It enables RDP and inbound firewall rules, provisions an Administrator/Remote Desktop Users account, stores credentials, hides the account from the sign-in screen, and disguises its service as Windows infrastructure. These changes occur without an explicit user command and establish concealed remote-access capability. - **Rationale:** This is concrete malicious install-time behavior: it modifies Windows security controls and creates concealed privileged remote access. Lack of observed exfiltration does not mitigate the unconsented persistence and access setup. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, payload/rdpwrap.ini, config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall invokes the installer automatically., Install enables RDP/firewall, installs payloads, then provisions an account., Account setup adds the target to Administrators and Remote Desktop Users., Code disguises the installed service as Windows infrastructure and hides protected folders. - **Evidence against:** No network endpoint or exfiltration code was found in inspected JavaScript., Payload checksums are verified before execution. ## Public findings ### 1.

Public source snippet (untrusted): ```text path = payload/bikli-cli-installer.exe kind = native_binary sizeBytes = 11639800 magicHex = [redacted] ``` ### 8. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 9. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() npm postinstall invokes the installer automatically. Public source snippet (untrusted): ```json "scripts": { "postinstall": "node bin/biklimaster.js install --postinstall", "test": "node bin/biklimaster.js self-test" ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** bin/biklimaster.js - **Public source:** [View source]() Install enables RDP/firewall, installs payloads, then provisions an account. Public source snippet (untrusted): ```javascript function install() { requireWindows(); if (!isAdministrator()) return elevateAndRun('install'); verifyPayload(); installBikli(); const serviceProvisioned = ensureBikliService(); if (serviceProvisioned) disguiseBikli(); try { setupBikliKey(); } catch (error) { console.error(`Warning: Bikli key setup skipped: ${error.message}`); console.error('Run "biklitool setup-key" later to retry.'); } console.log('Installing or updating Bikli Wrapper silently...'); const wrapper = runWrapper(['install', '--elevated']); if (wrapper.stdout.trim()) console.log ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** sbman - **Ecosystem:** npm - **Version:** 1.0.4 - **License:** BSD-3-Clause - **Version published:** 2026-08-15T10:31:29.229Z - **Package first seen:** 2026-08-16T09:20:59.806Z - **Package last seen:** 2026-08-16T09:24:49.377Z - **Known versions:** 5 - **Latest version:** 1.0.5 - **Appeal under review:** No - **Description:** Internal Windows installer for Bikli CLI and Bikli Wrapper - **Keywords:** bikli, rdp, vpn, windows, installer - **Runtime engines:** node: \>=18 - **Supported OS:** win32 - **Artifact files:** 10 - **Artifact unpacked size:** 13,727,532 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
