No checksum, signature, or fixed release is verified in this path. - **Trigger:** Application startup when Obscura is not already installed. - **Impact:** A changed or compromised upstream release can execute arbitrary native code under the user's account. - **Evidence paths:** package.json, src/main.js, src/agent/obscura.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T19:40:14.768Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic download, extraction, and execution of a remote stealth browser binary. - **Attack narrative:** When the Electron entry point starts, it schedules installation of Obscura if absent. The installer fetches a stealth Windows archive from a mutable third-party GitHub latest-release endpoint, writes and extracts it under the user's application-data directory, and later executes obscura.exe. The code provides no source pinning or integrity verification, so the remote release controls native code executed on the host. - **Rationale:** The package has a concrete unconsented remote native-code execution path at normal startup. This exceeds ordinary agent functionality and creates a supply-chain payload channel. - **Files touched:** %APPDATA%\\beast\\obscura, %TEMP%\\beast-obscura.zip, %APPDATA%\\beast\\obscura\\obscura.exe - **Network endpoints:** https://github.com/h4ckf0r0day/obscura/releases/latest/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package entry point automatically starts the Obscura installer when its executable is absent., The installer downloads a third-party stealth browser archive from a moving GitHub latest-release URL and expands it into the user's application data directory., The downloaded executable is later launched as a child process., The manifest identifies src/main.js as the runtime entry point. - **Evidence against:** The install lifecycle hook is limited to repairing the Electron dependency rather than configuring an external AI-agent surface., The source presents Obscura as a web-search component, but that does not provide consent for automatic remote native-code installation. ## Public findings ### 1.
