# Incident Report: Project "Triangle" Pig Butchering Scam
## Executive Summary
A Vietnamese national, Trung Nguyen Van, was charged with money laundering for his involvement in a massive "pig butchering" cryptocurrency scam that defrauded a single victim of $16 million and handled over $53 million in illicit funds.

## Timeline of Events
### Initial Access
- **Date/Time:** Ongoing (Active period June – August 2024 for the primary victim)
- **Vector:** Social Engineering (Romance baiting/Investment solicitation)
- **Details:** Fraudsters contacted targets via social media, dating sites, and messaging apps to build trust and present a fraudulent investment opportunity.
### Lateral Movement
- **N/A:** As this was a fraud scheme rather than a network breach, movement involved the psychological manipulation of the victim to gain access to their capital.
### Data Exfiltration/Impact
- **Victim Action:** The primary victim transferred approximately $16 million in cryptocurrency to wallets controlled by Van.
- **Laundering:** Van transferred the funds from his wallet to private, "unhosted" crypto wallets off centralized exchanges to obscure the audit trail.
### Detection & Response
- **Detection:** Victim reports and blockchain tracing by federal authorities linked the $16 million loss to Van’s specific wallet address.
- **Response Actions:**
- September 22, 2024: Van entered the US via the San Ysidro border.
- September 24, 2024: Van was arrested at LAX before boarding a flight to Taiwan.
- Federal charges for money laundering were filed.
## Attack Methodology
- **Initial Access:** Social Engineering (Pig Butchering). Building long-term trust via messaging apps.
- **Persistence:** Continuous psychological manipulation to encourage repeated "investments."
- **Privilege Escalation:** N/A.
- **Defense Evasion:** Use of unhosted, private wallets and transferring assets off centralized blockchain networks to avoid exchange-based AML (Anti-Money Laundering) triggers.
- **Credential Access:** N/A (Victim-authorized transfers).
- **Discovery:** Identifying high-net-worth individuals on social/dating platforms.
- **Lateral Movement:** N/A.
- **Collection:** Gathering of cryptocurrency assets (BTC/ETH/USDT not specified, but crypto-based).
- **Exfiltration:** Direct transfer of victim funds to actor-controlled wallets.
- **Impact:** Financial devastation of the victim ($16M) and wider scheme impact ($53M+).
## Impact Assessment
- **Financial:** $16 million loss for the primary victim; over $53 million in total suspicious flows through the defendant's wallet.
- **Data Breach:** N/A (Financial fraud focus).
- **Operational:** N/A.
- **Reputational:** Significant loss of public trust in decentralized investment platforms.
## Indicators of Compromise
- **Network Indicators:** Fraudulent investment domain: `Triangle[.]com` (or variations thereof).
- **Behavioral Indicators:**
- Unsolicited contact from individuals on social media regarding financial gains.
- Refusal to allow withdrawals from investment platforms.
- Demands for "taxes" or "fees" to release existing funds.
## Response Actions
- **Containment:** U.S. law enforcement monitoring of border entry/exit points.
- **Eradication:** Arrest of the key money launderer and seizure of related accounts.
- **Recovery:** Ongoing investigation to trace and potentially claw back assets from unhosted wallets.
## Lessons Learned
- **Blockchain Transparency:** While crypto is used for laundering, the public nature of the blockchain allowed law enforcement to trace $16 million directly to the defendant's wallet.
- **Physical Intervention:** Digital crimes often require traditional law enforcement (border security) to achieve a successful resolution.
- **Human Factor:** Technological defenses are bypassed when victims are psychologically manipulated into authorizing transactions.
## Recommendations
- **For Individuals:** Exercise extreme skepticism toward investment advice received through dating apps or unsolicited social media messages.
- **For Exchanges:** Implement stricter monitoring for "pig butchering" patterns, such as large transfers to newly created unhosted wallets following high-frequency messaging.
- **For Organizations:** Increase public awareness campaigns regarding the "Pig Butchering" methodology.
