It lowers RDP protections, creates or enables a privileged RDP account, and hides it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-13T04:31:44.467Z - **Finished:** 2026-08-13T04:32:44.132Z - **Download time:** 762 ms - **Static scan time:** 257 ms - **AI review time:** 58645 ms - **Total time:** 59665 ms ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook elevates and configures a remotely reachable Windows backdoor. It lowers RDP protections, creates or enables a privileged RDP account, and hides it. - **Trigger:** npm postinstall - **Impact:** Remote access and local administrator persistence on the installing Windows host. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json - **Review source:** ai\_review - **Reviewed:** 2026-08-13T04:32:44.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Elevated PowerShell, registry, firewall, and local-account mutation - **Attack narrative:** Installing the package invokes its postinstall installer. After elevation it installs bundled executables, enables and exposes RDP, disables NLA, enables no-consent shadowing, and creates or enables an administrator-class RDP account hidden from the normal sign-in screen. These actions form an unconsented remote-access persistence chain. - **Rationale:** The package performs concrete privileged persistence and weakens remote-access controls automatically during npm installation. This is malicious behavior, not a benign installer primitive. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, %ProgramData%\\BikliWrapper\\admin-credentials.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Postinstall automatically launches the privileged installer., Install enables RDP on port 3389 and opens inbound firewall rules., It disables Network Level Authentication and permits full RDP shadowing without consent., It enables/creates an administrator account, grants RDP access, and hides it from the sign-in screen. - **Evidence against:** Payload hashes are checked before installation., No network or exfiltration API was found in the inspected JavaScript. ## Public findings ### 1.
