Canadian cybersecurity researchers are voicing concern and urging people to be vigilant after reports that a staggering 26 billion records have been exposed in a “supermassive leak.”

According to the organizations CyberNews and Security Discovery, data from popular platforms including LinkedIn, X (formerly known as Twitter), Dropbox and Adobe has been exposed in what the research team refers to as the “mother of all breaches.”

“I haven’t seen anything like it,” Canada Research Chair in Security and Privacy Natalia Stakhanova told Global News Wednesday. “It’s a different scale.”
