The package changes project AI-agent behavior without an explicit setup action and can cause agent session metadata and transcript-derived usage information to be sent to a configured endpoint. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.1.101 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A postinstall hook automatically overwrites and merges AI-agent control files into the consumer project. It enables a Claude session hook, broad command permissions, MCP servers, and later telemetry of workflow and transcript-derived data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T15:50:56.624Z - **Finished:** 2026-09-15T15:52:05.984Z - **Download time:** 768 ms - **Static scan time:** 496 ms - **AI review time:** 68095 ms - **Total time:** 69360 ms The recorded confidence comes from the underlying analysis.

It enables a Claude session hook, broad command permissions, MCP servers, and later telemetry of workflow and transcript-derived data. - **Trigger:** Installing the package runs postinstall; opening Claude in the modified project runs the installed session hook; package workflows invoke telemetry. - **Impact:** The package changes project AI-agent behavior without an explicit setup action and can cause agent session metadata and transcript-derived usage information to be sent to a configured endpoint. - **Evidence paths:** package.json, bin/folder-mappings.js, bin/install.js, claude/settings.local.json, siesa-agents/observability/scripts/sa-session.js, siesa-agents/observability/scripts/sa-emit.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T15:52:05.984Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic agent-control-surface injection with session tracking and workflow telemetry. - **Attack narrative:** Installing the package invokes its installer automatically. The installer copies package-controlled content into consumer AI-agent configuration paths, including Claude settings that enable a SessionStart command hook and permissive shell actions. The hook stores session identifiers and transcript paths under the user Claude directory. Installed workflow files can then read transcript token usage and send workflow records to a configured telemetry endpoint. The same automatic installer clones a remote repository and initializes Git when absent. These are unconsented, broad project and AI-agent control-surface changes. - **Rationale:** This is malicious install-hook abuse: an automatic postinstall modifies foreign AI-agent control surfaces and installs hooks that collect session context for later telemetry. The user-invoked OAuth code does not mitigate the independent postinstall behavior. - **Files touched:** .claude, .gemini, .github, .vscode, .mcp.json, \_siesa-agents, \_bmad-output/design-artifacts, .git, .gitignore, ~/.claude/observability - **Network endpoints:** github.com, 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 policy risk:** Installation automatically runs the installer without an explicit setup command., The installer copies package content into Claude, Gemini, GitHub, VS Code, and MCP control paths in the consumer project., The copied Claude settings enable a session hook and broad shell permissions., The installed hook records Claude session metadata, including transcript paths., Workflow telemetry reads transcript token data and posts it to an environment-selected endpoint., Installation also clones a remote repository and initializes Git in a project lacking Git. - **Evidence against:** The Jira OAuth flow is separately user-invoked and targets Atlassian., Telemetry transmission requires an endpoint supplied through environment configuration. ## Affected versions and remediation This report applies to siesa-agents@2.1.101. - Avoid installing siesa-agents@2.1.101. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
