Malicious code in os-ulid-void (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (ae1f330082068d43b4ef645b06ce190fb0354367ab0d98edadd3f15c6c99dea1) The package ships a minified file at dist/payload.js where multiple HTTP POST call sites appear (lines 14503, 14532, 14716, 14834, 15716). The literal evidence captured is only the keyword 'POST' without surrounding context, so the destinations, request bodies, and reachability (install-time vs import-time vs explicit user-call) cannot be determined from the available signals. The package name resembles common ULID utility naming and may be a confusion candidate, but no concrete installer-harm code path (env-var scrape, credential read, hardcoded attacker endpoint, dropper, lifecycle hook tied to an exfil call) has been verified. Manual review of dist/payload.js is recommended to confirm whether the POST sites target attacker-controlled destinations or are part of legitimate API surface. ## Source: ghsa-malware (531ba01f5b5d2442cc8070ae6feec31976f9b67957fa3b0936c2cea7b6034b81) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
AI Analysis
Technical Summary
The os-ulid-void npm package version 3.0.2 includes a minified JavaScript file (dist/payload.js) containing multiple HTTP POST calls. Although the precise endpoints and payloads of these calls are not fully determined, the package is flagged as malicious by the GHSA-malware source. Systems with this package installed or running are considered fully compromised, with potential exfiltration or unauthorized control. No patch or fix is currently documented. Manual code review is recommended to understand the exact malicious behavior, but immediate remediation steps are advised due to the high risk.
Potential Impact
Any system with os-ulid-void version 3.0.2 installed or running is considered fully compromised. Attackers may have gained full control, potentially accessing secrets and keys stored on the system. This necessitates immediate rotation of all credentials from a secure, uncompromised environment. Simply removing the package does not guarantee removal of all malicious artifacts or backdoors introduced by the package.
Mitigation Recommendations
No official patch or fix is currently available. Immediate removal of the os-ulid-void package version 3.0.2 is recommended. All secrets and keys on the affected system should be rotated from a different, trusted machine. Due to the potential full system compromise, a thorough incident response and system rebuild may be necessary. Manual review of the package's dist/payload.js file is advised to understand the malicious behavior and confirm the extent of compromise.
