Supply Chain Cybersecurity Concerns
The complex digital environment can create many cybersecurity risks in the supply chain.
Modern supply chains no longer merely involve physical goods; they generally encompass various digital products, including hardware, software, and services. As such, a solid security posture in both cyber and physical security is a must.
As supply chains become more complex and global, it becomes more challenging to track and secure all the different components and points of vulnerability; many of which can introduce risk to business and government operations.
As more critical systems depend on information and communication technologies (ICT) and operational technologies (OT), disruptions or attacks on those systems can have far-reaching consequences. These factors can complicate the digital environment and create new opportunities for adversaries to introduce risk into both federal government and commercial systems.
Fortunately, there are steps that your organization can take to protect your supply chains from cybersecurity threats. This article will cover various ways your organization can stay on top of the latest cybersecurity threats and vulnerabilities to protect your supply chain.
Why Cybersecurity in the Supply Chain is Important
The interconnectedness of the modern world has made it easier for hackers to gain access to sensitive data, and they often use supply chains to exploit companies. This can be due to either intentional flaws introduced into products, or poorly designed systems.
Additionally, regulators are increasingly focusing on cybersecurity, and companies that do not have a robust cyber risk management strategy may face penalties and liabilities should incidents occur.
According to Bob Kolasky, Exiger’s SVP for Critical Infrastructure and former assistant director at the Cybersecurity and Infrastructure Security Agency (CISA), “There is an imperative both from a policy landscape, a regulatory landscape, and also from a business landscape to do a better job at understanding risks and managing those risks.”
Through policy actions, such as the 2021 Cybersecurity Executive Order (EO 14028) the Biden administration has established a clear framework for how the government and private sector should work together to improve cybersecurity in government systems. Meanwhile, policymakers across the globe continue to do work on critical infrastructure and set up information-sharing systems that help organizations protect themselves from cyber threats while ensuring privacy rights are protected.
One year after the signing of the EO 14028 Kolasky is “pleased with the degree to which this executive order has driven and continues to drive activity. Not all executive orders do that.”
He adds, “This was the president in his role as CEO of the largest enterprise in the country, the US government, saying, ‘I want my CISO team, my risk team, to take cybersecurity more seriously.’ It has impacted the broader cybersecurity across the US, including state and local governments and critical infrastructure.”
Notable Supply Chain Attacks
Digital vulnerabilities in the supply chain can compromise the integrity of data and systems, which can impact the reliability of systems and the trust that users have in them. They can be used to gain access to sensitive information, intellectual property, and data.
Here are examples of supply chain vulnerabilities and attacks that can be potentially exploited through ransomware that may be amplified when supply chains are not properly secured, and a process designed to minimize risks:
- Microsoft Zero-Day Vulnerabilities: in September 2022, the IT Security community and Microsoft confirmed the investigation of Microsoft Exchange Server zero-day vulnerabilities, impacting thousands of enterprises directly and potentially millions indirectly.
- Log4Shell: A zero-day vulnerability in Log4j, a widely-used Java logging framework, was discovered in November 2021. Dubbed Log4Shell, the vulnerability affected an estimated 93% of enterprise cloud environments.
- SolarWinds Attack: In December 2020, it was discovered that SolarWinds, a major supplier of enterprise software, had been compromised by a sophisticated cyber-attack. The attackers could insert malicious code into SolarWinds’ software updates, which were then pushed out to SolarWinds’ customers. The attackers used this access to gain information about SolarWinds’ customers, including many government agencies.
- Section 889 devices from China: In August 2019, the US government issued an order banning the use of Section 889 devices from China. Section 889 devices are devices manufactured by “communications equipment manufactured or provided by certain Chinese entities” or vendors such as Huawei and Hikvision. This regulation was put in place because of the risk that these devices could be used to spy on or disrupt US communications networks. These devices are still exposed, potentially leading to risk and intrusion into various organizations.
- WannaCry: In May 2017, a ransomware attack known as WannaCry spread across the globe, affecting more than 230,000 computers in 150 countries. The attack took advantage of a vulnerability in Microsoft’s Windows operating system. The WannaCry attack highlighted the importance of patch management and staying up-to-date on software updates.
- Accellion: In December 2020, it was discovered that a cyber attack compromised Accellion’s file-sharing software. The attackers were able to access customer data, including sensitive information.
The Vulnerabilities that Adversaries Target in Supply Chains
Adversaries are constantly lurking—seeking vulnerabilities in your supply chain that could be exploited to gain access to networks, data, or weaknesses that could lead to disruptions in service or the failure of critical systems. They may also seek to identify and exploit relationships with key suppliers to access sensitive data or systems.
By understanding the types of risks that adversaries are targeting, organizations can better protect their supply chains and ensure that their systems are not compromised.
Exploitable Vulnerabilities in the Attack Surface
One of the main ways that adversaries can gain access to networks and information is by exploiting vulnerabilities in the attack surface.
The Computer Security Resource Center (CSRC) defines an “attack surface” as “the set of points on the boundary of a system, a system element, or an environment where an attacker can try to enter, cause an effect on, or extract data from.”
Keeping the attack surface as minimal as possible is crucial to protecting your organization from cyber supply chain attacks. By understanding the attack surface, organizations can work to patch up any vulnerabilities that an attacker could exploit which present an undue risk to the system. This is important in preventing supply chain attacks, making it more difficult for adversaries to find a way in.
Attack Vector Ransomware
Kolasky previously served as an Assistant Director at the Cybersecurity and Infrastructure Security Agency where his work found that “in each of the six phases of the ICT supply chain software life cycle, the software is at risk of malicious or inadvertent introduction of vulnerability.”
While ransomware attacks are often conducted by criminal gangs for financial gain, there is a concerning trend of ransomware attacks being led by criminal gangs that are sponsored or backed by adversarial governments, to infiltrate software at key points of vulnerability.
These groups have access to more sophisticated and destructive malware tools and often target national governments and critical infrastructure. In addition to causing financial damage, these ransomware attacks can also disrupt critical operations and cause serious harm to government services and American citizens.
In 2021, President Biden declared that “cybersecurity threats posed to the systems that control and operate the critical infrastructure on which we all depend are among the most significant and growing issues confronting our Nation. The degradation, destruction, or malfunction of systems that control this infrastructure could cause significant harm to the national and economic security of the United States.”
The administration’s policy recognizes the cybersecurity threats to industrial control systems and other related operational technology. When cyber attacks start to have physical and real-world impacts through control systems and operational technology, they harm the American people.
Maintaining and understanding risks introduced into your supply chain through industrial control systems in suppliers and service providers is crucial in achieving enhanced cybersecurity.
