In a shocking turn of events, Microsoft, a global tech giant renowned for its advancements in Artificial Intelligence (AI), found itself in an embarrassing situation when its AI research team accidentally leaked a staggering 38 terabytes (TB) of the company’s private data. This colossal data breach, first discovered by cloud security company Wiz on GitHub, has raised concerns about data security in the era of advanced AI research.
The Contents of the Microsoft Leaks
The leaked data, part of the Microsoft leaks incident, included complete backups of two employees’ computers, which contained a treasure trove of sensitive personal information. Among the exposed data were passwords to various Microsoft services, secret keys, and over 30,000 internal Microsoft Teams messages involving more than 350 Microsoft employees. This breach shed light on the potential vulnerabilities that even tech giants like Microsoft can encounter when handling vast amounts of data.
How Did the Microsoft Leaks Occur?
The inadvertent Microsoft leaks occurred as a result of Microsoft’s AI research team’s attempt to upload a bucket of training data that contained open-source code and AI models for image recognition. Users who stumbled upon the GitHub repository were provided with a link from Azure, Microsoft’s cloud storage service, to download these AI models. However, a critical error in the configuration of this link led to disastrous consequences.
The link shared by Microsoft’s AI team inadvertently granted visitors complete access to the entire Azure storage account. This meant that not only could visitors view the contents of the account, but they could also upload, overwrite, or delete files at will.
The core issue revolved around an Azure feature known as Shared Access Signature (SAS) tokens, which are essentially signed URLs that provide access to Azure Storage data. In this instance, the SAS token had been configured with full access, opening the door to this massive data breach.
Microsoft’s Response and Resolution to the Microsoft Leaks
Upon discovering the issue in the Microsoft leaks case, Wiz promptly contacted Microsoft to alert them to the data breach. On June 22, Microsoft took swift action by invalidating the problematic SAS token, effectively closing the security loophole. Following this, Microsoft conducted a comprehensive investigation into the potential impacts of the data leak, which they completed by August.
Crucially, Microsoft has provided reassurance to its customers that no customer data was compromised in the breach. Additionally, no other internal services were put at risk as a result of this issue. This rapid response and transparency demonstrate Microsoft’s commitment to addressing security incidents and safeguarding the interests of its users.

Lessons Learned and Best Practices from the Microsoft Leaks Incident
In the aftermath of this high-profile data breach, Microsoft has shared its learnings and best practices to inform its customers and help them avoid similar incidents in the future. These insights not only serve as a valuable resource for Microsoft users but also offer important lessons for organisations across industries when it comes to data security.
The incident underscores the importance of rigorously reviewing and configuring access control mechanisms, especially in cloud storage environments. Shared Access Signature (SAS) tokens, while a powerful tool, must be carefully managed and restricted to the necessary permissions to prevent unauthorised access.
Moreover, organisations should implement regular security audits and assessments to identify potential vulnerabilities before they can be exploited. In this case, a prompt response from Wiz played a crucial role in mitigating the damage.

Conclusion on the Microsoft Leaks
The accidental Microsoft leaks of 38TB of data by Microsoft’s AI research team serves as a stark reminder of the critical importance of data security in the digital age. Even tech giants like Microsoft are not immune to such breaches, highlighting the need for constant vigilance and proactive measures to protect sensitive information.
Microsoft’s swift response, resolution of the issue, and commitment to transparency in reassuring its customers have set an example for how organisations should handle such incidents. While the incident itself is a significant setback, the lessons learned and best practices shared can ultimately help strengthen data security measures for Microsoft and organisations worldwide.
In an era where data is increasingly invaluable and vulnerable, this incident serves as a powerful wake-up call for the tech industry and beyond, urging all stakeholders to prioritise data security in their operations and to learn from the mistakes of even the largest players in the field.
Frequently Asked Questions
What Specific Types of Sensitive Information Were Exposed in the Data Breach?
In the data breach, sensitive information such as passwords to various Microsoft services, secret keys, and more than 30,000 internal Microsoft Teams messages from over 350 Microsoft employees were exposed. This included a wide range of confidential data, from access credentials to internal communication, potentially putting both individual and organisational security at risk.
What Actions Did Microsoft Take to Address the Data Breach Once It Was Identified?
Microsoft responded promptly upon being alerted to the data breach by invalidating the Shared Access Signature (SAS) token that had been misconfigured, thus closing the security loophole. Subsequently, the company conducted a thorough investigation into the incident, which was completed by August. Microsoft’s swift action in resolving the issue and their commitment to transparency in communicating with customers demonstrated their dedication to addressing security incidents.
Has Microsoft Implemented Any Additional Security Measures or Protocols to Prevent Similar Data Leaks in the Future?
While the article does not provide specific details on additional security measures, Microsoft has shared its learnings and best practices to help customers avoid similar incidents. These insights likely include recommendations for configuring access control mechanisms more rigorously, conducting regular security audits, and ensuring the appropriate management of SAS tokens. It’s reasonable to expect that Microsoft has also taken internal steps to enhance data security to prevent future breaches.
