What is DT Stealer V1.3?
What is DT Stealer V1.3?DT Stealer V1.3 is a type of information-stealing malware (info stealer) that extracts valuable data from compromised devices. It is typically distributed through phishing emails, malicious downloads, or exploit kits. Once installed, it operates stealthily to collect credentials, financial data, browser histories, and other sensitive information, which is then exfiltrated to a remote server controlled by cybercriminals.
Key Features of DT Stealer V1.3
1. Credential Theft
- Extracts saved passwords from browsers (Chrome, Firefox, Edge, Opera, Brave).
- Target password managers like KeePass and LastPass if credentials are cached.
2. Cookie & Session Hijacking
- Steals browser cookies to bypass two-factor authentication (2FA) and hijack active sessions (e.g., social media, banking sites).
3. Cryptocurrency Wallet Theft
- Scans for and extracts private keys from:
- MetaMask
- Exodus
- Electrum
- Binance Chain Wallet
4. File Grabbing (FileGrabber Functionality)
- Searches for and exfiltrates documents (PDFs, Word, Excel), databases, and sensitive files from:
- Desktop
- Downloads folder
- Cloud storage sync folders (Dropbox, Google Drive)
5. Keylogging & Screen Capture
- Logs keystrokes to capture typed passwords and messages.
- Takes screenshots periodically to monitor user activity.
6. Anti-Detection & Persistence Mechanisms
- Process Injection – Hides within legitimate processes (e.g., explorer.exe).
- Persistence – Modifies registry keys or schedules tasks to survive reboots.
- Evades AV Detection – Uses obfuscation, packing, and runtime decryption.
7. Telegram & Discord Integration
- Some variants send stolen data directly to Telegram bots or Discord webhooks for real-time exfiltration.
8. Customizable Builds
- Attackers can configure the malware to target specific data types or avoid certain security checks.
