Myth Stealer

In June, 2025, security researchers flagged a new Rust-based information stealer dubbed “Myth.” A recent incident revealed how it silently ran in the background of a gamer’s PC—shutting down browsers, siphoning passwords, and even swapping cryptocurrency addresses copied to the clipboard.

Threat Overview

Myth Stealer falls under the “information stealer” category. Written entirely in Rust, it targets both Gecko- and Chromium-based browsers to extract saved passwords, cookies, autofill entries, and credit-card details. Anti-analysis tactics—like string obfuscation and sandbox checks—ensure it remains hidden from traditional inspection tools.

In-Depth Analysis

Infection Vector
Myth commonly arrives via fake game downloads—either through malicious ads on pirated-software forums or in password-protected archives. Once executed, it presents a bogus installer UI, convincing victims that a legitimate game or utility is installing while the stealer unpacks in the background.

Behavioral Profile

1. Sandbox Evasion: Scans for known virtualization markers; exits if detected.
2. Process Termination: Force-closes active browsers (Chrome, Firefox, Edge).
3. Data Harvesting: Extracts credentials, cookies, autofill fields, saved payment cards, and Discord tokens.
4. Clipboard Hijacking: Monitors clipboard for cryptocurrency addresses, replacing them with attacker-controlled wallets.
5. Persistence: Copies itself to %AppData% and creates a Startup shortcut.
6. Data Exfiltration: Compresses harvested data and sends it to a remote server.

Risk Assessment
What happens if files become compromised? Imagine losing all stored logins—and unknowingly redirecting Bitcoin payments. During the 2024 surge in Rust-based malware, Myth stood out for its clipboard hijacking, causing real victims to lose hundreds of dollars in crypto transfers. Overall threat level: High.

Manual Removal of Info-Stealers (For experienced users)

Step 1: Boot into Safe Mode with Networking

Info-stealers often run in the background, making removal difficult. Restarting in Safe Mode with Networking ensures they don’t load at startup.

For Windows 10/11

1. Press Win + R, type msconfig, and hit Enter.
2. In the System Configuration window, go to the Boot tab.
3. Check Safe boot → Network.
4. Click Apply > OK > Restart.

For Windows 7/8

1. Restart your PC and press F8 before Windows loads.
2. Select Safe Mode with Networking and press Enter.

Step 2: Stop Malicious Processes in Task Manager

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Look for unusual processes (high CPU usage, unknown names).
3. Right-click on them and select End Task.

Common Info-Stealer Process Names:

• StealC.exe
• RedLine.exe
• Vidar.exe
• ClipBanker.exe
• Randomized system-like names

Step 4: Delete Malicious Files and Registry Entries

Info-stealers often store files in hidden locations.

Delete Suspicious Files

1. Open File Explorer and navigate to:
   • C:\Users\YourUser\AppData\Local
   • C:\Users\YourUser\AppData\Roaming
   • C:\ProgramData

Step 5: Reset Browsers and Flush DNS

Since info-stealers target browsers, clearing stored credentials is essential.

Reset Browser Data

1. Open Chrome, Edge, or Firefox.
2. Go to Settings → Privacy & Security → Clear Browsing Data.
3. Select Passwords, Cookies, and Cached files → Click Clear Data.

Step 6: Scan for Rootkits

Some info-stealers use rootkit techniques to stay hidden.

1. Download Microsoft Safety Scanner or Malwarebytes Anti-Rootkit.
2. Perform a deep system scan.
3. Remove any detected threats.

Step 7: Change All Passwords & Enable 2FA

Since credentials may have been stolen, update passwords immediately for:
