The information displayed in the AIM should not be reported as representing the official views of the OECD or of its member countries.

SK Telecom and the Korean National Police deployed an AI-based system to analyze malicious apps, identifying 475 criminal servers and preventing financial harm to 643 people in just three months. This collaboration is estimated to have averted losses of approximately 163.8 billion KRW annually from voice phishing scams.[AI generated]

Why's our monitor labelling this an incident or hazard?

The article explicitly mentions the use of an AI-based analysis system to detect and analyze malicious apps used in voice phishing scams. The AI system's outputs were used by law enforcement to identify criminal infrastructure and prevent financial harm to hundreds of victims, amounting to billions in prevented losses. This is a clear case where the AI system's use directly led to harm prevention, which fits the definition of an AI Incident involving harm to persons (financial harm) and communities. The event is not merely a potential risk or a general update but a concrete case of AI-enabled harm mitigation.[AI generated]

Why's our monitor labelling this an incident or hazard?
An AI system is explicitly involved in analyzing malicious apps and extracting command-and-control server information, which is then used to prevent financial fraud and harm. The event reports realized harm prevention (643 victims protected, significant financial losses avoided), indicating direct positive impact on preventing injury to people (financial harm) and harm to communities. Therefore, this qualifies as an AI Incident because the AI system's use has directly led to harm prevention, which is a form of harm addressed in the framework (harm to people and communities).

Why's our monitor labelling this an incident or hazard?
The article explicitly mentions an AI system analyzing malicious apps to identify phishing servers, which directly led to preventing financial harm to 643 individuals and stopping significant monetary losses. The AI system's involvement is in its use for harm prevention, which is a direct link to harm (financial harm to people prevented). This fits the definition of an AI Incident because the AI system's use has directly influenced harm outcomes (prevention of injury to persons via financial fraud). Although the harm is prevented, the event concerns realized harm scenarios and the AI's role in mitigating them, which qualifies as an AI Incident rather than a hazard or complementary information.

Why's our monitor labelling this an incident or hazard?
An AI system is explicitly involved in analyzing malicious apps to detect and prevent voice phishing scams, which directly prevents financial harm to individuals (harm to persons/groups). The AI system's use in this context has already led to the prevention of monetary losses, which qualifies as harm avoidance. Since the AI system's use has directly contributed to preventing harm, this event is best classified as Complementary Information because it reports on the successful application and enhancement of AI tools in response to an existing crime problem rather than describing a new AI Incident or Hazard. The article focuses on the cooperation and improvements rather than a new harm caused or a plausible future harm from AI itself.

Why's our monitor labelling this an incident or hazard?
The article explicitly mentions the use of AI security technology to analyze phishing apps and identify crime servers, which has directly prevented financial harm to hundreds of victims. The AI system's use in detecting and preventing telecommunication and financial fraud fits the definition of an AI system involved in use leading to harm prevention. Since the harm (financial fraud) is real and the AI system's involvement is direct and instrumental in preventing it, this qualifies as an AI Incident rather than a hazard or complementary information.

Why's our monitor labelling this an incident or hazard?
The article explicitly mentions an AI system developed and used by SK Telecom to analyze malicious apps related to voice phishing. The AI system's outputs are directly used by law enforcement to prevent financial harm to victims, which constitutes harm to people (financial harm). The prevention of harm through AI use is a direct positive impact, but since the AI system's involvement is central to preventing harm that would otherwise occur, it qualifies as an AI Incident. The event involves the use of AI in a real-world context leading to the prevention of injury (financial harm) to people, meeting the criteria for an AI Incident rather than a hazard or complementary information.
