Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. When the CLI is run, it sends telemetry containing all tracked command options, including authentication tokens, to PostHog. This is concrete credential exfiltration rather than ordinary aggregate telemetry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T15:13:21.158Z - **Finished:** 2026-09-13T15:15:02.290Z - **Download time:** 511 ms - **Static scan time:** 3081 ms - **AI review time:** 97540 ms - **Total time:** 101132 ms The recorded confidence comes from the underlying analysis.

This is concrete credential exfiltration rather than ordinary aggregate telemetry. - **Trigger:** Running \`blokctl login --token\` or \`blokctl profile --token\`. - **Impact:** Login and Prometheus authentication tokens, command errors, and host-identifying system data can be disclosed. - **Evidence paths:** dist/services/posthog.js, dist/services/commander.js, dist/commands/login/index.js, dist/commands/profile/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T15:15:02.290Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unsanitized command-option telemetry to an external analytics service. - **Attack narrative:** The CLI constructs analytics by default and wraps commands in a tracker that copies their entire option object into a PostHog event. The login command accepts a token option and forwards that object unchanged; the profile command does the same for a Prometheus token. The telemetry client also sends hostname-derived identity and system properties. Consequently, a normal user-invoked authentication command can transmit credentials to the external analytics endpoint. - **Rationale:** Source directly connects token-bearing command options to a default external telemetry capture path. The absence of npm lifecycle hooks does not mitigate this runtime credential disclosure. - **Files touched:** dist/services/posthog.js, dist/services/commander.js, dist/commands/login/index.js, dist/commands/profile/index.js, $HOME/.blok/blokctl.json - **Network endpoints:** https://us.i.posthog.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Default telemetry sends command arguments and errors to PostHog., The login command passes its token-bearing options into that telemetry path., The profile command likewise forwards a Prometheus authentication token., Telemetry includes a stable hostname-derived identifier and runs unless an unrelated opt-out variable is set., Command execution tracking forwards its arguments to the analytics service. - **Evidence against:** package.json contains no npm preinstall, install, postinstall, or prepare hook., No self-dependency on blokctl is declared. ## Affected versions and remediation This report applies to blokctl@2.3.0. - Avoid installing blokctl@2.3.0. 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.
