OpenSSF/OSV Malicious Advisory
imported 3mo ago · by OpenSSF/OSVOpenSSF/OSV advisory MAL-2026-5917 confirms this npm version as malicious.
Independent LPM AI assessment
SuspiciousIndependent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.
This is a browser proxy application with unsolicited third-party runtime loading and opaque code, not a confirmed npm malware chain. Block-level malicious intent is not established, but the remote traffic-control surface warrants a warning.
Independent scan evidence
public snapshot- `index.html` loads third-party `https://c.vipersfutbol.com/script.js` at page load.
- `assets/boot-CVPGRFHh.js` registers root service worker `j6k3y8.js`.
- `assets/boot-CVPGRFHh.js` configures proxy traffic through `wss://21baseballacademy.com/fairs/`.
- `ct1tl/pap3do.js` intercepts routed requests and loads the bundled WASM proxy runtime.
- `assets/ChatPage-zoA8Z6RX.js` is heavily obfuscated and makes runtime fetch/WebSocket calls.
- `package.json` has no preinstall, install, postinstall, bin, or Node execution hook.
- No source evidence of filesystem, environment, credential, wallet, or clipboard harvesting.
- No confirmed exfiltration payload or destructive action was found.
- The service-worker/WASM components form a coherent browser proxy implementation rather than a hidden npm install-time payload.
