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 script collects host identity (`os.hostname()`, `whoami /all` / `id`, `ipconfig` / `ip a`), the parent project's `package.json`, git remotes, CI configuration files (`.gitlab-ci.yml`, `.github/workflows/*`, `Jenkinsfile`, `azure-pipelines.yml`), and a curated dump of environment variables matching TOKEN/AWS/AZURE/NPM/GITHUB/GITLAB/CI patterns. The collected data is HTTPS POSTed to a hardcoded interactsh OAST domain (`d8a5d9pon5bugoc35cngp9hcregcqyezu.oast.me`) with the package name as the path, plus a DNS beacon to the same host. The package name `platform-tempo` combined with version `99.0.1` is the canonical dependency-confusion shape — designed to be auto-resolved by an internal package resolver in preference to a private package of the same name. Self-described `bug bounty` framing in the package description does not change the install-time impact on any third party whose resolver picks up this public name: their CI tokens, cloud credentials, and source-tree metadata are shipped to the attacker-controlled OAST endpoint.","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 platform-tempo (npm)","id":"MAL-2026-4641","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":"platform-tempo","purl":"pkg:npm/platform-tempo","source":"MAL-2026-4641"}],"products":null,"published":"2026-05-25","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-2026-4641/"}
