Description

The npm package @ethersphere/bee-js version 13.3.0 contains malicious code. Any system with this package installed or running is considered fully compromised, with potential unauthorized access to all secrets and keys stored on the machine. Immediate removal of the package and rotation of all secrets from a different, uncompromised device is strongly advised. However, removal of the package alone may not eliminate all malicious software introduced by the compromise.

Impact

Systems with the malicious @ethersphere/bee-js package installed are fully compromised, risking exposure and theft of all stored secrets and keys. This can lead to unauthorized access, data breaches, and further system control by attackers. The compromise is severe enough that secrets must be rotated from a separate, secure environment to prevent continued exploitation.

Defensive guidance

Remove the @ethersphere/bee-js package version 13.3.0 immediately. Rotate all secrets and keys from a different, uncompromised device. Because the system may be fully compromised, additional forensic investigation and remediation may be necessary beyond package removal to ensure all malicious components are eradicated.

Summary

The @ethersphere/bee-js package at version 13.3.0 has been identified as containing malicious code. Installation or execution of this package results in a full compromise of the affected system, potentially allowing an attacker to gain control and access sensitive information such as secrets and keys. The advisory emphasizes that simply uninstalling the package may not fully remediate the infection, as the attacker may have installed additional persistent malicious components.
