AI Analysis
Technical Summary
This malicious npm package unconditionally loads a polyfill script that downloads a platform-specific binary payload from dynamically reconstructed Cloudflare Workers hostnames. If this primary channel fails, it uses DNS TXT queries to retrieve base64-encoded payload chunks from specific domains. The payload is written to temporary directories with disguised filenames and executed detached from the main process without hash or signature verification. Execution is controlled by the presence of an 'analytics_state' filesystem stamp and uses misleading naming conventions to avoid detection. The package name impersonates a legitimate payment integration, facilitating its distribution and use.
Potential Impact
The package enables remote code execution on the host system by downloading and executing arbitrary binaries without verification. This can lead to full system compromise, unauthorized access, or further malware deployment. The malicious behavior is triggered simply by requiring the package, making it a severe supply chain threat to any project that installs this version.
Mitigation Recommendations
No official patch or remediation is currently available. Users should immediately remove and avoid using version 35.4.8 of the 'dolyame-boxy-atom-desktop-bnpl-dangerously-html' package. Audit dependencies for this package and replace it with trusted alternatives. Monitor for any suspicious activity related to this package. Patch status is not yet confirmed — check the vendor advisory or trusted security sources for updates.
