A method for identifying a wallet address associated with a virtual asset service provider is provided. The method comprises receiving a target wallet address, obtaining a transaction of a virtual asset associated with the target wallet address, obtaining a list of a plurality of known wallet addresses of virtual asset service providers (VASPs) and identifying a type of the target wallet address, by performing at least one of a cold wallet determination routine and a hot wallet determination routine for the target wallet address, based on the transaction and the list of known wallet addresses of the VASPs.

Method and apparatus for identifying wallets associated with virtual asset service providers

A method for identifying a type of a variable within a binary performed on a computing device is provided. The method comprises, identifying a variable from disassembly code of a binary, and determining a type of the variable based on an instruction of the disassembly code, associated with the variable.

Method and device for identifying type of variable in binary

There is provided a method of patching a binary having vulnerability which is performed by a computing device. The method comprises loading a first binary to be patched, into a memory, generating a second binary by patching to call a stack frame initialization function from a vulnerable function of the first binary, executing the stack frame initialization function by calling the vulnerable function when the second binary is executed and initializing a stack frame area of the vulnerable function so as to automatically initialize a variable declared in the vulnerable function.

Method and apparatus for patching binary having vulnerability

Provided is a UV curable coating composition, and more particularly, to a UV curable coating composition including: at least one polyfunctional epoxy oligomer; at least one epoxy compound; at least one non-hydrolyzed epoxy silane; at least one polyfunctional acrylic compound; at least two photoinitiators; and at least one surfactant. The UV curable coating composition according to the present invention can be coated on various substrates and provide excellent adhesion and scratch resistance to the coating layer regardless of a substrate type unlike conventional coating compositions.

UV curable coating composition

Provided is an Internet protocol (IP) generation method. The method is performed by an IP generation apparatus comprising one or more processors and memory and includes: forming a plurality of initialized partial numbers by dividing a decimal number indicating a count of IP addresses that can be generated; changing the partial numbers according to a predetermined rule; generating an IP decimal number by linking the changed partial numbers; generating a random IP address from the IP decimal number; and generating a plurality of different random IP addresses with improved time efficiency, by sequentially repeating the changing of the partial numbers, the generating of the IP decimal number and the generating of the random IP address.

Random IP generation method and apparatus

Provided are a method and an apparatus for identifying computer system information which process banner information of an open port of a computer system, create a CPE tree by analyzing a CPE dictionary, and search keywords of respective levels of the CPE tree in a banner and generate one or more CPEs based on the CPE tree observing a format of the CPE dictionary to select CPEs which most match information of an operating system or an application program of a specific computer system among various CPE candidates and rapidly and easily identify CPE type vulnerability information which can interlock with CVE vulnerability information.

Method and apparatus for identifying vulnerability information using keyword analysis for banner of open port

A device information gathering method is provided. The device information gathering method includes: allowing a device information gathering apparatus to transmit a packet to a randomly generated Internet Protocol (IP) address and to receive a syn-ack packet as a response; allowing the device information gathering apparatus to parse the syn-ack packet and thus to extract Transmission Control Protocol (TCP)/IP fields; and allowing the device information gathering apparatus to compare the TCP/IP fields and an OS fingerprint rule, which is in JavaScript Object Notation (JSON) format, and thus to generate an OS fingerprint of the randomly generated IP address, wherein the OS fingerprint rule stores Operating Systems (OSs) and TCP/IP field values corresponding to versions of the OSs as attribute-value pairs.

Rule-based fingerprint generation methods and apparatus

Provided is an Internet protocol (IP) generation method. The method is performed by an IP generation apparatus and includes: forming a plurality of initialized partial numbers by dividing a decimal number indicating a count of IP addresses that can be generated; changing the partial numbers according to a predetermined rule; generating an IP decimal number by connecting the changed partial numbers; generating a random IP address from the IP decimal number; and generating a plurality of different random IP addresses by sequentially repeating the changing of the partial numbers, the generating of the IP decimal number and the generating of the random IP address.
