Abstract: Apparatuses, systems, and techniques for classifying a candidate uniform resource locator (URL) as malicious using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface. The integrated circuit hosts a hardware-accelerated security service to protect one or more computer programs executed by the host device. The security service extracts a set of features from data stored in the physical memory, the data being words in a candidate URL and numeric features of a URL structure of the candidate URL. The security service classifies, using the ML detection system, the candidate URL as malicious or benign using the set of features. The security service outputs an indication of a malicious URL responsive to the candidate URL being classified as malicious.

Abstract: The technology disclosed herein enables an auxiliary device to run a service that can access and analyze data of a Trusted Execution Environment (TEE). The auxiliary device may establish an auxiliary TEE in the auxiliary device and establish a trusted communication link between the auxiliary TEE and the TEE (i.e., primary TEE). The primary TEE may execute a target program using the primary devices of a host device (e.g., CPU) and the auxiliary TEE may execute a security program using the auxiliary device (e.g., DPU). In one example, the primary and auxiliary TEEs may be established for a cloud consumer and the auxiliary TEE may execute a security service that can monitor data of the primary TEE even though the data is inaccessible to all other software executing external to the primary TEE (e.g., inaccessible to host operating system and hypervisor).

Abstract: Apparatuses, systems, and techniques for classifying one or more candidate uniform resource locators (URLs) as having a domain generation algorithm (DGA) domain using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface.

The security service classifies, using the ML detection system, the one or more candidate URLs as having a DGA domain or a non-DGA domain using the set of features. The security service outputs an indication of a DGA malware responsive to the one or more candidate URLs being classified as having the DGA domain.

Abstract: Apparatuses, systems, and techniques for detecting that one or more computer programs executed by a host device are subject to malicious activity using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface.

The security service determines, using the ML detection system, whether the one or more computer programs are subject to malicious activity based on the set of features. The security service outputs an indication of the malicious activity responsive to a determination that the one or more computer programs are subject to the malicious activity.

Abstract: Apparatuses, systems, and techniques for classifying one or more computer programs executed by a host device as being ransomware using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface. The integrated circuit hosts a hardware-accelerated security service to protect one or more computer programs executed by the host device. The security service obtains a series of snapshots of data stored in the physical memory and extracts a set of features from each snapshot of the series of snapshots, each snapshot representing the data at a point in time. The security service classifies a process of the one or more computer programs as ransomware or non-ransomware using the set of features and outputs an indication of ransomware responsive to the process being classified as ransomware.

Execution telemetry may include data regarding or describing the execution of the process, or describing hardware used to execute the process, such as processor temperature, memory usage, etc.

Abstract: A wind turbine, including a main gear box, which is lubricated and/or cooled by oil, and a thermosiphon cooling system for cooling the oil is provided. The thermosiphon cooling system solves the main challenges facing the oil cooling systems in wind turbines. The high efficiency of the evaporation heat transfer mechanism gives the capacity to transfer the required heat load in relatively smaller size system. In this way, installation space is reduced. The thermosiphon cooling system has no service requirements over the lifetime of the wind turbine since the thermosiphon cooling system has no moving parts. Costs are saved since the simplicity of the thermosiphon cooling system adds a big value to the system business case.

Abstract: Optimizing power generation from waste heat in large industrial facilities such as petroleum refineries by utilizing a subset of all available hot source streams selected based, in part, on considerations for example, capital cost, ease of operation, economics of scale power generation, a number of ORC machines to be operated, operating conditions of each ORC machine, combinations of them, or other considerations are described. Recognizing that several subsets of hot sources can be identified from among the available hot sources in a large petroleum refinery, subsets of hot sources that are optimized to provide waste heat to one or more ORC machines for power generation are also described.

Abstract: Disclosed is a method and system for compensating for excessive attenuation on an RF connection between a remote radio head (RRH) and an antenna of cell site. In an example configuration, in which first and second RF carriers of a cell site traverse different RF paths between respective RRHs and respective antenna, the second RF carrier may be subject to more attenuation than the first. Consequently, antenna transmission power of the second RF carrier may be below one or another threshold. For communication services to user equipment devices that involve both the first and second RF carriers, the diminished antenna transmission power of the second RF carrier may cause service degradation. In accordance with example embodiments, a controlling network entity may determine that the power is diminished, and responsively reallocate transmission power from an underutilized carrier to the second carrier, thereby boosting its transmission power and remediating service degradation.
