Software supply chain attacks have emerged as a significant and growing cybersecurity threat, targeting trusted vendors and injecting malicious code into software applications. The risk of such attacks has become more prevalent in a world where IT, DevOps, and even security teams authorize third-party tools and services to streamline development. How can organizations protect themselves from such threats?
The growing trend of bottom-up software adoption and freemium cloud services results in connections done by developers without proper security governance, creating shadow connections between sensitive engineering systems and external applications.
According to Statista, showcasing the escalating threat landscape, the global count of software packages impacted by supply chain attacks increased significantly from 702 in 2019 to 185,572 in 2022. This surge in supply chain attacks reflects the vulnerabilities introduced by ungoverned connections made by developers.
Looking ahead, Gartner predicts that by 2025, 45 percent of global organizations will have encountered software supply chain attacks, marking a threefold rise from the figures in 2021.
Software supply chain attacks aim to exploit vulnerabilities in the supply chain to gain unauthorized access to sensitive systems and data. This can occur through compromised software vendors with access to critical infrastructure or cloud services.
Attackers target these vendors to gain entry into the larger supply chain and potentially compromise multiple organizations. Using third-party APIs, open-source code, and proprietary software components increases the attack surface, making it challenging to detect and mitigate these threats effectively.
To defend against software supply chain attacks, organizations need to be vigilant and proactive in identifying and addressing potential vulnerabilities.
As organizations increasingly rely on third-party vendors and off-the-shelf software components, the risk of supply chain attacks has become more prevalent and complex. Businesses must understand the nature of these attacks, their impact, and strategies to detect, mitigate, and prevent them.
Integrating third-party tools involves API keys, service accounts, webhooks, OAuth tokens, and SSH keys. Users often grant high-level permissions, creating shadow connections between sensitive systems and external applications. These connections remain active even after the user has completed their tasks.

Software supply chain attacks employ various strategies to infiltrate and distribute malicious payloads within the supply chain. Attackers may:
Attackers may exploit the vulnerabilities created by ungoverned connections, further emphasizing the importance of addressing these issues. Organizations can enhance their ability to detect and mitigate the risk of supply chain attacks by gaining insights into attackers' methods.
Mitigation Measures:
Understanding and implementing these strategies are crucial steps in identifying and preventing infiltrations.
Companies should be cautious when utilizing third-party solutions and open-source components, as they can be vulnerable. These attacks have gained prominence due to the continuously evolving nature of cyber threats.
The SolarWinds attack, one of the most notable examples, injected malicious code into the software build cycle, compromising approximately 18,000 downstream customers, including major firms and government agencies. This attack demonstrated the far-reaching consequences of a supply chain breach and the potential for widespread damage.
Recent incidents, such as those involving Okta, GitHub, and Microsoft, underscore the risks associated with insecure non-human access. The compromise of OAuth tokens, API keys, and other programmable access keys in various attacks has exposed sensitive information and triggered data breaches.
Other incidents, such as those targeting Target, Home Depot, and NotPetya, have further underscored the severity of software supply chain attacks. These attacks have resulted in significant financial losses, reputational damage, and compromised customer data.
The incidents highlight the urgent need for improved governance and security measures to prevent unauthorized connections and potential breaches.
The escalating problem arises from widespread access delegation to third-party cloud services and AI tools, creating an ungoverned attack surface. Despite this, security solutions often fall short, focusing on securing user credentials rather than monitoring app-to-app connections. The increasing frequency and intensity of OAuth attacks, fueled by the diverse business, engineering, and low-code environments, highlight the urgent need for a comprehensive supply chain security approach.
Organizations should implement strategies to identify potential signs of an attack, including monitoring for suspicious activities, analyzing network traffic, and employing threat intelligence tools.
Continuous monitoring of the software supply chain is essential to detect and respond to potential threats. This includes monitoring vendor activities, scanning vulnerabilities, and implementing secure development practices. Regular risk assessments and security audits can help identify vulnerabilities and mitigate potential risks from the supply chain.
One of the common challenges in application security is the presence of vulnerabilities in third-party libraries. Many software developers rely on third-party libraries to speed up the development process. However, these libraries may contain security flaws that attackers can exploit.
Injection attacks, cross-site scripting, insecure authentication and authorization, insufficient logging and monitoring, mobile application security, and cloud security are common issues that must be addressed in secure software development.
Addressing vulnerabilities in third-party libraries becomes even more critical, as these libraries may serve as entry points for attackers exploiting ungoverned connections.
Implementing secure software development practices is crucial in preventing software supply chain attacks. This includes conducting thorough code reviews, using secure coding standards, and regularly updating software components. Collaboration with vendors and sharing best practices can also strengthen the overall security posture of the supply chain.
Organizations can adopt Static Application Security Testing (SAST) tools to uphold best practices in secure software engineering. These tools can analyze source code and identify potential security issues early in development.
The landscape of software supply chain attacks continues to evolve as attackers find new ways to exploit vulnerabilities. Organizations must actively collaborate with cybersecurity professionals, share threat intelligence, and continuously update their defense strategies to stay ahead of these threats.
Collaborative efforts between organizations, industry groups, and government agencies significantly counter software supply chain attacks. Information-sharing platforms and coordinated response plans can help mitigate the impact of these attacks and enhance the supply chain's overall security.
The future of software supply chain security will likely involve an increased focus on proactive measures and advanced technologies. Artificial intelligence (AI) and machine learning (ML) are expected to play a significant role in assisting developers in identifying and addressing vulnerabilities in the supply chain. These technologies can help automate the detection of suspicious activities, analyze large amounts of data for patterns, and enhance overall security posture.
Software supply chain security requires ongoing innovation, collaboration, and a proactive approach to cybersecurity. In essence, the future of software supply chain security demands innovations that specifically address the risks associated with third-party non-human access.
