In late June 2017, the cybersecurity world was shaken by a significant event when A.P. Møller – Maersk, one of the largest maritime companies, fell victim to a devastating software infection that impacted nearly a fifth of the global shipping capacity. Initially believed to be a targeted attack on Maersk, it was later revealed that the incident stemmed from a regional conflict between Ukraine and Russia, resulting in the spread of the NotPetya malware through a Ukrainian software company with worldwide clientele.

The aftermath of this cyberattack was staggering, leading to an estimated $10 billion in damages, making it the most costly cyber event in history. NotPetya went on to become one of the most infamous cyberattacks ever recorded, highlighting the vulnerabilities in software supply chains worldwide. This incident marked a shift in the cybersecurity landscape, emphasizing the importance of securing commercial software updates and mitigating supply chain risks.

In the years following the NotPetya attack, there has been a surge in similar incidents targeting software supply chains, with notable cases involving SolarWinds and 3CX. The rise in breaches originating from third-party software development organizations underscored the need for enhanced security measures to protect against such threats. This trend was further illuminated in Verizon’s “2024 Data Breach Investigations Report,” which revealed a significant increase in breaches linked to third-party software suppliers.

To address these growing concerns, the US Cybersecurity and Infrastructure Security Agency (CISA) introduced the Secure by Design initiative in 2023, urging software producers to prioritize security in product design and implementation. This initiative aimed to improve transparency, track vulnerabilities, and promote secure authentication practices within the supply chain. Building upon this framework, CISA unveiled the Secure by Demand guidelines in August 2024, empowering enterprise buyers to demand safer software products from vendors.

While Secure by Demand represents a crucial step towards enhancing software assurance, there are critical gaps that must be addressed to truly safeguard organizations. The reliance on questionnaires and software bills of materials (SBOMs) for risk assessment may fall short in providing comprehensive security assurance, as evidenced by the NotPetya attack. Enterprises must go beyond these standard practices and adopt independent validation measures to verify the integrity and safety of commercial software.

Sophisticated cyber threats have evolved to target commercial software directly, bypassing traditional security checks on open source components. By implementing robust software supply chain security solutions, organizations can independently assess software for malicious code, vulnerabilities, and suspicious behaviors. This proactive approach allows enterprises to verify the reliability of their mission-critical software and defend against potential supply chain attacks effectively.

In conclusion, the evolving threat landscape necessitates a paradigm shift in how organizations approach software assurance and supply chain security. By moving towards a trust-but-verify model, enterprises can mitigate risks, strengthen their cyber defenses, and safeguard critical assets from emerging threats in the digital age.
