Introduction


In December 2024, PowerSchool, a major K-12 operations platform, suffered a devastating data breach. Attackers exploited compromised credentials on PowerSchool’s support platform, potentially exposing sensitive information of students and staff across the US and Canada. The breach included names, addresses, Social Security numbers, medical records, and grades. Attackers exploited a compromised credential tied to a maintenance account to access PowerSchool’s Student Information System via the PowerSource customer support portal.PowerSchool serves over 45 million students across more than 90 countries and is used by more than 15,000 school districts, making it one of the most widely adopted educational technology providers in North America. The scale of the breach significantly heightened concerns across the K–12 sector, especially given the sensitivity of the data involved.


Even after paying a ransom, there was no guarantee that the stolen data wouldn’t resurface. The incident highlighted a painful reality: many organizations are unknowingly vulnerable to a deceptive threat—data leaks. These leaks, stemming from accidental exposures, misconfigurations, or human error, can be just as damaging, and in some cases, even more so.


Data leaks refer to the unintentional exposure of sensitive or confidential information, often due to misconfigurations, human error, or insecure third-party integrations. Unlike deliberate breaches, data leaks typically occur without the organization’s knowledge—leaving sensitive assets like credentials, customer data, or internal documents vulnerable to unauthorized access.


Today’s organizations rely on cloud platforms like Cloud Storage like Amazon S3 to store critical data, but misconfigured access controls or careless handling of credentials can lead to dire consequences.


Causes of Data Leaks


Misconfigurations and accidental exposures are among the leading causes of data leaks. Cloud storage services such as Amazon S3, Azure Blob Storage, and Google Cloud Storage are common sources for the unintentional release of sensitive data such as API keys, database credentials, and internal documentation. For example, a developer might mistakenly configure access permissions on a cloud storage bucket to be public instead of private, or fail to apply proper identity and access management (IAM) controls, inadvertently exposing the data to the internet. An employee could also misconfigure a storage bucket while transferring data for cross-team access, accidentally overriding default security settings and leaving business-critical data open to unauthorized access.


Human error is by far the most common cause of data leaks. According to Microsoft, one of the primary vectors for data leaks is poor security practices, such as storing confidential information in unsecured locations, falling victim to phishing attacks, or mishandling credentials. Moreover, third-party breaches and weak authentication further worsens the risks.


The GenAI Factor: A New Layer of Risk


The advent of generative AI (GenAI) has only intensified these risks. According to Gartner, by 2027, over 40% of AI-related data breaches will be caused by cross-border misuse of GenAI technologies. As AI tools are integrated into business operations, they inadvertently increase the chances of sensitive data being processed and shared in regions with less stringent data protection regulations. These AI-driven systems can send prompts to servers in unregulated jurisdictions, leading to accidental data leaks.


Organizations must act swiftly to adopt AI governance strategies and implement robust security protocols to ensure compliance and protect sensitive data. Effective governance should include monitoring public sources and environments where large language models (LLMs) are typically used. This is because they can often be points where sensitive data is inadvertently exposed and failure to do so could result in costly regulatory penalties, legal consequences, and severe reputational damage.


The report also highlights that organizations deploying security AI and automation extensively experienced an average reduction of $2.2 million in breach costs compared to those without these technologies. Many of these could have been prevented with proactive monitoring.


Without real-time visibility, your IT team is left playing defense—only discovering vulnerabilities once they’ve already been exploited.


How To Prevent Data Leaks:


Preventing data leaks requires a comprehensive approach to both technology and process. While organizations can take steps to identify and respond to leaks, they often need a proactive, advanced solution to stay ahead of evolving threats.


- Employee Training: Ensuring your workforce is aware of data security best practices is crucial. This includes understanding the risks associated with cloud storage misconfigurations, handling credentials securely, and avoiding phishing attacks. By educating your team on how to properly handle sensitive information and spot potential threats, you can significantly reduce the risk of data leaks caused by human error.


- Automated Scanning for Exposed Credentials: Monitoring of public cloud storage repositories and other online platforms is essential to identifying exposed credentials, API keys, and other confidential data. Automated scanning ensures that any sensitive information unintentionally left in public spaces is discovered quickly, enabling swift action to prevent further exposure. This step is the most important because exposed credentials are often the fastest and easiest way for attackers to gain unauthorized access to systems. Without immediate identification, a single leaked credential can compromise entire networks in minutes.


- Proactive Misconfiguration Detection: Misconfigurations are a leading cause of accidental data leaks. Identifying misconfigured cloud storage buckets, repository settings, or access controls is key to preventing exposure. With the right tools in place, organizations can proactively detect and address these vulnerabilities before they result in costly leaks.
