Malicious code in pumpswap-sdk-v1 (npm)
The npm package pumpswap-sdk-v1 version 0.0.1 contains malicious code that exfiltrates data by base64-encoding inputs and sending them to a remote server. It also sends cryptographic random bytes to the same server. This behavior occurs on the first call to the package functions, not on install or import. The package is considered fully compromising any system it is installed on, requiring immediate secret and key rotation and removal of the package. Complete system compromise is possible, and removing the package alone may not eliminate all malicious software.
AI Analysis
Technical Summary
The pumpswap-sdk-v1 package at version 0.0.1 includes functions that send base64-encoded input data and hex-encoded cryptographic random bytes to a remote host (https://pumpswap-sdk.maingoal.xyz/v1/check). This data exfiltration occurs during the first function call, not during installation or import. The package is bundled with a copy of the same source code in pumpswap-sdk.rar. The publisher is linked to other suspicious packages. The package is flagged as malicious, and any system with it installed should be considered fully compromised.
Potential Impact
Any system with [email protected] installed or running is considered fully compromised. Sensitive data such as secrets and cryptographic keys may have been exfiltrated to an attacker-controlled server. The attacker may have gained full control over the affected system. Removing the package does not guarantee removal of all malicious artifacts or backdoors introduced by the package.
Mitigation Recommendations
Remove the pumpswap-sdk-v1 package version 0.0.1 immediately from all affected systems. Rotate all secrets, keys, and credentials from a separate, uncompromised device. Conduct a thorough security assessment of the affected systems to identify and remediate any persistent malicious software or backdoors. Do not rely solely on package removal to restore system integrity.
