- Cavern Manticore: Exposing Iran-Linked Modular C2 Framework
Overview
- Check Point Research has identified ‘Cavern Manticore,’ an Iran-linked modular command-and-control (C2) framework used by a threat actor focusing on Israeli government and IT sectors.
- The framework is built entirely on .NET but compiled into three different output formats to evade analysis.
- Cavern Manticore is linked to Iranian MOIS actors including MuddyWater and Lyceum (OilRig subgroup).
- The modular architecture separates core communication (Cavern agent) from specialized post-exploitation modules (file manager, SQL browser, LDAP module, network recon, tunnel).
- Initial access was gained by abusing legitimate Remote Monitoring and Management (RMM) software deployment features without exploiting any software vulnerabilities.
- The framework employs anti-forensics techniques such as per-module AppDomain isolation and uncommon compilation formats to complicate reverse engineering.
- Malware samples often score very low detection rates on VirusTotal.
Impact
- Enables persistent post-exploitation by Iranian state-linked actors with capabilities including file and database browsing, LDAP querying, network reconnaissance, and tunneling.

- The system discovered 16 unknown CVEs in Windows, including four critical RCE flaws in TCP/IP kernel stack, IKE v2 service, Netlogon, and DNS API library, all patched in May 2026 Patch Tuesday.
- MDASH demonstrated high detection reliability, with 96%-100% recall on key components based on historical vulnerability cases.
- MDASH outperformed comparable AI models on the CyberGym benchmark and operates on dedicated cloud infrastructure.
- AI is integrated into remediation workflows to accelerate patch fixes, identify related issues, and target regression tests.
- Microsoft updated its Secure Development Lifecycle to incorporate AI-enabled attack techniques and continuous AI-enabled vulnerability scanning.
- MDASH integration with Microsoft Defender is in expanded preview, enabling proactive defense with faster and broader patching cycles.
Impact
- Enabled discovery and patching of critical unknown vulnerabilities before exploitation.
- Increased vulnerability detection scale and cadence, exemplified by the record 200+ CVEs patched in June 2026 Patch Tuesday.
- Improved confidence in update quality via validation and targeted rollback mechanisms.
Recommendations
- Enterprises should maintain current patching, leverage Microsoft’s AI-enabled tools like Windows Autopatch, Intune, and Defender Vulnerability Management.
- Adopt continuous, risk-based update strategies aligned with evolving AI-accelerated threat landscapes.

- Protecting Microsoft at AI Speed: How SFI Proactively Hardens Our Cloud
Overview
- Microsoft developed a multi-agent AI system to proactively evaluate and harden its cloud infrastructure at scale and speed unmatched by traditional human-led reviews.
- The system performs comprehensive, compositional risk reasoning, assessing code, configurations, identity, network, runtime context, and trust relationships holistically.
- It detects composite vulnerabilities arising from complex interplay of components, using multi-stage analysis and AI-driven ‘what-if’ security scenario simulations.
- The system continuously updates based on feedback and evolving threat intelligence, adhering to Secure Future Initiative (SFI) requirements and defense-in-depth principles.
- Employs AI-powered vulnerability discovery including exploit chaining and proof-of-concept generation capabilities.
Impact
- Enables rapid, large-scale detection of nuanced, multi-factor vulnerabilities potentially exploitable by advanced attackers.
- Moves beyond single-point checks to identify chained attack paths and weak layered defenses before exploitation.
- Accelerates security reviews from weeks to hours, enhancing Microsoft’s ability to secure hyper-scale cloud services against sophisticated threats including AI-powered adversaries.
Recommendations
- Organizations building or operating large-scale software should evaluate security posture continuously with holistic, multi-domain analysis.
- Adopt layered defense and assume-breach models to address complex attack sequences identified via AI-enhanced reasoning.
- Integrate AI-driven security tooling that supports compositional risk assessments and adapts to service-specific architectures.

- Found Fast, Fixed Slow: The Gap the AI Clearinghouse Must Close
Overview
- The new AI cybersecurity clearinghouse mandated by an executive order aims to coordinate discovery and validation of software vulnerabilities in critical infrastructure.
- AI tools can now find vulnerabilities rapidly, but significant bottlenecks remain in validating, prioritizing, patching, and deploying fixes.
- Human reviewers’ assessments often differ from AI severity ratings due to contextual factors AI cannot evaluate.
- The clearinghouse must go beyond scanning coordination to triage vulnerabilities using shared validation standards and risk-based prioritization.
- It should also develop guidelines to help open-source maintainers speed patch review and deployment, integrating AI-assisted patching.
- Emphasized is the importance of software bills of materials (SBOMs) to trace vulnerable components and enable faster remediation.
- Success metrics should prioritize patch deployment and remediation rather than discovery volume.
Impact
- Without effective triage and patch coordination, AI-driven vulnerability discovery may increase backlogs rather than improve security.
- Critical infrastructure remains at risk if patches are not validated, accepted, and applied swiftly.
Recommendations
- Design the clearinghouse to include credible triage and prioritization, not just vulnerability scanning.
- Collaborate structurally with private sector and open-source security communities experienced in vulnerability management workflows.
- Develop guidelines with NIST to assist maintainers in using AI-assisted patching and clarify downstream remediation responsibilities.
- Use SBOMs as core infrastructure to map vulnerabilities across the supply chain.
- Track and publish metrics on validation rates, time-to-patch, and fix adoption to improve response processes.

- 6th July – Threat Intelligence Report
Overview
- Check Point Research demonstrated a browser-native ransomware technique generated by a large language model that abuses Chrome’s File System Access API, enabling encryption and exfiltration of photos on Android and Windows via a fake image-enhancement page.
- Researchers found shell command injection vulnerabilities in 10 out of 11 popular open-source AI coding agents, with obfuscated destructive commands bypassing filters and causing actions such as file deletion.
- Attackers exploited LLM phantom squatting by registering AI-generated domains (250,000 hallucinated domains recorded) to hijack traffic and deliver phishing campaigns, including the AI-built Montana Empire phishing kit using a postal-service domain for credential theft.
Impact
- Potential for AI-generated ransomware and phishing attacks causing data loss and credential theft.
- Destructive commands in AI coding agents expose users to manipulation and data compromise.
- Increased risk of phishing and domain hijacking through AI-generated domain registrations.
Recommendations
- Employ endpoint and IPS protections capable of detecting novel AI-generated threats.
- Audit and restrict permissions granted to browser applications, especially file system access.
- Review and update AI coding tools for command parsing and injection filtering.
- Monitor for and mitigate phishing campaigns leveraging AI-generated domains.
