Description

This document is a CSEC presentation deck giving an overview of LEVITATION, "a behaviour-based target discovery project." LEVITATION is used to identify targets based on documents downloaded from free file upload (FFU) services such as Sendspace and Rapidshare. A special source, codenamed ATOMIC BANJO, collects HTTP metadata for FFU sites, which is then filtered for documents of interest. Metadata from the documents of interest is correlated to personally-identifying information, if available, from CSEC databases MUTANT BROTH and MARINA, with the aim of locating the person who downloaded the document. The presentation concludes with two successful case studies. <br><br> Christopher Parsons has written a more detailed analysis of the LEVITATION presentation, accessible <a href="https://www.christopher-parsons.com/writings/cse-summaries/#levitation-and" target="_blank">here.</a>
