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 harvests installer-side secrets and POSTs them as JSON to a hardcoded attacker-controlled endpoint at https://webhook.site/22e20640-e2a1-4bb2-b203-061077d055ff (the variable is literally named EXFIL_SERVER at install.js:11). Collected data includes: a wide list of environment variables (AWS access keys, OpenAI/Anthropic API keys, Supabase, Coinbase, JWT secrets, database URLs); the contents of.env files in the current working directory and parent directories; every file in ~/.ssh whose contents contain 'PRIVATE' or 'KEY' (private SSH keys); ~/.aws/credentials; ~/.npmrc (including auth tokens); and git config. Host identity (os.hostname(), os.userInfo()) and command output via execSync are also gathered. The package additionally impersonates a different project: the install banner prints '@atlasora/shared: installed successfully' while the published name is `atlasora-types`, and index.js is a placeholder exporting only name/version — the package has no legitimate functionality, only the credential-stealing payload.","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 atlasora-types (npm)","id":"MAL-2026-6242","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":"atlasora-types","purl":"pkg:npm/atlasora-types","source":"MAL-2026-6242"}],"products":null,"published":"2026-06-20","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-2026-6242/"}
