--- _-= Per source details.

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 mjs-biginteger package versions 5.0.5 and 5.0.6 distributed via npm contain embedded malicious code that compromises the host system. According to the source advisory, installation or execution of these versions results in full system compromise, potentially exposing all stored secrets and keys. The advisory warns that removal of the package does not guarantee eradication of all malicious artifacts, indicating persistence mechanisms or additional payloads may be present. No CVSS score or detailed technical exploit information is provided. No official patch or remediation guidance is available in the provided data.
Potential Impact
Systems with mjs-biginteger versions 5.0.5 or 5.0.6 installed or running are fully compromised, risking exposure of all secrets and keys stored on those systems. The compromise may allow an attacker full control over the affected computer. Removal of the package alone is insufficient to ensure system integrity due to potential persistence of malicious software.
Mitigation Recommendations
Immediate removal of the mjs-biginteger package versions 5.0.5 and 5.0.6 is recommended. All secrets and keys stored on the compromised system should be rotated immediately using a separate, secure device. Because the system may remain compromised even after package removal, a full system investigation and remediation is advised. No official patch or fix is currently documented; monitor vendor advisories for updates.
