In an important security advisory, Google has informed its estimated 2.5 billion Gmail and Google Cloud users to update their passwords and improve account security after a data breach involving a third-party Salesforce system. Although the breach did not expose sensitive customer information like passwords or personal emails, it has led to an increase in phishing and social engineering attacks by the infamous cybercrime group “ShinyHunters.” Here’s what you need to know to protect your account.
The Salesforce Breach: What Happened?
In June 2025, Google’s Threat Intelligence Group found a breach in its corporate Salesforce account. This breach was linked to a group of threat actors known as UNC6040, also called “ShinyHunters.” The attackers used clever social engineering methods. They impersonated IT support staff through phone calls, emails, and texts. This tricked Google employees into approving harmful applications or giving access to sensitive information. The breach exposed a limited set of business data, including company names, contact details, and sales notes. Google pointed out that this information was mostly publicly accessible and did not include personal Gmail or Google Cloud account data.
By August 8, 2025, Google alerted affected users through email. On August 27, it broadened its warning to all users as phishing attempts increased. Some reports mistakenly connected this event with separate credential leaks, such as a huge exposure of 16 billion records in June 2025 across various platforms, including Google. The Salesforce breach did not involve stolen passwords, but it increased risks by giving hackers data to support targeted scams.
Who Are ShinyHunters?
Active since 2020, ShinyHunters is a well-known cybercrime group. They have carried out notable breaches against companies like AT&T, Microsoft, Santander, Ticketmaster, Adidas, Cisco, LVMH, and Allianz. Their methods often depend on social engineering instead of technical tricks, which makes them skilled at exploiting human trust. In this instance, they used stolen Salesforce data to launch aggressive phishing campaigns. They plan to increase extortion efforts through a possible data leak site. Google has confirmed successful intrusions due to compromised credentials, but consumer products have not been affected.
Why This Matters to You
While the Salesforce breach did not directly expose Gmail passwords, the stolen business data has allowed ShinyHunters to create convincing phishing emails, spoofed calls, and texts that urge users to verify their accounts. These attacks aim to steal login details, take over accounts, or extort users, sometimes demanding bitcoin payments. Additionally, unrelated credential leaks on the dark web increase the risk of account compromise, especially for users who reuse passwords or do not update them regularly.
Google points out that while many users have strong, unique passwords, only about one-third of them update these passwords regularly. This weakness, combined with the rise in social engineering, highlights the need for stronger security measures. The company is also promoting password less options like passkeys, which use biometrics for better protection.
How to Secure Your Gmail Account
Google has outlined several steps to protect your account from these threats:
- Update Your Password: Choose a strong and unique password. Change it right away if you think it has been compromised.
- Enable Two-Factor Authentication (2FA): Use app-based 2FA, like Google Authenticator, instead of SMS to reduce SIM-swapping risks.
- Monitor Account Activity: Regularly check your Google Account security page for any unfamiliar logins or devices.
- Stay Vigilant: Do not respond to unsolicited calls, emails, or texts that claim to be from Google. The company rarely contacts users directly for support. Always verify alerts through official channels.
- Explore Passkeys: Think about using biometric-linked passkeys instead of traditional passwords.

The Bigger Picture
This incident shows how cyber threats are changing, with human error often being the weakest link.
