In early 2012, Communications Security Establishment Canada analyzed telecommunications flows surrounding Brazil's Ministry of Mines and Energy. The ministry was described by CSEC as "a new target to develop."
Codenamed "Olympia," the suite of analytic tools used by CSEC to parse the ministry's telephone and Internet use was the subject of a presentation made to allied intelligence analysts inside the United States.
The presentation does not explain the purpose of the CSEC surveillance.
The Globe and Mail is making available a copy of a leaked presentation, in collaboration with Brazil-based American journalist Glenn Greenwald. The document was first acquired by Edward Snowden, a former U.S. National Security Agency contractor.
Some material in the presentation, including phone numbers, Internet Protocol addresses and individual names have been redacted by The Globe to protect privacy.
This slide show was first reported by Brazil's Fantastico TV program in October.
CSEC is a Canadian electronic-eavesdropping agency that has a $460-million annual budget, with 2,100 employees working to provide "foreign intelligence" to government officials.
The Globe contacted CSEC several times asking the agency to explain the content of the slides and the purpose of the surveillance. The agency declined to do so.
