Millions of Gmail users who panicked after reports claimed that over 183 million Gmail passwords had been leaked online in a massive data breach breathed a sigh of relief after Google denied the claims.
In a post on social media, Google clarified that there had been no new Gmail security breach.
“Reports of a ‘Gmail security breach impacting millions of users’ are false. Gmail’s defenses are strong, and users remain protected,” the company said in its statement.
“The inaccurate reports stem from a misunderstanding of infostealer databases, which routinely compile various credential theft activity occurring across the web. It’s not reflective of a new attack targeting any one person, tool, or platform,” it added.

Google also advised users to protect themselves from credential theft by enabling two-step verification, adopting passkeys as a safer alternative to passwords, and resetting passwords when they appear in large credential batches.

The false alarm began after several major media outlets reported an alleged “Gmail breach,” claiming that millions of users’ credentials had been exposed — leading many to fear their accounts had been hacked.
The alleged trove, said to contain 3.5 terabytes of data, reportedly surfaced online earlier this month, according to Troy Hunt, the Australian security researcher who runs the breach-notification site Have I Been Pwned.
Hunt had stated that the information appeared to originate from a yearlong sweep of “infostealer” platforms — malware networks that secretly siphoned usernames, passwords, and website addresses from infected devices.
The data was described as a mix of “stealer logs and credential stuffing lists,” Hunt had written in a blog post.
