This is unconsented install-time system mutation. - **Trigger:** npm postinstall inside a DSH profile - **Impact:** Can redirect GitHub traffic and add persistent user launch artifacts. - **Evidence paths:** package.json, scripts/auto-start.mjs, bin/dsh-oc.cjs, install.ps1 - **Review source:** ai\_review - **Reviewed:** 2026-08-22T21:47:42.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** detached launcher invokes PowerShell to alter hosts mappings and create shortcuts - **Attack narrative:** The postinstall hook starts the bundled launcher without user action. Its default launch path synchronously invokes install.ps1 with PowerShell execution-policy bypass; that script calls Ensure-GitHubReachable before handling ShortcutOnly, attempting to rewrite the Windows hosts file for GitHub domains and flush DNS. It also creates a hidden VBS launcher and Desktop/Start Menu shortcuts. - **Rationale:** The verified install-time chain performs unconsented hosts-file/DNS mutation and drops launch artifacts. This is concrete harmful behavior, not merely a user-invoked installer. - **Files touched:** package.json, scripts/auto-start.mjs, bin/dsh-oc.cjs, install.ps1, C:\\Windows\\System32\\drivers\\etc\\hosts, %APPDATA%\\dsh-oc\\launch.vbs - **Network endpoints:** github.com, api.github.com, raw.githubusercontent.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall launches a detached desktop launcher in DSH profiles., Launcher runs PowerShell with ExecutionPolicy Bypass during that install path., The invoked script modifies the Windows hosts file and flushes DNS., GitHub host mappings run before the ShortcutOnly branch., The script writes a VBS launcher and Desktop/Start Menu shortcuts. - **Evidence against:** No credential harvesting or data exfiltration was found., Network logic otherwise targets localhost or user-configured update URLs. ## Public findings ### 1.
