Gmail accounts among millions of passwords stolen in data breach

Some 183 million email accounts — including millions of Gmail users — are reportedly among a massive data breach.

A website that lets users check if their email accounts have been compromised exposed the data leak affecting addresses and matching passwords, which it said occurred in April 2025.

The website, Have I Been Pwned (HIBP), is a free data leak search engine developed by an Australian white hat hacker.

The website’s creator, Troy Hunt, told the Daily Mail that the leak doesn’t just affect Gmail users but other accounts such as those in Outlook and Yahoo.

“They’re from everywhere you could imagine, but Gmail always features heavily,” Hunt said.

Data from the recent breach was added to HIBP on Oct. 21, with the assistance of threat intelligence service Synthient.
