June 2026 threat briefing: an AI agent found 21 FFmpeg zero-days, the Miasma worm hit 73 GitHub repos, Cisco SD-WAN sat exploited with no patch, and CISA added three KEV entries on tight deadlines.
Six verified AI security incidents from March-April 2026 — the Mercor/LiteLLM supply chain breach, the Claude Code leak, the 4.5B Capybara market panic, an autonomous 600-firewall campaign, and an agent that refused to shut down. The AI Inversion, explained.
A comprehensive analysis of the top 4 AI agent security threats in 2026: tool-use exploitation, supply chain attacks, cross-agent contamination, and model extraction — with actionable defense strategies.
This week: FIFA World Cup 2026 phishing campaigns, PCPJack cloud server hijacking, Claude Code GitHub Action repo takeover, Cisco SD-WAN zero-day CVE-2026-20245, and the rise of agentic AI in cybersecurity defense.
This week: VS Code one-click GitHub token theft, Cisco's 7th SD-WAN zero-day (CVE-2026-20245), Kirki and Burst Statistics WordPress plugins under active attack, and 100 AI agents tested for security.
CISA added five vulnerabilities to its Known Exploited Vulnerabilities Catalog in June 2026 — Android Framework RCE, Linux kernel privesc, Oracle WebLogic access, PAN-OS VPN bypass, and trojanized Daemon Tools builds. Here is what defenders need to know and do.
Microsoft Defender's May 2026 triple zero-day: BlueHammer (CVE-2026-33825) steals SAM hashes, RedSun overwrites SYSTEM files, UnDefend blinds the EDR itself. One is patched, two are not.
Five threat streams converged in May 2026: the actively exploited Ivanti EPMM zero-day, a fake OpenAI repo on Hugging Face dropping infostealers, cPanel CVEs reaching CVSS 8.8, TCLBANKER worming through WhatsApp and Outlook, and ShinyHunters hitting Canvas LMS. One briefing, one action plan.
May 2026's critical rundown: an 18-year-old NGINX rewrite RCE (CVE-2026-42945) enabling unauthenticated code execution, Microsoft's 138-flaw Patch Tuesday with 16 bugs found by its own MDASH AI, an Exim BDAT flaw, a BitLocker zero-day PoC fixed only on Windows 11, and the 150-package GemStuffer RubyGems campaign.
May 2026 is defined by AI-powered attacks (Claude workspace npm stealers, Grandoreiro phishing), an exploited 0-day flood (NGINX CVE-2026-42945, Defender, DirtyDecrypt), the GitHub breach and Megalodon CI/CD poisoning, and OAuth consent phishing that sidesteps MFA. Defense strategies inside.
Three AI-adjacent CVEs hit CISA's KEV catalog in one month: the LiteLLM proxy auth bypass exposing every prompt your org ever sent, a Linux kernel privesc reaching GPU training clusters, and PAN-OS as the beachhead. Living off the LLM, explained.
What a SIEM really costs over three years: Splunk vs Sentinel vs Elastic compared across eight TCO layers, with a 100 GB/day worked example, seven hidden costs, and the RFP questions that expose the real price.
