Hacking on xp part 3How to Forge Email with Windows XP TelnetWant a computer you can telnet into and mess around with, and not get into trouble nomatter what you do to it? Ive set up mytechbroker.com (206.61.52.33) with user xyz, password guest for you to play with. Hereshow to forge email to xyz@techbroker.com usingtelnet. Start with the command:C:>telnet techbroker.com 25Connecting To Techbroker.com220 Service readyNow you type in who you want the message to appear to come from:helo santa@techbroker.comTechbroker.com will answer:250 host readyNext type in your mail from address:mail from:santa@techbroker.com250 Requested mail action okay, completedYour next command:rcpt to:xyz@techbroker.com250 Requested mail action okay, completedYour next command:data354 Start main input; end with .Newbie note: just means hit return. In case you cant see that little periodbetween the s, what you do to end composing your email is to hit enter, type aperiod, then hit enter again.Anyhow, try typing:This is a test..250 Requested mail action okay, completedquit221 Service closing transmission channelConnection to host lost.Using techbrokers mail server, even if you enable full headers, themessage we just composed looks like:Status: RX-status: NThis is a test.Thats a pretty pathetic forged email, huh? No from, no date.However, you can make your headers better by using a trick with the data command.After you give it, you can insert as many headers as you choose. The trick is easier toshow than explain:220 Service readyhelo santa@northpole.org250 host readymail from:santa@northpole.com250 Requested mail action okay, completedrcpt to:250 Requested mail action okay, completeddata354 Start main input; end with .from:santa@deer.northpole.orgDate: Mon, 21 Oct 2002 10:09:16 -0500Subject: RudolfThis is a Santa test..250 Requested mail action okay, completedquit221 Service closing transmission channelConnection to host lost.The message then looks like:from:santa@deer.northpole.orgDate: Mon, 21 Oct 2002 10:09:16 -0500Subject: RudolfThis is a Santa test.The trick is to start each line you want in the headers with one wordfollowed by a colon, and the a line followed by return. As soon asyou write a line that doesnt begin this way, the rest of what youtype goes into the body of the email.Notice that the santa@northpole.com from the mail from: command didnt show up inthe header. Some mail servers would show both from addresses.You can forge email on techbroker.com within one strict limitation.Your email has to go to someone at techbroker.com. If you can find any way to sendemail to someone outside techbroker, let us know, because you will have broken oursecurity, muhahaha! Dont worry, you have my permission.Next, you can read the email you forge on techbroker.com via telnet:C:>telnet techbroker.com 110+OK service readyGive this command:user xyz+OK user is knownThen type in this:pass test+OK mail drop has 2 message(s)retr 1+OK message followsThis is a test.If you want to know all possible commands, give this command:help+OK help list followsUSER userPASS passwordSTATLIST [message]RETR messageDELE messageNOOPRSETQUITAPOP user md5TOP message linesUIDL [message]HELPUnless you use a weird online provider like AOL, you can use thesesame tricks to send and receive your own email.
