The tool identifies potential behaviors and functionalities within malware samples such as: - Backdoor capabilities - Service installation mechanisms - Communication methods including HTTP protocols - Various malicious behaviors and techniques Capa supports multiple file formats and analysis methods: - Static analysis of PE and ELF executables - .NET module analysis - Shellcode examination - Dynamic analysis through sandbox report processing The tool provides ATT&CK Tactic and Technique mapping to correlate identified capabilities with the MITRE ATT&CK framework. This mapping helps security analysts understand the potential impact and classification of detected malware behaviors. Capa operates through a command-line interface and can be executed against suspicious files to generate detailed capability reports. The tool has evolved through multiple versions, adding support for different file formats and analysis techniques including dynamic analysis capabilities through integration with the CAPE sandbox.
