Patent attributes
Methods and systems for fictitious account generation on detection of account takeover conditions are described. A login attempt may be detected and determined to indicate fraud, such as when the login attempt is accompanied by many failed login attempts or is from an untrusted or known malicious endpoint. A fictitious account may be generated, which may include falsified account data and may limit account functionality to prevent unauthorized and fraudulent use of the account. The computing device that performs the login attempt may be routed and permitted to log in to the fictitious account, where the service provider or another computing entity may then monitor activity and usage of the fictitious account by the potentially malicious party. The fictitious account may be maintained so that other actors using the account may access the account and their activity also monitored.
