CISA issued an alert regarding a software supply chain compromise affecting the Axios npm package. Malicious versions of Axios, specifically [email protected] and [email protected], injected a dependency called [email protected]. This malicious dependency downloads multi-stage payloads, including a remote access trojan, from actor-controlled infrastructure. Organizations must monitor code repositories, CI/CD pipelines, and developer machines for the compromised Axios versions. They should also check artifact repositories for cached malicious dependencies and pin package versions to known safe releases. If compromised dependencies are found, environments need to be reverted to a safe state and credentials potentially exposed should be rotated. Monitoring for unexpected child processes and anomalous network behavior during npm operations is crucial. Blocking outbound connections to Sfrclak[.]com domains is also recommended. CISA further advises implementing phishing-resistant MFA for developer accounts and configuring npm to ignore scripts and enforce minimum release ages for packages. Establishing normal execution baselines and alerting on anomalous dependency behavior will help detect and prevent future compromises.
