摘要： Described systems and methods allow protecting multiple wireless Internet-of-things (IoT) devices against impersonation attacks. In some embodiments, a security appliance detects an availability notification (e.g., a Bluetooth® Low Energy advertisement) emitted as part of a protocol of establishing a wireless connection between two devices. The security appliance may then determine whether the detected notification fits a baseline notification pattern of the apparent sender. When no, the security appliance may attack the sender device by replying to the respective availability notification and initiating a handshake.

摘要： Described systems and methods protect client devices such as personal computers and IoT devices against malicious software. In some embodiments, a plurality of client devices report the occurrence of various events to a security server, each such event caused by a local instance of a target application (e.g., mobile app) executing on a respective device. The security server then collates the behavior of the respective target application across the plurality of client devices. Some embodiments compute an aggregate event set and/or sequence combining events detected on one device with events detected on other devices, and determine whether the target application is malicious according to the aggregate event set/sequence.

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. When introduced to the local network, some embodiments of network regulator take over some network services from a router, and automatically install the network regulator as gateway to the local network. The network regulator then carries out an automatic device discovery procedure and distribute device-specific utility agents to the protected client systems. An exemplary utility agent detects when its host device has left the local network, and in response, sets up a virtual private network (VPN) tunnel with a security server to maintain protection of the respective device.

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.
