Morning Brief — 2026-08-02

4 material breach disclosures, 10 emerging critical cves, 14 ransomware activity, 809 ioc volume, 12 active malware families, 11 multi-source iocs, 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

14 new victim postings across 7 groups.

IOC Volume

809 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

12 malware families active this week (1 corroborated across ≥2 sources), exercising 17 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

11 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.

Cross-Reference

No SEC × KEV vendor token matches in this window. (This is a heuristic surface, absence is expected most days.)

Intel Feeds

4 IOC feeds updated this run (8,913 indicators total) — each available as CSV, MISP JSON, and STIX 2.1. Subscribe at https://thrunt.me/intel/manifest.json.

Hand-Authored Sigma

3 production-ready TTP rules (+2 scaffolds in the authoring queue) live at https://thrunt.me/sigma/manifest.json. Subscribe via https://thrunt.me/sigma/rules.lock.json (content-hash churn) or pull all with https://thrunt.me/sigma/rules.tar.gz.

Detection Gaps

17 of 157 techniques with corpus signal have zero detection coverage — no SigmaHQ community rule, no thrunt rule. This is the hand-authoring queue; the live view is at https://thrunt.me/corpus/attck/.
