Malicious Installers Target AI Enthusiasts
A new malware campaign is deceiving content creators, gamers, and AI enthusiasts by offering fake installers for popular software tools such as ChatGPT and Claude. These counterfeit files, hosted on well known platforms like GitHub and SourceForge, deliver a powerful backdoor named DinDoor. The attackers have also compromised YouTube channels, using AI generated videos to drive traffic to the malicious repositories. Some of these videos have already garnered over 50,000 views, indicating a significant reach and potential for widespread infection.
Security researchers at Malwarebytes identified the campaign after discovering suspicious installers and plugins impersonating not only ChatGPT and Claude but also Ableton Live, AutoTune, and Kontakt. By leveraging the inherent trust users place in GitHub and SourceForge, the attackers make their fake projects appear legitimate, luring victims into downloading the harmful payload.
Infection Chain and Capabilities
Once a user visits a compromised repository and executes a copied command in their terminal, thinking they are installing genuine software, the infection begins. The command silently downloads an MSI installer file and runs it through Windows’ built in installer tool. This MSI file then deploys a CMD file and a PowerShell script onto the victim’s system. The PowerShell script proceeds to install the Deno JavaScript runtime using standard Windows package managers like Scoop and WinGet, furthering the attack.
After installation, DinDoor establishes a connection to a command and control server, enabling the delivery of a full featured remote access Trojan. This RAT can steal data from browsers and cryptocurrency wallets, capture screenshots, record clipboard activity, and even spy on victims through a hidden video stream that uses the Microsoft Edge browser as cover. The backdoor’s capability to remain undetected while exfiltrating sensitive information makes it a serious threat to both individual users and organizations.
