Introduction:
Offensive AI agents built on large language models (LLMs) inherit a critical weakness: their training data is overwhelmingly sourced from public capture-the-flag (CTF) platforms like HackTheBox, TryHackMe, and VulnHub. This creates a predictable bias toward known attack paths, meaning enterprises that deploy strategic deception—honeypots, honey tokens, and canary traps—can trigger early detection and containment before any real damage occurs.
Learning Objectives:
- Understand how LLM training data bias limits autonomous offensive AI agents and creates exploitable predictability.
- Implement deception infrastructure (honeypots, honey tokens, decoy services) to misdirect and detect AI-driven attacks.
- Apply Linux and Windows commands to deploy, monitor, and automate deception-based defenses against agentic threats.
You Should Know
1. Mapping Attack Paths to Deceive AI Agents
LLM-based agents are trained to follow “typical” attack chains: reconnaissance → vulnerability scanning → credential dumping → privilege escalation → lateral movement → data exfiltration. By mapping your own crown jewels and likely initial access vectors, you can place decoys along these predictable paths.
Step‑by‑step guide:
- Identify likely entry points – Public-facing services (web, SSH, RDP, VPN).
- Map internal choke points – Where attackers must go to reach sensitive data (domain controllers, backup servers, database hosts).
- Place decoys at each stage – A fake SSH honeypot on the perimeter, a mock file share with honey tokens, a simulated database with fake credentials.
Linux command to create a low-interaction SSH honeypot (using endlessh):
Install endlessh (SSH tarpit) sudo apt update && sudo apt install endlessh -y Configure to listen on port 22 sudo nano /etc/endlessh/config Add: Port 22 Delay 1000 MaxLineLength 32 MaxClients 1024 sudo systemctl enable endlessh && sudo systemctl start endlessh
Windows PowerShell command to create a fake SMB share (honeypot):
Create a decoy share that logs all access New-Item -Path "C:\DecoyShare" -ItemType Directory New-SmbShare -Name "PublicData" -Path "C:\DecoyShare" -FullAccess "Everyone" Enable auditing for the share Set-SmbServerConfiguration -AuditSmb1Access $true -AuditSmb2Access $true
2. Deploying Low-Interaction Honeypots on Linux and Windows
Low-interaction honeypots mimic services without full OS emulation, perfect for catching AI agents that blindly scan for common weaknesses.
Linux – T-Pot (multi-honeypot platform):
Install Docker and T-Pot (requires >=8GB RAM) curl -sSL https://get.docker.com | sh sudo systemctl enable docker && sudo systemctl start docker git clone https://github.com/telekom-security/tpotce cd tpotce && sudo ./install.sh --type=user Access web UI on port 64297
Windows – Deploy a fake SMB/CIFS service using `honeyd` (via WSL or Python):
fake_smb.py – simple SMB honeypot using impacket
from impacket.smbserver import SMBSERVER
import logging
logging.basicConfig(level=logging.INFO)
server = SMBSERVER(("0.0.0.0", 445))
server.processConfigFile('smb.conf') Minimal config
server.serve_forever()
How to use: Run the script on a low-privilege VM. Every connection attempt gets logged with source IP, protocol version, and attempted shares. AI agents attempting `smbclient` or `enum4linux` will trigger an alert.
3. Honey Tokens: Generating Fake Credentials and Data
Honey tokens are fake credentials, API keys, or database entries that no legitimate user would ever touch. When an AI agent uses them, you get an immediate high-fidelity alert.
Generate fake cloud API keys (AWS-style):
Create a file with realistic but fake keys
cat > /var/www/html/config.php << 'EOF'
<?php
// Decoy keys – monitor any usage
define('AWS_ACCESS_KEY', 'AKIAFAKEFAKE12345678');
define('AWS_SECRET_KEY', 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY');
define('DB_PASSWORD', 'DecoyDbPass_2025!');
?>
EOF
Windows – Honey registry token:
Create a fake service credential in registry (monitor reads)
New-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\HoneyTokens" -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\HoneyTokens" -Name "BackupCreds" -Value "ServiceAccount:svc_backup:D3c0y!Pass" -PropertyType String
Enable SACL to log reads
$acl = Get-Acl "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\HoneyTokens"
$rule = New-Object System.Security.AccessControl.RegistryAuditRule("Everyone", "ReadKey", "Success", "None", "Audit")
$acl.AddAuditRule($rule)
Set-Acl "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\HoneyTokens" $acl
Monitoring: Set up a SIEM alert (e.g., Splunk, Wazuh) for any process accessing these files or registry keys. AI agents crawling for secrets will trigger instantly.
- Detecting AI Agent Recon Activity with Log Analysis
LLM-based agents often exhibit rapid, scanner-like behavior. They enumerate directories, run common tools (nmap, gobuster, ffuf), and follow deterministic patterns that differ from human attackers.
Linux – Detect mass directory scans with `fail2ban` custom filter:
Custom regex for AI-like rapid scanning sudo nano /etc/fail2ban/filter.d/ai-scan.conf Content: [bash] failregex = ^<HOST> . "GET /(wp-admin|phpmyadmin|backup|.env|.git) . 404 ignoreregex = sudo systemctl restart fail2ban
Windows – Monitor for PowerShell-based recon:
Get events for repeated network connections from same source
$log = Get-WinEvent -FilterHashtable @{LogName='Microsoft-Windows-Sysmon/Operational'; ID=3} -MaxEvents 1000
$grouped = $log | Group-Object { $<em>.Properties[bash].Value } | Where-Object { $</em>.Count -gt 50 }
$grouped | Export-Csv -Path "ai_recon_log.csv" -NoTypeInformation
Step‑by‑step: Deploy Sysmon on Windows, forward events to a centralized log server (e.g., Elastic Stack). Set up a threshold alert: if a single source IP makes >100 connection attempts to distinct ports or HTTP paths within 60 seconds, automatically trigger a honeypot redirect.
5. Baiting LLM Agents with Canary Traps
Canary traps (e.g., Thinkst Canary, OpenCanary) automatically deploy decoy services that look like real infrastructure. When an AI agent touches them, you get an alert with full attacker forensics.
Deploy OpenCanary on Linux:
Install OpenCanary sudo apt install python3-pip -y git clone https://github.com/thinkst/opencanary cd opencanary sudo pip3 install . Generate config opencanaryd --copyconfig sudo nano /etc/opencanaryd/opencanary.conf Enable modules: smb, http, ssh, mysql, redis sudo systemctl enable opencanaryd && sudo systemctl start opencanaryd
Windows – Simulate a vulnerable RDP service using rdp-simulator:
Using Chocolatey to install a Python-based RDP honeypot choco install python -y pip install pyrdp Run a fake RDP listener that logs all credentials pyrdp-mitm.py --port 3389 --log-file "c:\honey\rdp_log.txt" --target 127.0.0.1:3388
How LLM agents get tricked: An agent scanning for open RDP will connect to the simulator. Since the agent’s training data includes “RDP brute-force → log in → execute commands,” it will attempt default credentials. The simulator logs the attempt and can even return a fake desktop environment, wasting the attacker’s time while you get alerted.
6. Automating Deception Response with SOAR
Once a decoy is triggered, you need immediate action to contain the threat. Use Security Orchestration, Automation, and Response (SOAR) tools to block the attacker IP, isolate the compromised decoy, and spin up fresh honeypots.
Example using TheHive + Cortex (open source SOAR):
Cortex analyzer to block IP on firewall (pseudo-code)
import requests
def block_ip(ip_address):
Block via iptables on Linux
subprocess.run(f"iptables -A INPUT -s {ip_address} -j DROP", shell=True)
Block via PowerShell on Windows Firewall
subprocess.run(f'powershell New-NetFirewallRule -DisplayName "Block {ip_address}" -Direction Inbound -RemoteAddress {ip_address} -Action Block', shell=True)
Send alert to SIEM
requests.post("https://your-siem/api/alert", json={"source_ip": ip_address, "action": "blocked"})
Step‑by‑step:
- Configure OpenCanary to send alerts to a webhook (Slack, Teams, or Cortex).
- Create a playbook that extracts the attacker’s source IP.
- Automatically add the IP to your firewall’s deny list (iptables, AWS Security Group, or Azure NSG).
- Log the event to your SIEM and increment a deception counter.

Testing Your Own Defenses with Simulated AI Agents
The best way to validate your deception strategy is to use the same LLM-based agents your adversaries might deploy. Open-source agentic frameworks like AutoGPT, PentestGPT, or ReconAIzer can simulate autonomous attacks.
Run PentestGPT against a decoy environment:
Install PentestGPT git clone https://github.com/GreyDGL/PentestGPT cd PentestGPT pip3 install -r requirements.txt export OPENAI_API_KEY="your-key" python3 pentestgpt.py -t http://your-honeypot-ip:8080
Expected outcome: The agent will discover your decoy web service, attempt common exploits (SQLi, LFI, path traversal), and try to escalate privileges. Your deception infrastructure should fire alerts immediately. If the agent bypasses your decoys undetected, you have identified gaps.
Windows – Simulate AI agent behavior with PowerShell:
Automated recon script mimicking an LLM agent
$targets = @("192.168.1.1", "192.168.1.100")
foreach ($ip in $targets) {
Test-NetConnection $ip -Port 22
Test-NetConnection $ip -Port 445
Invoke-WebRequest -Uri "http://$ip/.env" -ErrorAction SilentlyContinue
Invoke-WebRequest -Uri "http://$ip/backup.zip" -ErrorAction SilentlyContinue
}

What Undercode Say:
- Key Takeaway 1: LLM-based offensive AI agents are not superhuman—they are pattern-matching engines. Their reliance on CTF training data makes them predictable and vulnerable to well-placed deception. Enterprises that deploy honey tokens, canary traps, and low-interaction honeypots along common attack paths can reliably detect and block these agents before any breach occurs.
-
Key Takeaway 2: The real threat is not fully autonomous agents but human attackers using LLMs as force multipliers. Deception alone won’t stop a skilled adversary with human judgment, but it raises their cost and forces them to spend time validating fake leads. Combined with traditional defense-in-depth (patching, EDR, zero trust), deception creates an asymmetric advantage that turns an AI agent’s strength—speed—into its own weakness by generating noisy, detectable signals.
The research paper from USENIX Security ’25 (Ayzenshteyn et al.) confirms that LLM bias is exploitable at scale. Offensive agents trained on CTFs consistently fall for the same deception lures because their models learn that “real” attack paths look like those in training. This is analogous to model poisoning but on the input side: defenders can inject decoys that resemble training environments, causing agents to waste cycles on dead ends. The key is to map your network’s unique layout, then deploy decoys that mimic the CTF-style flags and services these agents expect. When the agent “captures” a fake flag, you get a perfect alert—no false positives, no noisy logs, just a direct signal that an AI is inside your deception net. Organizations that fail to adopt active defense will continue to be pwned by commodity attacks, AI-powered or not.
Prediction:
As LLM-based offensive agents become commoditized (via open-source frameworks and AI-as-a-service), deception will evolve from a niche tactic into a core enterprise security control. By 2027, we expect “deception-as-a-service” platforms that auto-generate dynamic honeypots, honey tokens, and fake network topologies tailored to each organization’s exposed assets. SIEMs and SOARs will incorporate LLM-bias detection models that not only spot agentic behavior but also adapt decoys in real time based on the agent’s observed actions. The arms race will shift from finding vulnerabilities to poisoning training data at scale—defenders will flood public CTF platforms with fake flags and decoy exploits, contaminating the very datasets that future offensive AI agents rely on. Meanwhile, nation-state actors will invest in custom-trained agents that use reinforcement learning on proprietary red-team data to overcome these biases. The enterprises that survive will be those that combine deception with human-led threat hunting, treating AI agents as fast, dumb adversaries rather than unstoppable terminators.
