Seoul, October 28, 2026 (Yes Punjab News)
South Korean brokerage Daishin Securities has reported a data breach affecting 38,490 customers after detecting signs of unauthorised access by hackers last week.
The leaked information included customers’ names, email addresses and mobile phone numbers, the brokerage said on Wednesday, according to Yonhap news agency.
The incident comes amid growing cybersecurity concerns in South Korea, where financial firms and public institutions have faced a series of breaches. A government official said authorities plan large-scale vulnerability inspections covering around 170 key information technology infrastructures in the private sector.
The Ministry of Science and ICT will assess security vulnerabilities at 111 public organisations responsible for managing such infrastructure, focusing particularly on internet-connected systems, including websites and publicly accessible servers. The inspections are expected to be completed by the end of the year.
The latest action follows reports that 16 commercial banks experienced cyberattacks leading to customer data breaches this year.
President Lee Jae Myung has also raised concerns about the incidents and called for cybersecurity approaches suited to the artificial intelligence era.
Separately, South Korea has raised its cyber crisis warning level to “caution”, the second-lowest category in its four-tier system, following the discovery of two critical vulnerabilities in PHP, a programming language widely used to power websites.
The ministry urged businesses and government agencies to update their systems after exploit code for the vulnerabilities became publicly available.
“The flaw found in PHP could affect a number of websites and requires an urgent response as exploit codes have already been made publicly available,” Science Minister Bae Kyung-hoon said in a statement, according to the report.
The warning followed actions by government agencies and companies worldwide to shut down websites in response to the vulnerabilities. Cybersecurity firm Wiz, whose researchers helped uncover the flaws, described them as among the most severe vulnerabilities identified using AI.
