Systems and methods for account security are provided. In one example embodiment, a first login request including a username and a password is analyzed to identify a first internet protocol (IP) address and a first request time associated with the first login request. A login history comprising login request data for the server computer is analyzed to identify a plurality of usernames, wherein each username of the plurality of usernames is associated with a corresponding login request from the first IP address within a threshold time period of the first request time. In response to determining a login success ratio is below a threshold login success ratio and a number of unique usernames in the analyzed data is above the unique username threshold, the system automatically performs a security action.
