How SHUYAL Works

Infection & Reconnaissance

SHUYAL typically infiltrates systems via phishing emails, cracked software, or malicious installers. Once executed, it collects system metadata including disk information, keyboard and mouse configurations, screen resolution, and desktop wallpaper. These details are gathered silently using background system queries.

Stealth & Persistence

The malware disables the Windows Task Manager to avoid manual detection and prevents its window from being seen. It ensures persistence by copying itself to the Startup folder. Once data exfiltration is complete, it deletes itself and any associated batch files to erase traces of its presence.

Data Theft & Exfiltration

SHUYAL targets login credentials from 19 popular browsers such as Chrome, Edge, Opera, Brave, Tor, and others. It steals files like “Login Data,” decrypts stored credentials using the Windows Data Protection API (DPAPI), and collects clipboard content and screenshots. Discord tokens are also harvested. All stolen data is compressed into an archive and sent via a Telegram bot, ensuring secure and fast exfiltration. Temporary files are deleted afterward to cover its tracks.

Detailed Analysis

How I Got Infected

Infections usually occur through phishing emails containing malicious attachments, bundled software installers, or fake/cracked tools. Once launched, SHUYAL begins data harvesting immediately without raising any obvious alerts.

What Does It Do

SHUYAL extracts saved credentials from browsers, captures clipboard data, screenshots, Discord tokens, and gathers hardware and software metadata. It disables user tools like Task Manager, maintains persistence, and exfiltrates all stolen content to a remote Telegram-controlled bot.

Should You Be Worried For Your System

Yes. SHUYAL is a high-risk threat due to its stealth capabilities, wide browser targeting, and data exfiltration via encrypted Telegram communications. Victims may not notice any infection until sensitive data is misused. Immediate action is necessary to prevent identity theft, unauthorized access, and further data compromise.

   • C:\Users\YourUser\AppData\Local
   • C:\Users\YourUser\AppData\Roaming
   • C:\ProgramData

Step 6: Scan for Rootkits

Even after manual removal, some info-stealers may hide as rootkits.

1. Download Malwarebytes Anti-Rootkit or Microsoft Safety Scanner.
2. Run a deep scan and remove any detected threats.

Step 7: Change All Passwords & Enable MFA

Since info-stealers extract credentials, immediately update passwords for:

• Email accounts
• Banking and finance sites
• Social media
• Cryptocurrency wallets
• Business and work logins

Enable two-factor authentication (2FA) to prevent unauthorized access.
