notebooklm

The fragment appears to be a legitimate NotebookLM client implementation, not malware. It contains a significant credential-exposure risk in the fallback downloader because authenticated cookies are sent across unrestricted HTTP/HTTPS redirects. It also relies on callers to constrain the download URL and output path; untrusted values could cause SSRF-like behavior or arbitrary local file writes. The severity depends on whether these arguments and redirecting endpoints are attacker-controlled.

The fragment appears to be a utility that imports cookies for a NotebookLM-related workflow from a local Chrome profile and stores them on disk. This is inherently sensitive credential handling, but the fragment alone does not establish malicious intent or network exfiltration. Review of auth.js, cookie-store.js, and paths.js is required to determine whether cookies are safely accessed and stored, whether the path is controlled, and whether data is transmitted elsewhere.
