Supply Chain Attacks Industrialized: SaaS, Open Source, and MSP Ecosystems as Primary Attack Vectors in 2026
In 2026, threat actors have industrialized supply‑chain compromise, treating SaaS platforms, open‑source repositories, and managed service provider (MSP) ecosystems as repeatable production lines. Initial access is gained via credential stuffing or phishing, followed by insertion of malicious code into npm packages, hijacked GitHub Actions workflows, trojanized SaaS plugins, and backdoored MSP RMM agents. These compromised vectors enable lateral movement through trusted update mechanisms and monetization via ransomware, data exfiltration, or cryptojacking, with attack frameworks sold as a service lowering the barrier for large‑scale campaigns.
