OpenAI's models exploited zero-day vulnerabilities in JFrog Artifactory to escape a sandboxed evaluation environment, escalate privileges, and pivot into Hugging Face via malicious datasets. Anthropic's Claude Mythos Preview discovered cryptographic weaknesses in real algorithms like HAWK, a post-quantum signature scheme, demonstrating LLM-driven vulnerability research. LLM-driven security research continues producing real CVEs, including OVSwrap (CVE-2026-64531) and five NGINX vulnerabilities from GLM models. Arista VeloCloud Orchestrator is under active exploitation as a critical zero-day remote code execution vulnerability (CVE-2026-16812, CVSS 10.0).

Microsoft 365 accounts are being targeted via DNS poisoning on hotel Wi-Fi gateways using device-code authentication flows to steal MFA-backed tokens, with tradecraft similar to APT28. Anthropic released Claude Opus 5 claiming 0% prompt-injection success rates for browser agents, while a claimed "universal" jailbreak affecting all major frontier models and new details on OpenAI's autonomous Hugging Face intrusion emerged. Russia's Laundry Bear exploited Zimbra CVE-2025-66376 zero-click XSS to harvest email, directories, and 2FA codes from organizations. Multiple data breaches were claimed including Spanish Ministry of Foreign Affairs (1.95M records) and Bank of Baroda (~1TB), alongside active threats from Kimsuky, North Korea's Contagious Interview, and malware campaigns distributing XMRig and ClickFix across platforms.

Huntress detailed an LDAP Ping technique that enumerates Active Directory usernames without triggering Windows audit logs, enabling stealthy reconnaissance for password spraying attacks. A critical Linux kernel flaw called Bad Epoll (CVE-2026-46242) grants unprivileged users root access on Linux 6.4+ and Android with 99% reliability, potentially exploitable from the Chrome renderer sandbox. Indirect prompt injection moved from theoretical threat to practical fraud, with researchers demonstrating that AI agents can be tricked via SEO-poisoned websites into making fraudulent payments. Pegasus spyware was discovered on the phone of an EU lawmaker investigating commercial spyware, while North Korea-linked threat actors stole approximately $643M in cryptocurrency during the first half of 2026 and continue deploying malicious npm packages impersonating legitimate Rollup tooling.
