  • Patent number: 10963558
    Abstract: A malware detection method and a malware detection apparatus, where the method includes running to-be-detected software in a sandbox, and recording at least one operation, and in a process of recording the at least one operation, when it is detected that any interface that has a delay attribute in the sandbox is called, determining whether delay duration corresponding to a first delay length parameter of the called interface is greater than a preset duration. When the delay duration corresponding to the first delay length parameter is greater than the preset duration, delay duration of delay execution is reduced to enable the malicious behavior to be executed in the process of recording the at least one operation executed within the preset duration after the to-be-detected software starts to run.

  • Patent number: 10565371
    Abstract: A malware detection method and a malware detection apparatus are provided. The method includes running to-be-detected software in a sandbox, and recording at least one operation; and in a process of recording the at least one operation, when it is detected that any interface that has a delay attribute in the sandbox is called, determining whether delay duration corresponding to a first delay length parameter of the called interface is greater than preset duration. If the delay duration corresponding to the first delay length parameter is greater than the preset duration, delay duration of delay execution is reduced to enable the malicious behavior to be executed in the process of recording the at least one operation executed within the preset duration after the to-be-detected software starts to run, and accordingly, the malicious behavior may be exposed in advance.

  • Patent number: 9093781
    Abstract: The present invention discloses a connector assembly includes a connector and a plug. The connector is disposed on the circuit board and includes an insulating socket with a slot. The slot includes an inner first end and an outer second end, and an inner diameter of the second end of the slot is greater than an inner diameter of the first end of the slot. The plug is connected to an end of a power cable for plugging into the connector. The plug includes an insulating portion and a plug portion exposed outside the insulating portion. The plug portion includes a first end which is close to the insulating portion and a second end which is far way from the insulating portion, and an outer diameter of the first end of the plug portion is greater than an outer diameter of the second end of the plug portion.
