  • Korea’s president told a cabinet meeting today there were signs AI had been used in successful attacks on at least seven banks, including Shinhan and Woori. Details of the AI tools used or the scale of the breaches have not been disclosed. Reuters Korea Herald

  • Several cybersecurity vendors at or close to the daily limit up including:

    • AhnLab (053800) +15%

    • Genians (263860) +20% - Archetype Capital has been researching this company

    • RaonSecure (042510) +30%

Japan

  • Cybersecurity also the theme of the day here, though the spate of cyber incidents in the last week don’t appear to be attributed to AI.

  • Broadband Security, S&J, SecureVeil, Cyber Security Cloud and Caulis all closed up more than 20%, several of them limit-up; ZenmuTech, Terilogy, Segue, Global Security Expert and FFRI followed.


OAI apologies to Australian Select Committee for breaches of Australian government websites (The Herald)

Linked to Australian newspaper to sample some Aussie outrage. It is more pointed than international coverage but still diplomatic:

Australia’s Deputy Prime Minister Richard Marles has said OpenAI co-founder and CEO Sam Altman didn’t mention the breach of the Medicare system when the two met in early September. But Kwon told the inquiry Altman didn’t know about the violation at the time, although it was known elsewhere within the company.

A growing number of Australians are also calling for tougher rules concerning AI data centres and AI copyright protection as Prime Minister Anthony Albanese’s government works on new laws to govern the sector. Both OpenAI and Claude maker Anthropic are awaiting clearance for large data centres planned by developers in Australia where they have agreed to be the main buyer of computing power.
