Abstract

The invention relates to a method and device for detecting and intercepting Mimikatz, computer equipment and a readable storage medium. The method comprises the following steps of: obtaining dll filesin a dynamic link library loaded during process operation in real time; comparing the dll files with dll files in a Mimikatz-dll feature library one by one, wherein the Mimikatz-dll feature library is a feature library formed by dll files loaded during Mimikatz operation; when the dll files comprises all the dll files in the Mimikatz-dll feature library, intercepting processes corresponding to the dll files; and when the interception succeeds, returning the dll files, , obtained in real time in the dynamic link library loaded during the process operation.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and readable storage medium for detecting and intercepting Mimikatz. Background technique [0002] Mimikatz is a lightweight debugging tool written by the French. It has many functions, such as elevating process privileges, injecting process, reading process memory, etc. It is more known to use Mimikatz to obtain Windows plaintext passwords. . Mimikatz can obtain memory from the Windows authentication process, and obtain plaintext passwords and NTLM (NTLAN Manager, standard security protocol) hash values, attackers can use this to roam the intranet. [0003] The Mimikatz attack tool will not only cause the passwords in the Windows system to be disclosed, but also use this attack tool as a vulnerability exploit tool combined with other malware, which will cause great harm to network security. For example, the new ransomware "Bad R...
