The financial authorities will hold an emergency response meeting regarding the SK Telecom SIM card (USIM) information leak incident.

The Financial Services Commission noted on the 29th that it will hold an emergency response meeting chaired by Secretary-General Kwon Dae-young on the morning of the 30th to discuss countermeasures related to the concerns of secondary damage from fraudulent financial transactions through SK Telecom SIM card duplication and more. Representatives from the Financial Supervisory Service, the Financial Security Institute, and various financial associations will attend the meeting.

A financial authorities official said, "No specific cases of damage have been confirmed or received yet," adding, "We are currently closely monitoring the situation in the financial sector and plan to implement additional measures immediately if necessary."

The financial authorities requested each financial institution on the 24th not to allow fraudulent financial transactions through SIM card duplication and to strengthen security measures. The FSS stated, "In the future, if authentication is completed solely through mobile phone identity verification or text message verification, consider additional authentication methods," and added, "For mobile financial apps that collect device information, enhance additional authentication for customers whose device information has changed and rigorous monitoring through Fraud Detection System (FDS) for unusual financial transaction detection."

The financial authorities stated that they are accepting reports of financial incidents related to the recent SK Telecom hacking through the financial incident reporting center (☎1322), and will do their best to prevent consumer damage by establishing and operating an emergency response team in the future.

The financial authorities also mentioned that to prevent financial fraud damage, all financial institutions can block online account openings and loan executions through the 'safe blocking service for online account opening and loan transactions,' thereby preventing unauthorized financial transactions from occurring without the individual's knowledge.

In fact, following the SK Telecom hacking incident, it was reported that about 350,000 people applied for the safe block on online account openings and about 450,000 people applied for the safe block on loan transactions over the week from the 22nd to the 28th.
