Systems and methods for detecting fraudulent system activity

A server computer comprising:

• a processor;
• and
• a computer-readable medium coupled with the processor, the computer-readable medium comprising instructions stored thereon that are executable by the processor to cause a computing device to perform operations comprising:
• generating intelligence data related to at least one of a group comprising:
• Internet Protocol (IP) addresses, email addresses, domain names, commercial mail receiving agencies, device identifiers, and user system activity;
• storing the intelligence data;
• receiving a registration request message from a user via a computing device, the registration request message comprising identifying information for the user, and identifying information for the computing device;
• analyzing the registration request message to determine whether the identifying information for the user and the identifying information for the computing device is associated with any data included in the intelligence data;
• and
• sending a registration response message indicating whether or not the user is registered, based on the result of analyzing the registration request message to determine whether the identifying information for the user and the identifying information for the computing device is associated with any data included in the intelligence data.

A non-transitory computer-readable medium comprising instructions stored thereon that are executable by at least one processor to cause a computing device to perform operations comprising:

• generating intelligence data related to at least one of a group comprising:
• Internet Protocol (IP) addresses, email addresses, domain names, commercial mail receiving agencies, device identifiers, and user system activity;
• storing the intelligence data;
• receiving a registration request message from a user via a computing device, the registration request message comprising identifying information for the user, and identifying information for the computing device;
• analyzing the registration request message to determine whether the identifying information for the user and the identifying information for the computing device is associated with any data included in the intelligence data;
• and
• sending a registration response message indicating whether or not the user is registered, based on the result of analyzing the registration request message to determine whether the identifying information for the user and the identifying information for the computing device is associated with any data included in the intelligence data.
