The Chinese AI agent Artex was used to hack at least seven financial institutions in South Korea, resulting in the theft of personal data from approximately 68,000 individuals, including information on income and credit limits.

Artex autonomously identifies vulnerabilities and builds attack chains

Artex's main feature is its ability to detect entry points, select exploits, and construct a sequence of actions to compromise systems with minimal human involvement.

The specific AI model used in the attacks is unknown

Artex itself is not a standalone model: the agent can be connected to GPT, Claude, or DeepSeek, but the specific configuration used in these incidents was not disclosed.

Incident called one of the first large-scale AI hacks of financial institutions

The event has been described as one of the first large-scale cases of AI being used to hack financial institutions. The individuals behind the attacks have not yet been identified.
