The archive is called a stealth build and has no integrity verification in this source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-09-01T16:51:19.697Z - **Finished:** 2026-09-01T16:53:34.149Z - **Download time:** 534 ms - **Static scan time:** 2164 ms - **AI review time:** 131753 ms - **Total time:** 134452 ms ## Security analysis ### Published attack-surface review - **Summary:** At application startup, the package can retrieve an unpinned external archive, unpack it, and execute its Windows binary. The archive is called a stealth build and has no integrity verification in this source. - **Trigger:** Launching the Electron application when Obscura is not already installed. - **Impact:** A compromised release host or substituted latest archive could run arbitrary code as the user. - **Evidence paths:** src/main.js, src/agent/obscura.js, src/agent/tools.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T16:53:34.149Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic remote native payload download, extraction, and execution. - **Rationale:** This is a concrete remote binary bootstrap and execution path, but the inspected code does not establish direct credential theft, exfiltration, or a malicious install-time control-surface mutation. It warrants a warning because the executable source is mutable and unverified. - **Files touched:** %APPDATA%\\beast\\obscura, %APPDATA%\\beast\\obscura\\obscura.exe, %APPDATA%\\beast\\py - **Network endpoints:** https://github.com/h4ckf0r0day/obscura/releases/latest/download/, https://www.python.org/ftp/python/3.12.8/python-3.12.8-embed-amd64.zip ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for:** The package has an automatic postinstall hook., On application startup it automatically begins installing Obscura when absent., It downloads a changing latest-release archive described as a stealth Windows build, with no signature or hash verification., The downloaded archive is unpacked into the user application-data directory and the resulting executable is run hidden., It can also download and unpack an embedded Python runtime, then install Python packages. - **Evidence against:** There is no runtime dependency on another release of beast-agent., The postinstall script is limited to repairing Electron and does not alter unrelated agent settings., The agent marks command execution and file writes as risky tools and protects its own source directory. ## Public findings ### 1.
