Abstract: A computing device comprising a secure browser extension for a web browser monitors for satisfaction of one or more operating conditions to identify whether one or more unauthorized applications are intercepting web browser communications. Based on satisfaction of at least one operating condition, the secure browser extension of the computing device sends an HTTPS request to a known service via the web browser. The secure browser extension receives an HTTPS response to the HTTPS request via the web browser. The secure browser extension determines whether the certificate included in the HTTPS response is trusted by the secure browser extension. Based on determining the certificate is not trusted, the secure browser extension terminates the web browser session and generates a notification for display at the computing device that indicates web browser communications are compromised.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a checkout system executable code monitoring, and user account compromise determination system. The system monitors executable code initiating and executing on checkout systems, including determining hashes of the executable code. The system determines whether the executable code is malicious based on the hash, and associated information of the executable code. Additionally, the system monitors user access to checkout systems, and determines user accounts associated with being compromised. User interfaces are generated describing checkout systems associated with a risk of being compromised, and are configured for user interaction, which cause generation of updated user interfaces and access to electronic data stores to determine information relevant to the user interaction.

Abstract: Aspects of the present disclosure relate to a machine determining a quality ranking of a subject. The machine accesses a current input representing answers to a plurality of questions about the subject, each answer representing a ranking of a quality of the subject at a specified time, where the subject has a geographic location. The machine determines, based on the current input, an overall ranking of the quality of the subject. The machine determines, based on the current input and based on one or more of input received about the subject at a time different from the specified time and input about other subjects proximate to the geographic location, a future ranking of the quality of the subject. The machine transmits a graphical output corresponding to the overall ranking and the determined future ranking of the quality of the subject.
