Abstract: Systems and methods for implementing a secure communication channel between kernel and user mode components are provided. According to an embodiment, a shared memory is provided through which a kernel mode process and a user mode process communicate. The kernel mode process is assigned read-write access to the shared memory. The user mode process is assigned read-only access to the shared memory. An offset-based linked list is implemented within the shared memory. Kernel-to-user messages are communicated from the kernel mode process to the user mode process by adding corresponding nodes to the offset-based linked list. One or more kernel-to-user messages are read by the user mode process following the offset-based linked list in order. The kernel mode process is signaled by the user mode process that a kernel-to-user message has been consumed by the user mode process through an input output control (ioctl) system call or an event object.

Abstract: Systems and methods for improving malware detection by a sandbox service by utilizing Endpoint Detection and Response (EDR) origin contextual information are provided. According to an embodiment, a sandbox service associated with a network security platform protecting an enterprise network receives a file associated with sandbox-evading malware, to be classified by the sandbox service, and contextual information related to the file. The file is received from an endpoint security solution of the network security platform running on an endpoint device of the enterprise network. The sandbox service classifies the file as being malware by detonating the sandbox-evading malware as a result of performing sandboxing on the file including emulating an environment of the endpoint device based on the contextual information.

Abstract: Systems and methods are described for synergistically combining static file based detection and behavioral analysis to improve both threat detection time and accuracy. An endpoint security solution running on an endpoint device generates a static analysis score by performing a static file analysis on files associated with a process initiated on the endpoint device. When the static analysis score meets or exceeds a static analysis threshold, then a network security platform treats the process as malicious and blocks execution of the process. When the static analysis score is less than the static analysis threshold, then the endpoint security solution obtains a dynamic analysis score for the process. The network security platform treats the process as malicious and causes execution of the process to be blocked based on a function of the static analysis score and the dynamic analysis score.

Abstract: Systems and methods for performing multi-feed classification of security events to facilitate automated IR orchestration are provided. According to one embodiment a cloud-based security service protecting a private network provides a plurality of data feeds, wherein each data feed of the plurality of data feeds independently classify a given security event and produce a classification result. In response to an event associated with a process of an endpoint device that is part of the private network an endpoint protection platform running on the endpoint device performs an initial classification of the event and transmits the classification result to the cloud-based security service for final classification to facilitate causing, by the cloud-based security service, the endpoint protection platform to perform an automated incident response, by providing an output of an automated response engine of the cloud-based security service to the endpoint protection platform.

Abstract: Systems and methods for mitigating the impact of malware by reversing malware related modifications in a computing device are provided. According to an embodiment, a sandbox service running within a network security platform protecting an enterprise network receives a file containing malware and associated contextual information from an endpoint security solution running on an endpoint device, which has been infected by the malware. The sandbox service captures information regarding a first series of actions performed by the malware and based on the first series of actions generates a remediation script specifying a second series of actions that are configured to restore the endpoint device to a pre-infected state. The network security platform causes the endpoint device to be returned to the pre-infected state by causing the endpoint security solution to execute the remediation script on the endpoint device.

Abstract: Systems and methods for improving security event classification by leveraging user-behavior analytics are provided. According to an embodiment, a UEBA-based security event classification service of a cloud-based security platform maintains information regarding historical user behavior of various users of an enterprise network. An endpoint protection platform running on an endpoint device that is part of the enterprise network performs an initial classification of the event, based on which the endpoint protection platform blocks activity by the process. The endpoint production platform requests input from the cloud-based security platform which causes the cloud-based security platform performs a reclassification of the event based on contextual information, multiple data feeds and the UEBA-based security event classification service.

Abstract: A computer implemented method for protecting data stored in at least one file from being overwritten by malicious code, comprises: monitoring at least one file stored in a storage device location to detect a request to perform an overwrite operation at least a portion of data of the at least one file; redirecting the overwrite operation to a memory location designated as safe for being overwritten; analyzing the overwrite operation at the memory location to identify an association with malicious code; and outputting an indication of an attempt to overwrite the at least one file by malicious code.

Abstract: According to one embodiment, a transparent security gateway is coupled between a client end station (CES) and a web application server (WAS). The security gateway monitors an encryption protocol handshake between the CES and the WAS to capture, using a provided private key of the WAS, a generated symmetric key to be used for an encryption layer connection. Using the captured symmetric key, the security gateway receives an encrypted connection record of the encryption layer connection, decrypts the encrypted connection record to yield a plaintext connection record, modifies the plaintext connection record, encrypts the modified plaintext connection record using the symmetric key, and transmits one or more packets carrying the encrypted modification plaintext connection record instead of the received encrypted connection record such that neither the CES or WAS is aware of the modification of the encrypted data.
