Introduction:
A legitimate New Orleans City Council government website was discovered promoting “Top 8 AI Porn Platforms Ranked and Reviewed in 2026,” redirecting citizens to explicit adult content generated by artificial intelligence. This incident highlights the growing risk of website defacement and malicious redirection, where attackers exploit weak content management systems (CMS), exposed APIs, or compromised third-party integrations to inject unauthorized links into trusted domains, damaging public trust and exposing visitors to inappropriate or malicious material.
Learning Objectives:
- Identify common web application vulnerabilities that allow attackers to inject unauthorized content into government portals.
- Perform forensic analysis of website source code and HTTP response headers to detect malicious redirects and hidden links.
- Implement secure CMS hardening, file integrity monitoring, and API security controls to prevent similar compromises.
You Should Know:
- Detecting Hidden Malicious Links and Redirects in Government Websites
This step-by-step guide replicates the discovery process used by security researchers to find unauthorized content on a live website.
What happened: An attacker gained write access to the council’s web server (possibly via stolen credentials, an unpatched CMS plugin, or misconfigured cloud storage) and injected a block of HTML containing affiliate links to AI porn platforms. The link “SWBNO-Customer-Appeals” was a disguised path pointing to `https://lnkd.in/euQwkqAE` (a LinkedIn shortener that may lead to adult content). The main index page was altered to show the promotional text.
Step‑by‑step discovery and analysis (Linux/macOS):
1. Fetch the website’s raw HTML and search for suspicious patterns curl -s https://council.nola.gov | grep -iE "(porn|adult|ai.video|explicit)" -C 3 <ol> <li>Extract all links from the page and check redirections curl -s https://council.nola.gov | grep -oE 'href="[^"]+"' | cut -d'"' -f2 | while read url; do echo "[] Checking $url" curl -sI "$url" | grep -i "location:" done</p></li> <li><p>Recursively crawl for hidden directories (wordlist-based) gobuster dir -u https://council.nola.gov -w /usr/share/wordlists/dirb/common.txt -x .html,.php</p></li> <li><p>Check DNS records for anomalies (possible subdomain takeover) dig council.nola.gov A dig council.nola.gov CNAME</p></li> <li><p>Use browser dev tools to inspect DOM after JavaScript execution Manually open browser > F12 > Network tab > Reload, search for "lnkd.in" or "SWBNO"
Windows equivalent (PowerShell):
Fetch page and search for malicious patterns
Invoke-WebRequest -Uri "https://council.nola.gov" | Select-Object -ExpandProperty Content | Select-String -Pattern "porn|adult|explicit"
Check link redirections
$links = (Invoke-WebRequest -Uri "https://council.nola.gov").Links.href
foreach ($link in $links) {
try { (Invoke-WebRequest -Uri $link -Method Head -MaximumRedirection 0).StatusCode }
catch { Write-Host "Redirect from $link" }
}
What to look for: Unexpected `href` attributes pointing to shorteners (lnkd.in, bit.ly), adult keywords embedded in `title` or `meta` tags, or JavaScript that dynamically injects content only for certain user agents.
- Hardening Content Management Systems (CMS) Against Injection Attacks
Most government websites run on CMS platforms like WordPress, Drupal, or Joomla. This guide assumes a common LAMP stack.
Step‑by‑step hardening:
Linux: Set strict file permissions for web root (e.g., /var/www/html)
sudo find /var/www/html -type f -exec chmod 644 {} \;
sudo find /var/www/html -type d -exec chmod 755 {} \;
sudo chown -R www-data:www-data /var/www/html
sudo chmod 440 /var/www/html/wp-config.php Protect config file
Disable directory browsing
echo "Options -Indexes" | sudo tee -a /var/www/html/.htaccess
Enable automated file integrity monitoring (AIDE)
sudo apt install aide -y
sudo aideinit
sudo mv /var/lib/aide/aide.db.new /var/lib/aide/aide.db
Run daily check
sudo aide --check | grep -E "changed|added|removed" | mail -s "AIDE Alert" [email protected]
Block unauthorized outbound connections from web server (prevent callbacks)
sudo iptables -A OUTPUT -p tcp --dport 80 -m owner --uid-owner www-data -j REJECT
sudo iptables -A OUTPUT -p tcp --dport 443 -m owner --uid-owner www-data -j REJECT
Windows IIS hardening (PowerShell as Admin):
Remove unnecessary IIS features
Remove-WindowsFeature Web-DAV-Publishing, Web-Mgmt-Console
Disable directory browsing
Set-WebConfigurationProperty -Filter "system.webServer/directoryBrowse" -Name "enabled" -Value $false
Enable request filtering to block malicious patterns
Add-WebConfigurationProperty -Filter "system.webServer/security/requestFiltering" -Name "denyUrlSequences" -Value @{string="porn"; string="adult"; string="explicit"}
Set up file change auditing
auditpol /set /subcategory:"File System" /success:enable /failure:enable
- API Security: Preventing Malicious Content Injection via Third‑Party Integrations
Attackers often abuse exposed APIs to update website content. This step covers securing REST APIs used by government portals.
Common vulnerability: Unauthenticated POST/PUT endpoints that allow HTML injection.
Testing for API misconfigurations (using curl and Burp Suite):
Test if API allows arbitrary content update without auth
curl -X PUT https://council.nola.gov/api/content/home \
-H "Content-Type: application/json" \
-d '{"body": "
Promoting AI porn
"}'
Check for CORS misconfigurations
curl -H "Origin: https://evil.com" -H "Access-Control-Request-Method: PUT" \
-X OPTIONS https://council.nola.gov/api/content -v
Enumerate API endpoints from JavaScript files
curl -s https://council.nola.gov | grep -oE 'src="[^"]+.js"' | cut -d'"' -f2 | while read js; do
curl -s "$js" | grep -oE '/api/[a-zA-Z0-9/]+'
done
Mitigation (Node.js/Express example):
// Implement input validation and sanitization
const express = require('express');
const helmet = require('helmet');
const xss = require('xss');
app.use(helmet()); // Sets security headers
app.post('/api/update', (req, res) => {
let cleanBody = xss(req.body.content); // Strip HTML/JS
if (cleanBody.match(/(porn|adult|explicit)/i)) {
return res.status(403).json({ error: 'Content blocked' });
}
// Proceed with update after strict authentication
});
4. Cloud Hardening for S3‑Hosted Static Government Sites
Many municipalities host static sites on AWS S3. Misconfigured bucket policies can allow unauthorized file writes or public listing.
Step‑by‑step audit (AWS CLI):
List all S3 buckets in the account
aws s3 ls
Check bucket ACLs and public access
aws s3api get-bucket-acl --bucket council.nola.gov
aws s3api get-bucket-policy-status --bucket council.nola.gov
Enable default encryption and block public access
aws s3api put-bucket-encryption --bucket council.nola.gov \
--server-side-encryption-configuration '{"Rules":[{"ApplyServerSideEncryptionByDefault":{"SSEAlgorithm":"AES256"}}]}'
aws s3api put-public-access-block --bucket council.nola.gov \
--public-access-block-configuration BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true
Enable versioning to recover from malicious overwrites
aws s3api put-bucket-versioning --bucket council.nola.gov --versioning-configuration Status=Enabled
If the bucket is compromised, restore previous version:
List versions of the compromised file (e.g., index.html) aws s3api list-object-versions --bucket council.nola.gov --prefix index.html Roll back to clean version ID aws s3api copy-object --bucket council.nola.gov --copy-source "council.nola.gov/index.html?versionId=<CLEAN_VERSION>" --key index.html
- Vulnerability Exploitation & Mitigation: Cross‑Site Scripting (XSS) for Content Injection
The “AI porn” promotion could be injected via an XSS vulnerability on a government comment form or search bar.
Proof of concept (for authorized testing only):
<!-- Inject into vulnerable input field --> <script>document.body.innerHTML += '<a href="https://lnkd.in/euQwkqAE">SWBNO-Customer-Appeals</a>';</script>
Mitigation – Content Security Policy (CSP) headers:
In Apache virtual host or .htaccess Header set Content-Security-Policy "default-src 'self'; script-src 'self' https://cdn.nola.gov; connect-src 'none'; frame-ancestors 'none'; base-uri 'self'; form-action 'self'"
Testing CSP effectiveness (curl):
curl -sI https://council.nola.gov | grep -i "content-security-policy"
- Proactive Monitoring Using Open Source Tools (Wazuh / OSSEC)
Deploy file integrity monitoring (FIM) on government web servers to detect unauthorized changes.
Install Wazuh agent on Linux:
curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | sudo apt-key add - echo "deb https://packages.wazuh.com/4.x/apt/ stable main" | sudo tee /etc/apt/sources.list.d/wazuh.list sudo apt update && sudo apt install wazuh-agent sudo systemctl enable wazuh-agent --now
Configure FIM for web root:
<!-- Edit /var/ossec/etc/ossec.conf --> <syscheck> <directories check_all="yes" realtime="yes">/var/www/html</directories> <ignore type="sregex">.log$|.cache$</ignore> </syscheck>
Send alerts to SIEM – example rule to detect adult keywords:
<rule id="100100" level="12"> <if_sid>550</if_sid> <match>porn|adult|explicit|AI.video</match> <description>Unauthorized adult content detected in web file</description> </rule>
What Undercode Say:
- Key Takeaway 1: Government websites are prime targets for SEO poisoning and brand defacement because of their high domain authority. Attackers inject hidden links or visible promotions to boost ranking for illicit terms like “AI porn” – a low‑cost, high‑impact attack that can go unnoticed for days.
- Key Takeaway 2: The exploitation vector likely involved a compromised administrator account or an outdated plugin with remote file inclusion (RFI). The use of a LinkedIn shortener (
lnkd.in) suggests the attacker wanted to bypass URL filters and gain click analytics. Immediate response must include revoking all sessions, rotating secrets, and scanning for backdoors.
Analysis: This incident is not an isolated prank. It reflects a broader trend where AI‑generated adult content is being used as bait for malware distribution or affiliate fraud. The fact that a `.gov` domain was hosting such links undermines public trust and violates federal security guidelines (e.g., NIST SP 800‑53). Municipal IT teams often lack dedicated web security budgets, making them soft targets. Organizations must adopt DevSecOps principles for their public‑facing portals, including automated vulnerability scanning (OWASP ZAP), WAF rules to block adult keywords, and regular content integrity audits. The post by Henk G. serves as a critical wake‑up call for any organization that assumes “it won’t happen to us.”
Prediction:
Within the next 12 months, we will see a surge in AI‑powered social engineering campaigns that automatically scan for vulnerable government subdomains, inject deepfake promotional content, and use generative AI to craft convincing landing pages. Municipalities that fail to implement zero‑trust web publishing – where every content change requires cryptographic signing and real‑time anomaly detection – will repeatedly face similar PR disasters. Attackers will increasingly weaponize legitimate link shorteners and CDNs to evade detection, forcing security teams to adopt AI‑driven content classification at the edge. The New Orleans incident will be cited in future CISA advisories as a case study for “unacceptable content injection.”
