Summary
Malicious code in @pluxee-connect/account-db-api-client (npm)
Details

Source: amazon-inspector (49a36af66b1c55fbf7a78529c1fe2d15b819cef018300a03cdc8e0a1b59f36c9)

Version 99.0.0 of this package targets an internal-looking npm scope and ships a postinstall.js that, on every npm install, reads os.hostname(), os.userInfo().username, process.version, and the package name and transmits them to the third-party OAST domain d84t2rmqt3fpphmbii3gf9sdi63c3gkp7.oast.online over both HTTP GET (port 80) and DNS lookup. The package's main entry (index.js) is a placeholder stub containing only a ConsentsStatus enum with a comment self-describing it as a PoC stub mirroring the real package's API. The combination of an inflated 99.0.0 version, a hollow API surface, and an unconditional install-time beacon to an interactsh out-of-band exfiltration host on a scope that resembles an internal Pluxee namespace is a textbook dependency-confusion attack: any build system misresolving the internal name to this public package leaks host identity to the attacker's OAST listener.
