摘要： Some embodiments use text and/or image processing methods to determine whether a child is transmitting confidential information to a conversation partner via an electronic messaging service. Some embodiments detect whether an image transmitted as part of an electronic message shows a bank card, a social security card, or an identity document, among others. When detecting such a situation, some embodiments automatically send a notification to a third party (e.g., parent, teacher, etc.)

摘要： In some embodiments, a behavioral computer security system protects clients and networks against threats such as malicious software and intrusion. A set of client profiles is constructed according to a training corpus of events occurring on clients, wherein each client profile represents a subset of protected machines, and each client profile is indicative of a normal or baseline pattern of using the machines assigned to the client respective profile. A client profile may group together machines having a similar event statistic. Following training, events detected on a client are selectively analyzed against a client profile associated with the respective client, to detect anomalous behavior. In some embodiments, individual events are analyzed in the context of other events, using a multi-dimensional event embedding space.

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： 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.

摘要： Described systems and methods allow conducting computer security operations, such as detecting malware and spyware, in a bare-metal computer system. In some embodiments, a first processor of a computer system executes the code samples under assessment, whereas a second, distinct processor is used to carry out the assessment and to control various hardware components involved in the assessment. Such hardware components include, among others, a memory shadower configured to detect changes to a memory connected to the first processor, and a storage shadower configured to detect an attempt to write to a non-volatile storage device of the computer system. The memory shadower and storage shadower may be used to inject a security agent into the computer system.

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 an automatic device detection/discovery, particularly of ‘Internet of Things’ client devices such as wearables, mobile communication devices, and smart home appliances, among others. Device detection comprises assigning a target device to a device category, such as “tablet computer from an unknown manufacturer, running Android®”. Some embodiments determine multiple preliminary category assignments according to distinct inputs such as HTTP user agent data, DHCP data, mDNS data, and MAC data. Each preliminary category assignment may come with an associated score. A definitive category assignment may be made according to an aggregate score. Applications include computer security, software provisioning, and remote device management, among others.

摘要： Described systems and methods enable protecting multiple client systems (e.g., a corporate network) from computer security threats such as malicious software and intrusion. In some embodiments, each protected client operates a live introspection engine and an on-demand introspection engine. The live introspection engine detects the occurrence of certain events within a protected virtual machine exposed on the respective client system, and communicates the occurrence to a remote security server. In turn, the server may request a forensic analysis of the event from the client system, by indicating a forensic tool to be executed by the client. Forensic tools may be stored in a central repository accessible to the client. In response to receiving the analysis request, the on-demand introspection engine may retrieve and execute the forensic tool, and communicate a result of the forensic analysis to the security server. The server may use the information to determine whether the respective client is under attack by malicious software or an intruder.

摘要： Described systems and methods enable an efficient analysis of security-relevant events, especially in hardware virtualization platforms. In some embodiments, a notification handler detects the occurrence of an event within a virtual machine, and communicates the respective event to security software. The security software then attempts to match the respective event to a collection of behavioral and exception signatures. An exception comprises a set of conditions which, when satisfied by an tuple, indicates that the respective entity is not malicious. In some embodiments, a part of exception matching is performed synchronously (i.e., while execution of the entity that triggered the respective event is suspended), while another part of exception matching is performed asynchronously (i.e., after the triggering entity is allowed to resume execution).
