It opens RDP, creates or enables a hidden administrator-capable account, and disguises its service as Microsoft. - **Trigger:** npm postinstall: node bin/biklimaster.js install --postinstall - **Impact:** Unauthorized persistent remote administrative access to the Windows host. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json - **Review source:** ai\_review - **Reviewed:** 2026-08-15T11:29:39.900Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Elevated RDP backdoor provisioning with account creation, firewall changes, concealment, and service impersonation - **Attack narrative:** Installation invokes an elevated installer that silently installs and starts a service, enables RDP on port 3389, weakens authentication and shadowing protections, creates or enables an account in Administrators and Remote Desktop Users, hides that account, and stores its credentials locally. The package also hides protected folders and rewrites executable identity fields to present as Microsoft svchost. These actions are automatically triggered by postinstall rather than an explicit user setup command. - **Rationale:** This is concrete, unconsented install-time remote-access persistence and concealment behavior. It merits blocking regardless of the absence of observed network exfiltration code. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, payload/rdpwrap.ini ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall directly invokes the privileged installer., Install enables RDP, installs a service, creates an administrator-capable account, and hides folders., Wrapper enables RDP on 3389, disables NLA, permits shadowing without consent, and opens inbound TCP/UDP firewall rules., Account setup enables or creates an account, adds it to Administrators and Remote Desktop Users, then hides it from sign-in., Executable disguise rewrites metadata to impersonate Microsoft/svchost., No source-based exfiltration endpoint was found; the concrete harm is local unauthorized remote-access persistence. - **Evidence against:** No network URLs or HTTP client code found in inspected JavaScript., Payload hashes are verified before installation, but this does not mitigate the malicious install actions. ## Public findings ### 1.
