On npm postinstall, the package mutates the consuming project's Claude Code extension surface. It installs its own prefixed skill and adds a scoped import to .claude/CLAUDE.md; no exfiltration or remote execution was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 92.0% - **Started:** 2026-08-08T11:30:19.495Z - **Finished:** 2026-08-08T11:31:03.026Z - **Download time:** 512 ms - **Static scan time:** 51 ms - **AI review time:** 42966 ms - **Total time:** 43531 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package mutates the consuming project's Claude Code extension surface. It installs its own prefixed skill and adds a scoped import to .claude/CLAUDE.md; no exfiltration or remote execution was found. - **Trigger:** npm install of @ploomescrm/bridge - **Impact:** Automatically activates package-supplied agent instructions in the consumer project. - **Evidence paths:** package.json, scripts/setup.mjs, ai-extensions/CLAUDE.md, ai-extensions/skills/use-bridge/SKILL.md, dist/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-08T11:31:03.026Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall propagation of bundled Claude Code extensions - **Rationale:** This is an unconsented install-time mutation of an AI-agent control surface, creating lifecycle risk. Source inspection found it to be first-party, scoped extension setup rather than concrete malicious behavior. - **Files touched:** .claude/skills/ploomes-bridge-use-bridge, .claude/CLAUDE.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall: node scripts/setup.mjs., scripts/setup.mjs copies bundled extensions into consumer .claude categories., scripts/setup.mjs rewrites a marked block in consumer .claude/CLAUDE.md., ai-extensions/ contains an auto-activated Claude Code skill. - **Evidence against:** Copied content is package-specific bridge documentation, not a payload., No network endpoint, credential harvesting, shell execution, eval, or dynamic loading found., Cleanup targets only entries prefixed ploomes-bridge-., dist/index.mjs is a local iframe/WebView messaging library. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/setup.mjs ``` ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** scripts/setup.mjs - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L3: * postinstall — mirrors the extensions declared by the `ploomesAiExtensions` L4: * manifest in package.json into a consumer project's `.claude/`, each item L5: * prefixed so it coexists with the project's own content. Only acts when ... L8: * Claude Code only discovers skills that are direct children of L9: * `.claude/skills/` (i.e. `.claude/skills//SKILL.md`), so items are L10: * flattened with a prefix rather than nested under a namespace directory: ...

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 90.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 7. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 14 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @ploomescrm/bridge - **Ecosystem:** npm - **Version:** 1.1.0 - **License:** SEE LICENSE IN LICENSE.md - **Version published:** 2026-08-07T18:12:45.947Z - **Package first seen:** 2026-08-08T11:30:52.499Z - **Package last seen:** 2026-08-08T11:31:03.026Z - **Known versions:** 3 - **Latest version:** 1.1.2 - **Appeal under review:** No - **Description:** Bridge de comunicação tipado e \*\*agnóstico de transporte\*\* entre uma aplicação host e os apps que ela embute — um \`\\` no web, uma \`\\` no mobile. - **Maintainers:** hugo.ploomes, caio\_lopes, emanuel-ploomes - **Runtime engines:** node: \>=18.0.0, pnpm: \>=8.0.0 - **Artifact files:** 14 - **Artifact unpacked size:** 98,345 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
