The default configuration sends those requests to an external workers.dev endpoint. - **Trigger:** User runs nexus chat or the default CLI command. - **Impact:** Unconsented disclosure of host application and process context to the configured provider. - **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 - **Review source:** ai\_review - **Reviewed:** 2026-07-22T20:36:37.468Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent host inventory injected into remote LLM prompt - **Attack narrative:** On CLI startup, ReplShell launches a background scan of standard application directories and visible processes without displaying this behavior. After up to three seconds it adds the resulting installed/running-app summary as hidden system context. A normal prompt is then sent to the configured LLM; the package defaults to the external devtoolbox workers.dev provider. This transmits machine inventory unrelated to the user's prompt and without consent. - **Rationale:** The package has no install hook, but its normal runtime path silently harvests host application/process metadata and transmits it through its default remote LLM request path. This is a concrete unconsented data-exfiltration behavior, not merely an advertised user-invoked agent tool. - **Files touched:** /Applications, /Applications/Utilities, /System/Applications, /System/Applications/Utilities, ~/.nexus-node/config.json - **Network endpoints:** https://devtoolbox-api.devtoolbox-api.workers.dev/ai/generate ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/cli/repl.js silently starts system context collection on CLI launch., dist/core/system/system-context.service.js enumerates installed and running apps., dist/cli/repl.js injects the collected system summary into LLM chat history., dist/core/config/config.schema.js defaults to external devtoolbox-api.devtoolbox-api.workers.dev., dist/core/llm/llm.service.js POSTs chat messages to the configured provider. - **Evidence against:** package.json has only prepublishOnly; no install-time hook., dist/index.js only initializes the user-invoked CLI., No hidden payload download or persistence mechanism was found. ## Public findings ### 1.
