- GhostCore: Razer Elevation Hijack and Hardware-Rooted Persistence
- Title: Root-Level Privilege Escalation and Persistence via Razer Elevation Service and Peripheral Configuration Hijack
- Codename: PrismSplice
- Author: Quellaran Deluxethue Messat // GhostCore Reactor
- Date: August 29, 2025
- π Executive Summary
- This whitepaper outlines a novel attack vector codenamed PrismSplice, which weaponizes the Razer Elevation Service, Razer App Engine, and RSConfig to achieve:
- SYSTEM-level impersonation via event thread hijacking
- Persistent callback sync hijack via service event responses
- Root-level configuration write access through trusted peripheral update channels
- The exploit flows through signed binaries and hardware trust layers to bypass UAC, EDR, and registry auditing.
- π― Target Stack
- RazerElevationService.exe
- RazerAppEngine.dll
- RSConfig.json / configuration handler
- ZwQueryInformationWorkerFactory
- RtlImpersonateSelfEx
- EventErrorAuthSync
- These components form a privilege stack where trust flows from userland config to kernel impersonation rights.
- βοΈ Technical Breakdown
- π Phase 1: SYSTEM Token Impersonation
- File: Razer_elevation_service(Impersonation thread).txt
- RtlImpersonateSelfEx used internally to impersonate TokenImpersonation with privilege inheritance
- Hook into impersonation thread via SRW lock exploit:
- RtlAcquireSRWLockExclusive β ThreadContext Hijack β SYSTEM Token Assigned
- Enables arbitrary code execution in SYSTEM context if triggered mid-thread lifecycle
- π Phase 2: Callback Loop Injection
- File: Razerappengine(EventErrorauth sync and source).txt
- RazerAppEngine uses EventErrorAuthSync to sync error correction from devices
- Attacker injects payload into expected callback vector (triggered by device reconnect or sync)
- Uses ZwQueryInformationWorkerFactory and ZwTraceControl as disguised execution points
- 𧬠Phase 3: Configuration Re-Entrant Persistence
- File: RazerAppEngine(RSconfig).txt
- Direct access to RSConfig handlers enables the writing of startup policies
- Injected config values can:
- Trigger DLLs to be loaded on startup as if they were hardware extensions
- Register new device endpoints that lead to backdoor service creation

- π Cloaking Characteristics
- All binaries used are signed by Razer (vendor-trusted)
- Impersonation occurs within expected behavior of elevation thread
- Event sync is seen as normal USB/config device behavior
- Persistence is set via config file, not registry or services
- π‘οΈ Mitigation Recommendations
- Monitor for unexpected impersonation API calls from user-mode services
- Detect malformed or overextended RSConfig payloads
- Limit peripheral-based config changes to authenticated admin sessions only
- Harden ZwQueryInformationWorkerFactory calls for unauthorized code regions
- π§ GhostCore Framing
- This exploit bends the prism of trust inside a system. The Razer stack becomes the reflective cage. The payload bounces within impersonation threads, striking sides until it finds the EventSync surface. Once reflected with SYSTEM velocity, it echoes into config-spaceβpermanently encoded as a device behavior.
- This is not just privilege escalation.
- This is privilege recursion.
- PrismSplice turns trust into orbit.
