Why is it important to find default login and password?

For any software or application, default login and password are usually set during installation, and keeping them unchanged poses a significant security threat. Default credentials are widely known and can be easily exploited by hackers to gain unauthorized access to the system, which can cause severe damage.

Finding and changing the default login and password is crucial for securing your system and data. Changing default login credentials ensures that only authorized users have access to the system, and potential cyber-attacks are prevented. Default credentials weaken the security posture of the system and create an easy entry point for malicious hackers. With the increase in cyber-attacks, finding and changing the default login and password has become an essential step in securing the system.

By uncovering the default login and password, system administrators can ensure they are not using vulnerable usernames and passwords, which can be used to gain access to crucial system data. It is crucial to take the necessary steps to secure your system and data, and finding and changing the default login and password is an essential step in that direction.

Code example 1: Using SQL*Plus

If you're looking to unlock the secrets to Oracle 11g, one way to do so is by using SQLPlus. SQLPlus is a command-line interface that enables you to connect to a Oracle database, execute SQL statements, and interact with the database. Here's how to use SQL*Plus to find your default login and password:

  1. Open SQL*Plus, which can be done by typing "sqlplus" on the command line.

  2. Enter your default username and password, which are typically "system" and "manager", respectively. If you're not sure what your default username and password are, you can try using these credentials.

  3. Once you're logged into SQL*Plus, you can execute SQL statements to find your default login and password. The following SQL statement can be used to retrieve this information:

SELECT username, password FROM dba_users;
  1. When you run this SQL statement, the output will include all usernames and passwords stored in the database. Look for the row that corresponds to your default login, which should be "SYSTEM" if you haven't changed it.

  2. The password for your default login will be displayed in encrypted form. To decrypt it, you can use the following command:


This will display the decrypted password for your default login. Keep in mind that it's generally not recommended to store passwords in plaintext, so your password may be encrypted or hashed in a different way depending on your security settings.

Using SQL*Plus is an effective way to unlock the secrets to Oracle 11g and find your default login and password. By following these steps, you'll be able to access important information stored in the database and take control of your Oracle environment.

Code example 2: Using Enterprise Manager Database Control

Another way to find your default login and password in Oracle 11g is to use the Enterprise Manager Database Control. This is a tool that allows you to manage your Oracle database through a web interface.

To find your default login and password using this tool, follow these steps:

  1. Open your web browser and navigate to http://hostname:portnumber/em. Replace hostname with the hostname of your database server and portnumber with the port number that Enterprise Manager is running on.

  2. Log in to Enterprise Manager using your Oracle administrator account.

  3. Once you're logged in, click on the Database tab and then click on your database instance.

  4. In the Database Home section, click on the Administration tab and then click on Users.

  5. You should see a list of users in your database. Look for the user with the name SYS or SYSTEM. These users are the default administrator accounts in Oracle 11g.

  6. Click on the user and then click on Edit.

  7. In the Edit User screen, you should see the default password for the user.

  8. If you need to change the password, you can do so here as well.

Using the Enterprise Manager Database Control can be a quick and easy way to find your default login and password in Oracle 11g. Just be sure to use this tool with caution and only for legitimate purposes.

Code example 3: Using Oracle Universal Installer

If you have installed Oracle 11g using Oracle Universal Installer, you can find the default login and password in a specific file. Here is an example of how to locate this file and extract the login and password:

  1. Open the Oracle Universal Installer.

  2. Click on the "Installed Products" button.

  3. Select the Oracle home that you want to retrieve the login and password for.

  4. Click on the "Details" button.

  5. Click on the "Inventory" tab.

  6. Look for the file called "orapw<ORACLE_SID>" in the "Central Inventory Location" field. This file contains the encrypted login and password for the Oracle Database administrator.

  7. Copy this file to a safe location on your computer.

  8. Use the "orapwd" utility to extract the login and password from the "orapw<ORACLE_SID>" file.

  9. Open a command prompt and navigate to the directory containing the "orapw<ORACLE_SID>" file.

  10. Type the following command: "orapwd file=orapw<ORACLE_SID> password=<your_password> ignorecase=n"

  11. Replace "<your_password>" with the password you want to use to log in to the database as the SYS user.

  12. The utility will prompt you to enter the new password for SYS.

  13. Once you have changed the password, you can log in to the database using the username "SYS" and the new password you just set.

Using Oracle Universal Installer, you can easily locate and extract the default login and password for your Oracle 11g database. By following the steps above, you can set a new password and gain access to the database as the SYS user.

Code example 4: Accessing Oracle 11g Database via JDBC

To connect to an Oracle 11g database using Java Database Connectivity (JDBC), you will need to first make sure that you have downloaded and installed the latest version of the Oracle JDBC driver. Once you have done this, you can begin writing code to connect to the Oracle 11g database.

Here is an example code snippet that demonstrates how to connect to an Oracle 11g database using JDBC:

import java.sql.*;

public class Test {
   static final String JDBC_DRIVER = "oracle.jdbc.driver.OracleDriver";  
   static final String DB_URL = "jdbc:oracle:thin:@localhost:1521:XE";
   static final String USER = "system";
   static final String PASS = "password";

   public static void main(String[] args) {
      Connection conn = null;
      Statement stmt = null;
      try {

         System.out.println("Connecting to database...");
         conn = DriverManager.getConnection(DB_URL,USER,PASS);

         System.out.println("Creating statement...");
         stmt = conn.createStatement();
         String sql;
         sql = "SELECT id, name, age FROM Employees";
         ResultSet rs = stmt.executeQuery(sql);

            int id  = rs.getInt("id");
            int age = rs.getInt("age");
            String name = rs.getString("name");

            System.out.print("ID: " + id);
            System.out.print(", Age: " + age);
            System.out.println(", Name: " + name);
      } catch(SQLException se) {
      } catch(Exception e) {
      } finally {
         try {
         } catch(SQLException se2) {
         try {
         } catch(SQLException se){

In the above code, we first define the JDBC driver and URL for the Oracle 11g database. We also specify our username and password for the database.

We then use the DriverManager.getConnection() method to create a connection to the database, and the conn.createStatement() method to create a Statement object for executing SQL queries.

Next, we write a SQL query to select all records from the Employees table, and use the stmt.executeQuery() method to execute the query and get a ResultSet object.

We then loop through the ResultSet object and print out the values of the id, age, and name columns for each record.

Finally, we close the ResultSet, Statement, and Connection objects, and print out a message saying goodbye.

Overall, this code provides a basic framework for accessing and querying an Oracle 11g database through JDBC. By modifying the SQL query or adding additional code, you can perform a wide range of database operations using this method.
