Method and a system for identifying compromised devices in an application infrastructure

A computer-implemented method for identifying compromised user devices in an application infrastructure associated with an application family, the method being executable by a given user device of the application infrastructure, executing a given application thereof, the method comprising:

• in response to a first initiation of the given application on the given user device, determining whether at least one other application of the application family is executed on the given user device;
• in response to failing to identify the at least one other application of the application infrastructure executed on the given user device, generating a data container having a null value for transmission thereof to a server associated with the given application, thereby causing the server to:
• receive the data container;
• generate a unique identifier for the given user device;
• and
• transmit an updated data container having the unique identifier to the given user device for storing the updated data container in service data of the given application;
• in response to identifying the at least one other application of the application infrastructure executed on the given user device:
• retrieving, from the service data of the at least one other application, an application data container for transmission thereof to the server associated with the given application, thereby causing the server to:
• receive the application data container;
• update the application data container, thereby generating an updated application data container;
• and
• transmitting the updated application data container to the given user device for storing the updated application data container in the service data of the given application;
• in response to any subsequent initiation of the given application on the given user device:
• transmitting a then current data container having a then current value of the unique identifier of the given user device to the server associated with the given application, thereby causing the server to:
• receive the then current data container;
• update the then current value of the unique identifier of the given user device, thereby generating a then updated value of the unique identifier;
• and
• transmit a then updated data container having the then updated value of the unique identifier to the user device for storing the then updated data container in the service data of the given application.

A server for identifying compromised user devices in an application infrastructure associated with an application family, the server being associated with a given application of the application family, the server comprising at least one processor and at least one non-transitory computer-readable memory storing executable instructions, which, when executed by the at least one processor, cause the server to:

• in response to receiving, from a given user device executing the given application, a data container having a null value, the data container having the null being indicative of a first initiation of the given application on the given electronic device:
• generate a unique identifier, having an initial predetermined value, for the given user device;
• store the unique identifier of the given user device in a database of the server;
• in response to receiving, from the given user device, an other data container including the unique identifier of the given user device having a then current value, the then current value being indicative of a respective initiation of the given application on the given user device, the then current value being indicative of all applications of the application family executed on the given user device:
• update the then current value of the unique identifier of the given user device in the database, thereby generating an updated value of the unique identifier;
• and
• transmit an updated container with the updated value of the unique identifier to the given user device;
• in response to receiving information indicative of the given user device being compromised:
• generate, for a subsequent initiation of the given application on the given user device, a then updated value of the unique identifier, indicative of the given user device being compromised;
• and
• transmit a then updated data container with the then updated value of the unique identifier to the given user device, thereby enabling other servers of the application infrastructure, associated with other applications of the application family, to identify the given user device as being compromised and take remedial actions.

An electronic device for identifying compromised user devices in an application infrastructure associated with an application family, the electronic device executing a given application of the application family, the electronic device comprising at least one processor and at least one non-transitory computer-readable memory storing executable instructions, which, when executed by the at least one processor, cause the electronic device to:

• in response to a first initiation of the given application on the given user device, determine whether at least one other application of the application family is executed on the given user device;
• in response to failing to identify the at least one other application of the application infrastructure executed on the given user device, generate a data container having a null value for transmission thereof to a server associated with the given application, thereby causing the server to:
• receive the data container;
• generate a unique identifier for the given user device;
• and
• transmit an updated data container having the unique identifier to the given user device for storing the updated data container in service data of the given application;
• in response to identifying the at least one other application of the application infrastructure executed on the given user device:
• retrieve, from the service data of the at least one other application, an application data container for transmission thereof to the server associated with the given application, thereby causing the server to:
• receive the application data container;
• update the application data container, thereby generating an updated application data container;
• and
• transmitting the updated application data container to the given user device for storing the updated application data container in the service data of the given application;
• in response to any subsequent initiation of the given application on the given user device:
• transmit a then current data container having a then current value of the unique identifier of the given user device to the server associated with the given application, thereby causing the server to:
• receive the then current data container;
• update the then current value of the unique identifier of the given user device, thereby generating a then updated value of the unique identifier, and
• transmit a then updated data container having the then updated value of the unique identifier to the user device for storing the then updated data container in the service data of the given application.
