AI Analysis
Technical Summary
The npm package dolyame-boxy-independent-bnpl-cards version 35.7.6 includes malicious functionality triggered on import. Its index.js requires setup.js, which downloads a binary payload from multiple obfuscated Cloudflare Workers domains, with a DNS TXT covert-channel fallback through unrelated domains. The payload is saved to temporary directories with disguised names (dotnet_diag_<uid>.exe on Windows, .cache_<uid> on Unix), permissions set to executable, and launched detached via shell commands. There is no integrity verification of the downloaded payload. Hostnames are dynamically constructed from array fragments at runtime. The package’s stated purpose (BNPL cards) is unrelated to this behavior. A lockfile and environment variables related to telemetry are used as a cover story to mask malicious activity.
Potential Impact
This malicious package can execute arbitrary code on the host system by downloading and running an unverified binary payload. This can lead to full system compromise, unauthorized access, data theft, or further malware installation. The obfuscation and covert-channel techniques increase the difficulty of detection and analysis.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should immediately remove version 35.7.6 of dolyame-boxy-independent-bnpl-cards from their environments. Avoid installing or using this package. Monitor for any unexpected processes or files matching the described patterns. Check vendor or repository advisories for updates or removals of this malicious package.
