The npm account amel10 published alexa-cybertron-team-code-review-agent and 9 similar packages within two minutes on 2026-09-30, all with the same setup.js.\n\n---\n_-= Per source details.

The package name namespaces an internal-sounding team (`alexa-cybertron-team-...`) and is published at version 100.0.0, a shape consistent with a dependency-confusion probe designed to win resolution against a private internal package and report back which victim environments installed it. There is no relationship between the advertised titleCase functionality and the install-time host reconnaissance beacon.\n","state":0,"publishedAt":"2026-09-30T07:11:21+00:00","modifiedAt":"2026-10-04T23:45:17.9639428+00:00","affected":[{"ecosystem":"npm","name":"alexa-cybertron-team-code-review-agent","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["100.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/alexa-cybertron-team-code-review-agent","https://www.npmjs.com/package/alexa-cybertron-team-code-review-agent/v/100.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17430","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17430","identifiers":["MAL-2026-17430"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
