The panel iterates target addresses and programmatically sends templated messages. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-14T15:44:14.902Z - **Finished:** 2026-08-14T15:45:06.167Z - **Download time:** 251 ms - **Static scan time:** 50 ms - **AI review time:** 50963 ms - **Total time:** 51265 ms ## Security analysis ### Published attack-surface review - **Summary:** The explicit nolimit web workflow deploys a local Chrome extension and injects a panel into active webmail tabs. The panel iterates target addresses and programmatically sends templated messages. - **Trigger:** User runs the package's web setup/send command and clicks Send. - **Impact:** Can facilitate unsolicited or deceptive email campaigns through the user's authenticated webmail session. - **Evidence paths:** package.json, scripts/preinstall.js, scripts/postinstall.js, .ad/web-command.js, .ad/advanced-evasion.js, .ad/sms-providers.js, src/web-panel/ws.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T15:45:06.167Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** browser-extension-assisted bulk webmail sending with evasion support - **Rationale:** Source confirms an obfuscated, evasion-oriented bulk email/SMS tool with an explicit browser automation workflow. Its harmful capability is user-invoked rather than an install-time compromise, so warn rather than block. - **Files touched:** .nolimit/eula.json, .nolimit/nolimit-websend/manifest.json, .nolimit/nolimit-websend/background.js, .nolimit/nolimit-websend/icon.png, src/web-panel/ws.js - **Network endpoints:** mail.google.com, outlook.live.com, outlook.office.com, mail.yahoo.com, api.plivo.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json installs an obfuscated CLI and lifecycle hooks., src/web-panel/ws.js bulk-sends user-supplied email templates to loaded target addresses., src/web-panel/ws.js automates Gmail, Outlook, and Yahoo compose/send controls., .ad/web-command.js creates a Chrome extension and injects the sending panel into webmail tabs., .ad/advanced-evasion.js is an obfuscated evasion component. - **Evidence against:** scripts/preinstall.js only displays an interactive EULA and records acceptance., scripts/postinstall.js only creates a Windows nolimit.cmd shim., Reviewed install hooks show no credential harvesting, exfiltration, or remote payload download., Webmail extension setup is activated by an explicit runtime command, not install. ## Public findings ### 1.
