Abstract
A device and method to accurately detect list-based attacks without reducing the convenience for authorized users. An acquirer acquires information on accounts used for log-in trials to a plurality of websites. An analyzer calculates the degree of use of each account used in common for log-in trials to different websites in a predetermined period of time out of the accounts acquired by the acquirer and determine the log-in trials using the account to be attacks when the degree of use exceeds a predetermined threshold. A detector detects, as an attack, a log-in trial to the website using the same account as the account used for the log-in trials determined to be attacks by the analyzer.
