Bulletproof Hosting: Map Criminal Infrastructure
Identify bulletproof hosting through ASN, prefix, domain, abuse, migration, and campaign signals without treating an entire network as malicious.
Domain Shadowing: Detect Compromised DNS at Scale
Detect domain shadowing by monitoring DNS changes, certificate issuance, subdomain behavior, account security, and infrastructure relationships.
DGA Detection: Find Algorithmically Generated Domains
Detect domain generation algorithms with lexical, DNS, endpoint, and reputation signals while controlling false positives in production.
Fast-Flux DNS: Detect Rotating Attack Infrastructure
Learn how to detect fast-flux DNS using TTL, passive DNS, ASN diversity, reputation signals, and a repeatable SOC investigation workflow.
Malicious Infrastructure Clustering: How Passive DNS, TLS Certificates, and ASNs Reveal Shared Campaigns
A single C2 IP is a clue; shared signing patterns and DNS co-occurrence are a map. This guide explains how defenders cluster infrastructure without chasing ghosts—and how to document findings for IR, threat intel, and law enforcement handoffs.
