The scammers begin the scam by posing as bank representatives over the phone, claiming that the victim’s online banking credentials have expired, creating a false alarm. Using this pretext, they solicit personal data from unsuspecting corporate users. Victims then receive well-crafted phishing emails with malicious links that lead to fake websites that mimic legitimate banks.
HackManac researchers observed that once victims enter these websites, they are prompted to enter their login credentials, thereby handing over sensitive information to the scammers. Armed with this data, the scammers gain unauthorized access to corporate accounts and proceed to transfer funds to unrelated accounts, making the transactions difficult to trace and reverse.

This complex money‑laundering method adds a layer of complexity to the fraud, making recovery efforts more difficult. The emergence of this fraud comes amid increased cybercrime in Japan. In the first half of 2023 alone, 2,322 online banking frauds were recorded, with losses of about 3 billion yen (approximately $21 million).
This new scam could significantly increase these figures if no measures are taken. Experts urge corporate users to be especially careful, to verify any unsolicited communication from banks through official channels, and to avoid clicking on suspicious links or providing sensitive information without proper verification.
