AI Deepfakes & Global Scam Networks: Why Malwarebytes Joined GASA To Fight Social Engineering At Scale + Video

Introduction:

The Global Anti-Scam Summit Europe 2026, held in Lisbon under the theme “Europe Against Scams: Public Private Partnerships in Action,” underscored a harsh reality: online scams have evolved into AI-driven, deepfake-laced, highly targeted operations that no single organization can defeat alone. Malwarebytes’ decision to join the Global Anti-Scam Alliance (GASA) as a supporting member signals a critical shift—toward real‑time intelligence sharing, cross‑sector collaboration, and technical countermeasures that blend threat hunting, behavioural analytics, and infrastructure disruption.

Learning Objectives:

Identify how AI‑generated deepfakes and social engineering tactics bypass traditional security controls.
Implement Linux and Windows forensic commands to trace scam infrastructure and extract malicious URLs.
Apply cloud hardening and API security techniques to disrupt scam‑as‑a‑service platforms.

You Should Know:

1. Real‑time Deepfake Detection Using Open‑Source Tools

Deepfakes are now used in vishing (voice phishing) and video impersonation. Before trusting any audiovisual content, use command‑line forensic tools to analyse metadata and inconsistencies.

Step‑by‑step guide (Linux):

Install `ffmpeg` and `mediainfo` to inspect video streams:

sudo apt install ffmpeg mediainfo -y
mediainfo suspicious_video.mp4 | grep -E "Frame rate|Codec|Bit rate"

Extract frames every second and look for unnatural blinking or lip‑sync errors:
```
ffmpeg -i suspicious_video.mp4 -vf fps=1 frame_%04d.png
```

Use `deepface` (Python) to compare facial landmarks against known genuine samples:

pip install deepface
python -c "from deepface import DeepFace; result = DeepFace.verify(img1_path='frame_0001.png', img2_path='known_face.jpg'); print(result)"

Windows alternative:

Download `ExifTool` and run:

exiftool suspicious_video.mp4 | findstr "Create Date Software"

Use `ffmpeg` for Windows similarly via WSL or native build.

Tracing Scam Infrastructure with OSINT and DNS Enumeration

Scam networks often rotate domains and IPs. Use passive DNS and WHOIS to map their footprint.

Step‑by‑step guide (Linux/macOS):

Perform reverse DNS lookup on a suspicious IP:
```
dig -x 185.130.5.253 +short
```

Enumerate subdomains of a known scam domain using dnsrecon:

dnsrecon -d scam-bank[.]xyz -D /usr/share/wordlists/subdomains.txt -t brt

Check SSL certificate history with crt.sh:

curl -s "https://crt.sh/?q=%25.scam-bank.xyz&output=json" | jq '.[].name_value'

Windows (PowerShell):

Resolve-DnsName -1ame scam-bank.xyz -Type A
 Query crt.sh via Invoke-RestMethod
Invoke-RestMethod -Uri "https://crt.sh/?q=%25.scam-bank.xyz&output=json" | ConvertFrom-Json | Select-Object name_value

3. Hardening APIs Against AI‑Powered Credential Stuffing

Scammers use AI to bypass CAPTCHA and rate limiting. Implement behaviour‑based throttling and anomaly detection.

Step‑by‑step configuration (NGINX + Lua):

Limit requests per IP with dynamic sliding window:

limit_req_zone $binary_remote_addr zone=login:10m rate=5r/m;
server {
location /api/login {
limit_req zone=login burst=2 nodelay;
proxy_pass http://auth_backend;
}
}

Add fingerprinting using `User-Agent` and `Accept-Language` entropy:

if ngx.var.http_user_agent then
local ua = ngx.var.http_user_agent
if string.match(ua, "Headless") or string.match(ua, "Python") then
ngx.exit(403)
end
end

Cloud hardening (AWS WAF):

Create a rule to block requests with missing or inconsistent headers:

{
"Name": "BlockMissingHeaders",
"Statement": {
"ByteMatchStatement": {
"FieldToMatch": { "Header": "accept-language" },
"PositionalConstraint": "EXACTLY",
"SearchString": "",
"TextTransformations": []
}
},
"Action": { "Block": {} }
}

Disrupting Scam‑as‑a‑Service Platforms via Threat Intelligence Feed Integration

Malwarebytes’ GASA membership enables automated IOC (Indicators of Compromise) sharing. Set up a local MISP instance to consume and act on feeds.

Step‑by‑step (Linux):

Install MISP (Malware Information Sharing Platform):

git clone https://github.com/MISP/MISP.git /var/www/MISP
cd /var/www/MISP && bash INSTALL/ubuntu.sh

Add a feed from GASA partners:

curl -X POST "http://localhost:8080/feeds/add" -d "url=https://gasa-feeds.example/indicators.json" -H "Authorization: Bearer $API_KEY"

Automate firewall blocking using `ufw` and cron:

!/bin/bash
for ip in $(misp-cli get ioc type=ip); do
ufw deny from $ip to any port 80,443
done

Windows (PowerShell + Defender):

$iocs = Invoke-RestMethod -Uri "https://gasa-feeds.example/indicators.json"
foreach ($ip in $iocs.ipv4) {
New-1etFirewallRule -DisplayName "BlockScam_$ip" -Direction Inbound -RemoteAddress $ip -Action Block
}

5. Social Engineering Awareness Training with AI‑Generated Scenarios

Leverage LLMs to create realistic phishing simulations for employee training.

Step‑by‑step (using GPT‑4 API):

Generate a personalised spear‑phishing email template for internal drills:

import openai
openai.api_key = "your-key"
response = openai.ChatCompletion.create(
model="gpt-4",
messages=[{"role": "user", "content": "Create a convincing but fake IT support urgent password reset email. Include a malicious link placeholder [bash]. Make it look like from Microsoft."}]
)
print(response.choices[bash].message.content)

Deploy using Gophish (open‑source phishing framework):

wget https://github.com/gophish/gophish/releases/download/v0.12.1/gophish-v0.12.1-linux-64bit.zip
unzip gophish-.zip && ./gophish

Track click rates and report to GASA’s shared intelligence dashboard.

6. Mitigating AI‑Generated Voice Deepfakes in Call Centres

Attackers clone voices using few‑second samples. Implement liveness detection.

Command‑line spectrogram analysis (Linux):

Convert audio to spectrogram and look for unnatural frequency gaps:
```
sox suspect_call.wav -1 spectrogram -o spectrogram.png
```

Use `tensorflow‑io` to detect phase‑based artefacts:

import tensorflow_io as tfio
audio = tfio.audio.AudioIOTensor('suspect_call.wav')
Implement a trained model for real vs synthetic (example placeholder)

Recommendation for Windows environments:

Deploy NVIDIA Riva’s voice liveness SDK or integrate Pindrop’s audio fingerprinting API.

What Undercode Say:

Key Takeaway 1: Cross‑sector intelligence sharing (public‑private partnerships) is no longer optional—it is the only scalable defence against AI‑amplified scams.
Key Takeaway 2: Technical countermeasures must move from reactive blocklisting to proactive behavioural detection, including deepfake forensics and API abuse pattern analysis.

Analysis: The summit’s emphasis on collaboration reflects a maturation in cybersecurity: vendors like Malwarebytes now recognise that threat actors use generative AI to automate personalisation at scale. Consequently, static defences fail. The open‑source commands and configurations listed above (DNS enumeration, MISP feeds, deepfake detection) represent the operational layer that GASA members can immediately adopt. However, the missing piece remains standardised, real‑time API for cross‑company IOC exchange—without which many small enterprises will still fall prey to polymorphic scam campaigns. Training, as shown, must evolve from annual slides to AI‑driven, adaptive simulations that mirror actual attacker behaviour.

Prediction:

+1 By 2028, GASA‑like alliances will mandate real‑time threat intelligence APIs, reducing scam dwell time from weeks to minutes.
-1 The democratisation of deepfake‑generation tools will outpace liveness detection, forcing a temporary regression to hardware‑based authentication (e.g., YubiKeys) for all high‑value transactions.
+1 Automated, AI‑driven counter‑scam agents (honeypots with LLM chatbots) will become standard, flooding scam networks with false victims to degrade their ROI.
-1 Regulatory fragmentation between EU, US, and Asia will slow down cross‑border takedowns, allowing scam‑as‑a‑service platforms to migrate to jurisdictions with weak cybercrime laws.
