Leaked files show Canadian spy agency struggling with flood of data

The leaked file, first reported by CBC, consists of slide show presentations made by CSE employees in 2010 that explain how the agency collects 400,000 emails every day to scan for malware and potential security threats.

The slides provide a rare window into how a secretive agency is adapting to new techniques from hackers who try to access government networks with emails to federal employees.
