Sweeps Defender XDR telemetry for known NEBULA / KNTRAT indicators (SHA256 hashes, C2 IP, decoy domain and URLs, burner publisher emails). Hash matching is scoped per table (execution hash only in process events), noisy tooling is excluded from command-line matches, network hits are limited to connection events, and results are aggregated per device and IOC.

IOC sweep for ARTEX campaign indicators: C2 host, nine proxy IPs, xcai.pro and its subdomains, and the CLAUDE.md URL across Defender, CEF/firewall, DNS and Entra sign-in telemetry. Domains match on exact host or subdomain only, connection types are limited to real connection events, and sign-ins are limited to successes and credential failures.

Sweeps endpoint telemetry for known UAC-0099 MATCHBOIL/LONEPAGE indicators: SHA256 hashes, C2 IPs, C2 domains (including subdomains), and payload/C2 URLs. Matches are limited to public outbound connections, Defender self-activity is excluded from file hits, and repeat hits are collapsed to one row per device and indicator. The lists are a subset of the 142 IOCs in the source report.
