Systems and methods of mitigating leakage of credentials of a user of a computer network, including monitoring at least one data source to scrape data that is compatible with credential data, applying a machine learning algorithm to the scraped data to identify at least one potential leaked credential, wherein the at least one potential leaked credential is identified using at least one neural network, authenticating the identified at least one potential leaked credential by a database of valid credentials of the computer network, and replacing credentials corresponding to the at least one leaked credential.
