Foreign states targeting Canadians through social media, CSIS warns

Foreign threat actors and foreign terrorist groups are using the social media feeds of Canadians to profile individuals and magnify misinformation, officials from Canada's spy agency warned members of Parliament Monday.

Cherie Henderson, an assistant director with the Canadian Security Intelligence Service (CSIS), warned that hostile foreign actors aren't waiting for elections to interfere in Canada.

"Foreign interference doesn't just occur during an election," Henderson told members of the House of Commons committee on access to information, privacy and ethics. "Foreign interference occurs all the time, every day."

Henderson said she's also very concerned about the threatof foreign terrorist organizations seeking to drawyoung Canadians to their causes.

"That's what I'm very, very worried about," she said."Because I think that we've got a lot of very vulnerable youth at this time and a lot of very hostile actors that are willing to take advantage of those children."

The committee isstudyingthe extent to which the personal information Canadians share with social media platforms can end up in the hands of foreign governments. The hearings come months after the federal government banned TikTokfrom all government-issued phones onthe recommendation of Canada's chief information officer.

That ban followed warningsthat the Chinese government could access the data ofTikTok users.

Last month, an official from TikToktold the committeethe company follows Canadian law and insisted that China and the Chinese government could not view the data of Canadian users.

On Monday, as officials from Canada's spy agency and the Communications Security Establishment's (CSE) Canadian Centre for Cyber Security appeared before the committee, the focus was on the possible threats posed by all social media platforms.

Henderson said foreign threat actors use a variety of tools and can scrape social media accounts. The more Canadians share online about their lives, the better those actors can target them and influence them.

"Threat actors, including the Russian Federation and the PRC (China), exploit media to spread disinformation, leveraging suggestive algorithms to amplify echo chambers and manipulating content for unsuspecting viewers," Henderson told MPs.

In addition to China and Russia, Iran and North Korea also top the list of countries of concern, she said.

While officials can sometimes observe attempts atinterference taking place, Henderson said identifying the actual origin of that interference can take a very long time.

Sami Khoury, head of the Canadian Centre for Cyber Security, said his agency is worried aboutartificial intelligence beingused by foreign threat actors to increase their ability to interfere in Canada.

"We know that artificial intelligence is often used to amplify misinformation. That is part of the algorithmic nature of some of those tools, to amplify misinformation," Khoury said. "We're also concerned about information leakage with artificial intelligence when you interact online."

Khoury and Henderson said Canadians should pay more attention to the information that they are putting online, where it is being stored and how it can be used.

NDP MP Matthew Green raised the threat posed by social media platforms that aren't based in hostile countries. He pointed out that foreign threat actors can simply buydata on Canadians that companies like Facebook and X (formerly Twitter) gather and sell.

Sharon Polsky, president of the Privacy and Access Council of Canada, warned that informationabout Canadians who use social media platforms is regularly sold and traded and warned that tougher laws are needed to protect personal privacyonline.
