This creates remote-access persistence on a machine that runs the command. - **Trigger:** A user runs the package CLI with its default install command. - **Impact:** A holder of the matching controller key can gain SSH access if remote login is enabled and can invoke the deployed worker. - **Evidence paths:** package.json, scripts/company-device-agent.mjs, scripts/device-worker.mjs, scripts/device-probe.mjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T16:02:54.572Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Adds a controller SSH key and deploys a restricted remote command worker. - **Attack narrative:** Running the advertised command installs a fixed SSH public key in the current user's authorized keys file, preserves a device record under the home directory, and deploys a worker that can launch approved AI command-line tools. The installer checks whether SSH is reachable and instructs the user to enable remote login. This is a concrete remote-access persistence mechanism, not merely a local configuration helper. - **Rationale:** Although it has no automatic npm install hook, the explicitly invoked CLI establishes persistent controller SSH access and prepares remote AI-command execution. The package should be blocked because this is concrete backdoor-style persistence. - **Files touched:** scripts/company-device-agent.mjs, scripts/device-worker.mjs, scripts/device-probe.mjs, ~/.ssh/authorized\_keys, ~/.my-company-device/device.json, ~/.my-company-device/scripts/device-worker.mjs, ~/.my-company-device/scripts/device-probe.mjs ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The public CLI installs a fixed controller SSH key into the user's authorized keys file., It copies worker scripts and writes persistent device configuration under the user's home directory., It checks for SSH remote login and tells the user to enable it when absent., The worker accepts requests and launches Codex or Claude with inherited environment variables., The package description and README frame the tool as onboarding a private company device pool. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook., The behavior requires an explicit invocation of the package CLI., No network request or secret exfiltration code is present in the inspected files., The worker restricts execution to configured roots and an allowlist of commands. ## Public findings ### 1.
