Understanding InvisibleFerret

How InvisibleFerret Works

InvisibleFerret begins its malicious activity by collecting system details like the operating system version, hostname, and username. It generates a unique ID for the infected system and categorizes files into five lists to determine what data to steal or ignore.

Key Features

• Data Exfiltration: InvisibleFerret targets sensitive data, including browser credentials, cryptocurrency wallets (e.g., Metamask), authentication apps (e.g., Google Authenticator), and password managers (e.g., 1Password).
• Remote Control: Attackers can execute commands, run additional payloads, and install tools like AnyDesk for further control.
• Stealth Capabilities: The malware monitors clipboard activity, captures keystrokes, and tracks mouse movements without the victim’s knowledge.

Impact on Victims

• Stolen Credentials: Cybercriminals can access personal accounts, steal funds from cryptocurrency wallets, and compromise login credentials.
• Financial Loss: Victims may face monetary theft through compromised banking details or cryptocurrency accounts.
• Additional Infections: The malware can inject more payloads, leading to further damage.
