If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3.

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\nThe OpenSSF Package Analysis project identified '@asavie/i18n' @ 99.0.1 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n\n- The package executes one or more commands associated with malicious behavior.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in @asavie/i18n (npm)","id":"MAL-2026-4265","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"@asavie/i18n","purl":"pkg:npm/%40asavie%2Fi18n","source":"MAL-2026-4265"}],"products":null,"published":"2026-05-23","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-4265/"}
