Discovering & Disrupting Malicious Infrastructure

Hunt introduces Advanced Search, a query language for malware, certificates and open-directory files, shown via Quasar RAT hunts, Cobalt Strike certificate pivots and JA4X-based Sliver discovery.

Hunt tracked Geacon_Pro, a Golang Cobalt Strike implementation, via its default 'foren.zik' TLS certificate, surfacing servers and open directories used against Linux and Windows hosts.

Hunt explains how it identifies, tracks and 'burns' malicious C2 servers using TLS certificates, HTTP headers, SSH keys, JARM/JA4x hashes and TCP banners, seen in Gh0st and ShadowPad cases.

A step-by-step infrastructure hunting walkthrough: from an AsyncRAT-linked IP, pivoting through ASN data, ports, services and TLS certificates to uncover a wider cluster of systems.

Part 4 of the Cobalt Strike series: automating the C2 feed via API—normalizing indicators into core, network and endpoint outputs for SIEM, IDS/EDR and sandbox pipelines.

Part 3 of the Cobalt Strike series: the C2 dashboard automates discovery—certificate matching, header analysis and protocol inspection track 800–1,000 active servers with 90% validation confidence.
