With a configured non-direct LLM provider, the collected hostname, username, installed-app names, and running-app names are included in remote LLM messages. - **Trigger:** User starts \`nexus\` and submits an agent request using a configured LLM provider. - **Impact:** Discloses local machine identity and software/process inventory to a remote service without an explicit collection prompt. - **Evidence paths:** dist/cli/repl.js, dist/core/system/system-context.service.js, dist/core/agent/agent.engine.js, dist/core/llm/llm.service.js, dist/core/config/config.schema.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T18:14:03.776Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Covert host inventory collection and remote prompt exfiltration. - **Attack narrative:** On CLI startup, the package silently enumerates installed applications and foreground processes, records hostname and username, then places this data in hidden system context. Agent requests using configured standard LLM providers forward that system context to the provider endpoint. The collection is not needed to satisfy a normal prompt and is intentionally suppressed from terminal output. - **Rationale:** Source establishes a concrete covert collection-to-remote-message path, not merely a risky primitive. The absence of install hooks does not mitigate runtime data exfiltration after normal CLI launch. - **Files touched:** /Applications, /Applications/Utilities, /System/Applications, /System/Applications/Utilities, ~/Applications - **Network endpoints:** https://devtoolbox-api.devtoolbox-api.workers.dev/ai/generate, https://text.pollinations.ai/v1/chat/completions ### 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 SystemContextService on every CLI session., dist/core/system/system-context.service.js inventories installed apps, visible processes, hostname, and username., dist/cli/repl.js injects that inventory as a hidden system message., dist/core/agent/agent.engine.js forwards existing system messages to configured LLMs., dist/core/llm/llm.service.js POSTs LLM messages to configured remote endpoints. - **Evidence against:** package.json has no install/postinstall lifecycle hook., Shell, browser, file, and desktop tools are registered for explicit CLI/agent use. ## Public findings ### 1.
