INTERPOL reported that Operation HAECHI IV led to almost 3,500 arrests and the seizure of USD 300 million in assets across 34 countries. The six-month operation targeted online fraud and related money laundering from July through December 2023; the figures were announced on 19 December 2023.
What was Operation HAECHI IV?
HAECHI IV was an international law-enforcement operation coordinated through INTERPOL to investigate online fraud and trace the money connected to it. Its targets included voice phishing, romance scams, online sextortion, investment fraud, money laundering linked to illegal online gambling, business-email compromise and e-commerce fraud.
The operation focused not only on the people suspected of carrying out scams, but also on the financial infrastructure used to receive, move or conceal proceeds. That meant coordinating across borders to identify accounts and interrupt payments as investigators pursued cases.
What did authorities report seizing and blocking?
INTERPOL said authorities seized USD 300 million in assets: USD 199 million in hard currency and USD 101 million in virtual assets. Separately, they blocked 82,112 suspicious bank accounts. A blocked account is not the same thing as a seized asset, and the announcement does not say that every blocked account contained criminal proceeds.

The figures describe operational outcomes reported by INTERPOL, not a final accounting of money returned to victims. The release did not establish a complete victim-loss total or say that all seized assets had been permanently forfeited.
Which fraud categories made up most investigated cases?
Investment fraud, business-email compromise and e-commerce fraud accounted for 75% of the cases investigated during the operation, according to INTERPOL. That is a share of investigated cases, not a breakdown of the USD 300 million in seized assets or a measure of victims’ total losses.
Rank #2
Investment fraud
These schemes typically persuade people to send money into a purported investment. The operation included investment fraud among its targets, but INTERPOL’s release did not provide a separate count of cases or losses for this category.
Business-email compromise
In business-email compromise, criminals use or impersonate email accounts to deceive an organization or individual into making a payment or sharing sensitive information. The category was among those targeted and, together with investment fraud and e-commerce fraud, represented the majority share of investigated cases.
Rank #3
E-commerce fraud
E-commerce scams exploit online buying or selling, for example by deceiving people during a transaction. The release identified this as a major category but did not give a separate total for its cases or associated proceeds.
How did the international payment response work?
Investigators used INTERPOL’s Global Rapid Intervention of Payments, or I-GRIP, to coordinate stop-payment action and account freezes. The aim is to help police in different jurisdictions act quickly when a suspicious transfer crosses borders, rather than allowing funds to move beyond reach while agencies exchange information.
Rank #4
INTERPOL also reported that officers identified 367 virtual-asset accounts linked to transnational organized crime. That figure refers to accounts identified, not necessarily accounts seized, and should not be added to the total of blocked bank accounts.

INTERPOL warned about criminals using AI-generated synthetic content, deepfakes and voice cloning for impersonation, sexual blackmail and investment fraud. It also highlighted NFT “rug pulls,” in which promoters attract buyers or investors before abandoning a project or draining its value.
Best Value
These warnings describe emerging fraud risks raised by INTERPOL; the operation’s public announcement does not establish that every one of these technologies was used in the cases behind the arrest and seizure totals. AI-generated voice or video can make impersonation more convincing, but the underlying financial risk remains familiar: someone is pressured to send money, disclose access credentials or act on a false claim.
What the headline does—and does not—show
The headline figures signal the scale of a coordinated cross-border enforcement effort. They do not, by themselves, show how many victims were compensated, how many cases ended in convictions, or the country-by-country distribution of arrests. An arrest is not a conviction, and a reported seizure does not prove that assets have been finally forfeited or returned.
For individuals and businesses, the practical lesson is to verify unexpected payment instructions through a separate, trusted channel—especially when a message creates urgency or asks for a change in bank details. A familiar name, email address, or voice is not enough to authenticate a payment request.
