MAL-2026-6950

Summary: Malicious code in whs4_nmp (npm)

Details: Source: amazon-inspector (53a1fc3c42fcd64070dd50db1ed23a9f238bd10fea9bba087cb605f7419af28c) The package's `postinstall` script runs `node index.js` on install, which invokes `reportLoadedFrom` to POST installer-side data to a hardcoded Discord webhook (`discord.com/api/webhooks/1523336123319849031/...`). The transmitted payload includes the absolute filesystem path of the install location (which leaks the user's home directory / username), the Node.js version, and `process.platform`/`process.arch`. There is no disclosure, opt-in, or configuration surface — the destination is a fixed author-controlled channel. Package naming (`whs4_nmp`, internal default `whs4_typo`) and README framing (`typo 발생시 안내합니다`) indicate a dependency-confusion / typosquat probe designed to notify the author whenever a mistyped install lands on a real machine, harvesting host identifiers without consent. Source: ghsa-malware (05f2dab2e1b7ba48a8ac7e59bbaa32e72fe485b6ff9d28041becdde764394a06) 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.
