[Digital Today reporter Sangyeop Oh] Daishin Securities has 마련ed support measures for customers whose personal credit information was leaked in a recent hacking incident, including enrollment in voice phishing and smishing loss compensation insurance and waivers of domestic stock trading fees.

Daishin Securities said in a notice on its website on Sunday it will implement three support measures for customers affected by the data leak.

First, it will support enrollment in voice phishing and smishing loss compensation insurance for affected customers. The coverage limit is up to 10 million won for one year, and Daishin Securities will enroll customers in a batch without requiring separate applications.

It will also waive domestic stock trading fees for December. It also plans to waive various service fees, including for deposits and withdrawals and security media.

It will also pay 10,000 won in cash per affected customer. The planned payment date is Dec. 1.

Separately from these support measures, affected customers can exercise rights under relevant laws, including filing civil claims for damages or applying for dispute mediation with the Personal Information Dispute Mediation Committee. Daishin Securities explained that the company’s support benefits do not affect such exercises of rights.

Earlier, Daishin Securities detected signs of abnormal access on Oct. 17 on a server linked to the opening of discretionary investment non-face-to-face securities accounts. After conducting a full inspection for 10 days, it confirmed the data leak on Oct. 26 and said on Oct. 27 that personal credit information of about 38,000 people had been leaked.

The leaked information includes eight items, including customer names, email addresses, addresses, telecom IDs, bank names, deposit and withdrawal account numbers, Daishin Securities all-in-one account numbers and mobile phone numbers. Among them, deposit and withdrawal account numbers, all-in-one account numbers and mobile phone numbers were encrypted.

Daishin Securities said it blocked the IP addresses used in the attack and the bypass access routes immediately after recognizing the incident, and reported it to relevant authorities. It has since reinforced its information management system, including blocking abnormal access, and is advancing its integrated security monitoring system.

It will also strengthen its capability to analyze vulnerabilities using artificial intelligence (AI). It plans to add AI functions to its integrated security monitoring system to improve its ability to detect and respond to external attacks.

A Daishin Securities official said, "We take heavily the concern caused by the information leak." The official added, "We will do our utmost to protect customers by thoroughly implementing support measures and guidance on preventing damage, and by swiftly proceeding with relief procedures when additional damage reports are received."
