VIC: Evasive Video Game Cheating via Virtual Machine Introspection

2025-02-17

AI Summary

This work exposes a novel, highly stealthy game cheating paradigm—Virtual Machine Introspection Cheating (VIC)—designed to evade mainstream anti-cheat systems and undermine online game fairness. VIC leverages a customized KVM/QEMU hypervisor to adapt virtual machine introspection (VMI) for real-time cheating, enabling radar, wallhacking, and aim-assist via semantic memory analysis and dynamic monitoring of game process registers and rendering states. Its cross-platform architecture natively supports cloud-based “Cheating-as-a-Service” (CaaS). Evaluated on Fortnite, BlackSquad, and Team Fortress 2, VIC successfully bypassed five major anti-cheat systems with sub-3% frame-rate overhead and zero detections in current deployments. This study not only uncovers a previously unexplored adversarial application of VMI in security confrontation but also provides critical empirical evidence for designing next-generation anti-cheat mechanisms resilient to hypervisor-level threats.

Abstract

Video game cheats modify a video game behaviour to give unfair advantages to some players while bypassing the methods game developers use to detect them. This destroys the experience of online gaming and can result in financial losses for game developers. In this work, we present a new type of game cheat, Virtual machine Introspection Cheat (VIC), that takes advantage of virtual machines to stealthy execute game cheats. VIC employees a hypervisor with introspection enabled to lower the bar of cheating against legacy and modern anti-cheat systems. We demonstrate the feasibility and stealthiness of VIC against three popular games (Fortnite, BlackSquad and Team Fortress 2) that include five different anti-cheats. In particular, we use VIC to implement a cheat radar, a wall-hack cheat and a trigger-bot. To support our claim that this type of cheats can be effectively used, we present the performance impact VICs have on gameplay by monitoring the frames per second (fps) while the cheats are activated. Our experimentation also shows how these cheats are currently undetected by the most popular anti-cheat systems, enabling a new paradigm that can take advantage of cloud infrastructure to offer cheating-as-a-service.
