The convenience of the digital marketplace has a dark mirror. As South Korea’s second-hand trading ecosystem expands through platforms like Karrot (Danggeun) and Bungaejangter, a sophisticated wave of ì¤‘ê³ ê±°ëž˜ 피해 (second-hand transaction fraud) is evolving, leaving thousands of consumers vulnerable despite the presence of built-in security measures.
For years, “safe payment” (ì•ˆì „ê²°ì œ) services—which hold funds in escrow until the buyer confirms receipt of the item—were marketed as the gold standard for preventing scams. However, fraudsters have pivoted. Rather than avoiding these systems, they are now weaponizing the perception of safety, creating meticulously forged payment portals that mimic legitimate platforms to steal both money and personal information.
The scale of the problem is significant. According to data from the Korean National Police Agency, fraud reports related to second-hand trades consistently rank among the highest categories of cybercrime. The shift is no longer just about “ghosting” after a bank transfer; It’s about psychological manipulation and technical deception.
The Anatomy of the ‘Safe Payment’ Mirage
The most prevalent fresh tactic involves the “fake link” scam. In this scenario, a seller agrees to use a safe payment system to put the buyer at ease. They then send a URL via a third-party messenger—such as KakaoTalk—claiming it is the official payment page for the platform. To the untrained eye, these pages look identical to the real interface, complete with official logos and familiar layouts.
Once the victim enters their credentials and payment details, the money is transferred directly to the fraudster’s account. The scam often escalates through a “refund loop.” If the victim realizes the amount was entered incorrectly or the transaction failed, the fraudster claims they must send a larger sum to “unlock” the previous payment or trigger a refund, effectively doubling or tripling the financial loss in a matter of minutes.
This method is particularly insidious because it targets the user’s trust in the system. By pretending to follow the platform’s safety protocols, the scammer lowers the victim’s natural defenses, making them more likely to overlook red flags like a slightly misspelled URL or a request to move the conversation off-platform.
Common Red Flags in Modern Transaction Scams
- Platform Migration: The seller insists on moving the chat from the official app to KakaoTalk or Telegram.
- External Links: The use of a URL sent via chat for payment, rather than using the app’s integrated payment button.
- Urgency and Pressure: Creating a false sense of scarcity, claiming other buyers are waiting and the victim must pay immediately to secure the item.
- Request for Extra Funds: Demanding additional money to “correct” a mistake or provide a “security deposit” for a refund.
The Financial and Psychological Toll
While some losses are small, the cumulative impact is substantial. For many young users, these scams represent a significant financial blow. Beyond the monetary loss, there is a systemic erosion of trust in the “sharing economy.” When a tool designed for community trust is used as a weapon for theft, it complicates the growth of legitimate peer-to-peer commerce.
The complexity of these crimes too makes recovery difficult. Fraudsters frequently use “daepo-tongjang” (borrowed or stolen bank accounts) to mask their identities. By the time a victim realizes they have been scammed and reports it to the authorities, the funds have often been moved through multiple accounts or converted into cryptocurrency, making them nearly impossible to retrieve.
| Feature | Traditional Scam | Modern ‘Safe Payment’ Scam |
|---|---|---|
| Method | Direct bank transfer, then disappearance. | Phishing links mimicking escrow services. |
| Psychology | Reliance on a “good deal” price. | Reliance on “system security” and trust. |
| Complexity | Low; simple theft. | High; involves social engineering and fake UI. |
| Recovery | Possible via account freezing. | Difficult due to rapid fund laundering. |
Systemic Responses and User Protection
Platform operators are attempting to combat this by implementing “warning pop-ups” and banning users who share external links. However, the cat-and-mouse game continues as scammers find new ways to bypass filters. Experts suggest that the only foolproof method is to strictly adhere to the platform’s internal payment systems and never click on links sent via external messaging apps.
For those who have fallen victim, the Cyber Bureau of the National Police Agency recommends immediate reporting and the provision of all chat logs and transaction records. While the chance of recovery varies, reporting helps authorities track the networks of accounts being used by professional fraud rings.

The next critical checkpoint for consumer protection will be the ongoing review by the Fair Trade Commission regarding the liability of platform operators in facilitating these transactions. As the legal framework evolves to define the responsibility of the “marketplace” versus the “individual,” users are encouraged to remain vigilant and prioritize verified payment methods over convenience.
