North Korean hackers are running AI locally to industrialize spear phishing
Al Jazeera reports that the North Korea-linked Kimsuky group has used AI-generated documents in spear-phishing attacks targeting military, diplomatic, and academic organizations. South Korean cybersecurity firm Genians says the group is running models locally with open tools including Ollama, GPT4All, and Msty, allowing polished malicious documents to be produced without relying on a monitored online service. The report does not show that AI created Kimsuky's capability or that every open model presents the same risk. It shows how local deployment can reduce cost, increase volume, and remove a provider's ability to detect or revoke abusive use. Defenders must treat language quality as cheap and verify identity, attachment behavior, provenance, and access paths instead of trusting a professional-looking document.
