What happened
The Rapid7 corpus for early April 2026 highlights several high-impact security developments: Anthropic’s Project Glasswing (Claude Mythos Preview) is surfacing and in some cases autonomously developing exploits for thousands of high‑severity vulnerabilities, signaling faster discovery and greater pressure on prioritization and remediation workflows. Rapid7 Incident Response documented active exploitation of FortiGate SSO signature‑verification flaws (CVE‑2025‑59718 and related CVE‑2025‑59719), showing initial low‑profile compromise of appliances followed by lateral movement into internal hosts
