In the ever-evolving landscape of cybersecurity, Remote Access Trojans (RATs) continue to pose a significant threat to individuals and organizations. One such malware, WH-RAT v1.0WH-RAT v1.0.1, has gained attention for its stealthy infiltration and malicious capabilities. This presentation/article examines WH-RAT, its key features, its operation, and strategies for protection against it.
WH-RAT v1.0.1 | free for windowsWhat is WH-RAT?
WH-RAT (Windows Hidden Remote Access Trojan) is a type of malicious software designed to provide attackers with unauthorized remote control over an infected system. Like other RATs, WH-RAT operates covertly, allowing cybercriminals to steal sensitive data, execute commands, and maintain persistence on compromised devices.

Key Features of WH-RAT v1.0 WH-RAT v1.0.1
WH-RAT incorporates several advanced functionalities that make it a potent threat:

1. Stealth & Evasion Techniques
Process Injection: Hides within legitimate processes (e.g., explorer.exe).
Anti-Detection Mechanisms: Bypasses antivirus and sandbox analysis.
Rootkit Capabilities: Conceals its presence in the system.
2. Remote Access & Control
Command Execution: Attackers can run arbitrary commands.
File Manipulation: Upload, download, or delete files remotely.
Persistence Mechanisms: Ensures it remains installed after reboots.
3. Surveillance & Espionage
Keylogging: Captures keystrokes to steal passwords.
Screen Capture: Takes screenshots of user activity.
Audio/Video Recording: Activates microphone and webcam.
4. Data Exfiltration
Clipboard Monitoring: Steals copied text (e.g., crypto wallet addresses).
Browser Data Harvesting: Extracts saved passwords, cookies, and history.
Network Sniffing: Intercepts unencrypted network traffic.
5. Propagation & Botnet Functionality
Self-Replication: Spreads via infected USB drives or network shares.
Exploits Vulnerabilities: Leverages unpatched software flaws.
DDoS Capabilities: Can be used in coordinated attacks.

Agent Tesla is a sophisticated malware-as-a-service (MaaS) Remote Access Trojan (RAT) and keylogger cybercriminals use to steal sensitive data. The Agent Tesla Builder 3.2.5.5 is a tool that allows attackers to customize and generate malicious payloads for distribution.

Supports multiple infection methods (e.g., document macros, fake installers).
2. Persistence Mechanisms
Adds itself to Windows Startup (Registry, Task Scheduler).
Uses process hollowing (injects into legitimate processes like explorer.exe).
3. Data Theft Capabilities
Keylogging
Clipboard theft
Form grabbing
Screen capture
4. Communication & Exfiltration
SMTP, FTP, Telegram, or HTTP for data exfiltration.
Encrypted C2 (Command & Control) communication.
5. Anti-Analysis & Evasion
Code obfuscation
VM/Sandbox detection
Delayed execution
