan, South Korea and Spain. Waterfall’s Unidirectional Security Gateways block 100 percent of network attacks originating on external networks at nuclear generators in these and other jurisdictions.

January news roundup: Ukraine power grid cyberattack illuminates risk to critical infrastructure

It’s no surprise the cyberattack on Ukraine’s power grid dominated industrial control system (ICS) cybersecurity news in January. Following the news of the power outages and subsequent discovery of malware and other signs of a purposeful network intrusion, cybersecurity experts, DHS and others have revealed alarming instances of cyberattacks, increasing vulnerabilities and lack of adequate cyberdefenses at industrial and nuclear sites, dams and other critical infrastructure. Perhaps the Ukraine attack is the wake up call the industry needs to escalate its investment in cybersecurity protections, such as Unidirectional Security Gateways. In the meantime, learn more in our roundup of these stories below.

Confirmation of a Coordinated Attack on the Ukrainian Power Grid (SANS, Jan. 9, 2016)

With all security eyes on the Ukraine’s Prykarpattyaoblenergo utility, SANS ICS concluded hackers likely caused the outage by remotely switching breakers, after installing malware that prevented technicians from detecting the intrusion. The key takeaway is that malware may have enabled the attack, but it was hackers’ remote access to critical operational networks that resulted in the outage. 

U.S. official sees more cyber attacks on industrial control systems (Reuters, Jan. 13, 2016)

While presenting at the S4x16 conference in Miami, Marty Edwards, head of the DHS ICS-CERT, cited increased Internet connectivity and associated vulnerabilities as the main reason behind the rise in cyberattacks on ICS networks. Others aren’t convinced, believing the recent Ukraine power grid attack has prompted authorities to look for signs of intrusion that may not necessarily be intentionally harmful events. From our perspective, any external intrusion – or even attempted intrusion – of ICSs is potentially harmful and should be taken seriously. Further, there is no doubt whatsoever that connecting critical infrastructure directly to the Internet or indirectly to Internet-accessible networks creates significant vulnerabilities.

Nuclear Facilities in 20 Countries May Be Easy Targets for Cyberattacks (New York Times, Jan. 14, 2016)

According to a distressing report by the Nuclear Threat Initiative, 20 nations have no apparent government regulations requiring minimal protection of nuclear power plants or atomic stockpiles against cyberattacks. The U.S. and many other countries have adopted strong security postures including physical security measures, removable device controls, and Unidirectional Security Gateways. This is standard practice in many jurisdictions and is something that should become standard worldwide for nuclear facilities.

Cybersecurity:IT vs. OT, and the Pursuit of Best Practices (Electricity Policy, January 2016)

In this article, industry experts, Paul Feldman, director of Midcontinent ISO, and Dan Hill, board member for the New York ISO, explore the new threats to our power systems. They point out that cybercriminal sophistication has outpaced the resulting regulations and urge the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC) to establish industry regulations that reflect the current threat landscape. Hill and Feldman point out that adequate, modern ICS security is very different from doing the minimum to be in compliance and recommend the use of unidirectional security gateways to eliminate the threat of remote-control and other network attacks from business networks and from the Internet.

NSA Hacking Chief: Internet of Things Security Keeps Me Up at Night (MIT Technology Review, Jan. 28, 2016)

Rob Joyce, chief of the NSA’s Tailored Access Operations unit, shook up the SCADA security community when he stated, “SCADA security is something that keeps me up at night.” Referring to the thousands of ICSs, such as power plants and other critical infrastructure, that are connected to the Internet without proper protections in place, Joyce singled out heating and cooling systems as examples that nation-state hackers can use to infiltrate control systems. He knows this to be true since these same systems are used as points of ingress by his own team. As alarming as this seems, it’s the reality we face as more and more industrial control systems are connected to the Internet.

December news roundup: Aging infrastructure and foreign hackers mark the end of 2015

December’s cybersecurity news further illustrated the reality that foreign state hackers are targeting U.S. critical infrastructure. Of greater concern is the fact that much of our infrastructure security is inadequate to protect against a targeted attack. With outdated security and the growing adoption of the Industrial Internet of Things (IIoT), power grids, dams and other critical infrastructure are at increased risk of a successful network intrusion. Will recent legislation provide the protections needed to improve cybersecurity for critical infrastructure, or is it too little, too late? Read on to learn more about the news and events that capped 2015 and set the tone for the New Year.

Cyber protection a priority for GPS (The Hill, Dec. 4, 2015)

To most, GPS is a useful technology that helps us navigate unfamiliar roads, but GPS has become the backbone of our virtual infrastructure. It is widely used in military operations and controls and provides critical timing functions to ensure control over our power infrastructure. And, according to USAF Col. Brian Searcy (ret.), our global positioning system is a prime target for cybercriminals or nation state adversaries.

House unanimously passes bill boosting resources to fight cybercrime (The Hill, Dec. 10, 2015)

The House unanimously passed a bill to provide state and local governments with federal resources to fight cybercrime. The bill would direct the Department of Homeland Security’s (DHS) cyber hub — known as the National Cybersecurity and Communications Integration Center (NCCIC) — to provide state and local governments with technical training and strategic guidance to help bolster their cyber defenses. The bill is now awaiting a vote in the Senate.

Amit Yoran’s predictions for 2016 (RSA, Dec. 11, 2015)

RSA president, Amit Yoran, shared his insights and outlook for the security landscape in 2016. Of note, Yoran believes a critical breach of an ICS network is increasingly likely to occur in 2016. As we at Waterfall have cautioned for years, many ICS security systems are inadequate to prevent against targeted cyberattacks. And now as IIoT, remote access and automated workflows gain adoption within these critical networks, they are growing increasingly vulnerable to outside attacks. And, as Yoran notes, the potential impact of bringing down a power facility or water treatment plant is an attractive proposition for those who wish to do us harm.

AP Investigation: US power grid vulnerable to foreign hacks (Dec.21, 2015)

The results of a year-long investigation by the Associated Press, underscore the very real concerns security experts have been warning about for years: foreign hackers are targeting U.S. critical infrastructures, with some success. According to the AP report, about a dozen times in the last decade, sophisticated foreign hackers have gained enough remote access to control power grid operations networks.

Former official: Iranians hacked into New York dam (CNN, Dec. 22, 2015)

According to a former official the hack of Bowman Avenue Dam near Rye Brook, New York in 2013, was a test by Iranian hackers who managed to get control of the dam’s floodgates. News of the attack highlights a growing concern among security experts about the susceptibility of infrastructure operated by outdated or retrofit technology. Until owners of critical infrastructure commit to upgrading their security posture, they will remain vulnerable to these foreign state hacker groups.

From our perspective, any legislation that moves cybersecurity preparedness forward for all industrial control networks is a good thing, but its success depends on complete support from the private sector, including privately owned critical infrastructure. Thus far, the response on the part of many executives has the cybersecurity experts at Waterfall concerned, particularly given the recent evidence that current IT-based security has been repeatedly compromised. At Waterfall, we remain dedicated to educating the market on these vulnerabilities and the dire need for hardware enforced unidirectional gateways.

November news roundup: Why the energy sector is at the heart of cybersecurity discussions

In the wake of the ISIS-perpetrated Paris attacks and cyber threats against the U.K., government agencies are stepping up cybersecurity in a bid to detect and defend their critical infrastructure against a cyberattack by ISIS or other hacker groups. At the top of that list is the energy sector. Cybersecurity leaders from several countries have stated their concerns about a cyberattack against the power grid, refineries and oil or gas pipelines, and many of these infrastructures show serious vulnerabilities. For more on these and other stories that captured our attention last month, see our news roundup below. 

DHS cybersecurity director on avoiding security vulnerabilities when connecting to the IIoT (Control Design, Nov. 12, 2015)

Marty Edwards, head of the U.S. Industrial Control Systems Cyber Emergency Response Team (ICS-CERT), recently spoke with Control Design about security vulnerabilities with IIoT. From unsecured Ethernet on system processors to using store-bought DSL routers to remotely monitor system remote facilities to BYOD, vulnerabilities are rampant. Edwards advises control systems designers to carefully weigh the advantages of connectivity against the potential risks.

Mixing ERP and production systems: Oil industry at risk, say infosec bods (TheRegister, Nov. 18, 2015) Security researchers from ERPScan described at Black Hat Europe how to hack into SAP systems and launch attacks at and take over industrial control systems in the oil and gas sector. “…insecure setups might be exploited to interfere with operational processes and lead to disruptions in production or even sabotage.” This is possible because there is a connection between the control system network and the ERP system through a firewall.

Cyberattacks on infrastructure a 'major threat,' says CSIS chief (CBCNews Canada, Nov. 19, 2015)

Michel Coulombe, director the Canadian Security Intelligence Service (CSIS), revealed his view that a cyberattack by ISIS or other extremist groups on the country's "critical infrastructure" is "a major threat;” however, others point to major gaps in Canada’s cybersecurity strategy, specifically related o critical infrastructure, such as pipelines.

Feds lack method to grade critical infrastructure cybersecurity (The Hill, Nov. 20, 2015)

According to a new report by the Government Accountability Office (GAO), of the 15 critical infrastructures examined, 12 were overseen by agencies without proper cybersecurity metrics or formal methods to essential to protect networks from cyberattacks. These findings may add fuel to the argument that critical infrastructure industries should be required to share cybersecurity data with the government.

DARPA wants early warning system for power-grid cyberattacks (NetworkWorld, Nov 24. 2015)

The Defense Advanced Research Projects Agency (DARPA) announced the development of a new system designed to support the nation’s electric grid defenses. Called Rapid Attack Detection, Isolation and Characterization (RADICS), the system will detect and automatically respond to cyberattacks on U.S. critical infrastructure. Exact details of what the RADICS system will entail were not disclosed, but the agency will hold a Proposers Day on Dec. 14 to detail it further.

If we’ve learned nothing else in this business, it’s that cyber capabilities evolve slowly. Motive, however, can change in an instant. For organizations like ISIS, motive is in strong supply and the cyberattack capabilities necessary to wreak real havoc can be bought. We cannot sit idle while ISIS or other groups plot against our most critical infrastructures. Our very way of life depends on them.
