According to an embodiment of the disclosure, an electronic device is provided. The electronic device includes a communication module and at least one processor connected to the communication module. The at least one processor is configured to configure a call setup with an external electronic device through the communication module. The at least one processor is configured to control the communication module to transmit at least one request message based on a first protocol through the communication module, and receive at least one response message corresponding to the request message. The at least one processor is configured to control the communication module to transmit a howling generation sound source through the communication module, and receive a howling response corresponding to the howling generation sound source. The at least one processor is configured to determine whether a call between the electronic device and the external electronic device is a normal call.

Electronic device for determining call type with external electronic device and method thereof

A server may include a communication circuit and at least one processor. The at least one processor may be connected to a first electronic device and a second electronic device, using the communication circuit, and may be configured to: obtain first call log information including at least one outgoing call made using a call function of the first electronic device by the second electronic device, determine whether the second electronic device satisfies a first condition for determining that the second electronic device is a spam caller, based on the first call log information, search for one or more external electronic devices located around the second electronic device, based on the first condition being satisfied, obtain second call log information about the one or more external electronic devices, and determine at least one of the one or more external electronic devices or the second electronic device as a spam caller, based on the second call log information.

Electronic device for detecting spam call and method of operating the same

An operation method in an electronic device for mitigating location tracking, and a non-transitory storage medium are provided. The electronic device includes a communication module, a memory and at least one processor electrically connected to the communication module and the memory, wherein the at least one processor is configured to identify a type of at least one executed application, randomly select at least one information element to be included in a frame for wireless communication for the at least one executed application, based on the identified type, generate at least one frame comprising the at least one selected information element, and control the communication module to transmit the at least one generated frame through the wireless communication.

Electronic device, method, and non-transitory storage medium for mitigating location tracking

A base station of a communication system may include an antenna; a memory; and a processor. The processor analyzes a signal received through the antenna to determine if the received signal is a signal transmitted from a fake base station. Based on a determination that the source of the received signal is the fake base station, the processor generates a random access preamble signal for accessing the fake base station. The processor transmits the generated random access preamble signal through the antenna. Thus, the base station may effectively defend against an attack from a fake base station by detecting the fake base station based on collected information of a neighboring base station and causing radio resources of the detected fake base station to be exhausted. Various other embodiments are possible.

Method, management server, and base station for defending attack from fake base station in communication network

A method of identifying a malicious access point (AP) by a terminal apparatus includes obtaining first performance information related to hardware of a first AP based on a first beacon signal received from the first AP, comparing the first performance information with previously stored second performance information of a second AP, and determining whether the first AP is a malicious AP, based on a result of the comparing.

Terminal device and method for identifying malicious AP by using same

Disclosed are an electronic device capable of verifying security of a Wi-Fi network and a controlling method thereof. To be specific, the electronic device, in response to the received user command, obtains, through a first channel, first information related to an address of the website, and obtains, from a server providing the website through a second channel, second information related to the address of the website, based on the first information and the second information being identical, maintains communication with the server through the first channel, and based on the first information and the second information being different, terminates the communication with the server through the first channel or communicate with the server through the first channel according to the second information.

Electronic device and controlling method of electronic device

A server is provided. The server includes a communication interface configured to communicate with an electronic apparatus connected to an Internet of things (IoT) device, a storage configured to store a scenario about an attack received by the IoT device from an external apparatus by stages and information relating to a malicious code corresponding to the scenario, and a processor configured to, based on the IoT device being attacked by the external apparatus over at least one step through the electronic apparatus, receive, from the electronic apparatus, an alert for an attack received by stages, and to identify information relating to a malicious code corresponding to at least one alert received from the electronic apparatus based on the pre-stored scenario.
