[Edaily Reporter PARK MIN ] Amid a string of hacking incidents in the financial sector, a data breach has occurred at the Korea Financial Security Institute, causing security-related stocks to rally across the board in early trading on the 11th.

According to MP Doctor, as of 9:19 a.m. today, AHNLAB,INC.(053800)is trading at 124,900 won, up 15.43% from the previous trading day. #RaonSecure Co., Ltd. is also trading at 15,880 won, up 12.46% from the previous trading day.

Meanwhile, #GENIANS, INC. (10.40%) and #SANDS LAB Inc. (9.57%) are also posting sharp gains of around double digits. Major security stocks across the board, including #FASOO AI (7.35%), #S2W Inc. (6.52%), #ITCENPNS (6.58%), #SGA Solutions Co.,Ltd. (5.96%), and #ATON Inc. (5.95%), are showing a synchronized upward trend in the 5–7% range.

This upward trend is believed to be driven by news that the “Financial Security Institute”—which serves as the control tower for cyber incident response in the domestic financial sector—was itself the target of a hacking attack, resulting in the leak of internal information.

The Financial Security Institute has confirmed that the financial sector’s “ongoing information security assessment” system was compromised by an external attack, resulting in the leak of hundreds of pieces of personal information—including the personal details of security personnel at financial institutions—and has reported the incident to authorities such as the Financial Services Commission.

Amid a recent spate of security breaches at individual private financial institutions, such as securities firms, the exposure of vulnerabilities even at a specialized agency—which serves as the frontline of the financial sector’s security policies—is heightening concerns about the security framework as a whole.

Consequently, analysts note that buying interest is concentrating on related beneficiary companies as expectations grow for a re-examination of security infrastructure and increased budget allocation across public and private enterprises, including financial institutions.
