Financial authorities issued a consumer alert (caution) on the 1st, saying financial fraud damages such as voice phishing and smishing are expected following Coupang's personal information leak incident.
Through the consumer alert that day, financial authorities said, "Scammers approach victims by impersonating government agencies or financial firms based on leaked personal information such as names and addresses," and noted, "There are concerns they will send smishing texts that induce installation of remote-control apps or malicious apps under the pretense of checking leaked information or damage status, or that lure users to enter financial information with guidance on compensation or refunds as a 'Decoy.'"
It added, "Together with the financial sector, we are making an all-out response to prevent secondary damages stemming from personal information leaks," and stated, "Financial authorities have guided financial companies to inspect their rapid response systems for voice phishing damages and to strengthen monitoring of abnormal financial transactions, and we plan to closely monitor trends in damage reports going forward and respond swiftly if damages occur."
Coupang became aware on the 18th of last month that personal information had been leaked from about 4,500 accounts and reported it to the Personal Information Protection Commission (PIPC) on the 20th. A subsequent follow-up probe confirmed that the information leak had continued for an extended period since June 24. During this process, the number of leaked accounts increased to 33.7 million, about 7,800 times the original figure.
