摘要： Described systems and methods enable a swift and efficient detection of fraudulent Internet domains, i.e., domains used to host or distribute fraudulent electronic documents such as fraudulent webpages and electronic messages. Some embodiments use a reverse IP analysis to select a set of fraud candidates from among a set of domains hosted at the same IP address as a known fraudulent domain. The candidate set is further filtered according to domain registration data. Online content hosted at each filtered candidate domain is further analyzed to identify truly fraudulent domains. A security module may then prevent users from accessing a content of such domains.

摘要： Some embodiments enable distributing data (e.g., recorded video, photographs, recorded audio, etc.) to a plurality of users in a manner which preserves the privacy of the respective users. Some embodiments leverage homomorphic encryption and proxy re-encryption techniques to manipulate the respective data so that selected portions of it are revealed according to an identity of the user currently accessing the respective data.

摘要： Some embodiments use text and/or image processing methods to determine whether a user of an electronic messaging platform is subject to an online threat such as cyberbullying, sexual grooming, and identity theft, among others. In some embodiments, a text content of electronic messages is automatically harvested and aggregated into conversations. Conversation data are then analyzed to extract various threat indicators. A result of a text analysis may be combined with a result of an analysis of an image transmitted as part of the respective conversation. When a threat is detected, some embodiments automatically send a notification to a third party (e.g., parent, teacher, etc.)

摘要： Described systems and methods allow an automatic translation from a natural language (e.g., English) into an artificial language such as a structured query language (SQL). In some embodiments, a translator module includes an encoder component and a decoder component, both components comprising recurrent neural networks. Training the translator module comprises two stages. A first stage trains the translator module to produce artificial language (AL) output when presented with an AL input. For instance, the translator is first trained to reproduce an AL input. A second stage of training comprises training the translator to produce AL output when presented with a natural language (NL) input.

摘要： In some embodiments, a network regulator device protects a local network of client systems (e.g. Internet-of-things devices such as smartphones, home appliances, wearables, etc.) against computer security threats. Various aspects of the operation of the network regulator may be managed remotely via a graphical user interface (GUI) executing on an administration device, such as a mobile phone. The GUI is further configured to display a security notification to a user of the administration device, the security notification indicating the occurrence of a security event caused by an action of a protected client system.

摘要： Described systems and methods allow protecting a computer system from malware such as viruses, worms, and spyware. A reputation manager executes on the computer system concurrently with an anti-malware engine. The reputation manager associates a dynamic reputation indicator to each executable entity seen as a unique combination of individual components (e.g., a main executable and a set of loaded libraries). The reputation indicator indicates a probability that the respective entity is malicious. The reputation of benign entities may increase in time. When an entity performs certain actions which may be indicative of malicious activity, the reputation of the respective entity may drop. The anti-malware engine uses an entity-specific protocol to scan and/or monitor each target entity for malice, the protocol varying according to the entity's reputation. Entities trusted to be non-malicious may be analyzed using a more relaxed protocol than unknown or untrusted entities.

摘要： Described systems and methods enable an efficient detection and analysis of software events, especially in hardware virtualization configurations. In some embodiments, certain types of events are analyzed asynchronously, in the sense that the triggering entity is allowed to continue execution while the respective event is added to a queue for later processing. Some embodiments modify the instruction set architecture of the processor by adding a processor instruction dedicated to delivering event notifications. Such notification instructions allow for complex and flexible event detection without some of the disadvantages of conventional methods such as hooking.

摘要： Described systems and methods enable a decryption of encrypted communication between a client system and a remote party, for applications such as detection and analysis of malicious software, intrusion detection, and surveillance, among others. The client system executes a virtual machine and an introspection engine outside the virtual machine. The introspection engine is configured to identify memory pages whose contents have changed between a first session event (e.g., a ServerHello message) and a second session event (e.g., a ClientFinished message). The respective memory pages are likely to contain encryption key material for the respective communication session. A decryption engine may then attempt to decrypt an encrypted payload of the respective communication session using information derived from the content of the identified memory pages.
