Email Forwarding Rules Detection

detecting-email-forwarding-rules-attack

mukul975/Anthropic-Cybersecurity-Skills

Hunt for malicious email forwarding rules that adversaries use to maintain persistence, using EDR, SIEM, and telemetry data to validate findings, correlate ATT&CK T1114 indicators, and recommend containment actions.

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.

Insider Threat Detection

detecting-insider-threat-behaviors

mukul975/Anthropic-Cybersecurity-Skills

Detects insider threat behaviors by hunting for unusual data access, privilege abuse, mass downloads, and resignation-linked exfiltration across EDR, SIEM, and intelligence sources to guide incident response actions.

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.

Lateral Movement Detection

detecting-lateral-movement-in-network

mukul975/Anthropic-Cybersecurity-Skills

Analyzes authentication logs, SMB flows, RDP sessions, and Zeek data to spot MITRE ATT&CK lateral movement techniques, powering SIEM alerts, hunting, and post-compromise investigations in enterprise networks.

Mimikatz Execution Detection

detecting-mimikatz-execution-patterns

mukul975/Anthropic-Cybersecurity-Skills

Detect execution patterns of Mimikatz by correlating command-line signatures, LSASS access anomalies, binary indicators, and in-memory modules across EDR and SIEM telemetry, supporting proactive threat hunting and incident response.

Pass The Hash Detection

detecting-pass-the-hash-attacks

mukul975/Anthropic-Cybersecurity-Skills

Detecting Pass-the-Hash attacks by correlating NTLM Type 3 logons, telemetry from EDR/SIEM, and credential-dumping IOCs to proactively hunt and validate incidents across Windows estates.

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.

Privilege Escalation Detection
