Recent claims that Google issued a sweeping security warning to billions of Gmail users have been firmly denied by the company, which clarified that no such alert was sent and that Gmail's existing protections remain effective.
The clarification comes after widespread coverage by news outlets, including The Independent, which cited Google's Threat Intelligence reports to claim that all Gmail users had been warned of an active password breach involving the hacker group ShinyHunters. Google's official statement, however, categorically dismissed these claims, calling them “entirely false” and stressing that its phishing and malware protections continue to block over 99.9% of attempted attacks.
Gmail is one of the world's most widely used email services, integrated deeply with Google's cloud offerings and productivity suite. The platform serves over 2.5 billion users globally and is a frequent target of phishing campaigns due to its massive user base. Google has invested heavily in AI-driven threat detection and automated abuse mitigation systems that work behind the scenes to secure user accounts.
Google Threat Intelligence Group (GTIG), Google's dedicated threat intelligence arm, routinely publishes deep-dive reports into emerging threats across Google's infrastructure and the broader internet. Its work often informs both internal mitigations and public awareness efforts.
The confusion appears to stem from a misinterpretation of a legitimate security advisory published by GTIG on June 5, 2025, and updated in August. That report detailed a targeted phishing and extortion campaign by threat actor UNC6040, which exploited Salesforce-connected applications using voice phishing tactics. The attackers impersonated IT support staff to trick corporate users into installing a malicious version of Salesforce's Data Loader tool, leading to unauthorized data access.
In a follow-up posted August 8, Google confirmed that it had completed direct notifications to a limited set of users affected by a breach involving one of Google's corporate Salesforce instances. These individuals were primarily small and medium business contacts stored in Salesforce and not Gmail account holders at large. The affected data was limited to publicly available business information, such as names and contact details, not sensitive Gmail credentials.
The false reports mischaracterized this targeted notification effort as a global warning affecting Gmail's entire 2.5 billion user base. Google's rebuttal emphasized that while phishing threats are ongoing, no new large-scale breach of Gmail occurred, and users are not at increased risk from this incident.
