How to trace Spam Mail
How to trace Spam Mail:-
Spammers often forge the headers of their email in an attempt to avoid losing their accounts and to evade email filters. These notes may help you track the source of spam. The most important thing is to have a mail reader that can show you the full headers of an email in question. The important lines are as follows:
From:
Who the message is from. This is the easiest to forge, and thus the least reliable.
From
As distinct from the "From:" line. This line is not actually part of the email header, but mail transfer software often inserts it when the mail is received. Many Unix mailers use this line to separate messages in a mail folder. This line will always be the first line in the headers.
This line can also be forged, but not always.
Reply-To:
The address to which replies should be sent. Often absent from the message, and very easily forgeable. However, it often provides a clue. For example, forged spam often has a legitimate Reply-To: field so that the spammer can receive mail orders.
Return-Path:
The email address for return mail. Same as Reply-To:
Sender:
The account that sent the message. Mail software is supposed to insert this line if the user modifies the From: line. Most Mail software is broken in this respect, so this line is rarely present. Some mailers provide an X-Sender: line.
Message-ID:
A unique string assigned by the mail system when the message is first created. This is also forgeable in most cases, but requires a little more specialized knowledge than forging the From: line. Also, the Message-ID: often identifies the system from which the sender is logged in, rather than the actual system where the message originated.
The format of a Message-ID: field is @
Each kind of mail software has its own style of unique string. Sloppy forgeries often get it wrong, thus a forgery can be confirmed by comparing the message id with some legitimate messages from that same site.
Received:
These are the most reliable lines in the header. They form a list of all sites through which the message traveled in order to reach you. They are completely unforgeable after the point where it was injected. Up to that point, they may be forgeries.
Received: lines are read from bottom to top. That is, the first Received: line is your own system or mail server. The last (non-forged) Received: line is where the mail originated.
Each mail system has their own style of Received: line. A Received: line typically identifies the machine that received the mail and the machine that the mail was received from. I.e.:
Received: from foo.com by bar.com id AA15057; Fri, 25 Jul 97 09:39:02
The "foo.com" part is the name that the sending machine used to identify itself. This may be forged in the case of spam. The id is for logging purposes and may help system administrators track the spam if you can get them to cooperate with you.
Many mailers will add extra information. For example:
Received: from foo.com ([129.2.3.4]) by bar.com id AA15057; Fri, 25 Jul 97 09:39:02
In this case, bar.com has inserted the IP address of the sending system. If the machine name does not match the IP address, then you have likely identified the point where the mail was forged. In other words, the machine whose address is 129.2.3.4 lied when it identified itself as foo.com. Any Received: lines that follow are likely to be forgeries.
If the IP address does not make sense (for instance, no component may be greater than 255), then this entire Received: line is a fake. Contact a system admin for more advice in determining if an IP address is bogus. If the entire Received: line is fake, then the injection point is somewhere above in the headers.
Sometimes you will see
Received: from foo.com (x.y.alterdial.uu.net [129.2.3.4]) by bar.com id AA15057; ...
In this case, the mailer has inserted both the IP address and the real name of the sending system. This will help you identify forgeries and eliminate the need to look up the IP address by hand.
Comment:
Some mailers may add additional information to the headers, such as "Authenticated sender is doe@foo.com". Forged Comment: lines can be easily added to outgoing mail, so this line is likely to be fake, but not always.
Other mailers may insert their own authentication information in the headers.
Here is an example of a forgery:
From webpromo@denmark.it.earthlink.net Tue Jul 8 13:05:02 1997
Return-Path:
From: webpromo@denmark.it.earthlink.net

Obviously, the To: line is a forgery; the actual recipients list was hidden, probably with a blind carbon-copy (Bcc: header)
The "From", "Return-Path:" and "From:" all identify the same email address, but that may be a forgery. You can try mailing to the given address and see if your complaint bounces.
The "To:", "Reply-To:" and "Authenticated sender" lines all identify a different account. Again, these may all be forgeries.
The Message-ID: line is an obvious fake.
The first Recieved: line shows the mail arriving at my service provider from Earthlink. I trust my service provider, so this line is almost certainly valid.
The second Received: line shows this inconsistency:
... from mail.earthlink.net (1Cust98.Max16.Detroit.MI.MS.UU.NET [153.34.218.226])
In other words, the machine that delivered the mail to denmark.it.earthlink.net identified itself as mail.earthlink.net but was actually named 1Cust98.Max16.Detroit.MI.MS.UU.NET. This is very likely a lie. However, Earthlink rents POPs from Uunet, so this might be an Earthlink customer dialing in from Uunet.
The third Received: line is completely bogus. If the mail came from a dial-in customer at Uunet, there wouldn't be any more Recieved: lines. If the mail was being relayed from Uunet, this Received: line would indicate Uunet, not Earthlink. Further, this Received: line contains email addresses, not machine names.
Clearly, this email was forged to make it look like it came from Earthlink but was actually injected from Uunet. Whether this was by an Earthlink customer or some other Uunet customer is impossible to tell without cooperation from Earthlink sysadmins.
Here is another forgery:
Received: from cola.bekkoame.or.jp (cola.bekkoame.or.jp [202.231.192.40])

Here, the second Received: line indicates that "cola.bekkoame.or.jp" received the mail from a machine which identified itself as "cola.bekkoame.or.jp", but was in fact "ip21.san-luis-obispo.ca.pub-ip.psi.net". This mail was probably forged from a Psi.net dial-in account.
As a final proof, the IP address mentioned in the third Received: line cannot be matched via whois or traceroute. It certainly doesn't match AOL, indicating that this line is bogus.
Some security Tips:-
Some security Tips:-
How to protect yourself online. There are four major areas that I'm going to cover here:-
1. Updating Windows
2. Firewalls
3. Antivirus Software
4. Email
Updating Windows is the first suggestion that I would have for you. When you installed your brand new Windows operating system they didn't have all the bugs worked out of it and they issue updates for your operating system. These updates will fix many of the security holes that were found in the original operating system. So, how do you go about updating your Windows? Go to http://windowsupdate.microsoft.com/
Next suggestion is a firewall, with the ever increasing number of people with a broadband connection and 24/7 connectivity it becomes even more important that you put a firewall on you computer. Your computer has a series of ports that are either opened or closed to receive and send information onto the net. If someone attacks these ports with D.O.S. (Denial of Service) attack they can shut your connection to the net off, but that's not that bad, but they can also look at these open ports and find openings in your computer. This is serious because they can gather information on you, can look into you hard drive, and do all sorts of malicious activities. Go to the Firewall section of the website to download one of the free software programs there. They will make your computer even more safe then it was with the security updates you just completed.
The third and final suggestion is Antivirus software. Viruses can range in severity from something simple and annoying to viruses that will wipe your hard drive clean. So you need to get an Antivirus software program. AVG is a free virus scanner that works excellently at protecting your computer. Read more about the antivirus software at the Antivirus section of this website. Antivirus software will also help prevent Trojans from getting on you computer. Trojans allows a user to have remote access to your computer, yes, just like the trojan horse it sits on your computer waiting for the person that put it there to use it...so antivirus software will work wonders on your computer. Make sure you keep the virus definitions up to date! Also avoid downloading email attachments, downloading files from an untrustworthy site, and make sure you frequently scan you hard drive.
Email - No reputable place will ask for you to fill in your credit card information in an email, delete it or sending it to your ISP to point out this danger. If you get an email from EBAY or AOL or any other big company and there is this link in the email asking you to update your credit card info, don't do it, it's a scam, don't do it, they just make a webpage that looks like Ebay or AOL. This is a quick way to get your credit information stolen...so basically use some commonsense when you're reading your emails.
