  • Patent number: 8166543
    Abstract: Provided is an apparatus and method for detecting a malicious file that attempts to initiate communication in a mobile terminal without a user's approval. The method of detecting a malicious file in a mobile terminal includes: determining whether a file to be examined is an executable file; when the file is an executable file, examining whether the file is a malicious file that can cause unapproved communication based on at least one predetermined examination condition; and outputting the result of examining whether the file is the malicious file. Accordingly, an attack caused by a new type of malicious code can be coped with.

  • Publication number: 20120041102
    Abstract: The present invention relates to a novel epoxy resin having improved heat-resistance, thermal expansion properties and processability, and to a thermosetting resin composition comprising the same. To this end, the present invention provides an epoxy resin of Chemical Formula 1 as disclosed in the Description, an epoxy resin composition comprising the same, and a packaging, substrate and transistor formed thereof. When a composition that contains an epoxy resin with a specific side functional group according to the present invention and/or an epoxy resin with a specific core structure is cured, a filler forms a strong chemical bond with the epoxy resin, thereby maximizing filling effects of the filler for the epoxy resin. Moreover, with the specific core structure, heat resistance and heat expansion properties of a cured product are substantially improved (CTE is reduced), and enhanced glass transition properties, strength and processability are demonstrated.

  • Publication number: 20090138969
    Abstract: A device and method for blocking autorun of a malicious code through an autorun file stored in a removable storage device are provided. A device manager monitors a connection of a removable storage device, acquires a global unique identifier of the removable storage device, and deletes an autorun file for running the malicious code from the removable storage. A registry manager determines whether a registry key for storing content of the autorun file is generated using the global unique identifier of the removable storage device and deletes the registry key. The present invention can block autorun of a malicious code stored in the removable storage device by retrieving and deleting a registry key for performing the autorun technique when a removable storage device is connected to a system.
