Malicious code in @vitemirrorte/element-plus-vite-cli (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

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.
