Deploy a Velociraptor server and agents, then author VQL (Velociraptor Query Language) artifacts and run them as fleet-wide hunts, on-demand forensic collections, or standalone offline collectors. Use when hunting a TTP across hundreds or thousands of endpoints, collecting forensic artifacts during incident response without re-imaging, or generating collectors for unmanaged/air-gapped hosts.

Generate CycloneDX and SPDX SBOMs from container images and filesystems with Syft, correlate them to CVEs with Grype, and sign/attest them with Cosign. Use when you need a machine-readable dependency inventory for supply-chain risk, want to scan images or SBOMs for known vulnerabilities, or are embedding SBOM generation and vulnerability gating into CI/CD.

Run Hayabusa against collected Windows EVTX files to apply Sigma detection rules and produce a prioritized, chronological CSV/JSON timeline with severity levels, MITRE ATT&CK mappings, and per-host/per-Event-ID metrics. Use during DFIR triage to turn raw event logs into a fast, SIEM-free incident timeline, or to export results into Timesketch or Timeline Explorer for collaborative analysis.

'Detects credential stuffing attacks by analyzing authentication logs

Run Chainsaw against collected Windows EVTX files to hunt with the SigmaHQ rule corpus, built-in detection rules, and high-speed keyword/regex search, plus analyze shimcache, SRUM, and event-log gaps, outputting colorized tables, CSV, or JSON. Use during first-response triage for offline, SIEM-free detection over Windows event logs, or to quickly confirm a hunt hypothesis and produce reporting output.

'Hunt for malicious PowerShell activity by analyzing Script Block Logging

Identify command-and-control beaconing patterns in network traffic by

Detect Cobalt Strike beacon command-and-control traffic using default TLS certificate signatures (serial 8BB00EE), JA3/JA3S/JARM fingerprints, HTTP malleable C2 profile pattern matching, and beacon jitter/interval analysis, built with Zeek network logs, Suricata IDS rules, and Python PCAP analysis. Use when hunting for Cobalt Strike beacon callbacks in network traffic or building detection rules for this C2 framework.

Detect C2 beaconing patterns in network traffic using frequency analysis,

Hunt for data exfiltration by analyzing Zeek and Suricata network telemetry for unusual data flows, DNS tunneling via large/frequent TXT queries, uploads to personal cloud storage, and encrypted-channel abuse, correlated against threat intel on destination domains. Use when hunting for data theft in a compromised environment, investigating unusual outbound data volumes, or determining what data was stolen during incident response.

Detect data-staging activity (MITRE ATT&CK T1074) by analyzing EDR/Sysmon process-creation and file-system telemetry (Event ID 4688, Sysmon 1/11) for 7-Zip/RAR/tar archive creation, unusual temp or hidden folder access, and anomalous consolidation of files from multiple directories. Use when hunting for pre-exfiltration staging behavior, building detection rules for archiver abuse, or validating monitoring coverage for T1074.

'Hunt for DCOM-based lateral movement (MITRE ATT&CK T1021.003) by detecting

Detect DCSync attacks (MITRE ATT&CK T1003.006) by analyzing Windows Event ID 4662 (AccessMask 0x100) for DS-Replication-Get-Changes and DS-Replication-Get-Changes-All requests issued by non-domain-controller accounts. Use when hunting for DCSync credential theft, after detecting Mimikatz-class tooling, or during incident response and purple-team exercises involving Active Directory replication abuse.

Runs a hypothesis-driven threat hunt for Windows Scheduled Task persistence (T1053), guiding SIEM/EDR queries against task creation events (e.g. Event ID 4698), suspicious task actions, and unusual scheduling patterns. Use when hunting for scheduled-task persistence, after threat intel flags related campaigns, during incident response, or when alerts fire on schtasks/at.exe activity.

Runs a hypothesis-driven threat hunt for Volume Shadow Copy deletion (T1490) by querying SIEM/EDR telemetry for vssadmin, wmic shadowcopy, and PowerShell shadow-copy-deletion commands.
