Hana Bank Blocks New Investment Scam with FDS, Prevents 18.5 Billion Won in Losses
Prevented 1,450 Cases of eSIM Scam
through Advanced FDS Monitoring
Hana Bank announced on August 10 that, through precision monitoring using its Fraud Detection System (FDS), it has prevented losses from the recent nationwide spread of the new investment scam 'KReSIM', successfully protecting customer assets in 1,450 cases, amounting to approximately 18.5 billion won.
The 'KReSIM' investment scam involves eSIM retailers luring investors under the pretense of high returns and multi-level commissions in a business targeting foreign tourists, only to cease settlement of profits and disappear with the collected money. This large-scale new investment scam has resulted in between 20,000 and 30,000 victims nationwide, with losses estimated in the hundreds of billions of won.
This scam, in particular, combines the Ponzi scheme model—where profits for existing investors come from new investors' funds—with a multi-level marketing membership structure. As a result of this structural complexity, banks often recognize the fraud only after significant damage has occurred, making it a crime type that is exceptionally difficult for financial institutions to prevent in advance.
In response, in February this year, Hana Bank established an immediate response system and developed monitoring scenarios in its own FDS to include the 'KReSIM' investment scam patterns, proactively undertaking comprehensive prevention measures.
When any transaction signal to a 'KReSIM' corporate account was detected, the bank immediately refused the transaction and blocked the installation and login process of the mobile banking app, preventing further outflow of funds. Alongside this, the bank conducted close customer care, which included sending emergency alerts via KakaoTalk, providing one-on-one risk counseling through dedicated staff, and guiding customers to report to the police.
