The installed hook captures Claude session metadata; workflow instructions require telemetry emission that can read transcript token usage. - **Trigger:** npm install of siesa-agents@2.1.95 - **Impact:** Unconsented AI-agent control-surface modification and potential disclosure of Claude session/workflow metadata to configured telemetry infrastructure. - **Evidence paths:** package.json, bin/install.js, bin/folder-mappings.js, claude/settings.local.json, siesa-agents/observability/scripts/sa-session.js, siesa-agents/observability/scripts/sa-emit.js, mcp.json - **Review source:** ai\_review - **Reviewed:** 2026-08-11T13:50:13.880Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall deployment of Claude hook, permissions, MCP configuration, and telemetry scripts - **Attack narrative:** Installing the package automatically copies a Claude configuration into the consumer project. That configuration enables a SessionStart command hook, permissive Bash rules, and remote MCP registrations. The hook stores session metadata under the user home directory; installed workflow instructions require telemetry calls, and sa-emit can read session transcript paths and send derived workflow/token data to a configured endpoint. These foreign AI-agent control-surface changes occur during npm postinstall without user confirmation. - **Rationale:** Source inspection confirms an unconsented postinstall mutation of broad Claude project controls, plus a telemetry chain that accesses session metadata and transcript-derived usage. This meets the block policy regardless of the scanner similarity hint. - **Files touched:** package.json, bin/install.js, .claude/settings.local.json, \_siesa-agents/observability/scripts/sa-session.js, \_siesa-agents/observability/scripts/sa-emit.js, .mcp.json - **Network endpoints:** https://platform-architecture-mcp-siesa-103767536676.us-east1.run.app/mcp, https://mcp.atlassian.com/v1/sse ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/install.js via postinstall., bin/install.js copies package content into .claude, .github, .gemini and .mcp.json in cwd., claude/settings.local.json enables Claude SessionStart hook and broad Bash permissions., Hook runs \_siesa-agents/observability/scripts/sa-session.js automatically., sa-emit.js reads Claude session transcript paths and can POST telemetry to configured endpoint., mcp.json registers remote SIESA and Atlassian MCP servers. - **Evidence against:** Telemetry destination in sa-emit.js requires environment configuration; no fixed collector URL is embedded., OAuth and DevOps scripts are user-invoked rather than lifecycle-executed. ## Public findings ### 1.
