Morning Brief — 2026-08-09

4 material breach disclosures, 1 exploit probability movers, 10 emerging critical cves, 11 ransomware activity, 1810 ioc volume, 15 active malware families, 25 multi-source iocs, 1 cross-reference, 4 intel feeds, 5 hand-authored sigma, and 17 detection gaps. Sections with no signal are still rendered with an explicit “none in this window” note so absence is visible alongside presence.

Supply Chain

No high/critical GHSA advisories in this window.

Ransomware Activity

11 new victim postings across 6 groups.

IOC Volume

1810 new IOCs in this window. By source:

Recent OSINT Events

No curated MISP events in this window (bulk-IOC contributions tallied in IOC Volume).

Active Malware Families

15 malware families active this week (1 corroborated across ≥2 sources), exercising 14 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). 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

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

MISP × KEV Correlation

No MISP events in this window referenced a CVE.
