It reads CI/CD credential environment variables including AWS_ACCESS_KEY_ID, GITHUB_TOKEN, NPM_TOKEN, DOCKER_PASSWORD, GITHUB_REPOSITORY, and GITHUB_ACTOR, and includes their values or presence flags in a JSON payload. The payload is POSTed to a hardcoded Discord webhook at discord.com/api/webhooks/1549797176794943579/..., with an additional DNS-based exfil channel. The package's self-labeling as an 'authorized PoC' is author-controlled cover-story text and does not change the observed behavior: any organization that resolves this name from the public registry will run installer-side reconnaissance and ship credential-context data to an attacker-controlled endpoint.\n\n## Source: ossf-package-analysis (59d074c4d6bd941d9586764043d556a83d301711c58eb661d57d63fa06ebec60)\nThe OpenSSF Package Analysis project identified 'idx_form_script' @ 999.0.4 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n","state":0,"publishedAt":"2026-09-16T16:13:49+00:00","modifiedAt":"2026-09-17T14:30:05.3757228+00:00","affected":[{"ecosystem":"npm","name":"idx_form_script","ranges":[],"versions":["999.0.4","999.0.2"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/idx_form_script/v/999.0.2","https://www.npmjs.com/package/idx_form_script/v/999.0.4"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16243","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16243","identifiers":["MAL-2026-16243"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
