OVH used its Sydney, Australia datacenter as a crash test dummy to test a rapid fix rollout for the critical Januscape guest-host escape bug. Januscape, CVE-2026-53359, allowed attackers with root access to a guest VM to execute code as root on the host, crash that machine, or take over all other guest VMs. The fix involves mass reboots.
Researchers found sandbox escapes or boundary bypasses in Cursor, Codex, Gemini CLI, and Antigravity by writing files trusted tools later use. Most of the vulnerabilities are patched.
Estée Lauder disclosed a data breach after hackers exploited a vulnerability in Oracle E-Business Suite used for HR operations. The intrusion occurred on August 9, 2025, exposing personal information including bank account numbers and payroll data. The company offers 24 months of identity monitoring through Kroll.
Attackers are exploiting two WordPress vulnerabilities chained together for pre-authentication remote code execution. Security researchers reproduced CVE-2026-63030 within minutes of disclosure. The bugs were likely reproduced with AI assistance, according to watchTowr principal security researcher Jake Knott.
NodeMeta is building a connected digital economy around its NTE token on BNB Smart Chain. The ecosystem includes OneKey, a unified Web3 dashboard, and TrustScan AI, a security and token-verification platform. NodeMeta plans to burn up to 40% of the 11 billion NTE supply and pursue over 30 exchange listings within three years.
JadePuffer, an autonomous AI agent, now uses custom EncForge ransomware to encrypt AI assets like training datasets and model checkpoints. The Go-based binary targets 180 file extensions across the AI/ML stack. Sysdig reports the attacker breached a Langflow instance vulnerable to CVE-2025-3248 and deployed six Python scripts in five minutes to deliver the payload.
Cloudflare Internal DNS is now generally available, providing authoritative and recursive DNS for private networks on the same global network as public DNS and Zero Trust. Enterprise customers get it included with Cloudflare Gateway at no extra charge. The service consolidates split-horizon DNS into a single control plane.

Taiwanese prosecutors indicted a former TSMC deputy manager surnamed Chen for copying 21 confidential documents, including national core technologies, intending to use them in China. TSMC recovered all documents after internal monitoring flagged the theft. Prosecutors seek up to seven years in prison, marking the first indictment under Taiwan's National Security Act for alleged chip technology leaks to China.
Researchers from Zhejiang University devised Bit2Watt, an attack where malicious cloud tenants use GPU workloads to destabilize datacenters and electrical infrastructure. The attack can induce voltage excursions, harmonic distortion, and damping degradation. A 1,000-GPU assault on a 1-MW grid could create 46.8 percent total harmonic distortion, potentially triggering cascading failures and blackouts exceeding 80 percent.
Hugging Face was attacked by a fully autonomous AI agent that swarmed its system with tens of thousands of automated actions. The company fought back using Chinese model Z.ai's GLM 5.2 after a leading U.S. AI model's guardrails prevented it from examining malicious payloads. CEO Clem Delangue said open models are necessary for defense.
Apricorn released a 4TB Aegis Secure Key 3, the highest-capacity hardware-encrypted USB drive of its kind. It uses AES-256 XTS quantum-resistant encryption, is IP68 rated, crushproof to 6,500 pounds, and costs $3,000. Lower capacities start at $169.
Rapid7 found an exposed server containing 1,048 files from a WebDAV malware campaign targeting Windows users in Mexico. The operator used an open-source AI coding tool called Coderrr to build and test phishing delivery. One live campaign delivered an infostealer through a fake Mexican government ID-lookup site.
