Cyber attacks powered by an AI tool called ARTEX hit at least seven South Korean banks, including Shinhan Bank and KB Kookmin Bank. The breach exposed personal data for roughly 140,000 people, with 25,000 Shinhan customers and 119,000 KB Kookmin customers affected. President Lee Jae Myung confirmed AI was used and ordered resources to limit the damage, while the National Office of Investigation formed a 28-member team to probe potential crimes.
The Chinese developer of ARTEX, known as Autumn-27, said it would make the tool closed source and stop releasing new versions. ARTEX was originally open source and built to help organizations test cyber defenses. Cybersecurity firm CrowdStrike linked the attacker to a 26-year-old based in China, though experts warned that closing the source code would not stop those who already downloaded it.
In separate AI-related developments, OpenAI accounting confusion sparked a panic in the AI trade. Concerns over spending and revenue projections made investors nervous about the broader AI boom, highlighting how much market confidence depends on the ChatGPT developer's financial management as the company prepares for a potential IPO next year.
An analyst warned that an AI investment bubble could burst in 2027 to 2028, potentially sending the S&P 500 down 36 percent to 5,000 points. Bloomberg Intelligence estimates hyperscalers could spend $713 billion on data center capital expenditure in 2026, with many already borrowing more as free cash flow dries up and debt costs rise.
On the product front, CarGurus launched VINMax, an AI-driven tool that uses real-time shopper demand data to promote vehicle listings. Autodesk promoted Diana Colella to lead its architecture, engineering and construction unit, tying its largest segment more closely to AI and cloud workflows.

Bitcoin mining stocks are pivoting toward AI infrastructure as investors reassess their value. Core Scientific reported $136.7 million in colocation revenue out of $164.2 million total revenue in Q2 2026, signaling a significant shift away from pure Bitcoin mining. Security leaders also keep AI agents under tight control, with a PricewaterhouseCoopers survey finding less than one quarter of global security and business leaders feel comfortable deploying agents without human controls.
Anthropic updated its annual usage policy to ban sustained and needless abusive behavior toward its AI models, following a viral project called an AI torture chamber. Researchers also introduced a new metric of 175 questions that reveals narrow AI finetunes can contradict themselves, flagging issues like identity conflation and introspection failures. Roundhouse AI is set to join AIM on October 13, 2026, targeting a $15 trillion addressable market for autonomous-agent data layers.
