A computer system is provided. The computer system includes a memory and at least one processor coupled to the memory and configured to detect a request for a sign-up form from a client device to a remote server. The at least one processor is further configured to generate a code module based on the detection. The code module is configured to request a credential vulnerability check from an application management server. The at least one processor is further configured to provide the code module to the client device for execution on the client device in response to an attempted submission of the sign-up form. The at least one processor is further configured to receive a result of the credential vulnerability check from the client device and perform a security action in response to the credential vulnerability check indicating vulnerable credentials.

Systems and methods for dynamic detection of vulnerable credentials

Described embodiments provide systems and methods for preventing unauthorized access of information from a resource. A device intermediary between a client and a server in a session can receive a first request from the client that includes a first uniform resource locator (URL) of the server. The device may receive a response from the server that includes a second URL. The device may update the response by including a client identifier for the session in a set-cookie field, obfuscating the second URL into a string, and replacing the second URL in the response with the string. The device may receive a second request that includes a candidate client identifier, and a third URL. The device may determine whether the second request is valid, by at least one of: matching the candidate client identifier with the client identifier, and determining whether the second URL is recoverable using the third URL.

Systems and methods to detect and prevent bots from random access by randomized HTTP URLs in real time in distributed systems

Described embodiments provide systems and methods for detecting autonomous programs is provided. A device, intermediary to a plurality of clients and a plurality of servers, can receive a first request from a first client of the plurality of clients to a server of the plurality of servers via a connection between the device and the first client. The device can include, into a response from the server to the first client, a uniform resource locator (URL) comprising one or more randomly generated characters within a predetermined character space. The device can determine that the first client has an autonomous program responsive to receiving a second request from the first client using the URL. The device can terminate, responsive to the determination, the connection to the first client.

Generating URLs to detect autonomous programs systems and methods

Described embodiments provide systems and methods performing header protection. A device can receive from a client, a request relating to a first resource, for a second resource. The device can determine, using an identifier for the session, whether an address of the first resource has been previously accessed by the client during the session. The device can verify, using an address of the second resource, whether the address of the second resource is mapped to the address of the first resource for the session between the client and the device. The device can determine whether to provide access to the second resource responsive to the address of the first resource being previously accessed by the client during the session and the address of the second resource being mapped to the address of the first resource for the session.

Systems and methods for performing header protection in distributed systems

A computer system is provided. The computer system includes a memory, a network interface, and a processor coupled to the memory and the network interface. The processor is configured to receive a response to a request to verify whether an ostensible client of a service is actually a client or a bot, the response including an indicator of whether the ostensible client is a client or a bot; receive information descriptive of interoperations between the ostensible client and the service that are indicative of whether the ostensible client is a client or a bot; and train a plurality of machine learning classifiers using the information and the indicator to generate a next generation of the plurality of machine learning classifiers.

Adaptive anomaly detector

Systems and methods for autonomous program management include a device which receives a request from a client responsive to execution of a script on the client. The request may include a location corresponding to the script and an identifier. The device may determine that activity of the client is activity of an autonomous program based on a comparison of the location to a reference being generated by the device for the client and determined using the identifier from the request. The device may block a subsequent request from the client to a server responsive to the determination.

Systems and methods for autonomous program detection

Described embodiments provide systems and methods for learning across multiple application delivery controllers and updating settings across the application delivery controllers. A profile can be generated based on selection of a set of intermediary devices managed by a device. The set of intermediary devices configured to load balance data of an application hosted in different computing environments. Activity can be identified at the intermediary devices with use of a firewall. The activity having an appearance of a malicious attack on at least one intermediary device of the set. The device can determine if the activity is permissible or a violation based on a comparison of an aggregation of data records for the identified activity and a threshold. The device can provide a notification to at least one intermediary device of the set to configure the at least one intermediary device to allow the activity or prevent the activity.

Controlling application delivery based on a profile and threshold

Systems and methods for autonomous program management include a device which may transmit data to a client in response to a first request from the client. The data may include a response to the first request and a copy of data available to the device corresponding to the first request or the client. The device may receive a second request including the copy of data from the client. The device may determine that the second request is from an autonomous program rather than a user of the client based on the copy of data from the second request. The device may block at least one subsequent request from the client in response to the determination that the second request is from an autonomous program.

Systems and methods for protection against session stealing is described. In embodiments of the present solution, a device intermediary to the client and the server may identify first properties of the client and associate the first properties with the session key. When the device receives subsequent request comprising the session key, the device matches the associated first properties with second properties of the second device that is sending the subsequent request. If there is a match, the subsequent request transmitted to the server. Otherwise, the subsequent request is rejected.
