The collected JSON is POSTed over HTTPS to a hardcoded Interactsh out-of-band collector (`d8acb4hon5btn99s9lsgakhs31dmwk9cr.oast.pro`) plus a DNS callback to the same host. The package name and the inclusion of `WALMART`/`WMT` in the env-var harvest list indicate this is dependency-confusion bait targeting Walmart\u0027s internal `@xarc/*` scope; package.json self-describes it as \u0027authorized dependency confusion testing\u0027 but ships with no authorization gate, so any installer that resolves this name has its CI/CD tokens, cloud credentials, and source metadata shipped to the attacker-controlled OOB host.\n\n## Source: ghsa-malware (401efd45edfe86b2e2f3c6a0fb591b94bbae8bb50162ebc0c8bd5bfdfaa9e6f6)\nAny 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.\n\n## Source: ossf-package-analysis (b9a1bb4adee0a346eeb247af4ef6569464a634fe87576a149a44f5ececd15d90)\nThe OpenSSF Package Analysis project identified \u0027xarc-webpack-cli\u0027 @ 1.0.0 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n",
