AI Security Review

scanned 11d ago · by lpm-firewall-ai

The package entrypoint collects browser authentication and storage data and posts it to an external endpoint. This is active data exfiltration when the entrypoint runs in a browser-like environment.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Loading the package entrypoint where document storage is available.

Impact

Browser session credentials and application data may be disclosed to the external operator.

Mechanism

The code reads cookies, local storage, and session storage, serializes them, and sends them with fetch POST requests.

Attack narrative

When the declared entrypoint loads in a browser context, it checks for cookies and populated browser storage. It posts each available value to an external challenge-domain endpoint using fetch. Cookies can contain session credentials, while local and session storage can contain tokens and application data.

AI rationale

The active entrypoint implements unsolicited browser credential and data collection followed by transmission to an unrelated external endpoint. This is concrete credential and data exfiltration behavior.

Advisory

my-skibidi@1.0.2 contains top-level code in its main module that unconditionally POSTs `document.cookie` to the hardcoded remote endpoint https://c-b34596407b6d47d6.dgactf-challs.site/addPost via a `sendPost(...)` call. Any downstream web application that bundles this package will, when loaded in a user's browser, transmit that user's cookies and session data to the external host. The destination is not a first-party service and is not caller-configurable; the exfiltration runs as a side effect of loading the module. The package's declared functionality does not require reading or transmitting cookies, and no consent gate or configuration controls the behavior. ## Source: ghsa-malware (47126398a61b320eb7bbad1b71461843e4609e46f5137d735ea3d15d976c7f46) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
