摘要： Embodiments herein include an alternative approach to vulnerability detection, denoted as an automated network vulnerability identification and localization application (ANVIL). More specifically, a network includes multiple hardware and software-based entities that communicate with each other over standardized or proprietary protocol interfaces with the objective of providing data, computing capabilities, or voice connectivity to an end user such as a mobile device. For example, a device-based or core network-based instance of ANVIL emulates different protocol layers in order to periodically scan and probe the message responses of different protocol layers and the accessibility of different network interfaces to unauthorized users. Fuzzing message responses are used to generate new fuzzing messages based on machine learning techniques in order to localize potential vulnerabilities. Multiple protocol layers and communication protocols may be emulated and multiple network entities may be probed by a single instance of ANVIL. The responses of the network to the fuzzing messages and port scans are collated by ANVIL and reported to an administrator via a dashboard that highlights potential vulnerabilities in the network and suggested remedies.

摘要： Accurate and reliable time is acquired by a user equipment (UE) from a base station in a wireless network. The base station may obtain the time, e.g., UTC time or a GNSS time, and ciphers at least a portion of the time before broadcasting the time. The UE determines a propagation delay between the UE and the base station based on a timing advance, known locations of the UE and the base station, or a measured round trip propagation time (RTT) between the UE and the base station. A corrected time can be determined based on the time received from the base station and the propagation delay. A digital signature included with the time broadcast by the base station increases reliability. Spoofing of the broadcast time by an attacking device may be detected by the UE based on the propagation delay being outside an expected range.

摘要： A detection device includes: a monitoring unit configured to monitor, as target messages, an authorized message being periodically transmitted and the unauthorized message in the in-vehicle network; and a generation unit configured to generate a reference time to be used in a detection process of detecting the unauthorized message; a detection unit configured to perform detection process, based on time difference between a time corresponding to a transmission time of target message based on a monitoring result of the monitoring unit, and the reference time generated by the generation unit. When target message has been determined to be abnormal in the detection process, the generation unit, based on a value obtained by adding a latest statistical value to the reference time, generates a new reference time to be used in the detection process for a target message to be transmitted after the target message having been determined to be abnormal.

摘要： Disclosed are systems, methods, and non-transitory computer-readable media for verifying an incoming communication. A recipient client device receives an incoming communication including an identifier identifying a second client device as having initiated the incoming communication. A verification service installed on the recipient client device queries a call placement service directory based on the first identifier. The call placement service directory maintains a listing of identifiers for client devices and corresponding communication providers that manage the identifiers. The call placement service directory returns information identifying the communication provider that manages the identifier. In turn, the verification service transmitting a request to the communication provider to confirm whether the second client device initiated the incoming communication. The verification service processes the incoming communication based on the response from the communication provider indicating whether the second client device initiated the incoming communication.
