Complaint-reported loss is money victims say they lost when submitting complaints to a particular reporting system. It describes the reports collected under that system’s rules and scope; it is not a complete measure of all cybercrime losses or a global economic total.
In cyber-security analysis, this figure can help show the reported financial impact of crimes such as online fraud. But reporting rates, definitions, and coverage affect the total, and it should not be treated as a count of breaches or direct validation of a worldwide damage forecast. Defenders and analysts should compare it only with data that measures similar losses over a comparable period.
