G700 Malware Functionalities and Capabilities

G700 is an advanced RAT with many malicious capabilities. Its functionalities can be divided into several key categories, including data-stealing, financial theft, surveillance, and system damage. Let's take a closer look at these functions:

Data Stealing

• Sensitive Information Capture: G700 can intercept and record SMS messages, including two-factor authentication (2FA) codes, and login credentials for various services.
• Keylogging: The RAT logs keystrokes, capturing everything the victim types, including passwords and other sensitive data.
• Overlay Attacks: By using fake login screens (e.g., phishing attempts), G700 can steal login credentials, credit card information, and other sensitive data when users interact with legitimate-looking apps.

Surveillance

• Camera Control: G700 can activate the device’s front and back cameras to record video without the user’s knowledge.
• Audio Recording: The RAT can also activate the device’s microphone, recording conversations.
• Screen Live-streaming: G700 can even stream the infected device’s screen in real-time to cybercriminals, enabling them to monitor the victim’s actions.

Financial Theft

• Clipper Functionality: G700 has the ability to alter the recipient address in cryptocurrency transactions. During active transactions, it can replace the intended address with that of the attacker’s wallet, facilitating crypto theft.
• Phishing for Banking Information: G700 has been used in overlay attacks targeting e-commerce platforms, email clients, banking apps, and cryptocurrency wallets.

System Damage

• Ransomware Deployment: Although not its primary function, G700 has the potential to deploy ransomware on infected devices.
