Introduction
The line between reality and AI-generated fiction has eroded to a razor’s edge. As Emmy Award-winning cyber reporter Kerry Tomlinson prepares to take the stage at the SANS Security Awareness & Culture Summit in Las Vegas (August 27–28, 2026), she brings with her a chilling firsthand account: a two-month undercover investigation posing as a fake Lionel Richie to expose how cybercriminals weaponize deepfakes. This isn’t theoretical—it’s a live fire exercise in deception, where scammers deploy “garage sale AI” alongside sophisticated generative tools to steal data, money, and trust.
Learning Objectives
- Understand the underlying AI architectures (GANs, autoencoders) that enable hyper-realistic deepfake creation and their evolving threat landscape.
- Master practical command-line and forensic tools to detect synthetic media across Linux and Windows environments.
- Develop organizational defense strategies—including API security, cloud hardening, and incident response—to mitigate AI-generated disinformation and impersonation attacks.
You Should Know
- The Deepfake Attack Chain: How Scammers Borrow Trust
Scammers don’t need to invent pressure tactics when they can simply borrow trust. The modern deepfake attack follows a predictable but devastating pipeline: data collection (scraping public videos and audio of a target), model training (using generative adversarial networks or autoencoders to learn facial expressions and vocal cadences), and rendering (synthesizing convincing media).
Tomlinson’s undercover operation revealed that criminals are deploying these synthetic personas across social media, private messaging apps, and even live video calls. In one documented case, a scammer wore a “digital skin suit”—a real-time deepfake overlay—during a live video call to fully impersonate someone to their friends, family, or followers.
Step-by-Step: Simulating a Deepfake Attack Vector
To understand the threat, security teams can simulate the reconnaissance phase:
Linux: Scrape public media for OSINT gathering (educational use only)
youtube-dl -f bestaudio https://www.youtube.com/watch?v=TARGET_ID
ffmpeg -i input.mp4 -vn -acodec pcm_s16le -ar 16000 -ac 1 audio.wav
Windows PowerShell: Extract metadata from downloaded media
Get-ChildItem -Path .\Downloads.mp4 | ForEach-Object {
$shell = New-Object -ComObject Shell.Application
$folder = $shell.Namespace($<em>.DirectoryName)
$file = $folder.ParseName($</em>.Name)
$folder.GetDetailsOf($file, 0)
}
2. Forensic Detection: Metadata Analysis and Artifact Hunting
Detection begins with examining digital artifacts that AI models leave behind. While humans still outperform AI at detecting deepfake videos—correctly identifying fakes about two-thirds of the time—automated tools provide critical scalability.
Linux/macOS Commands:
Extract comprehensive metadata to spot editing software or anomalous timestamps exiftool -a -u -g1 suspicious.mp4 Search for hidden model signatures or generator fingerprints strings video.mp4 | grep -i "deepfake|gan|synthesized|openai|stable" FFmpeg analysis for codec inconsistencies ffmpeg -i video.mp4 -f ffmetadata metadata.txt cat metadata.txt | grep -E "encoder|producer|creation_time"
Windows PowerShell Equivalents:
Install ExifTool for Windows (via Chocolatey) choco install exiftool Extract and filter metadata exiftool -a -u -g1 C:\Forensics\suspicious.mp4 Check file integrity and origin Get-FileHash C:\Forensics\suspicious.mp4 -Algorithm SHA256
Python Automation for Error Level Analysis (ELA):
ELA highlights compression artifacts that differ between original and resaved regions—a telltale sign of manipulation.
from PIL import Image, ImageChops
import sys
img = Image.open(sys.argv[bash])
img.save('temp.jpg', quality=90)
temp = Image.open('temp.jpg')
diff = ImageChops.difference(img, temp)
diff.save('ela_output.png')
3. Audio Deepfake Detection: Voice Cloning Countermeasures
Voice cloning represents one of the most dangerous vectors, enabling CEO fraud and vishing attacks. Scammers clone a celebrity’s or executive’s voice, position the message as urgent or exclusive, and push it via social media ads or streaming sites.
Detection Workflow:
Linux: Spectrogram analysis to detect unnatural frequency patterns sox audio.wav -1 spectrogram -x 300 -y 200 -o spectrogram.png Windows: Use Audacity's spectrogram view (GUI) or command-line via FFmpeg ffmpeg -i audio.wav -af "showspectrum=s=800x400" -frames:v 1 spectrum.png Analyze for phase inconsistencies (common in synthesized speech) ffmpeg -i audio.wav -af "aphaser=type=invert" -f null -
Cloud API Hardening:
Organizations should implement voice biometrics with liveness detection for high-value transactions. Deploy API gateways with rate limiting and anomaly detection to flag unusual access patterns from automated deepfake generation tools.
4. The Human Firewall: Building Deepfake Resilience
Tomlinson emphasizes that awareness programs must evolve beyond “spot the fake” training. Detection alone is no longer enough—attackers are too sophisticated. Instead, organizations must build a culture of verification.
Practical Awareness Program Elements:
- Establish “Trust but Verify” Protocols: Mandate out-of-band verification (e.g., a phone call to a known number) for any financial or sensitive request, even if it appears to come from a C-suite executive.
- Run Deepfake Simulation Drills: Use open-source tools like DeepFaceLab or Faceswap in controlled environments to demonstrate how convincing synthetic media can be.
- Implement Media Literacy Training: Teach employees to look for subtle anomalies—unnatural blinking, inconsistent lighting, audio-video desynchronization, and unusual skin textures.
Incident Response Playbook Snippet:
Linux: Isolate and preserve evidence sudo dd if=/dev/sda of=/mnt/evidence/image.dd bs=4M status=progress Capture network logs sudo tcpdump -i eth0 -w deepfake_incident.pcap Windows: Use FTK Imager or PowerShell for forensic acquisition Get-WmiObject -Class Win32_LogicalDisk | Select-Object DeviceID, Size, FreeSpace Capture running processes Get-Process | Export-Csv -Path C:\forensics\processes.csv
5. Cloud and API Security Against AI-Generated Attacks
Deepfake scams increasingly leverage compromised APIs and cloud services to scale attacks. Defenders must harden their infrastructure against automated abuse.
Key Hardening Measures:
- API Rate Limiting: Prevent brute-force scraping of public media for model training.
- Content Security Policies (CSP): Restrict embedding of synthetic media from untrusted domains.
- Zero-Trust Architecture: Assume every request, even from authenticated users, could be AI-generated.
- Cloud WAF Rules: Deploy web application firewalls with deepfake-specific threat intelligence feeds.
Linux Command for API Log Analysis:
Analyze API logs for suspicious patterns (e.g., abnormal request frequency)
grep "POST /api/generate" /var/log/nginx/access.log | awk '{print $1}' | sort | uniq -c | sort -1r | head -20
Windows Event Log Analysis:
Query Security logs for anomalous authentication attempts
Get-WinEvent -LogName Security | Where-Object { $<em>.Id -eq 4625 } |
Select-Object TimeCreated, Message |
Group-Object -Property { $</em>.Properties[bash].Value } |
Sort-Object Count -Descending

What Undercode Say
- Deepfakes are democratizing deception. The barrier to entry has dropped from Hollywood studios to “garage sale AI”—anyone with a laptop can now clone a celebrity’s face or voice. This democratization means every organization, regardless of size, is now a potential target.
- Detection is a cat-and-mouse game. As detection tools improve, so do generation techniques. The arms race between GAN-based forgery and forensic analysis will intensify, requiring continuous investment in both technology and human training.
- Culture eats technology for breakfast. Tomlinson’s work underscores that the most effective defense isn’t a tool—it’s a skeptical, verification-first organizational culture. Training programs must move beyond awareness to embed “trust but verify” as a reflex.
Analysis: The celebrity scam epidemic is a harbinger of broader threats. If scammers can convincingly impersonate Lionel Richie, they can impersonate your CEO, your board member, or your key supplier. The convergence of generative AI with traditional social engineering creates a threat multiplier that traditional security controls alone cannot defeat. Organizations must adopt a layered defense: forensic tooling for detection, cloud and API hardening for prevention, and continuous awareness training for resilience. The SANS Summit provides a critical forum for sharing these strategies, but the real work begins when attendees return to their organizations and implement what they’ve learned.
Prediction
- -1 The deepfake threat will escalate from celebrity impersonation to targeted corporate espionage, with adversaries using synthetic media to manipulate stock prices, steal intellectual property, and compromise supply chains. By 2027, we will see the first major class-action lawsuit against a company that failed to prevent a deepfake-enabled fraud.
- -1 Regulatory frameworks will struggle to keep pace. Governments will introduce rushed legislation that either overregulates legitimate AI development or fails to address the core problem—the lack of digital provenance standards.
- +1 The cybersecurity industry will respond with a new category of “synthetic media defense” solutions, combining forensic AI, blockchain-based content authentication (e.g., C2PA standards), and behavioral biometrics. This will create a $10B+ market by 2028.
- +1 Organizations that invest early in deepfake resilience—integrating detection tools, updating incident response playbooks, and running simulation drills—will gain a significant competitive advantage in trust and brand reputation.
- -1 The human element remains the weakest link. Despite technological advances, social engineering will continue to bypass technical controls. The most sophisticated deepfake defense is useless if an employee willingly bypasses verification protocols under pressure.
