🔒 AWS Security Agent (now part of AWS Continuum) adds support for Kiro and Claude Code, enabling developers to trigger security scans directly from their development environment. The agent now validates code scanner findings by simulating exploits in a sandbox to provide proof of exploit, reducing false positives and improving prioritization. Integrations include GitLab.com, GitLab Self Managed, GitHub Enterprise, Bitbucket, and Confluence, and features are available in all supported regions.

🛡️ Over 50 cybersecurity professionals have urged the US government to lift its export-control directive that suspended access to Anthropic’s Mythos 5 and Fable 5 LLMs. The directive, issued on June 12, led Anthropic to suspend access to both models while it complies with the government order, which cited national security concerns tied to alleged guardrail bypass research. The signees argue the ban removes valuable defensive capabilities and call for a transparent, scientific AI risk-assessment process.

🔒 Check Point now integrates its Workforce AI governance with Claude’s Compliance API to close substantial visibility gaps in enterprise AI usage. The integration provides continuous, audit-grade records across web, desktop, and mobile surfaces, addressing a critical mobile blind spot that proxies, CASBs, and endpoint DLP cannot cover. It combines content-level exposure analysis, per-user adoption analytics, and unified policy enforcement to enable secure, frictionless AI adoption across the organization.

🛡️ Cybersecurity researchers at Tenet Security disclosed a new attack class called Agentjacking that tricks AI coding agents into executing arbitrary code. The exploit leverages Sentry's public DSN and its MCP interaction to inject crafted error events, which agents like Claude Code and Cursor interpret as trusted resolution steps. Successful exploitation can expose sensitive data and run code with developers' privileges.

🛡️ This article outlines how enterprises can detect and block unauthorized AI tools—ranging from public chatbots like ChatGPT and Claude to meeting recorders and local model runners. It recommends monitoring NGFW/web-filter logs, EDR/EPP and MDM tools, browser policies, DNS reroutes, and application allowlists. The guidance covers detection indicators (domains, executables, SNI, calendar invites) and concrete lockdown steps (category blocks, policy toggles, OAuth restrictions). Emphasis is placed on offering approved alternatives and using layered controls rather than outright bans.

🤖 Anthropic has released two new models, Claude Mythos 5 and Claude Fable 5, with Mythos 5 earmarked as an upgraded frontier model for cybersecurity and initially deployed via Project Glasswing. Fable 5 uses the same core model but adds conservative guardrails, routing certain queries to Claude Opus 4.8. Both models are priced significantly lower than previous previews and Fable 5 is already available through Microsoft Foundry.

🛡️ Anthropic released Claude Fable 5 publicly on June 9, pairing it with a twin, Claude Mythos 5, that retains strong cybersecurity capabilities for vetted defenders. Fable 5 routes flagged cyber, bio, chemistry, and distillation requests to the weaker Opus 4.8 using safety classifiers, while Mythos 5 keeps those abilities available under trusted access. Both models are priced per input/output tokens and included on paid plans through June 22 before moving to usage credits.

🔒 Anthropic has released Fable 5, a safer variant of its powerful Mythos-class model, intended to reduce misuse by blocking sensitive cybersecurity, biology, and chemistry queries. The company will route restricted prompts to Opus 4.8, while the unrestricted Claude Mythos 5 remains limited to highly vetted partners. Fable 5 is free temporarily for Pro, Max, and Enterprise users until June 22 but consumes tokens much faster than other models.

🛡️ Anthropic released two Mythos-class models: the broadly available Claude Fable 5 and the restricted Claude Mythos 5 for select cybersecurity and infrastructure partners. Anthropic says Fable 5 outperforms prior Claude models across coding, research, vision, and long-form tasks while routing risky queries to a fallback, Claude Opus 4.8. The company stresses conservative safeguards to prevent misuse, but early tests suggest some benign cyber tasks are also being rerouted.

🟢 Claude Fable 5, Anthropic’s latest frontier model, is now generally available on Google Cloud. The model is designed for complex, multi-step reasoning and supports demanding use cases like advanced software development, long-horizon agents, and deep multimodal document analysis. Google Cloud highlights strong safeguards to make the model suitable for general use and positions it alongside other Anthropic offerings on the Agent Platform.

🚀 Claude Fable 5 is now available in Microsoft Foundry, powering agents across GitHub Copilot and the Foundry Agent Service to tackle long-running, multi-stage tasks such as complex refactoring, research synthesis, and document-heavy workflows. Foundry adds enterprise-grade security, governance, and operational controls to help organizations evaluate, deploy, and scale autonomous systems in production. Anthropic and Microsoft combine safeguards, guided guardrails, and observability to support responsible use while enabling powerful multimodal reasoning and continuous agent improvement.

🛠️ Nearly all software teams now use AI coding assistants, yet fewer than a third have formal governance in place. A UserEvidence survey for Black Duck of 831 developers and DevOps pros in March 2026 found 97% adoption but only 30% with full oversight. Popular tools include GitHub Copilot (83%) and Claude Code (63%). Teams report faster releases and an average of eight hours saved per developer weekly, but many face downstream friction in reviews, testing and rework.

🛡️ Microsoft Threat Intelligence describes campaigns that impersonate popular AI platforms such as ChatGPT, Copilot, and Claude to lure victims via phishing, malvertising, and SEO abuse. These operations use trusted branding, redirect chains, and urgency-driven messaging to steal credentials, commit fraud, or deliver malware. The blog emphasizes abuse of brand names rather than service compromise and recommends leveraging AI-powered security for detection and response.

🧭 Microsoft has released an open-source fork of Windows Terminal named Intelligent Terminal, enabling AI assistance directly within the terminal without disrupting active sessions. The assistant can explain errors, draft commands, and propose fixes while remaining aware of current and past agent sessions. Users choose an AI agent (examples include GitHub Copilot, Claude, Codex, and Gemini) and can toggle Automatic error detection, Automatic error suggestion, and Session management. The terminal shows an AI pane beneath the shell for interactive planning, edits, and session resume features.

🔒 Researchers disclosed an attack chain against Anthropic’s command-line coding assistant, Claude Code, that abuses the Model Context Protocol (MCP). A malicious npm post-install hook can rewrite the local ~/.claude.json configuration to redirect authenticated MCP traffic to attacker infrastructure, allowing interception of stored OAuth bearer tokens. Anthropic has been notified but has not issued a patch; defenders are advised to monitor the configuration file, treat npm post-install hooks as high risk, and rotate OAuth tokens tied to Claude Code integrations.

🛡️ Anthropic has broadened Project Glasswing, giving 150 additional organizations access to its most capable model, Claude Mythos Preview, to help find vulnerabilities in critical software. The program, first opened to roughly 50 partners in April, claims more than 10,000 high- or critical-severity flaws discovered to date. New participants span 15+ countries and underrepresented sectors like power, water, healthcare and hardware, chosen for the potential catastrophic impact of breaches. Anthropic warned that while discovery is accelerating, safe public release of Mythos-class models remains restricted due to incomplete safeguards.

🔧 Amazon SageMaker HyperPod now offers troubleshooting skills that deliver expert AI/ML cluster diagnostics into coding assistants like Claude Code, Cursor, and Kiro. These skills guide natural-language diagnostics for GPU hardware faults, NCCL communication issues, and performance bottlenecks across distributed clusters. They automate evidence collection via AWS Systems Manager and provide actionable recommendations without requiring infrastructure changes.

🚀 Claude Opus 4.8 is now accessible in Microsoft Foundry, providing developers and enterprises with Anthropic’s most capable Opus model for coding, agentic tasks, and professional work. The update focuses on long-running workflows, deeper reasoning across documents and codebases, and more reliable tool use for multi-step automation. Teams can now evaluate and deploy the model within Foundry’s unified platform for building and operating AI applications.

🤖 Anthropic confirmed plans to release its Mythos-class AI models to the general public after previously restricting access because of security risks to public and private software. Initially available only to select organizations and researchers, Mythos was held back while Anthropic developed stronger safeguards. The company says it’s making swift progress and expects to offer Mythos-class models to customers in the coming weeks, noting significant gains in code reasoning and autonomy over its Opus 4.8 flagship.

🔒 Cisco researchers warn that safety guardrails in several leading large language models (LLMs) can be bypassed through multi-turn conversations. They tested frontier models including ChatGPT, Claude, Gemini, Nova and Grok, finding many were susceptible to manipulation that yields disallowed outputs. Techniques such as roleplay, ambiguity, reframing, and persona adoption were effective, and model configuration affected resilience.
