Docker Container Hardening

hardening-docker-containers-for-production

mukul975/Anthropic-Cybersecurity-Skills

Guides applying CIS Docker Benchmark best practices across daemon, image, runtime, and host auditing so teams can minimize attack surface, enforce least privilege, and verify secure production deployments.

Docker Daemon Hardening

hardening-docker-daemon-configuration

mukul975/Anthropic-Cybersecurity-Skills

Provides guidelines for hardening the Docker daemon via daemon.json tweaks, user namespace remapping, TLS auth, rootless mode, and CIS benchmark settings to secure container hosts during deployment or assessments.

Linux CIS Benchmark Hardening

hardening-linux-endpoint-with-cis-benchmark

mukul975/Anthropic-Cybersecurity-Skills

Hardens Linux endpoints using CIS Benchmark guidance for Ubuntu, RHEL, and CentOS to enforce security baselines, reduce attack surface, and satisfy compliance requirements during deployments, audits, or remediation efforts.

Secure Windows CIS Hardening

hardening-windows-endpoint-with-cis-benchmark

mukul975/Anthropic-Cybersecurity-Skills

Hardens Windows endpoints using CIS Benchmark guidance to reduce attack surface, enforce security baselines, and stay compliant when commissioning new workstations, servers, or remediating audit findings through GPO deployments and CIS-CAT validation.

Hunt Advanced Persistent Threats

hunting-advanced-persistent-threats

mukul975/Anthropic-Cybersecurity-Skills

Proactively hunt for Advanced Persistent Threats (APTs) by building hypothesis-driven searches across telemetry, network logs, and memory artifacts, using MITRE ATT&CK, Velociraptor, osquery, Zeek, and Sigma-compatible playbooks to validate or rule out known TTPs.

Credential Stuffing Hunting

hunting-credential-stuffing-attacks

mukul975/Anthropic-Cybersecurity-Skills

Detects and investigates credential stuffing by analyzing authentication logs for login velocity anomalies, ASN diversity, password spray behavior, and geographic inconsistencies so SOC teams can build detection rules with Splunk or pandas.

Anomalous PowerShell Hunt

hunting-for-anomalous-powershell-execution

mukul975/Anthropic-Cybersecurity-Skills

Analyzes Script Block Logging (4104), Module Logging (4103), and process creation events in EVTX exports to detect obfuscated PowerShell activity, AMSI bypass attempts, encoded payloads, download cradles, credential dumping, and to prioritize findings for SOC analysts.

Beaconing Frequency Hunting

hunting-for-beaconing-with-frequency-analysis

mukul975/Anthropic-Cybersecurity-Skills

Apply frequency analysis, jitter metrics, and coefficient-of-variation scoring to Zeek/proxy logs and SIEM data to surface periodic C2 beaconing, enrich with threat intelligence, correlate endpoints, and prioritize high-risk callbacks during threat hunting.

Detect Cobalt Strike Beacons

hunting-for-cobalt-strike-beacons

mukul975/Anthropic-Cybersecurity-Skills

Detect Cobalt Strike beacon callbacks by correlating TLS certificate signatures, JA3/JA3S/JARM fingerprints, HTTP C2 profile matches, beacon interval jitter, and Zeek/Suricata/Python PCAP analysis to flag high-confidence activity and suggest responses.

Command and Control Beaconing Detection

hunting-for-command-and-control-beaconing

mukul975/Anthropic-Cybersecurity-Skills

Detects command-and-control beaconing in network telemetry via frequency/jitter analysis, reputation checks, and endpoint context so hunters can spotlight compromised hosts and guide response workflows.

Defense Evasion Timestomping

hunting-for-defense-evasion-via-timestomping

mukul975/Anthropic-Cybersecurity-Skills

Detects NTFS timestomping (MITRE T1070.006) by comparing $STANDARD_INFORMATION and $FILE_NAME timestamps from analyzeMFT/MFTECmd output, enabling threat hunters to flag anomalous temporal edits in forensic timelines.

DNS Persistence Hunting Guide

hunting-for-dns-based-persistence

mukul975/Anthropic-Cybersecurity-Skills

Step-by-step skill to hunt DNS-based persistence by auditing zone baselines, querying SecurityTrails passive DNS, analyzing provider audit logs, and correlating anomalies to malicious infrastructure for actionable reports.
