Summary
Malicious code in voyager-web (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (a7f4f15201378ec6cee4268469e85e17e50f3f5299d94a250031d6c2693177b8)

package.json declares both preinstall and postinstall lifecycle hooks that execute callback.js on npm install. callback.js collects installer-side identifiers (os.hostname(), username, uid/gid, homedir, platform, cwd, local IP, external IP via https://api.ipify.org, Node version, package name) and CI environment indicators (presence of GITHUBTOKEN/AWSACCESSKEYID/NPMTOKEN, GITHUBREPOSITORY, GITHUBACTOR, JENKINSURL, etc.) and POSTs the JSON payload to a hardcoded Discord webhook at discord.com/api/webhooks/1514602063399747595/<redacted>. A DNS-based exfiltration fallback is also present. The package name typosquats Reddit's open-source voyager-web and the version 999.0.0 is the canonical dependency-confusion version-bump used to override an internal/private package of the same name. Self-described as a security research PoC, but the binary effect on any non-consenting installer is automatic exfiltration of host and CI credentials/metadata to an attacker-controlled channel.

Source: ghsa-malware (3704dd10a97df91da057174a7a79eef2b45b61c8c2825300633ee129f296bc25)

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.
