Supply Chain Attacks in 2026: Lessons from ForceMemo & Cisco SD-WAN Zero-Day for NIS2 & DORA Compliance

The Escalating Threat of Supply Chain Attacks in 2026

As digital ecosystems become more interconnected, supply chain attacks have emerged as one of the most potent and disruptive cybersecurity threats facing organizations in 2026. Unlike traditional attacks that target a single entity, supply chain attacks exploit vulnerabilities in third-party software, services, or components to compromise a wide network of downstream victims. This approach allows threat actors to achieve maximum impact with minimal effort, often bypassing conventional security defenses. Two recent high-profile incidents—the ForceMemo campaign targeting Python repositories and the long-term exploitation of a Cisco SD-WAN zero-day vulnerability—illustrate the sophistication and persistence of modern adversaries. These attacks not only cause immediate operational and financial damage but also expose organizations to significant regulatory scrutiny under emerging frameworks like the NIS2 Directive and the Digital Operational Resilience Act (DORA). Understanding these threats is the first step toward building a resilient security posture that aligns with compliance mandates and protects critical assets.

Case Study 1: The ForceMemo Campaign and Python Repository Compromise

The ForceMemo campaign represents a sophisticated supply chain attack that targeted Python repositories on GitHub through compromised developer credentials. According to analysis, threat actors stole credentials via the VS Code GlassWorm malware campaign, which initially emerged in October 2025 targeting Visual Studio developers with malicious extensions. Using these stolen credentials, attackers injected obfuscated malicious code into hundreds of Python projects, including Django applications, machine learning research code, and PyPI packages. The attack vector involved rebasing legitimate commits and force-pushing them to repositories, a technique designed to hide traces and evade detection by making malicious changes appear as part of normal development activity.

The malware employed advanced evasion tactics, such as using the Solana blockchain to fetch encrypted JavaScript payloads and command-and-control instructions. Evidence suggests origins in Eastern European cybercrime groups, highlighting the global nature of these threats. The ForceMemo campaign is part of the broader GlassWorm malware ecosystem, which has expanded to target NPM and GitHub, compromising over 150 repositories in recent attacks. A key finding is the use of transitive delivery methods in VS Code extensions, where benign extensions are turned into installers for malicious ones, demonstrating how attackers continuously innovate to exploit trust in software supply chains.

Case Study 2: Long-Term Exploitation of Cisco SD-WAN Zero-Day

In a separate but equally alarming incident, a sophisticated threat actor exploited a maximum-severity vulnerability (CVE-2026-20127) in Cisco SD-WAN for approximately three years, leaving minimal evidence behind. This zero-day vulnerability represented a critical security risk, as it remained undetected and actively exploited over an extended period. The exploitation by an unknown advanced actor underscores significant gaps in vulnerability management, threat detection, and incident response capabilities within many organizations.

Similar to the ForceMemo campaign, this attack involved advanced evasion tactics that allowed it to persist undetected. The long-term nature of the exploitation raises concerns about supply chain security, particularly for networking products that form the backbone of enterprise infrastructure. It highlights how vulnerabilities in widely used vendor software can become gateways for sustained attacks, compromising not only the direct target but also any downstream systems reliant on that software. This incident serves as a stark reminder that traditional patch management and monitoring approaches may be insufficient against determined adversaries who specialize in stealth and persistence.

Common Tactics and Gaps in Cybersecurity Frameworks

Both the ForceMemo and Cisco SD-WAN attacks share several common tactics that expose gaps in existing cybersecurity frameworks:

• Evasion and Persistence: Attackers used techniques like rebasing commits and minimal evidence leave to avoid detection, challenging conventional security tools.
• Exploitation of Trust: By compromising legitimate developer accounts or vendor software, attackers leveraged trust in supply chains to spread malware.
• Extended Timeframes: The Cisco SD-WAN exploitation lasted three years, while ForceMemo involved ongoing campaigns, highlighting failures in continuous monitoring.

These incidents reveal limitations in widely adopted frameworks like the NIST Cybersecurity Framework (CSF) 2.0, which, while valuable, may not fully address supply chain-specific risks without tailored implementation. For example, the Govern function in NIST CSF 2.0 emphasizes organizational oversight, but many organizations lack dedicated processes for third-party risk assessment in development pipelines. Similarly, the Detect function may fall short against advanced obfuscation techniques used in these attacks. Compliance standards like ISO/IEC 27001:2022 provide a structured approach to information security management, but certification does not guarantee immunity to sophisticated supply chain threats, as seen in these cases.

Compliance Risks Under NIS2 and DORA Regulations

The ForceMemo and Cisco SD-WAN incidents pose direct compliance risks under two key EU regulations: the NIS2 Directive and the Digital Operational Resilience Act (DORA).

NIS2 Directive Compliance Gaps

NIS2 Directive (Directive (EU) 2022/2555) aims to enhance cybersecurity across essential and important entities in sectors like energy, transport, health, and digital infrastructure. Member states had a transposition deadline of 17 October 2024. Key requirements include risk management measures, incident reporting within 24 hours for early warning and 72 hours for detailed notification, supply chain security, and management accountability. Penalties can reach up to EUR 10 million or 2% of global turnover for essential entities.

The attacks discussed expose potential non-compliance areas:

• Supply Chain Security: NIS2 mandates securing supply chains, but many organizations lack robust vendor risk assessments for software components, as seen in the ForceMemo campaign.
• Incident Reporting: The prolonged exploitation of Cisco SD-WAN suggests failures in timely detection and reporting, which could violate NIS2's strict timelines.
• Risk Management: Inadequate vulnerability management, evidenced by the three-year zero-day exploitation, may fall short of NIS2's required risk mitigation measures.

DORA Compliance Implications

DORA (Regulation (EU) 2022/2554) applies from 17 January 2025 to financial entities like banks, insurers, and payment institutions. It focuses on digital operational resilience, requiring an ICT risk management framework, incident reporting, resilience testing (including threat-led penetration testing), and third-party ICT risk management.

These attacks highlight DORA compliance challenges:

• Third-Party ICT Risk Management: Financial entities relying on Cisco SD-WAN or Python libraries could face disruptions, emphasizing the need for rigorous vendor due diligence as required by DORA.
• Incident Response: DORA mandates robust response plans, but stealthy attacks like these may evade initial detection, complicating compliance.
• Resilience Testing: The sophistication of these attacks underscores the importance of advanced testing, such as threat-led penetration testing, to identify hidden vulnerabilities.

Organizations can use platforms like AIGovHub to navigate these complex regulations, with tools for compliance intelligence and vendor comparisons to ensure alignment with NIS2 and DORA requirements.

Actionable Mitigation Strategies for Supply Chain Security

To defend against supply chain attacks and meet compliance obligations, organizations should implement a multi-layered strategy:

1. Implement Secure Development Practices: Adopt principles like code signing, dependency scanning, and least-privilege access for developers. For example, requiring multi-factor authentication (MFA) could have mitigated credential theft in the ForceMemo campaign.
2. Enhance Continuous Monitoring: Deploy security tools that monitor for anomalous activities, such as unexpected force-pushes in Git repositories or unusual network traffic from devices like SD-WAN appliances. Continuous monitoring aligns with NIS2 and DORA requirements for proactive threat detection.
3. Develop Robust Incident Response Plans: Create and regularly test plans that include supply chain-specific scenarios. Ensure procedures meet NIS2's 24/72-hour reporting deadlines and DORA's resilience standards.
4. Conduct Regular Vendor Risk Assessments: Evaluate third-party suppliers for security postures, using frameworks like NIST CSF 2.0 or ISO/IEC 27001:2022 as benchmarks. This is critical for compliance with NIS2's supply chain security and DORA's third-party risk management clauses.
5. Prioritize Patch Management: Establish automated processes for vulnerability scanning and patching, reducing windows of exposure like the three-year gap in the Cisco SD-WAN case.

Leveraging Security Tools for Enhanced Protection

Modern security tools can significantly bolster defenses against supply chain attacks. Vendors like CrowdStrike offer endpoint detection and response (EDR) solutions that use AI-driven threat hunting to identify malicious activities, such as the obfuscated code injections in ForceMemo. Snyk provides software composition analysis (SCA) tools that scan dependencies for vulnerabilities, helping prevent compromises in Python packages or other open-source components. These tools integrate with development pipelines to enforce security early in the software lifecycle, addressing gaps highlighted by both case studies.
