Security researchers and sandbox telemetry identified malware campaigns abusing GitHub-hosted gaming cheat projects to distribute remote access trojans, including AsyncRAT and VileRAT. One analyzed sample was delivered from a GitHub raw URL and disguised as an Escape from Tarkov cheat-related .scr file, using a gaming-themed lure to entice users seeking cheats, DLL injectors, or other unauthorized tools. ANY.RUN classified the sample as malicious and linked it to AsyncRAT, a trojan that can provide remote control, keystroke capture, webcam access, and data theft from infected Windows systems.
Additional reporting warned that attackers were packaging malware inside purported open-source game cheat repositories and injector utilities on GitHub, broadening the campaign beyond a single title or payload. Technical analysis tied related activity to VileRAT, indicating that threat actors are using trusted developer platforms and cheat-seeking communities as an infection channel for commodity and custom RAT malware. Reported indicators for the AsyncRAT sample included SHA1 3065DA0D35988807C34C98164D35385F846AB1DF and SHA256 84C8AD42D82A82951A1968C738FC813A83FC5CD6F1C2F446F2960CF21A373E14.

Threat actors abused GitHub to distribute malware by cloning legitimate repositories, impersonating trusted open-source projects, and poisoning search results to steer victims to trojanized downloads. One campaign spoofed the **AIMMY** game-cheat project through a cloned repository and the lookalike site `aimmy.app`, while also exploiting GitHub's issue-draft upload behavior to host malicious files on the original benign repository via direct links that appeared trustworthy. The delivered packages included files such as `Aimmy.bat`, `AimmyLauncher.exe`, `lua51.dll`, and supporting data, with the malware implemented through obfuscated **LuaJIT** code. Follow-on analysis tied similar GitHub repo poisoning activity to **SmartLoader**, which used trojanized `lua51.dll` components and heavily obfuscated Lua payloads to deploy **StealC** infostealer. The malware performed anti-debugging and anti-tamper checks, captured screenshots, verified connectivity and geolocation, and fetched additional payloads from attacker-controlled GitHub repositories. Researchers found it also used the **EtherHiding** technique, querying the Polygon PoS blockchain for dynamically updated command-and-control data, before exfiltrating browser credentials, cookies, cryptocurrency wallet information, and email data to attacker infrastructure including `213.176.72[.]200`.

Researchers reported a large-scale GitHub malware distribution campaign that has operated since March 2025, using repositories masquerading as cracked browser extensions, gaming cheats, developer tools, and, more recently, fake AI skills and MCP servers. The activity has been tied to a Vietnamese-speaking operator and spans more than 47 GitHub accounts and 600 malicious ZIP archives, with some accounts believed to have been compromised rather than created solely for abuse. The campaign’s social-engineering lures target both general users and developers seeking unofficial software, automation tools, or AI-related components. The repositories deliver a multi-stage **LuaJIT** loader chain that ultimately installs the **StealC** information stealer. Payloads are fetched from GitHub “dead drop” repositories, then decrypted through layered obfuscation including hex, XOR, `base64url`, and **AES-ECB** before process hollowing is used for injection. Researchers said the malware also resolves command-and-control infrastructure through **Polygon Mainnet** smart contracts, allowing operators to rotate C2 URLs or IPs without changing deployed binaries; telemetry linked the activity to detections such as BitDefender `Gen:Heur.FakeGit.1` and ESET’s `Lua/Agent` family, while infrastructure usage heavily overlapped with bulletproof hosting providers including **ASN 207957 (Serv.host Group Ltd)**.

Microsoft Threat Intelligence reported an active malware campaign targeting gamers by distributing **trojanized gaming utilities** through browsers and chat platforms, leading victims to execute a multi-stage downloader that ultimately installs a **Java-based remote access trojan (RAT)**. The infection chain was observed staging a portable Java runtime and launching a malicious JAR (`jd-gui.jar`), while using **PowerShell** and living-off-the-land binaries such as `cmstp.exe` to reduce detection. The activity includes defense evasion by deleting the initial downloader and adding **Microsoft Defender exclusions**, and persistence via a scheduled task and a startup script named `world.vbs`; the RAT then beacons to **`79.110.49[.]15`** for C2, enabling data theft and follow-on payload delivery. Reporting also noted the campaign’s use of gaming-adjacent filenames to increase execution likelihood (e.g., `Xeno.exe`, `RobloxPlayerBeta.exe`) and emphasized that the final payload functions as a **loader/runner/downloader/RAT** rather than a single-purpose stealer, increasing the risk of secondary malware deployment. Separately, one report highlighted the emergence of *Steaelite*, a Windows RAT advertised on criminal forums with claimed “FUD” capabilities and an integrated panel combining data theft and ransomware features, underscoring broader commoditization of multi-function RAT ecosystems even when not directly tied to the specific trojanized-gaming-tools intrusion chain.
