  • Patent number: 11184392
    Abstract: Attempts at lateral movement are detected by monitoring failed login attempts across a number of endpoints in a network. By configuring endpoints across the network to report unsuccessful login attempts and monitoring these login attempts at a central location, patterns of attempts and failures may advantageously be detected and used to identify malicious attempts at lateral movement within the network before any unauthorized lateral movement is achieved.

  • Patent number: 11159568
    Abstract: Methods, systems, and media are shown for reducing the vulnerability of user accounts to attack that involve creating a rule for a user account that includes a permitted parameter corresponding to a user account activity property, monitoring the account activity of the user account. If it is determined that account activity property is inconsistent with the permitted parameter, then the user account is disabled. An example of a permitted parameter is a permitted time period, such as a start time, an end time, a recurrence definition, a days of the week definition, a start date, an end date, and a number of occurrences definition. Other examples are a physical parameter, such as a permitted geographic location, device, or network, or a permitted usage parameter, such as a permitted application, data access, or domain.

  • Patent number: 11151263
    Abstract: A system or method for encryption of data includes a light source, a random optical element and a light detection element. The light source is arranged to transmit an input data signal to the random optical element. The light source is incident on the random optical element such that the input data signal is randomly scattered by the random optical element to generate an image at on the detector disposed at an output of the random optical element. The image received by the detector is applied to a compressive sensing algorithm to generate a transfer function. The transfer function defines a relationship between the input data signal and the image to enable estimation and reconstruction of the input data signal.

  • Patent number: 11146538
    Abstract: Requests are pre-generated to include a cryptographic key to be used in fulfilling the requests. The requests may be encoded in uniform resource locators and may include authentication information to enable a service provider to whom the requests are submitted to determine whether the requests are authorized. The requests may be passed to various entities who can then submit the requests to the service provider. The service provider, upon receipt of a request, can verify the authentication information and fulfill the request using a cryptographic key encoded in the request.

  • Patent number: 11134073
    Abstract: In one embodiment, a device obtains certificate information for a plurality of network addresses. The device constructs, based on the certificate information, a bipartite graph that maps nodes representing common names from the certificate information to nodes representing autonomous systems. The device determines edge counts from the bipartite graph for the nodes representing the autonomous systems. The device identifies, based on the edge counts, a particular one of the common names as botnet-related by comparing edge counts for the autonomous systems associated with that particular common name to edge counts for the autonomous systems associated with one or more of the other common names.

  • Patent number: 11134376
    Abstract: A 5G user equipment (UE) can register for 5G services with a telecommunication network in part using a Subscription Concealed Identifier (SUCI), an encrypted version of a subscriber identifier, so that the actual subscriber identifier is not exposed during network registration. Legacy SIMs originally deployed for 4G/LTE and other legacy wireless access technologies store an international mobile subscriber identity (IMSI), but do not store a network public key needed to generate a SUCI. However, a 5G UE can still use a legacy SIM to securely obtain 5G services by encrypting the IMSI from the legacy SIM using a network public key stored in the 5G UE's own memory to generate a SUCI, and then transmitting the generated SUCI to the telecommunication network during network registration. Accordingly, the IMSI on the legacy SIM is not exposed during network registration.

  • Patent number: 11126740
    Abstract: An application running in a container is able to access files stored on disk via normal file system calls, but in a manner that remains isolated from applications and processes in other containers. In one aspect, a namespace virtualization component is coupled with a copy-on-write component. When an isolated application is accessing a file stored on disk in a read-only manner, the namespace virtualization component and copy-on-write component grant access to the file. But, if the application requests to modify the file, the copy-on-write component intercepts the I/O and effectively creates a copy of the file in a different storage location on disk. The namespace virtualization component is then responsible for hiding the true location of the copy of the file, via namespace mapping.

  • Patent number: 11113422
    Abstract: Systems, apparatuses, and methods related to a computer system having a processor and a main memory storing scrambled data are described. The processor may have a cache, a register, an execution unit, and an unscrambler. The processor can load the scrambled data into the cache; and the unscrambler may convert the scrambled data into unscrambled data just in time for the register or the execution unit during instruction execution. The unscrambled data can be an instruction, an address, or an operand of an instruction. Unscrambling can be performed just before loading the data item in a scrambled form from the cache into the register in an unscrambled form, or after the data item leaves the register in the scrambled form as input to the execution unit in the unscrambled form. The unscrambled data and the scrambled data may have the same set of bits arranged in different orders.

  • Patent number: 11108803
    Abstract: A security system scans application programming interfaces (APIs) to detect security vulnerabilities by receiving API documentation from a third-party system associated with the API and organizing it in an API specification that describes the hostname of the API and one or more endpoints of the API. For each of the endpoints, the API specification includes a uniform resource identifier, a method term, an input content type, an output content type (if applicable), authorization details, and any associated parameters or arguments. The security system performs an audit job for each combination of endpoints, potential security vulnerabilities, and (in some embodiments) authentication flows. In some embodiments, the security system is able to access portions of the API requiring authentication by using authentication flows received from the third-party system and detect security vulnerabilities related to authentication by manipulating the authentication units that make up the authentication flow.

  • Patent number: 11100241
    Abstract: To prevent ransomware from encrypting data elements stored in a memory of a computer-based system, the system identifies at least one identifier associated with a data element. The identifiers indicate an attribute(s) of the corresponding data element within the memory. The system then determines an optimal number of virtual traps for the data elements respective of at least one identifier. The system then determines an optimal position for each virtual trap corresponding to the at least one identifier. The system then positions the virtual traps at the determined position within the memory. The system monitors the data elements stored in the memory in order to identify whether changes have occurred, and determines respectively updated optimal number and positions of virtual traps.
