Canadian vaccine passport app may have exposed hundreds of thousands of users’ personal data

A vaccine passport app that has more than 650,000 registered users, according to its CEO, may have exposed hundreds of thousands of users’ personal data.

Private proof-of-vaccination app Portpass exposed personal information, including the driver’s licences, of what could be as many as hundreds of thousands of users by leaving its website unsecured.

On Monday evening, CBC News received a tip that the user profiles on the app’s website could be accessed by members of the public.

CBC are not sharing how to access those profiles, in order to protect users’ personal information, but has verified that email addresses, names, blood types, phone numbers, birthdays, as well as photos of identification like driver’s licences and passports can easily be viewed by reviewing dozens of users’ profiles.

The information was not encrypted and could be viewed in plain text.

This was despite, the Canadian Calgary-based company CEO Zakir Hussein dening the app had verification or security issues and accused those who raised concerns about it of breaking the law.

The Canadian Broadcasting Corporation called Hussein late Monday, and agreed to hold off on publishing an article on the lapse until late Tuesday morning in order to give his team time to lock down the site and protect user information.

The portpassportal.com web app was pulled offline that evening and users of the mobile app were met with “Network error” pop-up messages if they attempted to upload or modify any information.

Hussein said Tuesday morning that the breach only lasted for minutes, and repeated that claim when CBC pointed out it had reviewed the personal information for more than an hour — and it’s unknown how long the information was exposed before that tip was received.

“Someone that’s out there is trying to destroy us here, and we’re trying to build something good for people,” he said.

“There’s holes, and what I’m realizing is I think there are some things that we need to fix here. And you know, we’re trying to play catch-up, I guess, and trying to figure out where these holes are.”

Hussein has said Portpass has more than 650,000 registered users across Canada.

Cybersecurity analyst Ritesh Kotak said he was shocked but not surprised to hear users’ information was exposed.

“These were exactly the privacy and security concerns I’ve previously raised when it comes to using third-party apps,” Kotak said. “You’ve gotta ask yourself, ‘Where’s the data housed? Who has access to it? Is it encrypted?’… If this gets out to the wrong individuals it opens them up to fraud, identity theft and a whole other world of potential issues.”
