Implementations include a computer-implemented method comprising: obtaining data representing observed conditions in an enterprise network, each observed condition being associated with at least one cybersecurity issue, a cybersecurity issue comprising one of (i) a vulnerability comprising an instance of a vulnerable condition or (ii) a weakness that is likely to cause a vulnerability to occur; using a plurality of exploitation prediction models to determine probabilities of exploitation of the cybersecurity issues associated with the observed conditions in the enterprise network, wherein the plurality of exploitation prediction models are trained using a knowledge mesh generated using data from cybersecurity repositories; assigning a priority ranking to each of the observed conditions in the enterprise network based on the respective probabilities of exploitation for the cybersecurity issues associated with the observed conditions; and performing one or more actions to mitigate the observed conditions in the enterprise network based on the priority rankings.

Automated cybersecurity vulnerability prioritization

Methods, systems, and apparatus for enhancing cryptographic hash digests. In one aspect, a method includes obtaining a hash digest that represents a data input. Symbols in the hash digest are divided into a number of groups of equal size. Each group is mapped to a respective point on a Bloch sphere. A quantum system comprising multiple qubits is initialized by initializing each qubit of the multiple qubits in a quantum state specified by a respective point on the Bloch sphere. An expectation value of the initialized quantum system is computed to obtain a quantum fingerprint for the data input.

Enhanced cryptographic hash digests using quantum computing

In some implementations, a user device may transmit, to a first data source, a first message encoding a first query and may receive a first response to the first query from the first data source. The user device may transmit, to a second data source, a second message encoding a second query that duplicates the first query and may receive a second response to the second query from the second data source. The user device may transmit a first reverse query to the first data source based on the second response and/or a second reverse query to the second data source based on the first response. The user device may receive at least one reverse query response. Accordingly, the user device may determine whether an answer to the first query is valid, based on the first response, the second response, and the at least one reverse query response.

Data integrity validation using diversified queries across multiple sources, interfaces, and networks

A device may receive a machine learning model, training data, a pipeline configuration for the machine learning model, and impact costs associated with customer preferences, and may perform assessments of the machine learning model to identify attacks associated with the machine learning model and vulnerabilities associated with the attacks. The device may map the vulnerabilities to threats, may map the threats to the impact costs, and may determine success rates of the threats. The device may calculate probabilities of the threats based on the vulnerabilities and the success rates, and may calculate risk costs of the attacks based on the probabilities and the impact costs. The device may identify controls for limiting the vulnerabilities and control costs. The device may determine a total cost for eliminating the risk costs based on the risk costs and the control costs, and may perform actions based on the total cost.

A first device may provide a request to establish a secure communication with a second device, and may hide public keys based on a commutative legacy compatible encryption process sharing a modulus and based on quasi-Carmichael numbers larger than the modulus with quadratic residuals. The first device may utilize variable extendable-output function hashing, based on the modulus, with bloom filtering to generate an output that prevents creation of classical rainbow tables, and may utilize a key derivation function to generate a symmetric key based on the output. The first device may establish the secure communication with the second device based on the symmetric key.
