Abstract: Blockchain systems operate over a network of computing devices. Proof of space blockchain consensus systems utilize data stored in storage devices across the computing devices within the network. These storage devices are utilized to generate and store proof of space consensus data. This data is then accessed at a later time to respond to challenges issued across the blockchain network. In order to limit successful submissions of these challenge responses, one or more filters are utilized. These filters result in only a fraction of the stored data on a storage device to be useable for solving the blockchain challenge. Attackers may attempt to circumvent this filter to increase their odds of submitting an approved solution to the blockchain challenge. In order to address this, additional data structures are stored within the storage device and are registered at the time of creation on the blockchain to make these filters more robust.

Abstract: A system for detecting Denial-of-Service (DoS) attacks on one or more user profiles collects a number of invalid sign-on attempts on the one or more user profiles during every time interval. The system determines a number of invalid sign-on attempts on every user profile since the start of the first time interval. The system detects a first DoS attack on a particular user profile if a first number of invalid sign-on attempts on the particular user profile exceeds a single-user profile. The system detects a second DoS attack on multiple user profiles during the first time interval if the increase in the total number of invalid sign-on attempts since the last time interval exceeds a scan-level threshold number. The system detects a third DoS attack on multiple user profiles if the total number of invalid sign-on attempts detected during combined time intervals exceeds a third threshold number.

Abstract: Methods and systems are described herein for a transfer authorization system that may monitor for transfer requests for secondary cryptographic addresses maintained for one or more primary cryptographic addresses. When a transfer request is received, the transfer authorization system may determine that the transfer request is for a secondary cryptographic address. Based on that determination, the transfer authorization system may determine that the source cryptographic address of the request is authorized to receive control of cryptographic tokens from the secondary cryptographic address and that the request is associated with the source cryptographic address. The transfer authorization system may then transfer control of one or more cryptographic tokens from an associated primary cryptographic address to the secondary cryptographic address, and upon the successful transfer, may also transfer control of the one or more tokens to the requestor.

Abstract: A system for providing forensic tracing of memory device content erasure and tampering is disclosed. The system uses a special command that enables forensic tracing in a secure memory device. Once the forensic tracing is enabled, firmware of the memory device tracks the data stored on the memory device. The command specifies whether the tracking and tracing is for the entire memory device or for a region of the memory device. The firmware confirms that the forensic tracing is enabled, and a target protection region is defined. Once an authenticated command for an operation to access, modify, or erase data of the memory device is received from a host, the system enables the operation to proceed. The system creates a trace of the operation and the metadata of the target region that is modified within a secure memory region of the memory device that is not addressable by the host device.

Abstract: A client application sends DNS requests to a threat protection service when a mobile device operating the client application is operating off-network. The application is configured to detect network conditions and automatically configure an appropriate system-wide DNS resolution setting. Preferably, DNS requests from the client identify the customer and the device to threat protection (TP) service resolvers without introducing a publicly-visible customer or device identifier to the DNS requests or responses. The TP system then applies the correct policy to DNS requests coming from off-network clients. In particular, the resolver recognizes the customer for requests coming for off net clients and apply the customer's policy to such request. The resolver is configured to log the customer and the device associated with requests from the TP off-net client. Request logs from the TP resolver are provided to a cloud security intelligence platform for threat intelligence analytics and customer visible reporting.

Abstract: An anomaly detection system is disclosed capable of reporting anomalous processes or hosts in a computer network using machine learning models trained using unsupervised training techniques. In embodiments, the system assigns observed processes to a set of process categories based on the file system path of the program executed by the process. The system extracts a feature vector for each process or host from the observation records and applies the machine learning models to the feature vectors to determine an outlier metric each process or host. The processes or hosts with the highest outlier metrics are reported as detected anomalies to be further examined by security analysts. In embodiments, the machine learnings models may be periodically retrained based on new observation records using unsupervised machine learning techniques. Accordingly, the system allows the models to learn from newly observed data without requiring the new data to be manually labeled by humans.
