Google Data Breach: 2.5 Billion Gmail Users at Risk of phishing Attacks
Google has confirmed a significant data breach affecting approximately 2.5 billion Gmail users worldwide.The breach, perpetrated by the notorious hacking group SHINee Hunters (tracked as UNC6040 by GoogleS Threat Intelligence Group), compromised data within Google’s Sales Customer Relationship Management (CRM) system. This incident elevates the risk of targeted phishing attacks against a vast number of individuals and businesses.
Details of the Breach
Google announced on August 6th that SHINee Hunters gained unauthorized access to the CRM system in June. While the compromised data primarily consists of basic business information – company names and contact details – Google assures users that passwords and sensitive personal information were not directly exposed.However, the leaked contact information significantly increases the potential for sophisticated phishing campaigns.
This attack is part of a broader campaign targeting major global corporations, including Adidas, Cisco, Qantas Airlines, Pandora, Allianz Life, and luxury brands Louis Vuitton, Dior, and Tiffany & Co. The group has already reportedly received a ransom payment of approximately 400 million Korean Won (roughly $300,000 USD) from one company.
Sophisticated Phishing Tactics Employed
SHINee Hunters utilized a highly sophisticated voice phishing (vishing) technique to infiltrate the system. Attackers impersonated IT support personnel, contacting employees and convincing them to install malicious versions of the Salesforce Data Loader submission. By tricking victims into entering a “connection code,” the attackers gained legitimate access to the Salesforce environment and extracted large volumes of customer data.

Reports of related phishing attempts are already surfacing online, with users on platforms like Reddit describing receiving phone calls from individuals falsely claiming to be Google employees investigating account security issues.
Ransomware and Data Leak Threats
SHINee Hunters is known for its extortion tactics. The group threatens companies with data release unless a ransom is paid and has indicated plans to sell the stolen data on hacking forums if negotiations fail. Google has warned that the attackers are likely to establish a data leak site (DLS) to further pressure victims.
SHINee Hunters has been active as 2020 and previously compromised over 165 organizations, including AT&T, Santander Bank, and Ticketmaster in 2023. Their persistent activity and evolving tactics pose a continuing threat to businesses and individuals.
Google’s Security Recommendations
Google is urging users to take immediate steps to enhance their security. These recommendations include:
- Utilizing Google’s Security Checkup tools to identify account vulnerabilities.
- Enrolling in Advanced Protection Program to block harmful files.
- Restricting Gmail access for unauthorized third-party apps.
- Transitioning to Passkeys as a more secure choice to passwords.
Pro Tip: Regularly review your account activity and be wary of any unsolicited requests for personal information, especially those received via phone or email.
Google emphatically states, “There is never a request for employees to reset or change their account by phone or e-mail.” This underscores the importance of verifying any such requests through official channels.
The Evolving Landscape of Cyber Security
Cybersecurity experts emphasize that this incident highlights the growing danger of social engineering attacks, which exploit human vulnerabilities rather than technical weaknesses. As outlined in the National Institute of Standards and Technology (NIST) guidelines, a layered security approach is crucial, combining technical controls with robust employee training and awareness programs.

GDN ViewPoints: A Paradigm Shift in Cyber Security
The Google hacking case underscores a basic challenge in modern cybersecurity. Even organizations with world-class security technology are vulnerable to sophisticated social engineering attacks. The fact that Google’s own threat intelligence team was targeted using similar tactics is particularly concerning.
This incident mirrors the Snowflake attack in 2024, where attackers bypassed technical defenses by exploiting human psychological weaknesses. The focus is shifting from “technology versus technology” to “psychology versus security consciousness.”
The increasing sophistication of AI-powered voice cloning technology further exacerbates the threat. Deepfake voice technology could convincingly mimic the voices of CEOs or IT managers, making it even more difficult for employees to identify fraudulent requests. What steps can your institution take to prepare for this evolving threat landscape?
Companies must prioritize building “human firewalls” alongside technical defenses. Regular security training, simulated social engineering attacks, and a culture of skepticism are essential. Verification procedures should be mandatory for all urgent or important requests, irrespective of the source.
Ultimately, human judgment and security awareness may be the most critical defenses in an era where technology provides new weapons to both attackers and defenders.
The threat of phishing attacks is a constant and evolving challenge. As attackers become more sophisticated,organizations and individuals must remain vigilant and proactive in their security measures. The rise of AI-powered tools is expected to further complicate the landscape, requiring continuous adaptation and investment in security awareness training. Staying informed about the latest threats and best practices is crucial for mitigating risk.
