AI Security Review

scanned 3h ago · by lpm-firewall-ai

Opening index.html executes a third-party script from c.vipersfutbol.com under the page origin. The package also ships obfuscated browser code and a proxy/service-worker stack capable of intercepting routed browser requests and handling cookies.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

A user opens the packaged index.html in a browser.

Impact

Remote operator can change code executed by the package at runtime and interact with data available to that page origin.

Mechanism

Unpinned remote JavaScript execution plus obfuscated proxy runtime.

Attack narrative

The package does not execute during npm installation, but its declared browser entrypoint automatically imports JavaScript from c.vipersfutbol.com without an integrity constraint. That remote server can replace the executed payload after publication. The local application bundles are deliberately obfuscated and include a proxy/service-worker framework that routes requests and synchronizes cookies, increasing the available browser control surface. This establishes a concrete runtime remote-code-execution path rather than a scanner-only suspicion.

Rationale

Direct source inspection confirms an automatic, unpinned third-party script loader in the browser entrypoint alongside obfuscated request-interception code. The absence of npm lifecycle hooks limits the trigger to browser use but does not remove the concrete remote execution behavior.

Decision evidence

public snapshot

AI called this Malicious at 95.0% confidence as Malware with low false-positive risk.

Evidence for block

index.html automatically loads unsandboxed code from c.vipersfutbol.com.
assets/ChatPage-zoA8Z6RX.js and assets/index-CJm_PfL2.js are heavily obfuscated runtime bundles.
ct1tl/pap3do.js and j6k3y8.js implement proxy/service-worker interception with cookie handling.
The external script has no integrity pinning or package-aligned purpose.

Evidence against

package.json declares no preinstall, install, postinstall, or other lifecycle hooks.
package.json main is index.html, so no Node import-time entrypoint is declared.
