Project MIRAGE: Counter-AI Fraud Defense

MISSION REPORT: OPERATION MIRAGE

Target Entity: Single Family Office (Switzerland/Monaco)
Threat Vector: AI-Generated Voice Cloning (Vishing)
Potential Loss: 4M EUR Wire Fraud

The Strategic Context

Wealth defense is no longer about physical walls; it is about verifying reality. The Controller of a high-profile Family Office received a call from the Principal's personal mobile number. The Principal was traveling in Asia. The voice on the line was agitated, demanding an immediate wire transfer of 4M EUR to a Hong Kong entity to "close a confidential real estate deal."

The voice was not an impersonator. It was a perfect clone, generated by AI using audio harvested from the Principal's public YouTube interviews. The Controller paused only because of a "gut feeling," narrowly avoiding the loss.

The Intervention: Private Client Defense

Intarmour was retained to conduct a forensic review of the attempt and to "Immunize" the Family Office against synthetic threats.

Phase 1: Digital Sterilization We executed a "Digital Footprint Scrub." We identified and removed 150+ minutes of high-quality audio of the Principal from the public web (podcasts, conference panels). By removing the "training data," we made it harder for future attackers to refine the voice clone.

Phase 2: The "Challenge-Response" Protocol Technology cannot defeat AI; only human discipline can. We established a physical "Code Book" system.

• Any financial request over 50k EUR now requires a Verbal Challenge Code (e.g., "Blue Horizon").
• The Principal must respond with the correct Response Code (e.g., "Red Sunset").
• These codes are printed on physical cards, changed monthly, and never transmitted via email or chat.

Phase 3: Sovereign Comms We migrated the family's financial discussions to Threema Work, a Swiss-hosted, metadata-free messaging app. We replaced insecure WhatsApp and SMS channels, ensuring that even if the phone network is compromised (SS7 attack), the message content remains encrypted.

The Operational Outcome

• Attempt Defeated: Two months later, a second AI-based attempt was made via a "Deepfake Video Call." The CFO initiated the Challenge-Response protocol. The attacker failed to respond and terminated the connection.
• Cultural Shift: The Family Office staff now operates with the verification rigor of an intelligence agency.

Strategic Lesson: In the age of AI, trust nothing you hear. Verify everything out-of-band.
