The package name and inflated 99.0.0 version match the classic dependency-confusion shape targeting an internal 'wos-library-ui' package (self-described as an Inditex WOS PoC): any resolver that prefers the public npm registry will pull this artifact instead of the internal one and execute the beacon, disclosing internal host identifiers and build-path details to a third-party out-of-band collector. Self-labeling as a bug-bounty PoC does not alter the installer-side effect: unconsented install-time exfiltration of installer identity from a namesquatted package on the public registry.\n\n## Source: ghsa-malware (90cbc5eda3f6536c2913b38d5ac807012bee44ce13b89750ce5d3b716fedb071)\nAny computer that has this package installed or running should be considered fully compromised.
