Abstract

The present invention discloses a method and apparatus for cracking a password of an Oracle database account. The method comprises: modifying system tablespace via an Oracle block browser and editing tools; setting a block address of a data block storing a super administrator password in the system tablespace; calling a function to obtain the super administrator password stored in the data block; setting a value of an obtained field storing the super administrator password to a new super administrator password; and after determining the new super administrator password is set successfully, restarting an Oracle database to obtain data. The method described above causes a data file of the data block to be directly read by using a BBED tool, so that a user can find the data block storing the super administrator password and reset the data block, and then the user can log in to the Oracle database to obtain the data. Accordingly, the user can log in to the Oracle database to obtain the data, regardless of which authentication mode is employed in the Oracle database.

Description

technical field [0001] The invention relates to the field of computer database systems, in particular to a method and a device for cracking an Oracle database account password. Background technique [0002] Oracle database is a relational database management system with distributed database as the core provided by Oracle Corporation (Oracle), and it is one of the most popular client / server (Client / Server) or B / S architecture databases. [0003] In the prior art, password authentication is usually required to obtain data from the Oracle database. There are two ways of password authentication for the Oracle database, namely system-level authentication and database-level authentication. If system-level authentication is used, the user You only need to log in to the host without entering a password to log in to the database. If database authentication is used, the user must enter a password to log in to the database. [0004] However, with the prior art, when system-level authe...
