A North Korean hacking group built large language model tools and collected software that could help automate cyberattacks, analyse stolen material and produce more convincing phishing ?campaigns, a South Korean cybersecurity firm said on Monday.
The cybersecurity firm, Genians, said it found evidence that the North Korean-linked group Kimsuky had set up tools for running and managing AI models locally, including Ollama, GPT4All and Msty, alongside document ?search technology known as retrieval augmented generation
(RAG).
According to the company, the tools could allow operators to process documents without sending sensitive information to outside AI services. Genians also found AI agent development frameworks, speech-to-text software and Cursor, an AI-assisted coding tool, on infrastructure it linked to the campaign.
The findings suggest Kimsuky is moving beyond using generative AI to create phishing lures and is building capacity ?to ?integrate existing AI models into malware development, data analysis and attack automation, Genians said in a report.
