This report discusses the emerging risk of automated cyber warfare driven by advanced AI models capable of discovering and exploiting software vulnerabilities at machine speed. Leading AI labs have identified numerous zero-day vulnerabilities in well-reviewed codebases using high-tier AI models, but restrict access to these powerful offensive tools to a limited set of incumbents. The majority of developers receive downgraded AI tools with restrictive safety classifiers that limit their ability to fully audit and secure their code. Meanwhile, attackers leverage uncensored, open-weight AI models without such constraints, creating an asymmetric security landscape where defenders are handicapped relative to attackers. The report argues that this gatekeeping of offensive AI capabilities undermines effective defense and calls for democratizing access to advanced offensive intelligence to enable proactive security.
Microsoft has acknowledged a known issue affecting some users on Windows systems who experience delays or are blocked from opening the Microsoft Teams desktop client. The problem causes loading delays of up to two minutes or failure to open the client initially. Microsoft is investigating the root cause and has advised affected users to use Teams via web or mobile apps as a workaround. A related issue affecting Mac users' ability to join Teams calls and meetings is also under investigation. No evidence of exploitation or security breach has been reported. Microsoft is actively working on remediation.
A zero-day privilege escalation vulnerability named 'FalconFlank' affects CrowdStrike Falcon Sensor on up-to-date Windows 11 and Windows Server systems. The exploit abuses the Office malicious macros remediation feature in CrowdStrike Falcon to spawn a command prompt with SYSTEM privileges. CrowdStrike is investigating and advises disabling the Microsoft Office File Suspicious Macro Removal policy setting as a mitigation. The vulnerability has not yet been assigned a CVE ID or publicly patched. The exploit was released by a security researcher known as 'Nightmare Eclipse'.
Microsoft Exchange Online experienced an outage causing delays in sending and receiving emails from external domains, accompanied by intermittent 'Server busy' errors. The issue affected multiple mailboxes and was aggravated by anti-spam protections. Microsoft acknowledged the incident, identified contributing factors, and resolved the issue for new emails, with ongoing monitoring to confirm full resolution. No specific affected regions or user counts were disclosed.
The UK Cyber Security and Resilience Bill is currently progressing through the House of Lords with significant details still undefined. Multiple important aspects such as reporting thresholds, data centre incident factors, board accountability, staged reporting timelines, AI inclusion, and statutory powers remain to be established through secondary legislation or voluntary codes. The Bill includes a substantial penalty framework but lacks clear, finalized compliance duties, complicating organizational preparation. Some amendments have been agreed, including broader incident reporting criteria for data centres and removal of 'users of' from significance tests. AI is notably absent from the Bill's scope, and statutory regulatory powers for AI security are resisted. The Bill's framework approach is typical, but the lack of concrete, readable obligations and ongoing consultations means organizations face uncertainty in compliance planning.

HiddenLayer, an Austin-based AI security company, announced raising $100 million in Series B funding to enhance its platform for securing AI coding agents and agentic AI applications. The company focuses on runtime security capabilities to detect and prevent anomalous, unauthorized, or malicious behavior by AI agents in production environments. HiddenLayer's platform offers discovery, AI supply chain security, attack simulation, and runtime protection to ensure compliance and intellectual property protection for enterprises adopting AI. The funding will support expanding these capabilities to secure autonomous AI agents that write, review, and ship code with minimal human oversight.
AIR Security is a startup that has developed a specialized firewall designed to protect AI agents by evaluating AI skills, plugins, and MCP servers for malicious instructions, excessive permissions, and software supply chain risks. The firewall continuously monitors and analyzes AI add-ons before and after deployment to detect malicious or vulnerable components and revoke trust if needed. This addresses emerging security challenges as AI agents autonomously connect to tools, data, and services, potentially exposing enterprises to data theft, fraud, or unauthorized access. AIR Security recently emerged from stealth with $50 million in funding and aims to provide enterprises with visibility and control over AI agent supply chains.
A threat actor offered over 153 million digital scans of US and Canadian driver’s licenses on the dark web, likely stolen from the identity verification firm IDScan.net. The data includes driver’s licenses, identification cards, travel documents, and medical cards. The breach is under FBI investigation, and some stolen IDs belong to FBI agents. The identity verification platform Nexus, where the data was sold, was shut down shortly after exposure. The incident highlights risks in identity verification systems and the need for stronger data handling and breach response measures.

OpenLeash is a security tool designed to monitor and control autonomous AI agent actions by intercepting potentially risky commands. It blocks clearly dangerous actions and requests human approval when the intent of an action is uncertain. The tool acts as an authorization layer to ensure AI agents act securely and aligned with user intent, preventing unintended or harmful operations such as accidental data deletion. OpenLeash is configurable, allowing users to specify acceptable actions and thresholds for automatic approval or human intervention. While still under development, it is actively used by individuals and organizations to mitigate risks associated with AI agents operating with broad permissions but lacking human situational awareness.
