  • Patent number: 11838414
    Abstract: An apparatus and method for encryption key recovery based on memory analysis. The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program may collect memory information pertaining to an encrypted part of a file, in which ransomware is detected, based on dynamic binary instrumentation, analyze memory read operation data corresponding to an encryption key that is used for encryption of the file in the memory information, recover the encryption key based on the result of analysis of the memory read operation data, and output the result of recovery of the encryption key.

  • Publication number: 20050234854
    Abstract: A system and a method for calculating a growth/evolution mode of an agent for a proactive user interface in a terminal are disclosed. The system includes a server for storing data corresponding to elements of an agent according to versions and growth steps and providing the terminal with element data of a corresponding agent when the terminal makes a request for the data of the agent, and the terminal for making a request for the data of the agent, which are necessary for calculating the growth/evolution mode of the agent, to the server, and receiving the data of the agent from the server, thereby calculating the growth/evolution mode of the agent.
