If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

Importing the package automatically launches a detached JavaScript loader that retrieves and executes additional code from npoint.io. The retrieved payload communicates with an attacker-controlled server and implements clipboard collection, keyboard and mouse event collection, filesystem scanning, and theft of Chrome extension storage.\n\nOn import, index.js calls initialize() which spawns a detached, stdio-suppressed `node loader.js` child process. loader.js issues an HTTPS GET to https://api.npoint.io/24c12c4b66a29747764f, base64-decodes the `code` field of the response, and executes it via `new Function(require, __dirname, __filename, module, exports, decodedCode)` — arbitrary code from a third-party mutable JSON hosting bin runs with full Node privileges on the installer's machine. loader.js additionally monkey-patches `Module.prototype.require` so any subsequent `require('child_process').spawn`/`execSync` call is rewritten to force `windowsHide:true` and route execSync through a hidden `cmd.exe /c` spawnSync, ensuring commands issued by the remotely fetched payload run invisibly on Windows. The detached-and-unref'd child, suppressed stdio, and stealth child_process wrapper are consistent with a persistent covert loader whose actual behavior is controlled by whoever owns the npoint bin.","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 id79-client (npm)","id":"MAL-2026-16173","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":"id79-client","purl":"pkg:npm/id79-client","source":"MAL-2026-16173"}],"products":null,"published":"2026-09-12","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-2026-16173/"}
