This week brings significant developments in cloud security, from the massive $4 billion acquisition marking the largest cloud security consolidation move of 2025 to critical vulnerabilities in Microsoft Azure DevOps and SAP NetWeaver.

Our featured discussion with Jackie Bow (Technical Lead, Threat Detection Engineering at Anthropic) and Kane Narraway (Enterprise Security Lead at Canva) provides timely insights into how security teams can leverage AI for detection and response while properly securing AI systems themselves.

📰 THIS WEEK'S SECURITY NEWS

💰 Zscaler Acquires Red Canary for $4 Billion in Major Cloud Security Consolidation

Zscaler announced a definitive agreement to acquire managed detection and response leader Red Canary for an estimated $4 billion, combining Zscaler's 500 billion daily transaction processing capability with Red Canary's threat detection expertise and 200+ security tool integrations. The deal promises 10x faster threat investigation with 99.6% accuracy through AI-powered workflows.

Why It Matters: This acquisition represents the largest cloud security consolidation move of 2025, signaling industry maturation toward unified platforms that combine network security, identity protection, and managed detection capabilities. As Jackie Bow noted in our discussion, traditional SIEMs have been "black boxes" that generate false positives - this consolidation suggests the market is moving toward more transparent, AI-enhanced detection platforms. Enterprise security teams should evaluate whether unified platforms can reduce operational complexity while maintaining security efficacy, and assess current MDR relationships in light of potential industry-wide consolidation effects.

🚨🫣 Microsoft Releases 78 Security Patches Including CVSS 10.0 Azure DevOps Server Vulnerability

Microsoft's May 2025 Patch Tuesday addressed 78 vulnerabilities, including a maximum-severity privilege escalation flaw in Azure DevOps Server (CVE-2025-29813) and five actively exploited zero-days affecting Windows components. The Azure DevOps vulnerability allows unauthorized attackers to elevate privileges over a network without authentication.

Why It Matters: This CVSS 10.0 vulnerability represents a critical threat to enterprise development infrastructure, enabling complete system compromise through network-based attacks. While cloud-hosted Azure DevOps instances have been automatically patched, on-premises deployments require immediate attention. As Kane Narraway emphasized in our discussion about securing AI development tools, the attack surface expands when AI systems connect to development infrastructure. Cloud security teams must prioritize patching for internet-facing systems and implement enhanced monitoring for Windows Common Log File System activity.

🚨🫣  GitLab Duo AI Assistant Exploited via Hidden Prompt Injection for Source Code Theft

Security researchers disclosed a remote prompt injection vulnerability in GitLab Duo that allowed attackers to steal private source code and inject malicious HTML through hidden prompts embedded in merge requests, commit messages, and issue comments. The AI assistant, powered by Anthropic's Claude, could be manipulated to exfiltrate confidential information using techniques like Base16 encoding and invisible KaTeX formatting.

Why It Matters: This vulnerability exposes the expanding attack surface created by AI-powered development tools that process user-controlled content without sufficient input validation. As Jackie Bow noted, "we want models to hallucinate a bit within boundaries" for creative investigation, but this incident shows how that capability can be weaponized. The ability to manipulate code suggestions and exfiltrate private repositories represents a critical supply chain risk. Organizations should implement strict boundaries around AI tool access to sensitive repositories and establish monitoring for unusual code suggestion patterns.

🚨 Oracle Cloud Infrastructure Faces Continued Scrutiny Over Unconfirmed Breach Claims

CISA issued warnings about potential data breach risks following unconfirmed reports of Oracle Cloud Infrastructure compromise, as alleged attackers continue to market stolen credentials and enterprise data on underground forums. While Oracle maintains no breach of Oracle Cloud occurred and that published credentials are not from Oracle Cloud systems, CISA warned that the "nature of the reported activity presents potential risk to organizations and individuals, particularly where credential material may be exposed, reused across separate, unaffiliated systems, or embedded."

Why It Matters: Regardless of Oracle's denials, the potential exposure of enterprise credentials creates immediate risk requiring proactive response from cloud security teams. Organizations should rotate passwords and authentication tokens for Oracle-connected systems, implement multi-factor authentication, and audit access logs for suspicious activity. The incident highlights risks posed by legacy infrastructure components that may not receive regular security updates. The conflicting narratives between CISA warnings and Oracle denials underscore the importance of independent verification and not relying solely on vendor assurances during potential security incidents. Cloud security teams should inventory all Oracle dependencies, ensure proper credential hygiene across cloud environments, and prepare incident response procedures for potential credential compromise scenarios.

☠️ 👕 SUPPLY CHAIN BREACH: Adidas Customer Data Exposed via Third-Party

What Happened: "adidas recently became aware that an unauthorized external party obtained certain consumer data through a third-party customer service provider," the company said on Friday. The stolen information did not include the affected customers' payment-related information or passwords, as the threat actors behind the breach only gained access to contact. The affected data "mainly consists of contact information relating to consumers who had contacted our customer service help desk in the past."

Why It Matters: This incident exemplifies the growing third-party risk in cloud environments. According to the Verizon 2025 Data Breach Investigations Report, 30% of breaches in the past year involved third-party entities, double the percentage from the previous year. Cloud security teams must implement stronger vendor risk management programs and continuous monitoring of third-party access to customer data. The breach demonstrates how customer service platforms can become attack vectors for accessing sensitive information.

CLOUD SECURITY TOPIC OF THE WEEK

The AI Security Revolution Continues: AI-Powered Detection & Response Meets Enterprise Reality

Leveraging AI for Cloud Security Detection While Securing AI Systems: A Dual Perspective

Featured Experts This Week 🎤

• Jackie Bow - Technical Lead, Threat Detection Engineering Platform at Anthropic

• Kane Narraway - Enterprise Security Team Lead at Canva

• Ashish Rajan - CISO | Host, Cloud Security Podcast

Definitions and Core Concepts 📚

Before diving into our insights, let's clarify some key terms:

• Model Context Protocol (MCP): An open standard for writing connectors that provide AI agents with actions and integrations to external systems, enabling tool use capabilities.

• Vibe Coding: A term describing the practice of using AI coding assistants to rapidly prototype and develop solutions through natural language prompts and iterative refinement.

• SIEM (Security Information and Event Management): Traditional security platforms that collect, analyze, and correlate security events, often criticized for generating excessive false positives.

• Threat Detection Engineering: The practice of developing, testing, and maintaining detection rules and signatures to identify malicious activity in security telemetry.

• YOLO Mode: A reference to AI coding tools that can autonomously make changes with minimal human oversight - "You Only Live Once" mode where developers grant broad permissions to AI agents.

💡Our Insights from this Practitioner 🔍

1 - The Evolution from Black Box to Transparent AI Detection

Traditional security has been plagued by "black box" detection systems that generate alerts without clear reasoning. Jackie Bow provided a compelling perspective on how modern AI changes this paradigm: "The difference in right now leveraging AI is instead of a black box of like, alerts go in and something gets spit out and you have no idea how it got there... with these models that have extended thinking, you can actually see what prompts go in. You can tweak those prompts."

This transparency represents a fundamental shift in security operations. Unlike legacy SIEM solutions that have been "selling this idea of AI powered, like machine learning detection response" as "hot garbage" for years, current LLMs offer visibility into their reasoning process. Security teams can now implement "best of n" approaches, where the same prompt triages a detection multiple times, allowing operators to choose the best response.

Practical Application: Start by identifying your highest-volume, lowest-confidence alerts. Implement AI triage using tools like Claude Code to process these signals, maintaining human oversight for high-confidence detections while allowing AI to surface interesting patterns from background noise.

2 - Embracing Controlled Hallucination for Creative Investigation

Perhaps the most counterintuitive insight from our discussion was Jackie Bow's perspective on AI hallucination: "We actually want the model to break out of like playbook, style, or rigid human thinking and have creativity because any of us who are incident responders... know that most of the times our most like incredible ideas come when we're doing things creatively."

This challenges the conventional wisdom that hallucination is purely negative. In incident response and threat hunting, creative thinking often leads to breakthrough discoveries. The key is establishing boundaries - encouraging investigative creativity while preventing fabrication of evidence.

Practical Application: When designing AI-assisted investigation workflows, explicitly prompt models to suggest unconventional investigative paths while clearly defining what constitutes acceptable "creative" suggestions versus prohibited fabrication of log data or network events.

3 - Threat Modeling AI Systems: Focus on Access and Integration Points

Kane Narraway provided practical guidance for threat modeling AI systems, emphasizing two critical areas: "I like to focus on sort of two areas... how are you interacting with them? What are, desktops, phones, like where are you accessing them from?... And then on the other end, what integrations do you have? So what is your AI talking to?"

This approach recognizes that AI systems amplify existing security risks rather than creating entirely new threat categories. The most significant risks emerge at access points (how users interact with AI) and integration points (what systems AI can access).

Practical Application:

1. Access Control: Implement strong authentication for AI tools, especially those with elevated privileges or access to sensitive data

2. Integration Security: Catalog all AI tool integrations and apply the principle of least privilege to each connection

3. Monitoring: Focus detection efforts on unusual API calls or data access patterns from AI-integrated services

4 - The Reality of Scaling Security Teams with AI

Both experts emphasized that security teams cannot scale at the pace of engineering organizations without leveraging AI. Kane Narraway made this point clearly: "Security teams don't really scale with engineering departments generally... If your engineers are doing it, then like you are going to fall further and further behind."

Jackie Bow reinforced this with a call to action: "We are not going to be able to keep up as defenders if we are not willing to use this technology."

Practical Application: Rather than waiting for "perfect" AI security tools, start with low-risk experimentation:

• Use AI for log analysis and pattern detection in sandbox environments

• Implement AI-assisted threat hunting for historical data investigation

• Automate routine security tasks like vulnerability assessment report generation

• Create AI-powered security training scenarios for team skill development

5 - Building Engineering-Forward Security Stacks

Jackie Bow emphasized the importance of technical architecture that enables AI integration: "Set up your technical stack. So it is engineering forward because models you can think of as software engineers, you give them tools to use and their efficacy is how open your stack is."

This means prioritizing tools with well-documented APIs, open standards like Sigma rules, and common programming languages that AI models can effectively utilize.

Practical Application: When evaluating security tools, prioritize those offering:

• Comprehensive API documentation and programmatic access

• Support for open detection standards (Sigma, YARA, etc.)

• Integration capabilities with common development tools

• Clear logging and audit trails for AI-generated actions

6 - Balancing Innovation with Risk Management

The discussion revealed a tension between security innovation and risk management. While Jackie advocated for rapid experimentation ("I'm on team, build more sh*t"), Kane provided the necessary counterbalance with structured threat modeling and focused risk assessment.

This balance is crucial for organizations wanting to leverage AI without introducing unacceptable risk. The key is graduated implementation - starting with low-risk use cases and expanding as confidence and controls mature.

Practical Application: Implement a three-tier approach:

1. Tier 1: AI tools for analysis of historical data and non-production environments

2. Tier 2: AI-assisted detection and response with human oversight for production systems

3. Tier 3: Autonomous AI actions only after extensive testing and with robust monitoring
