Morning Brief — 2026-09-16

2 material breach disclosures, 10 emerging critical cves, 10 supply chain, 32 ransomware activity, 696 ioc volume, 16 active malware families, 3 multi-source iocs, 2 intel feeds, 18 hand-authored sigma, and 18 detection gaps. Sections with no signal are still rendered with an explicit “none in this window” note so absence is visible alongside presence.

Active Malware Families

16 malware families active this week (0 corroborated across ≥2 sources), exercising 19 ATT&CK techniques. Family is the unit, not the indicator: the raw IOCs are drill-down evidence below, not the signal.

Families marked ”→” are delivery/social-engineering clusters (ClickFix, Amadey, GuLoader). Their technique mappings are the delivery chain — downstream behavior is payload-dependent, so they don’t open a hard coverage gap on their own.

Multi-Source IOCs

3 IOCs flagged by 2+ independent sources this window — the highest-confidence signal the cross-feed corpus produces.
