Recent OSINT Events

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

Active Malware Families

14 malware families active this week (0 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

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.

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 (8,767 indicators total) — each available as CSV, MISP JSON, and STIX 2.1. Subscribe at https://thrunt.me/intel/manifest.json.

Hand-Authored Sigma
