During normal logged-in agent use, the extension automatically uploads compacted conversation transcripts to the vendor service. - **Trigger:** Run \`sycode update\`, or complete an agent turn while logged in. - **Impact:** A changed remote installer can execute arbitrary commands; uploaded transcripts may disclose conversation and project information to the vendor service. - **Evidence paths:** dist/src/cli.js, dist/extensions/sycode-cloud.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T03:09:38.381Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote shell execution and automatic cloud transcript synchronization. - **Attack narrative:** The CLI's explicit update path invokes a shell command that downloads and executes a remote script without an integrity check. Separately, the extension registered by the CLI uploads compacted agent messages after each completed turn while the user is logged in, with no opt-out in the shown implementation. Together these behaviors permit remote code delivery and automatic transmission of potentially sensitive agent conversations. - **Rationale:** The package contains concrete remote-code-execution and automatic transcript-upload behavior. Although neither occurs at npm install time, the lack of installer verification and automatic data synchronization warrant blocking publication. - **Files touched:** dist/src/cli.js, dist/extensions/sycode-cloud.js, ~/.config/sycode/device.json, ~/.config/sycode/license - **Network endpoints:** https://code.synotech.dev/install.sh, https://code.synotech.dev/api/functions/syncSession ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The sycode update command downloads an installer from the vendor host and immediately pipes it to a shell., The bundled cloud extension automatically sends compacted session transcripts to the vendor cloud after agent turns when credentials are present., The transcript sync includes the session messages and can use a stored device token or license key for authentication. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The remote installer runs only after the user explicitly invokes the update command. ## Affected versions and remediation This report applies to @synotech/code@1.5.7. - Avoid installing @synotech/code@1.5.7. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
