Installation invokes Playwright Chromium acquisition, including a root-only system-dependency attempt on Linux. Runtime is a configured, authenticated agent bridge with filesystem and command-oriented capabilities; explicit CLI service installation persists it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-09T08:27:14.155Z - **Finished:** 2026-08-09T08:28:18.887Z - **Download time:** 763 ms - **Static scan time:** 1874 ms - **AI review time:** 62093 ms - **Total time:** 64732 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation invokes Playwright Chromium acquisition, including a root-only system-dependency attempt on Linux. Runtime is a configured, authenticated agent bridge with filesystem and command-oriented capabilities; explicit CLI service installation persists it. - **Trigger:** npm postinstall; then CLI/runtime operation with configured scheduler credentials or explicit \`awsb service install\` - **Impact:** Large local execution and workspace-file control surface if its scheduler token/configuration is compromised. - **Evidence paths:** package.json, scripts/ensure-playwright-browser.mjs, dist/services/cli-commands.js, dist/index.js, dist/services/auto-register.js, dist/routes/file-browser.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T08:28:18.887Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** browser bootstrap, configured remote agent bridge, and explicit service persistence - **Rationale:** No concrete malicious chain was found, but install-time browser acquisition plus remote agent, filesystem, and service capabilities create material operational risk. Warn rather than block because persistence and scheduler use are explicit/configured. - **Files touched:** scripts/ensure-playwright-browser.mjs, dist/services/cli-commands.js, dist/services/startup-config-wizard.js, dist/services/auto-register.js, dist/routes/file-browser.js - **Network endpoints:** https://npmmirror.com/mirrors/playwright ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall downloads and installs Chromium; root Linux path requests Playwright system dependencies., CLI explicitly installs persistent systemd, launchd, or Windows services., Runtime exposes token-protected workspace file mutation and agent/terminal bridge functionality., Configured scheduler registration sends userKey and runtime bridge address to the configured server. - **Evidence against:** No hidden credential harvesting or unsolicited exfiltration found., Service persistence requires explicit \`awsb service install\`; it is not invoked by lifecycle hooks., Startup writes the package's own ~/.aws-bridge configuration, not foreign AI-agent controls., Computer-control routes are currently hard-disabled with HTTP 503. ## Public findings ### 1.
