AI Analysis
Technical Summary
The @jaime9008/math-service npm package versions 1.0.0 through 1.0.2 is classified as malware due to the presence of obfuscated code and use of eval() to execute malicious payloads. The file lib/lib.js contains the same obfuscated malware dropper as the known malicious react-refresh-update package authored by the same individual. This malware can fully compromise any system where the package is installed, potentially allowing unauthorized control and exfiltration of sensitive information.
Potential Impact
Systems with this package installed are considered fully compromised. Attackers may have gained full control, risking exposure of all stored secrets and keys. Simply removing the package does not guarantee removal of all malicious artifacts or backdoors introduced by the malware.
Mitigation Recommendations
Remove the @jaime9008/math-service package immediately from all affected systems. Rotate all secrets, credentials, and keys that were stored or accessible on compromised machines, using a separate, secure environment. Conduct a thorough investigation and system cleanup to identify and remove any persistent malicious components beyond the package itself.
