A specialized scam-based variant of Investment Fraud wherein criminals first establish false trust or relationships (often romantic or friendly) before urging victims to invest in fraudulent or manipulated opportunities, commonly centered around cryptocurrency. These scams—also referred to as Sha Zhu Pan—are frequently orchestrated by large criminal organizations in Southeast Asia, sometimes involving labor trafficking to staff call centers. Victims are led to believe they can generate high returns from seemingly legitimate trading applications or websites that display fictitious profits and temporarily allow small withdrawals to inspire further investments. In many cases, perpetrators direct victims to deposit funds into specific crypto wallets, decentralized exchanges, or even Bitcoin ATMs, which adds additional layers of obfuscation. Once the victim has deposited substantial capital, the scammers abruptly seize the funds, often routing them through multiple wallets and accounts to conceal the source, thereby complicating detection and AML efforts. These methods blend elements of romance fraud and investment fraud, exploiting personal trust and sophisticated laundering techniques to expand illicit proceeds on a global scale.
Pig Butchering
Sha Zhu Pan
Romance Investment Scam
Tactics
Scammers create false romantic or friendly bonds to manipulate victims into fraudulent crypto investments. This tactic enables scammers to acquire illicit capital directly, as victims deposit substantial amounts into scam accounts or wallets.
Risks
Criminals exploit the inherent features of cryptocurrency products, such as rapid transfers, anonymous or pseudo-anonymous wallet addresses, and minimal KYC requirements at certain crypto ATMs, to layer and obscure stolen funds. This product-focused vulnerability is distinct from the channel dimension, as it directly facilitates the laundering of illicit proceeds following the initial online scam.
Pig Butchering relies primarily on online-based communications, including social media, messaging apps, and fraudulent trading websites, to build victims’ trust and solicit investments. These digital channels span multiple jurisdictions and are often backed by call centers operating from overseas, making oversight and enforcement difficult. This broad, internet-driven approach is the central vulnerability exploited by scammers to contact, groom, and defraud victims at scale.
Many pig butchering operations are orchestrated by organized crime groups in Southeast Asia, leveraging regions with weaker AML enforcement or limited cross-border oversight. By situating call centers and operational hubs in these jurisdictions, scammers can more easily evade scrutiny, hamper international investigations, and exploit uneven regulatory frameworks across multiple countries.
Indicators
Inability or reluctance by the customer to provide clear, consistent documentation on the origin of funds used for investments in unverified or recently established digital platforms.
Multiple rapid transfers from a single account to newly established or frequently changing cryptocurrency wallets within a short time frame, consistent with layering patterns.
High frequency and volume of cryptocurrency conversion transactions that deviate from the customer's historical investment profile.
Rapid movement of funds through multiple accounts, including cross-jurisdiction transfers, without documented commercial or personal reasons.
A prolonged period of personal online engagement, where communications mix social or romantic overtures with financial advice before encouraging high-risk investments.
Use of language in communications that blurs personal relationships with financial transactions, such as combining romantic or friendship elements with investment solicitations.
Frequent alterations or discrepancies in customer identification details or beneficiary information during periodic due diligence checks, especially when linked to incoming investment funds.
Initiation of investments via newly created or unregulated platforms that lack transparency and standard regulatory oversight, prompting enhanced due diligence.
A rapid escalation in the amount of funds invested following an extended period of relationship-building with an online contact, deviating from the customer’s usual financial behavior.
Funds being funneled back into the customer’s account as seemingly legitimate returns after short-term, high-frequency investments, obscuring the original illicit proceeds.
Frequent or large transactions through Bitcoin ATMs or decentralized exchanges without historical usage or legitimate explanation, especially after online communications referencing high-yield investments.
Repeated account access or transaction instructions originating from IP addresses associated with high-risk jurisdictions or known scam call-center clusters, lacking credible business rationale.

Mitigations
Implement scenario-based monitoring and alerts specifically tuned to romance-based scam behaviors. For example, flag sudden surges in cryptocurrency purchases, repeated transfers to newly created wallets after periods of personal relationship building, or abrupt and substantial deviations from a customer’s normal investment pattern. Prompt alerts enable timely investigation and intervention to disrupt large fraudulent outflows characteristic of Pig Butchering.
Leverage specialized analytics to trace digital asset flows from victim deposits through multiple wallet hops to identify suspected Pig Butchering rings. Scrutinize unusual wallet clusters, rapid layering, and transfers that lack economic rationale. By mapping the on-chain flow, institutions can better detect large-scale crypto fraud, freeze illicit proceeds, and support law enforcement investigations.
Train frontline and investigative teams to recognize Pig Butchering indicators, such as clients mentioning romantic or personal connections that quickly lead to substantial crypto investments in unregulated platforms. Equip staff with case examples and escalation procedures for suspicious communications or transaction patterns. This ensures early detection of romance-centric scams and more effective coordination with compliance specialists.
Provide targeted educational campaigns and explicit warnings about romance or friendship-based investment solicitations that direct victims to unregulated or newly established digital platforms. Highlight typical Pig Butchering red flags such as unrealistic profits, abrupt requests for more funds after small 'test' withdrawals, and pressure to use Bitcoin ATMs or decentralized exchanges. By equipping customers with clear warning signs, institutions reduce the likelihood of large-scale fraudulent transfers.
- Educate customers on the dangers of unsolicited investment offers.
- Emphasize the importance of verifying the legitimacy of digital platforms.
- Encourage skepticism towards promises of high returns with minimal risk.
- Alert customers to the tactics used by fraudsters, such as urgency and secrecy.
- Promote the use of secure and regulated financial channels.
Conduct open-source research on crypto platforms and investment opportunities that arise from romantic or friendly introductions. Scrutinize online forums, negative news articles, or regulatory warnings implicating them in Pig Butchering. Use independent data to confirm licensing status and track record. By verifying the legitimacy of purported investment avenues, institutions can warn customers before funds are transferred.
Restrict or temporarily pause high-value transfers to crypto addresses or platforms flagged by negative media, scam reports, or suspicious clustering analytics. When romantic or personal relationship-based investments are identified, enforce additional verification steps for large or repeated transactions to recently established exchanges. This prevents the quick dissipation of victim funds and disrupts funneling or layering attempts emblematic of Pig Butchering schemes.
Continuously re-check customer profiles for newly emerged risk indicators consistent with Pig Butchering, such as abrupt spikes in cryptocurrency turnover or conflicting explanations for large inflows and outflows. Investigate red flags like relationships formed online that precede steep investment activity and questionable documentation of investment platforms. By refreshing CDD data regularly, institutions can catch evolving scams before major losses occur.
Instruments
- Fraudsters provide wallet addresses that masquerade as authentic investment accounts, prompting victims to transfer significant sums of cryptocurrency.
- Privately controlled by the scammers, these wallets allow for the swift movement of stolen digital assets across numerous wallet addresses, masking the funds’ true ownership and frustrating AML detection.
- Criminals direct victims to deposit tangible funds (e.g., wire transfers, cash, or other bank-based payments) into fraudulent trading accounts or Bitcoin ATMs controlled by the scammers.
- This straightforward channel facilitates the initial placement of victim money into the scam ecosystem before quickly converting it into cryptocurrency, making it more difficult for authorities to recover the stolen capital.
- Scam organizers direct victims' investments into well-known cryptocurrencies such as Bitcoin or Ethereum, making them appear as legitimate trading addresses.
- Once received, perpetrators quickly transfer these funds across multiple addresses or exchanges, exploiting the global accessibility and pseudo-anonymity of public blockchains, which complicates law enforcement's ability to identify the final beneficiaries.
Service & Products
- Fraudsters leverage decentralized exchanges and automated protocols to swap or redistribute stolen cryptocurrency.
- Such transactions are executed without traditional KYC procedures, enabling rapid layering that complicates tracking and recovery of illicit funds.
- Fraudsters pose as or direct victims to fraudulent trading platforms that appear to be legitimate exchanges, offering high returns on cryptocurrency investments.
- Once victims deposit fiat or crypto, perpetrators swiftly move the funds through multiple accounts or wallets, obscuring the true recipients and complicating law enforcement tracking.
- Scammers direct victims to Bitcoin ATMs to convert fiat currency into cryptocurrency, often with minimal identity checks.
- This conversion process facilitates quick cross-border movement of illicit proceeds, bypassing traditional banking oversight.
- Criminals instruct victims to send funds to specific crypto wallet addresses under their control, concealing beneficial ownership.
- They then layer the stolen proceeds across multiple digital wallets to further obfuscate the source and hinder AML detection efforts.
