Golden Ticket Detection

detecting-golden-ticket-forgery

mukul975/Anthropic-Cybersecurity-Skills

Detect Kerberos Golden Ticket forgery by analyzing Windows Event IDs 4768/4769 for RC4 downgrades, ticket lifetime violations, and krbtgt anomalies across Splunk or Elastic SIEM, producing risk-scored JSON reports tied to MITRE ATT&CK mapping.

Kerberoasting Detection Guide

detecting-kerberoasting-attacks

mukul975/Anthropic-Cybersecurity-Skills

Documented workflow for hunting Kerberoasting activity by correlating SIEM and EDR telemetry, validating findings, and reporting observations so defenders can proactively detect Credential Access abuse.

Detecting Pass-The-Ticket

detecting-pass-the-ticket-attacks

mukul975/Anthropic-Cybersecurity-Skills

Analyze Windows Event IDs 4768, 4769, and 4771 within Splunk or Elastic SIEM to identify anomalous Kerberos ticket usage, RC4 downgrades, and unusual service requests, enabling proactive Pass-the-Ticket threat detection.

Spearphishing Email Gateway Defense

detecting-spearphishing-with-email-gateway

mukul975/Anthropic-Cybersecurity-Skills

Guides tuning Microsoft Defender for Office 365, Proofpoint, Mimecast, and Barracuda email gateways to detect and block spearphishing by enforcing impersonation guards, URL detonation, attachment sandboxing, and custom detection rules.

Impacket Kerberoasting Guide

exploiting-kerberoasting-with-impacket

mukul975/Anthropic-Cybersecurity-Skills

Detailed walkthrough for using Impacket's GetUserSPNs.py to enumerate service accounts, request Kerberos TGS tickets, export hashes, and crack them offline as part of a Kerberoasting red-team campaign against Active Directory.

Detect C2 Beaconing Patterns

hunting-for-command-and-control-beaconing

mukul975/Anthropic-Cybersecurity-Skills

Detect C2 beaconing patterns by analyzing network telemetry for regular intervals, jitter, and domain reputation to find compromised endpoints communicating with adversary infrastructure before outbreaks escalate.

Attack Path Mapping

implementing-attack-path-analysis-with-xm-cyber

mukul975/Anthropic-Cybersecurity-Skills

Implement XM Cyber's continuous exposure platform to map end-to-end attack paths, highlight choke points, and prioritize the small set of exposures threatening critical business assets for faster risk reduction.

DevSecOps Security Scanning

implementing-devsecops-security-scanning

mukul975/Anthropic-Cybersecurity-Skills

Implement security scanning in CI/CD pipelines across SAST, SCA, container images, and secret detection, using severity-based fail/pass gates with structured JSON outputs for enforcement.

Diamond Model Analysis

implementing-diamond-model-analysis

mukul975/Anthropic-Cybersecurity-Skills

Implements the Diamond Model of Intrusion Analysis in Python, letting you capture adversaries, capabilities, infrastructure, and victims, link events chronologically, surface pivots, and prep MITRE ATT&CK–mapped intelligence for threat teams.

Email Authentication Security Guide

implementing-dmarc-dkim-spf-email-security

mukul975/Anthropic-Cybersecurity-Skills

Guides teams through implementing SPF, DKIM, and DMARC records, validating cryptographic signatures, and parsing DMARC reports so organizations can stop domain spoofing and respond to authentication failures across their email infrastructure.

Zero Trust Identity Verification

implementing-identity-verification-for-zero-trust

mukul975/Anthropic-Cybersecurity-Skills

Guides implementing phishing-resistant MFA and continuous verification in zero trust environments, covering identity infrastructure, conditional access, risk scoring, and identity governance so teams can enforce adaptive, contextual authentication before granting access.

Infrastructure Code Security

implementing-infrastructure-as-code-security-scanning

mukul975/Anthropic-Cybersecurity-Skills

Implements automated IaC security scanning using Checkov, tfsec, and KICS to detect Terraform, CloudFormation, Kubernetes, and Helm misconfigurations, enforce policy-as-code governance, and embed checks in CI/CD pipelines for safe cloud provisioning.
