Understanding the increase in Supply Chain Security Attacks

The European Union Agency for Cybersecurity mapping on emerging supply chain attacks finds 66% of attacks focus on the supplier’s code.
Supply chain attacks have been a concern for cybersecurity experts for many years because the chain reaction triggered by one attack on a single supplier can compromise a network of providers. Malware is the attack technique that attackers resort to in 62% of attacks.
According to the new ENISA report - Threat Landscape for Supply Chain Attacks, which analysed 24 recent attacks, strong security protection is no longer enough for organisations when attackers have already shifted their attention to suppliers.
This is evidenced by the increasing impact of these attacks such as downtime of systems, monetary loss and reputational damage.
Supply chain attacks are now expected to multiply by 4 in 2021 compared to last year. Such new trend stresses the need for policymakers and the cybersecurity community to act now. This is why novel protective measures to prevent and respond to potential supply chain attacks in the future while mitigating their impact need to be introduced urgently.
Why is a good level of cybersecurity not good enough?
Composed of an attack on one or more suppliers with a later attack on the final target, namely the customer, supply chain attacks may take months to succeed. In many instances, such an attack may even go undetected for a long time. Similarly to Advanced Persistence Threat (APT) attacks, supply chain attacks are usually targeted, quite complex and costly with attackers probably planning them well in advance. All such aspects reveal the degree of sophistication of the adversaries and the persistence in seeking to succeed.
The report reveals that an organisation could be vulnerable to a supply chain attack even when its own defences are quite good. The attackers explore new potential highways to infiltrate organisations by targeting their suppliers. Moreover, with the almost limitless potential of the impact of supply chain attacks on numerous customers, these types of attacks are becoming increasingly common.
In order to compromise the targeted customers, attackers focused on the suppliers’ code in about 66% of the reported incidents. This shows that organisations should focus their efforts on validating third-party code and software before using them to ensure these were not tampered with or manipulated.
For about 58% of the supply chain incidents analysed, the customer assets targeted were predominantly customer data, including Personally Identifiable Information (PII) data and intellectual property.
For 66% of the supply chain attacks analysed, suppliers did not know, or failed to report on how they were compromised. However, less than 9% of the customers compromised through supply chain attacks did not know how the attacks occurred. This highlights the gap in terms of maturity in cybersecurity incident reporting between suppliers and end-users.

CISA Releases ICT Supply Chain Risk Management Task Force Year 2 Report

The Cybersecurity and Infrastructure Security Agency (CISA) and government and industry members of the Information and Communications Technology (ICT) Supply Chain Risk Management (SCRM) Task Force released an annual report on its progress to advance meaningful partnerships and analysis around supply chain security and resilience.
The ICT SCRM Task Force Year 2 Report builds upon previous work completed in year one of the ICT SCRM Task Force. It showcases the collective ongoing efforts of four working within the Task Force to address challenges to information sharing, threat analysis, qualified bidder and qualified manufacturer lists, and vendor assurance. It also reflects a new working group, Working Group 5, which recently released an analysis report on the impacts of the COVID-19 pandemic on ICT supply chains.
Developed through the expertise and contributions of government and industry, the ICT SCRM Task Force Year 2 Report addresses the lifecycle of supply chain risk management, including how stakeholders identify and understand risk, communicate about and work together to address risk, grow their structural operations for addressing risks, and improve their understanding and self-assessment of their risk posture.
“Government can’t act in a silo,” said Bob Kolasky, CISA Assistant Director and ICT SCRM Task Force Co-Chair. “We must work in partnership with public and private industry. The Task Force has and will continue to serve as a model of excellence in helping to improve the Nation’s collective ability to assess and mitigate threats to the ICT supply chain.”
“As we were reminded this week, supply chain security is a matter of urgency and consequence, and the best way to increase our defenses is through substantial coordination and cooperation between government and industry,” said Robert Mayer, Senior Vice President of Cybersecurity and Innovation at USTelecom and ICT SCRM Task Force Co-Chair. “That is the mission of our task force. Through this partnership with DHS and more than a dozen agencies, the Information Technology and Communications sectors has tackled tough issues like information sharing, threat assessment, qualified bidders and manufacturer lists, and security issues presented by the pandemic. This is a partnership that will expand in 2021 and further strengthen the security and resiliency of our supply chain.”
“For the past two years, the Information Technology and Communications sectors have worked hand-in-glove with CISA and other federal government partners to establish the Task Force as the preeminent public-private partnership tackling the critical issue of global ICT supply chain security,” said John Miller, Senior Vice President of Policy and Senior Counsel at Information Technology Industry Council (ITI) and ICT SCRM Task Force Co-Chair. “The Year 2 Report represents a significant milestone, delivering actionable recommendations to help public and private sector organizations better assess and manage supply chain risks, including by creating tools to address supply chain threat information sharing, threat analysis, and vendor assurance and trust. The Task Force looks forward to working with our federal partners in 2021 and beyond to operationalize the policy recommendations in this report to better manage today’s all-too-real supply chain threats and to develop future work products that will address other dimensions of this important national security issue.”
The Task Force plans to release working group reports described in the Year 2 Report in the coming weeks. Members will continue to explore means for building partnerships with international partners, new sectors, and stakeholders who can help grow the applicability and utilization of Task Force products.
