Unauthorized Access to Google's Systems: A Look at Potentially Compromised User Data
Google Suffers Data Breach at the Hands of ShinyHunters
In a shocking turn of events, tech giant Google has confirmed a data breach on one of its databases, specifically a Salesforce instance, in June 2025. The compromised data primarily consists of business contact information, including company names, phone numbers, and internal notes related to small and medium-sized businesses from Google's customer relationship management system [1][2][3].
The breach is believed to be associated with the ShinyHunters ransomware group, also known as UNC6040. This cybercriminal organization is notorious for extortion attempts, using emails or telephone calls demanding bitcoin ransom payments within 72 hours of compromise [6].
The attackers employed a social engineering technique called voice phishing (vishing) to impersonate IT personnel and deceive English-speaking Google employees who worked with Salesforce clients. They convinced these employees to connect and authorize a maliciously modified version of Salesforce’s Data Loader tool, enabling the attackers to exfiltrate customer data shortly before Google revoked their access [1][2][5].
Google has warned that this threat actor might use the stolen data to escalate pressures on victims by launching public data leak sites [1].
To mitigate such risks, it is recommended for organizations to:
- Conduct thorough employee training to recognize social engineering and vishing attempts, emphasizing verification procedures before authorizing software or access requests.
- Implement strict controls and monitoring on third-party applications integrated with SaaS platforms like Salesforce, especially limiting permissions and promptly reviewing authorization requests.
- Increase vigilance for suspicious activities around app authorizations and data exports within CRM systems.
- Review and strengthen access protocols for sensitive SaaS services, including enforcing multi-factor authentication and least privilege access.
- Establish incident response plans specifically addressing SaaS breaches and social engineering threats to quickly detect and contain unauthorized access.
- Regularly audit connected applications and permissions to ensure that only legitimate integrations remain active [2][5].
This incident serves as a stark reminder that SaaS environments are increasingly vulnerable to social engineering and compromised third-party access, emphasizing the importance of combining technical safeguards with human awareness and procedural controls [5].
It is important to note that no core user data from Google products or internal systems were exposed in this breach [1][2][3]. Google has responded to the attack, performed an impact analysis, and begun mitigations.
As malicious campaigns are being scaled quickly, with hackers using information from past data breaches to target organizations, it is crucial for businesses to stay vigilant and follow the recommended actions to protect their sensitive data.

- The data breach at Google, caused by the ShinyHunters ransomware group, provides a cautionary tale about the vulnerability of SaaS environments to social engineering and third-party access compromises, highlighting the need for businesses to focus on both technological safeguards and employee training.
- In their angry response to the attack, Google revealed that the attackers used a voice phishing technique to impersonate IT personnel, deceiving Google employees into authorizing a malicious version of Salesforce’s Data Loader tool, ultimately leading to the theft of sensitive business contact information.
- As the cybersecurity landscape continues to evolve, businesses must acknowledge the potential risks involved with data-and-cloud-computing solutions like Salesforce and implement measures such as regular audits, strong access protocols, and vigilant monitoring to protect their sensitive enterprise data from being stolen and potentially used for ransomware attacks.
