How EagerBee Malware Works

Initial Infection

EagerBee malware infiltrates systems through various attack vectors, including phishing emails, drive-by downloads, and compromised software downloads.

DLL Hijacking & Payload Injection

Once inside, it abuses DLL hijacking techniques to disguise its presence within legitimate Windows processes. Upon execution, the backdoor payload is loaded directly into system memory, preventing easy detection.

Data Collection & System Profiling

EagerBee systematically gathers information about the infected device, including:

• Operating system version
• Memory usage and system performance
• Time zone and regional settings
• Installed software and recent updates
• Network configuration and IP addresses

Remote Access & Execution

After establishing a connection with its Command and Control (C&C) server, EagerBee downloads and executes additional malware components, giving hackers full control over the compromised system.
