Microsoft Exchange Zero-Day:
One Email Hijacks Your Session

A crafted email executes JavaScript inside an authenticated OWA session. No credentials required. No permanent patch. CISA KEV — federal deadline May 29. Exchange Online is not affected.

Standard user in, SYSTEM shell out. Public exploit on GitHub. No patch until June 10. The 6th zero-day in 6 weeks from the same rogue researcher — first 3 were used in real attacks.

No race condition. Public PoC. Container escape. The Dirty Frag kernel patch alone does NOT protect you — a separate patch is required. Third Linux root exploit in two weeks.

Four DTLS packets. No credentials. Full administrative access to the entire enterprise SD-WAN fabric. CISA Emergency Directive. Active exploitation confirmed.

VulnCheck confirms real-world attacks days after public disclosure. CVSS 9.2. ~34% of all internet web servers running a vulnerable version. Patch to NGINX 1.30.1 immediately.

One malformed SMTP sequence corrupts the heap and opens a shell. An autonomous AI built the full exploit in 7 days. Patch to Exim 4.99.3 immediately.

732 bytes of Python. Root on every major Linux distro since 2017. No race condition. No disk trace. Container escape. CISA KEV listed.

Fake developer packages stealing SSH keys, AWS credentials, and GitHub tokens the moment they were installed. Sleeper packages deployed first, then updated to malicious.

Hardcoded credentials and exposed API keys are a silent epidemic. Most teams don’t discover them until it’s too late.

A zero-day gives attackers a window defenders can’t close in time. Here’s how enterprises reduce damage before patches exist.

Most organizations discover their IR plan is broken only when they need it most. Don’t be one of them.

Alert fatigue, talent shortages, and attacker velocity are breaking the classic SOC model. AI-driven ops are no longer optional.
