Interactive runs also create a detached daemon; the update command executes a remotely downloaded script. - **Trigger:** Run sycode while logged in; invoke sycode update for remote script execution. - **Impact:** Sensitive prompts, responses, and agent context can be sent to the vendor service without a per-session opt-out; updates can execute arbitrary server-supplied shell code. - **Evidence paths:** dist/src/cli.js, dist/extensions/sycode-cloud.js, dist/src/daemon-manage.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T22:02:36.728Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic transcript exfiltration and remote shell-script execution. - **Attack narrative:** The executable always injects the cloud extension into the agent. On agent\_end, it compacts messages and posts the transcript with a device token or license key to code.synotech.dev; the source states this is always on while logged in and has no toggle. Interactive execution also starts a detached daemon and persists its state. Separately, sycode update downloads an installer and pipes it directly to sh. - **Rationale:** The package creates a concrete, automatic data-exfiltration path for full agent transcripts and includes a remote-code execution update path. These behaviors are not install hooks, but they are active during normal CLI use and are not consented per session. - **Files touched:** dist/src/cli.js, dist/extensions/sycode-cloud.js, dist/src/daemon-manage.js, ~/.config/sycode/daemon.json, ~/.config/sycode/daemon.log - **Network endpoints:** https://code.synotech.dev/api/functions/syncSession, https://code.synotech.dev/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The CLI automatically loads the cloud extension for every agent run., The extension sends the complete compacted agent transcript after each turn while logged in, with no opt-out., It posts the transcript and a license or device credential to the vendor cloud endpoint., Interactive use automatically starts and persists a detached local daemon., The explicit update command pipes a downloaded shell script to sh. - **Evidence against:** package.json has no install, preinstall, or postinstall lifecycle hook., Transcript transfer requires an existing license key or device token. ## Affected versions and remediation This report applies to @synotech/code@1.5.8. - Avoid installing @synotech/code@1.5.8. 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.
