CYB-02Two Seoul
Two Seoul megachurches probe breaches after nearly a million member records turn up on an attacker's server, with signs of AI tooling
Security firm Oasis Security said it found about 960,000 member records, roughly 330,000 donation records and more than 47GB of internal material, including electronic approval documents and messenger logs, from Yoido Full Gospel Church on an overseas attacker server, along with data on about 89,000 members and 286 staff of Sarang Church (Hankook Ilbo, MBC). According to Hankook Ilbo, attackers used a web shell to get into Yoido's systems and previously obtained account credentials at Sarang, and the data appears to have been taken in August. Yoido Full Gospel Church said data tied to about 850,000 members, mainly names and dates of birth plus a smaller number of national ID numbers, addresses and phone numbers, may have been compromised, and Oasis Security said attack records showed signs that AI tools were used, including references to “sub-agents” and extensive attack reports that appeared to be generated automatically (Fox Business, with Reuters). Yoido said it was blocking external access and changing server passwords, and Sarang formed an emergency task force and reported the incident to authorities. No attacker has been identified.
Analytic judgmentThe AI finding rests on a security firm's reading of attack logs rather than an official investigation, and no attacker has surfaced, so Korean authorities (KISA, the Personal Information Protection Commission or police) are unlikely to publicly name who was behind the breaches by 2026-10-31.
Likelihood Unlikely (20–45%)Confidence Low

Kospi falls 1.98% to 6,803.90 as foreign investors dump chip stocks ahead of Samsung's results
Korea's Kospi fell 1.98% to 6,803.90 on Oct 7, its second straight decline. Foreign investors sold a net 2.6 trillion won ($1.94 billion) and institutions about 670 billion won, while individuals bought a net 2.56 trillion won, with Samsung Electronics and SK hynix leading the losses, Korea JoongAng Daily and Aju Press reported. Aju Press said investors held back ahead of Samsung's preliminary third-quarter results on Thursday, Oct 8, and that Samsung lost buying support after completing a share buyback; JoongAng Daily also pointed to worries over bond yields at multidecade highs. The slide came even though U.S. stocks rose on Tuesday, with the S&P 500 at 7,818.93 (+0.58%) and the Nasdaq at 27,599.89 (+0.45%).
Analytic judgmentForeign selling is concentrated in large chipmakers, which makes Samsung's Oct 8 results the near-term swing factor, but U.S. long-term yields and $100 oil still weigh, so it is a roughly even chance that foreign investors post a net purchase of Kospi shares on at least one of Oct 8 or Oct 9 (by 2026-10-09).
