How to Determine the Origin of Spam
Introduction
Spam will persist as long as it remains profitable. If no one buys from spammers or falls for their scams, spam would diminish. Ignoring and deleting spam emails is an easy way to fight back. However, you can go further by reporting spammers to their Internet Service Provider (ISP). The ISP may block their connection and potentially impose fines, depending on their acceptable usage policy. Spammers are wary of such complaints and often disguise their messages, making it challenging to trace them.Examining a Spam Message
Every email has two main components: the body and the header. The body contains the message text and attachments, while the header acts like an envelope. The header includes:- From: Sender's name and email address
- To: Recipient's name and email address
- Date: When the message was sent
- Subject: The message subject
Spammers frequently forge the information in the "From" field, making it unreliable for tracing their origin.
Using Email Headers to Trace Spam
To uncover the origin of a spam email, analyze the header fields, particularly the "Received" lines. These lines indicate the path the email took through various mail servers. Each server adds a "Received" line, documenting:- The IP address of the preceding machine
- The server's own details
The headers help reconstruct the email's path from sender to recipient. Start with the topmost "Received" line and work downward to find its origin.
Identifying Forged Information
Spammers may insert fake "Received" lines, resembling legitimate ones. Analyzing the entire chain of "Received" lines can help spot forgeries. Compare server names and addresses in consecutive lines?"discrepancies indicate a forged entry.Real-World Example
Consider a sample spam email header:- Received: from unknown (HELO 60.17.139.96) (221.200.13.158) by mail1.myserver.xx with SMTP; 7 Nov 2006
- Received: from 164.145.240.209 by 60.17.139.96; 7 Nov 2006
Here’s how to analyze it:
1. Check Consistency: The first "Received" line indicates that the message was allegedly received from 60.17.139.96 by mail1.myserver.xx. Verify this with subsequent lines.
2. Trace the Origin: mail1.myserver.xx confirms this transaction. However, the address in brackets [221.200.13.15] indicates a different source, revealing a possible forgery. The message likely originates from 221.200.13.15.
3. Consider Hijacking: Remember, the spammer might not directly use the machine at 221.200.13.15; it could be hijacked by malware spreading spam unknowingly.
Conclusion
By analyzing email headers, you can identify the spammer's ISP and report them, encouraging the ISP to take action. With diligence and the right tools, you can help mitigate spam and its impact.You can find the original non-AI version of this article here: How To Determine The Origin Of Spam .
