Foreign states turning to ‘big data’ to aid influence campaigns: intelligence official

Foreign state and non-state actors are increasingly hoovering up “big data” on Canadians to better focus their foreign influence campaigns, a senior intelligence official said Thursday.

Alia Tayyeb, the deputy chief of the Communications Security Establishment (CSE), told the foreign interference inquiry that hostile intelligence agencies are gathering large amounts of data about Canadians’ personal lives to “help influence campaigns.”

“One of the newer developments in the threat landscape is the prevalence of personal information online about individuals. And so … one thing we’re seeing increasingly is the corollary of that is big data collection,” Tayyeb told the Hogue inquiry.

“So where state actors, and non-state actors quite frankly, collect personal information, commercial information, with an attempt to use that information for a variety of purposes which range from traditional espionage (or) in the context of this commission, for foreign interference activities as well.”

Tayyeb is the deputy chief at CSE responsible for signals intelligence — basically, collecting foreign intelligence from the internet — so she would be familiar with the value of collecting large amounts of data for intelligence purposes. The CSE is not permitted to spy on Canadians or anyone in Canada, except in cases where they’re assisting domestic law enforcement or security agencies.

But she said the CSE also sees actors like the People’s Republic of China (PRC) continuing to use traditional forms of espionage, such as the “use of proxies, use of proxy organizations, (and the) use of state-run media” to further their interests, in addition to the cyber threats that CSE attempts to counter.

The CSE was one of the central security organizations —
