  • Patent number: 9613207
    Abstract: Provided is a technology which creates an autorun file that is used in autorun for preventing the autorun of a USB-based portable storage, thereby allowing an arbitrary user or worm virus not to manipulate the autorun file. A method for preventing autorun of portable storage accesses at least one of a master file table entry of a root directory and a master file table entry of an autorun file, and sets non-autorun in the at least one accessed master file table entry.

  • Patent number: 9164845
    Abstract: Provided is a technology which searches an unallocated area to quickly extract information on a deleted partition when checking a disk and an evidence image in digital forensic, and adds a recovered partition to a forensic tool as a new partition. For this, the technology has direct access to the sector of a disk or an evidence image which is obtained, limits information search on an unallocated area only to an area satisfying the minimum size in which a partition may be created, changes an LBA-based sector access scheme into a CHS-based sector access scheme, and reads only the sector of a location having the possibility that a boot record exists to search information of a deleted partition, recovering a partition at high speed.

  • Patent number: 9032516
    Abstract: Provided are a system and method for detecting a malicious script. The system includes a script decomposition module for decomposing a web page into scripts, a static analysis module for statically analyzing the decomposed scripts in the form of a document file, a dynamic analysis module for dynamically executing and analyzing the decomposed scripts, and a comparison module for comparing an analysis result of the static analysis module and an analysis result of the dynamic analysis module to determine whether the decomposed scripts are malicious scripts. The system and method can recognize a hidden dangerous hypertext markup language (HTML) tag irrespective of an obfuscation technique for hiding a malicious script in a web page and thus can cope with an unknown obfuscation technique.

  • Patent number: 8273211
    Abstract: Disclosed herein is a flat panel display manufacturing apparatus in a predetermined process is performed using plasma generated therein. In such a flat panel display manufacturing apparatus, a process gas is supplied into a chamber in an evenly diffused state to generate even plasma inside a symmetrical interior space of the chamber. Consequently, the flat panel display manufacturing apparatus can appropriately control flow rate of the plasma, thereby being capable of performing even processing on a large-scale substrate. In the flat panel display manufacturing apparatus, a substrate pedestal thereof is provided with a combination of vertical and horizontal shielding members, thereby being entirely protected from attack of the plasma, resulting in an increased life-span.
