Abstract: An information processing apparatus (2000) extracts, from a communication history (20) representing a history of network communication performed by each of a plurality of mobile terminals (10), a communication history (20) indicating communication related to a similar attack. Herein, the communication history (20) includes positional information about the mobile terminal (10). The information processing apparatus (2000) generates attack information related to an attack on the mobile terminal (10) by using positional information indicated by each of the extracted communication histories (20), and outputs the generated attack information.

Abstract: A first information processing apparatus (2000) determines an alternative representation (20) of an event sequence represented by a plurality of event histories (12), by use of dictionary data (30). The first information processing apparatus (2000) outputs information including the determined alternative representation (20). The dictionary data (30) indicate an event sequence and an alternative representation (20) relating to the event sequence in association with each other.

Abstract: An information processing apparatus generates a graph that represents an action of a program. On the graph, an edge represents action contents of a process in an event. Further, two nodes connected by the edge respectively represent a subject and an object of the event. The information processing apparatus outputs the generated graph. Further, the information processing apparatus also alters the generated graph. When an index value of an event satisfies a first predetermined condition which index value is based on the number of occurrences or the frequency of occurrences of the event, the information processing apparatus alters the graph with respect to an edge representing the event.
