On September 4, 2026, the US Treasury’s Financial Crimes Enforcement Network (FinCEN) issued an alert linking approximately $12.7 billion in suspicious activity to digital-asset investment scams run by overseas scam centers.

Record £250,000 loss to deepfake investment scam in Northern Ireland

The Police Service of Northern Ireland (PSNI) reported on September 8 that a victim lost £250,000 to an AI deepfake investment scam.

Japan records worst-ever H1 fraud losses from SNS investment scams

Japan’s National Police Agency reported that special fraud losses reached a record 181.6 billion yen (approx. $1.2 billion USD) in the first half of 2026, a 50% increase from the same period last year. SNS-type investment and romance scams accounted for over 40% of these losses, marking the highest half-year total on record. The surge is attributed to aggressive advertising on social media platforms targeting inexperienced investors.

UK banks reimburse 89% of APP fraud victims under new rules

According to a recent report by UK Finance, 89% of in-scope Authorized Push Payment (APP) fraud cases were reimbursed to victims in the first 15 months following the implementation of new Payment Systems Regulator (PSR) rules. These rules, which came into force in October 2024, mandate that payment service providers reimburse eligible victims. The data indicates that while reimbursement rates are high, the total value of fraud remains a significant national security threat, with criminals stealing nearly £1.3 billion annually.

Local view

In South Korea, local media such as Asia Economy and Edaily highlight the effectiveness of the government's comprehensive countermeasures, noting a 40% reduction in voice phishing cases and a 43% drop in financial losses since the implementation of stricter controls last year. The Herald Corporation notes that despite these gains, fraudsters are evolving, now using "account threats" to freeze legitimate business accounts by falsely claiming they are linked to voice phishing, demanding settlements to release funds.
