Description

Malicious C# application for Windows, obfuscated using .NET Reactor.

Operating routine

When launched, the trojan decrypts the resources it contains and launches a stealer capable of extracting accounts and data from the following applications: FoxMail, MailBird, MailMaster, MS Outlook, Filezilla, WinSCP, Steam, Discord, Pidgin, Signal, Telegram, OpenVPN, ProtonVPN, Internet Download Manager, Ngrok, OBS Studio, Opera, Firefox- and Chromium-based browsers and their extensions.

The stealer also compromises the Windows activation key.

It sends the following information to the threat actor: computer name, user name, Windows version, installed antivirus software, CPU and GPU names, RAM size, monitor model, LAN and network interface information, and cryptocurrency wallets. Additionally it takes a screenshot.

System information is sent to 95.216.99[.]206. The stealer can also exfiltrate it over the TOR network.
