What is the BRATA RAT 2025
This banking trojan operates as a multi-stage threat designed specifically for financial fraud and data theft. The software is typically distributed through:
- SMS phishing (smishing) campaigns impersonating banks.
- Fake banking applications in third-party app stores.
- Compromised websites posing as financial services.
- Malicious email attachments targeting finance departments.
Once installed, it enables attackers to:
- Capture online banking credentials through overlay attacks.
- Bypass multi-factor authentication (MFA) mechanisms.
- Initiate fraudulent transactions through remote control.
- Monitor victim activity through screen recording.
- Collect sensitive financial documents.
Key Features

| Session Hijacking | Steals authentication cookies and tokens |
| Remote Control | Provides attackers with real-time device access |
| MFA Bypass | Intercepts SMS codes and authentication prompts |
| Screen Recording | Captures user activity for later analysis |
| File Exfiltration | Steals financial documents and sensitive files |
| Self-Destruct | Removes traces of infection after completing objectives |
How BRATA RAT 2025 works
1. Delivery and Initial Infection
The malware employs multiple distribution vectors:
- Social engineering tactics to trick users into installing malicious APKs.
- Exploitation of accessibility services to gain persistent permissions.
- Dropper applications that download the full payload post-installation.
Upon execution, it:
- Requests extensive permissions (accessibility, SMS, overlay).
- Disables Google Play Protect and other security features.
- Establishes communication with C2 servers.
- Downloads configuration files for targeted banks.
2. Banking Fraud Techniques
The Trojan implements sophisticated financial theft methods:
Overlay Attacks:
- Detects when specific banking apps are opened.
- Displays identical-looking fake login screens.
- Captures entered credentials in real-time.
Session Hijacking:
- Steals authentication cookies and tokens.
- Replays sessions to bypass login procedures.
- Maintains active sessions for fraudulent transactions.
MFA Bypass:
- Intercepts SMS verification codes.
- Captures push notification approvals.
- Uses accessibility services to auto-confirm transactions.
3. Data Exfiltration and C2 Communication
Stolen data is transmitted via:
- Encrypted HTTPS connections to C2 servers.
- Telegram bots for real-time data access.
- Temporary cloud storage for large document transfers.
The malware uses:
- Domain generation algorithms (DGA) for resilient C2.
- Fast-flux DNS to evade takedowns.
- Encrypted configuration files.
4. Persistence and Evasion
Advanced techniques include:
- Multiple persistence mechanisms (foreground services, broadcast receivers).
- Code obfuscation and anti-debugging measures.
- Sandbox detection to prevent analysis.
- Dynamic payload loading to reduce the initial footprint.
- Self-destruct sequence when detected
