Prevention Guide
- Online swindlers have recently begun sending emails with malicious programs attached, which pretend to notify the victim of withdrawals from his or her FX account. When the victim opens the attached file, the program installs itself on the victim’s computer to steal his or her personal information. In another case, they have posted ads that claim to offer loans regardless of one's credit status. If you contact them, they pretend to be legitimate bank employees and try to extract personal information from you such as your account numbers and passwords. Then they ask you to deposit cash in the account, saying that they need your banking transaction history to grant you a loan. Later, the scammers move your money to accounts under their control or simply withdraw it. Below are the most frequent scams that you should know about so that you can avoid becoming a victim of fraud.
What is Phishing
- The term “phishing,” which refers to a type of identity theft, was coined by combining “private data” with “fishing.” The swindler links an email message or online bulletin board to a phony financial website to induce victims to reveal their banking information.

Protect Yourself against Phishing
- Never reveal your name or resident registration number to a caller claiming to be from a public office.
- If you receive a call from a financial institution about a late credit card or loan payment, verify the caller’s ID and phone number before doing anything else.
- Certificates of deposit (CDs) are never used to make credit card payments or to pay taxes or health insurance premiums. Do not let a swindler convince otherwise.
- Call your bank to verify the contents of email messages you receive.
- Ensure the website that you linked onto from an email message is the official Citibank Korea website before you enter any important information.
- Contact Citibank Korea directly to see if you qualify for a loan; never send anyone advance fees for a loan.
- If you receive a phone call claiming you have won a lottery prize, call them back to verify it is true. Even if it is, do not reveal compromising personal information.
- Contact your bank or one of the institutions listed below if you receive a suspicious email or phone call requesting personal information and promising a loan that is too good to be true.
