Seoul, South Korea – There has been a recent surge in incidents where personal information is being collected through fraudulent job postings and free giveaways on online marketplaces such as Daangn Market. While these scams may seem harmless at first, there are growing concerns that the collected data could be used for malicious purposes, such as voice phishing.

According to a recent investigation, numerous posts offering remote work opportunities, such as content creation or simple tasks, have been circulating on various online platforms. These posts often require applicants to provide their name, age, and phone number, but after submitting the information, applicants receive no response.

Similarly, there has been an increase in fraudulent listings offering free or discounted products, often involving shipping. Once victims agree to the transaction and provide their address, the seller disappears without sending the product. These fraudulent listings are typically removed within a few days, and the sellers are often new members with little to no transaction history.

"I initially thought it was just a case of a seller changing their mind," said Mr. A, a victim of one such scam. "I only provided my name, age, and phone number, so I didn't think there would be any serious consequences. However, I've seen many similar posts and it's concerning."

Experts warn that personal information collected through these scams can be used for targeted phishing attacks. For instance, individuals who have provided their information could be targeted with threats of exposure for visiting adult entertainment venues or gambling establishments. Additionally, individuals who have expressed interest in investments could be targeted with fraudulent investment schemes.

"Personal information collected through various means is often sold to organized crime groups involved in voice phishing," said a police official. "This information is then used to target specific individuals. Even seemingly harmless personal information can be used to cause significant harm. It's crucial not to share personal information with untrustworthy individuals."
