摘要： Certain embodiments herein relate to pairing an external device and a computer using a random user action. The random user action may be generated based on the type of device. After an external device is connected to the computer, the external device is segregated from one or more resources of the computer. A random user action based on the device type, and to be received from the external device, is generated and requested. If the random user action is received, the external device is paired with the computer and provided access to the one or more resources of the computer.

摘要： A method for detecting removal of a filter driver includes performing an operation on an element of a kernel mode of an operating system, the operation initiated by a user mode entity, obtaining the result of performing the operation, and comparing the result of performing the operation against an expected result of the operation. If the result of performing the operation matches the expected result of the operation, it is determined that a file system filter driver in the kernel mode of the operating system is working correctly. If the result of performing the operation does not match the expected result of the operation, it is determined that a file system filter driver in the kernel mode of the operating system has been compromised by malware.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for obfuscated malware. In one aspect, a method includes executing from a binary executable a call instruction and a plurality of instruction subsequent to a target of the call instruction, determining if the value identified by the stack pointer of the call stack is equal to a default value stored in the call stack prior to emulation, determining if there is a non-obfuscation signal resulting from the execution of the call instructions and the plurality of instructions, and if the value identified by the stack pointer is the default value and there is no obfuscation signal, identifying the call instruction as a possibly obfuscated call instruction; Additionally, the method includes determining that if the number of call instructions identified as possibly obfuscated call instructions exceeds a threshold number, identifying the binary executable as an obfuscated executable.

摘要： Assessing ransomware impact includes receiving an indication of a first plurality of files stored on a user device and a classification for each of the first plurality of files, determining a second plurality of files stored in a remote storage, wherein the second plurality of files corresponds to an indication of files stored on the user device at a first prior time, wherein each of the second plurality of files are associated with a second classification, determining a third plurality of files comprising files included in the first plurality of files and not included in the second plurality of files, and calculating a risk assessment based on classifications for each of the third plurality of files.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting obfuscated malware. In one aspect, a method includes identifying call instructions in a binary executable; executing the call instruction; executing instructions subsequent to a target of the call instruction; determining that an address identified by a stack pointer is different from the return address; in response to the determination that the address is different, determining if there is a non-obfuscation signal; if there is a non-obfuscation signal, identifying the call instruction as a non-obfuscated call instruction; if there is not a non-obfuscation signal, identifying the call instruction as a possibly obfuscated call instruction; determining whether the call instructions identified as possibly obfuscated call instructions exceeds a threshold; in response to the determination that the call instructions identified as possibly obfuscated call instructions exceeds the threshold, identifying the executable as an obfuscated executable.

摘要： A technique allows a parentally attested security token to serve as authentication for a minor using identifying attributes of the minor child. The security token may include personally identifiable information about the child, a description of authorized activity as well as specifications of intended use of the security token. The security token may include provisions for authentication to be revoked by a parent or guardian and/or expire after a predetermined time. The security token may be stored inside a trusted execution environment of a portable computing device that may be carried by the minor and presented at physical locations where authentication is required.
