The archive is not pinned or verified before execution. - **Trigger:** A user starts the Electron application while Obscura is not installed. - **Impact:** A compromise or replacement of the referenced release can run arbitrary native code as the user. - **Evidence paths:** package.json, src/main.js, src/agent/obscura.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T16:25:42.322Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic download, extraction, and execution of an unverified remote executable. - **Attack narrative:** On normal application startup, the package schedules an Obscura installation if its executable is missing. It fetches a ZIP from a GitHub latest-release URL, follows redirects, writes and expands the archive into the user profile, and later executes the extracted executable. There is no fixed artifact version, checksum, signature verification, or user approval gate. This creates a remote native-code execution path controlled by the external release source. - **Rationale:** The package automatically downloads and executes an unverified native payload during ordinary startup. This is a concrete remote-code-execution supply-chain path, despite no confirmed credential exfiltration. - **Files touched:** %APPDATA%\\beast\\obscura, %TMP%\\beast-obscura.zip, src/main.js, src/agent/obscura.js - **Network endpoints:** github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Normal application startup automatically starts an Obscura installation when its executable is absent., The installer downloads a latest-release executable archive from GitHub without a version pin or integrity check, extracts it, then runs it., The package has an automatic postinstall hook that invokes a repair script. - **Evidence against:** No static source evidence shows collected credentials or files being sent to an attacker., The postinstall repair targets the package's Electron dependency rather than an AI-agent control surface. ## Public findings ### 1.
