Samsung forecasts record Q3 profit on AI chip demand; Korea posts current account surplus

Samsung sees record Q3 profit on AI chip demand; Korea posts $46.1B surplus; CrowdStrike links AI attacks to banks.

The Bank of Korea said Thursday that South Korea posted a current account surplus of US$46.1 billion in August, up US$4 billion from a month earlier. The central bank, based in Sejong, said the surplus was the second-highest on record and was driven by robust exports during the global semiconductor upcycle.

CrowdStrike, a U.S. cybersecurity firm, said an unidentified hacker believed to be a Chinese speaker used artificial intelligence-powered hacking tools to breach multiple South Korean financial institutions and steal data. In a report released Wednesday U.S. time, the company said the attacker used ARTEX, an open-source AI-powered penetration-testing tool developed in China, along with large language models, to carry out the cyberattacks between late September and early October.

In Seoul, observers said Thursday that the newly launched Serious Crime Investigation Agency could face friction with police over an unclear jurisdictional line. The agency, dedicated to investigating "major crimes," began operations at the start of this month under a recent revision to the Criminal Procedure Act. That revision effectively dismantled the previous prosecution system, leaving the prosecution with only the right to indict criminals and maintain indictments against them.

Seoul shares extended losses late Thursday morning, tracking Wall Street's downturn, as elevated oil prices stoked inflation concerns. After opening 0.07 percent higher, the benchmark Korea Composite Stock Price Index backtracked almost immediately and was trading down 54.22 points, or 0.8 percent, at 6,749.68 as of 11:20 a.m.
