@vitemirrorte/element-plus-vite-clinpm
@vitemirrorte/element-plus-vite-cli is a confirmed malicious npm package (MAL-2026-16433) that steals credentials and exfiltrates sensitive data (malicious version 2.9.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @vitemirrorte/element-plus-vite-cli (npm)
What this malware does
On npm install, package.json's postinstall runs postinstall-run.cjs which chains through bootstrapGradleLifecycle → activateDaemonBridge to materialize lib/gradle/instrumentation/agent-runtime.source.mjs into ~/.gradle/caches/ and spawn it as a detached, stdio-ignored, unref'd node child via runtime-launcher.cjs, writing a PID file so the process persists beyond install. 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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @vitemirrorte/element-plus-vite-cli (version 2.9.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @vitemirrorte/element-plus-vite-cli across your stack and pipelines.
If you installed it — respond
@vitemirrorte/element-plus-vite-cli is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @vitemirrorte/element-plus-vite-cli was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @vitemirrorte/element-plus-vite-cli before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
