Description

The npm package '@business_promocode/cancel_promocode' version 99.0.3 has been identified as containing malicious code. Installation or execution of this package can lead to full compromise of the affected computer, potentially exposing all stored secrets and keys. Immediate removal of the package and rotation of all credentials from a secure machine are strongly recommended. However, removal alone may not fully eradicate the malicious presence due to possible persistence mechanisms.

Impact

Systems with the malicious package installed are considered fully compromised. Attackers may gain full control over the affected computer, including access to sensitive secrets and keys. This can lead to unauthorized data access, credential theft, and further malicious activities. Simply removing the package does not guarantee complete remediation due to potential persistence of malicious software.

Defensive guidance

Remove the '@business_promocode/cancel_promocode' package version 99.0.3 immediately from all affected systems. Rotate all secrets and keys stored on the compromised machines from a separate, secure computer. Because full system compromise is possible, consider conducting a thorough incident response and system integrity verification to ensure all malicious artifacts are eradicated.
