TL;DR

• •Microsoft released a massive June update patching 198 Windows bugs.
• •The update addresses three actively exploited zero-day vulnerabilities.
• •Prompt patching is critical to mitigate potential security risks for Windows users.

TL;DR

• •Cisco patched a new zero-day vulnerability in its SD-WAN software.
• •This is the sixth actively exploited zero-day impacting Cisco SD-WAN this year.
• •Organizations using Cisco SD-WAN should prioritize patching and review security configurations.

TL;DR

• •A zero-day vulnerability (CVE-2026-42897) in Microsoft Exchange is under active exploitation.
• •Mitigations are available via the Exchange Emergency Mitigation Service (EEMS) and a manual tool.
• •Full patches are planned, but availability varies based on Exchange version and support status.

TL;DR

• •A critical zero-day vulnerability in Microsoft Exchange Server is being actively exploited.
• •The vulnerability allows attackers to gain access to Exchange servers, potentially leading to data breaches.
• •Mitigation steps include applying the provided Microsoft update and monitoring for suspicious activity.

TL;DR

• •Security researchers demonstrated 15 unique zero-day vulnerabilities on day two of Pwn2Own Berlin 2026, earning over $385,000 in cash awards.
• •Major exploits included remote code execution with SYSTEM privileges on Microsoft Exchange and privilege escalation on Windows 11 and Red Hat Enterprise Linux.
• •Zero-days were also disclosed in AI coding agents like Cursor AI and OpenAI Codex, highlighting growing security concerns in emerging AI platforms.

TL;DR

• •Google has reportedly claimed that criminals utilized an AI-generated zero-day exploit in a coordinated mass hacking attempt.
• •This marks a significant, and potentially alarming, escalation in the use of artificial intelligence for offensive cyber operations.
• •While specific details about the AI models, vulnerability, or targets remain scarce, the incident highlights the urgent need for enhanced AI-driven cybersecurity defenses.

TL;DR

• •Anthropic's new LLM, Claude Mythos Preview, demonstrates 'strikingly capable' cybersecurity abilities, identifying and exploiting zero-day vulnerabilities across major OSes and web brow...
• •The model can construct highly complex exploits, including multi-vulnerability chains, JIT heap sprays, and autonomously achieve local privilege escalation via race conditions and KASLR bypasses.
• •Project Glasswing has been launched to leverage Mythos Preview for securing critical software and to prepare the industry for advanced AI-driven cyber challenges.
• •Over 99% of the vulnerabilities found by Mythos Preview are unpatched, underscoring the urgency for improved defensive strategies across the industry.
