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.

The attacker (npm user **t-in-one**, email `nath.dr4k3@gmail.com`) published packages at inflated versions that resolve ahead of private registry versions via npm's default version resolution. The campaign shares the same C2 endpoint (`https://oob.moika.tech/report`), second-stage payload host (`https://oob.moika.tech/payload`), and hardcoded secret (`l95HdDaz3kQx1Zsg3WxH6HvKANf51RY1`) as Wave 1 (npm users **mr.4nd3r50n** and **pik-libs**, published 2026-05-27).\n\nOn installation, the `postinstall` hook executes a three-layer obfuscated `scripts/postinstall.js` (obfuscator.io + custom base64 alphabet + integer-shuffle string table). The script checks a run-once guard at `~/.cache/._t-in-one_init/` and respects a `T_IN_ONE_NO_TELEMETRY` kill switch before proceeding. It then downloads an OS-specific second-stage JavaScript payload from `https://oob.moika.tech/payload/{mac|win|linux}.js`, writes it to a temporary file, and spawns it as a detached Node.js process that continues running after npm exits. The payload exfiltrates the full `process.env` (environment variables including secrets, tokens, and credentials), along with hostname, username, platform, architecture, and working directory, to `https://oob.moika.tech/report`.\n\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.","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 @t-in-one/get_application_hid (npm)","id":"MAL-2026-5039","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":["0"],"last_affected":[],"package":"@t-in-one/get_application_hid","purl":"pkg:npm/%40t-in-one%2Fget_application_hid","source":"MAL-2026-5039"}],"products":null,"published":"2026-05-29","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-2026-5039/"}
