  • Malware Analysis Tool and Visualization System (Development)

    I worked on a team of 4 developers building a prototypical system where individuals could submit malware to be automatically analyzed and visualized. The visualizations allowed individuals to explore the "social network" of a malware sample, by seeing other ingested samples with similar properties, as well as providing an at-a-glance view of the malware's capabilities.

    Due to the small team size, all members included myself worked on a variety of different areas of the system. Some of my larger roles included building new visualizations using D3 and Sigma JS, developing an interface for uploading and ingesting new samples, and implementing crucial back-end functionality for handling communication between system components. Technologies and languages used in my work include Tornado web server, ZeroMQ, MongoDB, Elasticsearch, Python, AngularJS, JavaScript, and LESS.
