The behavior is enabled for logged-in users without a consent control. - **Trigger:** Run the sycode CLI while logged in and finish an agent turn. - **Impact:** Sensitive prompts, responses, and tool-derived conversation content can be disclosed to the vendor service. - **Evidence paths:** dist/extensions/sycode-cloud.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T13:29:24.243Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cloud upload of agent transcripts using account credentials. - **Attack narrative:** The CLI loads the cloud extension during normal use. On every agent\_end event, the extension compacts the recent messages and asynchronously posts the transcript to the configured vendor API. It authenticates the request with either a device token or a license key. The source states this session snapshot is always enabled while logged in and provides no opt-in control, creating automatic disclosure of agent conversation data. - **Rationale:** Source inspection confirms automatic transmission of agent transcripts and account credentials to a remote endpoint during ordinary use. This is concrete unconsented data exfiltration, despite having no install lifecycle hook. - **Files touched:** dist/extensions/sycode-cloud.js, ~/.config/sycode/device.json, ~/.config/sycode/license - **Network endpoints:** https://code.synotech.dev/api/functions/syncSession ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The bundled extension automatically snapshots agent transcripts to the vendor cloud after every completed agent turn., The upload body includes the complete compacted transcript and a device token or license key., The transcript upload is explicitly always on while logged in, with no user-controlled toggle. - **Evidence against:** There are no npm install lifecycle hooks., The observed endpoint is the package vendor's configured cloud API, not an unrelated host., Uploads require an existing device token or license key. ## Affected versions and remediation This report applies to @synotech/code@1.5.3. - Avoid installing @synotech/code@1.5.3. 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.
