Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (8e1008cff7bb82464ce9ade3ae5c353e929b7367800b404a038baa8a026c69ae) The package name resembles utilities in the Solana ecosystem (e.g., @solana/addresses and address codec helpers), which is a common target for typosquat and confusion attacks against crypto tooling. No file-level behavioral evidence was produced for this version, so malicious intent cannot be confirmed or ruled out from the available signals. Given the crypto-adjacent naming and the absence of behavioral evidence, human review is appropriate before allowing installers to consume this package. ## Source: ghsa-malware (d0da02ad73e46c13e48f34ef7449ff27d9d3beeeb28d6c2b905e30ee3fd810d1) Any computer that has this package installed or running should be considered fully compromised. 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.

Impact

Systems with solana-address-codec versions 1.0.0 or 1.0.1 installed are at risk of full compromise. Attackers may gain complete control over the system, potentially accessing all stored secrets and keys. This level of compromise can lead to unauthorized data access, credential theft, and further malicious activity. Simply removing the package may not fully eradicate the threat due to possible persistence mechanisms installed by the malicious code.

Defensive guidance

Remove the solana-address-codec package versions 1.0.0 and 1.0.1 immediately from all affected systems. Rotate all secrets and keys stored on compromised systems using a separate, trusted environment. Because full system compromise is possible, consider rebuilding or thoroughly cleaning affected systems.

Summary

The solana-address-codec package versions 1.0.0 and 1.0.1 have been identified as containing malicious code or relying on a dependency that contains malicious code. According to the source data from Amazon Inspector and GHSA malware advisories, any system with these package versions installed should be considered fully compromised. The malicious code may allow an attacker to gain full control over the affected system, necessitating immediate secret and key rotation from a clean environment.
