The inventory is placed in the LLM system prompt and sent to the default anonymous remote provider on a subsequent prompt. - **Trigger:** User runs the \`nexus\` CLI and enters a prompt. - **Impact:** Unconsented disclosure of installed software, active applications, hostname, and username to a third-party endpoint. - **Evidence paths:** package.json, dist/cli/repl.js, dist/core/system/system-context.service.js, dist/core/config/config.schema.js, dist/core/llm/llm.service.js, dist/core/tools/desktop.tools.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T18:55:46.226Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent host inventory collection followed by remote LLM prompt transmission. - **Attack narrative:** The CLI deliberately performs a silent background host inventory at startup, collecting user/device identity and installed/running-app data. It inserts that data as hidden system context, while its default configuration uses an anonymous third-party LLM endpoint that serializes system content in a POST request. This is concrete, unconsented host-data exfiltration triggered by normal CLI use; the broad agent tool set increases downstream impact if remote model output is acted upon. - **Rationale:** Source confirms a normal-use path from stealthy host collection to a default third-party network request. The absence of an install hook does not mitigate this runtime data-exfiltration behavior. - **Files touched:** dist/cli/repl.js, dist/core/system/system-context.service.js, dist/core/config/config.schema.js, dist/core/llm/llm.service.js - **Network endpoints:** https://devtoolbox-api.devtoolbox-api.workers.dev/ai/generate ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** \`dist/cli/repl.js\` silently starts system inventory collection at CLI startup., \`dist/core/system/system-context.service.js\` enumerates installed and running applications plus hostname and username., \`dist/cli/repl.js\` injects that inventory into hidden chat history before handling prompts., Default config selects anonymous \`devtoolbox\` remote provider., \`dist/core/llm/llm.service.js\` POSTs system content to \`https://devtoolbox-api.devtoolbox-api.workers.dev/ai/generate\`., Agent exposes unrestricted file, shell, clipboard, screenshot, process, browser, and Docker tools. - **Evidence against:** \`package.json\` has only \`prepublishOnly\`; no install-time lifecycle hook., The collection activates when the user runs the CLI, not on package import/install., No evidence of encrypted staging, obfuscation, or persistence beyond package-owned configuration. ## Public findings ### 1.
