    Summary: Malicious code in b20miner (npm)

    Details: Source: amazon-inspector (4987b21d454aad64b26fee42ee36d0d0e2a8b733dc23afbd0c7fe9bb3cd9e631) No install-time execution, credential access, network exfiltration, dropper behavior, or backdoor mechanism was observed in this package version. No lifecycle scripts fetching remote content, no reads of installer-side secret paths (~/.aws, ~/.ssh, ~/.npmrc, browser stores), and no hardcoded attacker-controlled network destinations were identified. Source: ghsa-malware (6d1526b3a34c5de37870045aff69b54eb4d28fd5d1dbfe04fe23c5e1d654bdc3) 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.
