The injected panel sends supplied content to a supplied email list using the user's webmail session. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 90.0% - **Started:** 2026-08-13T23:43:54.812Z - **Finished:** 2026-08-13T23:45:11.380Z - **Download time:** 501 ms - **Static scan time:** 64 ms - **AI review time:** 76003 ms - **Total time:** 76568 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicit CLI setup creates a package-owned browser extension which injects code into an active webmail tab. The injected panel sends supplied content to a supplied email list using the user's webmail session. - **Trigger:** User runs nolimit web --setup, loads the generated extension, then runs nolimit web and clicks Send. - **Impact:** Can enable phishing or unsolicited bulk email from the operator's authenticated webmail account. - **Evidence paths:** package.json, .ad/web-command.js, src/web-panel/ws.js, scripts/preinstall.js, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T23:45:11.380Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** bulk webmail automation through a generated Chrome extension - **Rationale:** Warn for the concrete high-risk bulk-mail/browser-extension capability and obscured implementation. The lifecycle scripts do not establish malicious install-time behavior. - **Files touched:** .ad/web-command.js, src/web-panel/ws.js, .ad/x0.js, scripts/preinstall.js, scripts/postinstall.js - **Network endpoints:** https://oauth2.googleapis.com/device/code, https://graph.microsoft.com/v1.0/me/mailFolders/inbox/messages, https://dns.google/resolve ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** src/web-panel/ws.js injects a panel into Gmail, Outlook, and Yahoo and sends each supplied target., .ad/web-command.js builds a Chrome extension with broad host permissions and executes received panel code via Function., Obfuscated .ad/advanced-evasion.js and other runtime modules conceal bulk-mail functionality. - **Evidence against:** scripts/preinstall.js only records an interactive EULA acceptance; non-TTY installs exit., scripts/postinstall.js is Windows-only and creates a nolimit.cmd bin shim; no exfiltration found., Extension setup is invoked by the explicit nolimit web --setup command, not during installation. ## Public findings ### 1.
