What happened
Multiple high-impact incidents reported: Microsoft confirmed a RoguePlanet zero-day in Microsoft Defender (CVE-2026-50656, privilege escalation, CVSS 7.8) and is developing a patch. A mass credential exposure (“FortiBleed”) leaked plaintext admin VPN credentials for ~75,000 Fortinet devices. DragonForce operators routed C2 through Microsoft Teams to evade detection for weeks. CISA added a critical Joomla Widget Factory (JCE) flaw (CVE-2026-48907, CVSS 10.0) to its KEV catalog. Additional notable items include the Rokarolla Android banking trojan targeting 217 apps, FulcrumSec’s 1.3TB data leak
