Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The flagged credential-exfiltration claim is not supported: the observed backup traffic goes to EmbarkAI's own service and uploads an encrypted envelope. The package can still create that server-managed wallet backup automatically after sign-in, so warn users about the sensitive default behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-31T00:18:21.713Z - **Finished:** 2026-10-31T00:19:44.404Z - **Download time:** 1025 ms - **Static scan time:** 7420 ms - **AI review time:** 74244 ms - **Total time:** 82691 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Sign-in can automatically create a server-managed wallet keyshare backup when none exists, without a separate backup confirmation. - **Trigger:** Successful sign-in with iframe authentication and an available keyshare, when no server backup exists. - **Impact:** A sensitive wallet keyshare is enrolled in the vendor's server-managed recovery flow without a distinct backup action from the user. - **Evidence paths:** dist/index.js, dist/iframe/main.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T00:19:44.404Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Post-login synchronization calls \`ensureServerBackup\`; the iframe can create an encrypted Basic envelope and PUT it to EmbarkAI's vault using a bearer resource token. - **Rationale:** The flagged credential-exfiltration claim is not supported: the observed backup traffic goes to EmbarkAI's own service and uploads an encrypted envelope. The package can still create that server-managed wallet backup automatically after sign-in, so warn users about the sensitive default behavior. - **Files touched:** dist/index.js, dist/iframe/main.js - **Network endpoints:** https://api.embarkai.io/vault/v1/shares/me, https://api.embarkai.io/tss/api/auth/backup/recovery-dek/wrap ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After sign-in, the UI flow calls \`syncServerBackupAfterLogin\` automatically., That sync calls \`ensureServerBackup\` with the user's access token., Iframe authentication allows Basic backup creation; the creation path proceeds unless \`allowCreate\` is false., The Basic backup path encrypts the keyshare into an envelope, then PUTs that envelope to the vault with a bearer resource token. The vault is hosted at \`api.embarkai.io\`. - **Evidence against:** The backup flow sends data to the package's own EmbarkAI service, consistent with its wallet and MPC key-management purpose., The uploaded keyshare is encrypted into an envelope; the source does not show credentials being sent to an unrelated host., The manifest declares no lifecycle scripts, and the automatic backup is tied to sign-in rather than package installation. ## Affected versions and remediation This report applies to @embarkai/ui-kit@0.6.11. - Review the evidence and your use of @embarkai/ui-kit@0.6.11 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
