Do not edit below this line.=-_\n\n## Source: amazon-inspector (d803002ee95ea92bdcb3a918e1be10930816db383ce2a58a6947afea84e04040)\n@asavie/i18n@99.0.0 is a dependency-confusion package targeting an unclaimed npm scope. Its package.json declares a `preinstall` hook that runs `node callback.js`, which on `npm install` reads `os.hostname()` and the output of `whoami` (callback.js L23, L28) and transmits them to the attacker-controlled out-of-band collector `d88r3mao12pqka8tg04gn4ychek66c3wj.oast.site` (an Interactsh subdomain) via both a DNS A-record lookup and an `https.get()` request with the data base64url-encoded into the subdomain (callback.js L21, L37, L46). Version `99.0.0` and the squat on the `@asavie` scope are the canonical dependency-confusion shape — any build that mistakenly resolves this scope from public npm leaks identifying host data to the publisher. The tarball additionally ships an unrelated ~123 MB `google-chrome-stable_current_amd64.deb` that is not referenced by any code path; it is not executed but represents either staging or registry abuse. Author claims of 'authorized research' are unverifiable by installers and do not change the installer-side outcome: unsolicited exfiltration of host identifiers on `npm install`.\n\n## Source: ghsa-malware (552621dd1e0c7a90323428af26489ae7994047e10e73d1deb9f1a502521cd94b)\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 (c72462533b89e20b39c2336d38a51d34b95330c056845b95a3b390740cadc803)\nThe OpenSSF Package Analysis project identified '@asavie/i18n' @
