I thought Gmail was the safest. One of my gmail was hacked and one of my Hotmail too.
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.
How to see if you’re affected
According to a Forbes report, Synthient monitored infostealer malware across the course of nearly a year and provided the data to HIPB.
It reportedly sent a total of 3.5 terabytes of data to HIBP.
Passwords that were also associated with the affected email addresses are also included in the breach, according to the website.
To see if you were affected by the breach, you can enter your email in the search bar of HIBP’s website.
Click on the “Check” button, it will then display the number of breaches affecting your account. If your account has been affected, it will then show a timeline of when the breach occurred and information of what was stolen.
