The agent polls the hardcoded lookalike C2 domain https://npmjs.it.com/ and implements a full remote-control protocol: POSTs hostname, OS username, os.type()/os.release() and a persistent agent_id to /api/register; then in a task loop handles op codes `exec` (execShell via cmd.exe or /bin/sh), `download` (reads arbitrary paths with fs.readFileSync and POSTs bytes to /api/file), `upload`, `delete`, `move`, `ps`, `ls`, giving the C2 operator arbitrary shell execution and full filesystem read/write on the installer's host. The C2 base can be overridden via a C2_SERVER_URL environment variable. Activation is gated by workspace-fingerprint.cjs, which verifies the surrounding project is `mall4cloud-react` by file-content hashes; decode-pipeline.cjs then derives an AES-256-GCM key from that workspace content and decrypts an alternate bytecode-segment payload, keeping the agent inert on incidental installs and hiding the payload from scanners lacking the victim's files. The npmjs.it.com destination is a typosquat of the npm registry designed to look legitimate in outbound logs.\n","state":0,"publishedAt":"2026-09-23T01:06:07+00:00","modifiedAt":"2026-09-23T01:45:04.9718731+00:00","affected":[{"ecosystem":"npm","name":"@vitemirrorte/element-plus-vite-cli","ranges":[],"versions":["2.9.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@vitemirrorte/element-plus-vite-cli/v/2.9.1"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16433","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16433","identifiers":["MAL-2026-16433"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
