Microsoft's March Patch Tuesday has addressed a staggering 57 security vulnerabilities, including six zero-day flaws already being actively exploited in the wild. The patches cover critical remote code execution bugs and privilege escalation vulnerabilities that pose significant threats to organizations using Microsoft products.
Understanding Key Trends:
- The six actively exploited zero-days primarily affect core Windows file system components, creating multiple attack vectors for malicious actors.
- Threat actors are chaining vulnerabilities to achieve both information disclosure and remote code execution capabilities.
- The exploitation patterns suggest sophisticated attackers targeting specific entities rather than widespread campaigns.
Actionable Advice:
- Prioritize applying Microsoft's latest patches immediately, with special focus on the six actively exploited vulnerabilities.
- Review your security controls around VHD files, as several vulnerabilities exploit malicious virtual disk files.
- Implement advanced threat protection solutions that can detect exploitation attempts against these vulnerabilities.
The Reality of Zero-Days:
Zero-day vulnerabilities remain the ultimate prize for threat actors, providing a window of opportunity before patches are developed and deployed. The presence of six actively exploited zero-days in a single month is alarming and indicates a troubling escalation in the sophistication of attacks. Of particular concern is the exploitation of core Windows file system components, which are foundational to the operating system's security model.
What to Expect:
With CISA adding these vulnerabilities to their Known Exploited Vulnerabilities (KEV) catalog and mandating federal agencies to patch by April 1, we'll likely see increased scanning and exploitation attempts on unpatched systems. The connection to threat actors like EncryptHub suggests that these vulnerabilities may be leveraged in broader campaigns targeting specific industries or regions.

2. Apache Tomcat Vulnerability Exposes Servers to Remote Code Execution
Summary:
A critical vulnerability in Apache Tomcat (CVE-2025-24813) has been disclosed, exposing servers to remote code execution, information disclosure, and data corruption risks. The flaw stems from improper handling of partial HTTP PUT requests and affects multiple versions of the widely used web server.
Key Implications:
- The vulnerability allows attackers to bypass security controls and write files outside intended directories.
- Malicious actors could potentially overwrite configuration files or JSPs, enabling code execution.
- Even with default configurations, data corruption and information leakage remain possible.
Actionable Advice:
- Upgrade immediately to the patched versions: Tomcat 11.0.3, 10.1.35, or 9.0.98.
- If upgrading isn't feasible, disable partial PUT requests by setting allowPartialPut="false" in the DefaultServlet configuration.
- Ensure the default servlet's readonly parameter remains true to block unauthorized writes.
Broader Implications for Web Infrastructure:
This vulnerability highlights the ongoing challenges in securing web infrastructure components that are often overlooked in security assessments. The Tomcat vulnerability is particularly concerning because it affects a component widely used across industries, from financial services to healthcare. The path traversal aspect of this vulnerability demonstrates how seemingly minor implementation details can lead to catastrophic security failures.
Analyzing Trends:
We're seeing an increasing focus on targeting web server infrastructure rather than application-level vulnerabilities. This shift suggests attackers are moving lower in the technology stack, recognizing that vulnerable infrastructure components offer more persistent access than application-level flaws. Organizations must expand vulnerability management beyond custom applications to include all infrastructure components.

3. Amazon Continues Hosting Stalkerware Victims' Data Despite Breach Notification
Summary:
Amazon Web Services is reportedly still hosting data exfiltrated by stalkerware operations Cocospy, Spyic, and Spyzie weeks after being notified of the issue. These surveillance apps have exposed the private phone data of approximately 3.1 million victims, with the stolen information stored in Amazon's cloud storage buckets.
Setting the Stage:
- Stalkerware applications are covertly installed on victims' devices to monitor their activities without consent.
- Major cloud providers like AWS have terms of service prohibiting such malicious activities.
- Victims' private photos and other sensitive data continue to be accessible via AWS storage.
Why You Should Care:
When technology giants fail to take action against abuse of their platforms, it enables the continued victimization of individuals whose privacy has already been violated. For businesses, this highlights the importance of vetting cloud storage solutions and understanding how providers respond to abuse reports involving their infrastructure.
Broader Implications for Cloud Security:
This situation exposes a critical gap in cloud service provider accountability. While AWS has policies against hosting malicious content, their reluctance to act on reported violations raises questions about the effectiveness of self-regulation in the cloud industry. For organizations, this should prompt a reevaluation of which cloud providers they trust with sensitive data and what remediation processes are in place when abuse is discovered.
Counteractive Measures:
- Organizations should review their cloud providers' abuse response policies and historical actions against malicious actors.
- Cloud customers should include specific language in contracts regarding provider responsibilities for removing malicious content.
- Consider implementing additional encryption for cloud-stored data to minimize exposure if the provider's security measures fail.

4. Multiple Organizations Report Data Breaches Affecting Sensitive Personal Information
Summary:
A wave of data breaches has hit multiple sectors this week, with Trinity Petroleum Management, Tata Technologies, updates on the PowerSchool breach and several educational institutions all reporting compromises of sensitive personal information. These incidents collectively affect millions of individuals and expose a wide range of sensitive data, from Social Security numbers to medical information.
Key Implications:
- The PowerSchool breach potentially which has affecteed around 70 million students and educators across the US and Canada has received updates that the initial breach occured months before the stolen data incident.
- Tata Technologies suffered a 1.4TB data leak orchestrated by the Hunters International ransomware group.
- Trinity Petroleum's breach exposed names, addresses, and Social Security numbers of an undisclosed number of individuals.
Actionable Advice for Organizations:
- Implement robust access controls and multi-factor authentication, especially for maintenance accounts.
