Abstract: An embodiment of the present invention is directed to an extraction and analysis system that comprises a network sensor configured to capture network traffic, a source document processor configured to extract text from source documents in the captured network traffic, an artificial intelligence (AI) inference engine configured to extract structured banking information from the extracted text, and an interface to a security information and event management (SIEM) system configured to receive the extracted structured banking information and generate alerts based on the extracted structured banking information. The system enables automated extraction and analysis of banking details from various document types within network traffic for enhanced security monitoring and threat detection.
