I am curious about how to respond when I have suffered financial transaction fraud.

Hello. The case you described corresponds to financial transaction fraud, which has been rapidly increasing recently, in particular a loan-pretext type of fraud.

It is a method in which, through secondhand transactions, loan offers, investment solicitations, and the like, the perpetrator obtains the victim's account information, verification numbers, identification card, and the like, and then steals the victim's identity to induce financial transactions or to carry out illegal loans.

To respond to such financial transaction fraud, you must promptly take the following measures.

- Request a payment suspension: As soon as you confirm the harm, call the bank concerned or visit a branch and apply for a payment suspension on the account used in the fraudulent transaction.

- File a report of the harm: Submit a report of telecommunications-based financial fraud to the competent police station or the 'Integrated Report Center for Telecommunications-based Financial Fraud (112, without an area code)' to officially file the case.

- Check for identity theft: Through the 'Identity Theft Check Service' on the website of the Financial Supervisory Service, check the details of all accounts and financial products opened in your name to see whether there are any abnormal transactions.

- Secure supporting materials: You should collect all materials that can serve as proof, such as text messages, KakaoTalk messages, recordings, remittance records, and screens showing the transmission of verification numbers exchanged with the other party, as this will help in later criminal punishment and civil litigation procedures.

Because recovering from fraud harm is realistically not simple, you should, in parallel with the police investigation, also review civil procedures such as a claim for damages or a claim for the return of unjust enrichment, and there may be room to hold the perpetrator or the person who lent their name jointly liable.

Because the matter is complex, we recommend that you consult with an attorney experienced in responding to financial fraud as soon as possible and set the direction of your criminal and civil response together.
