How Spammers Spam

How-Spammers-Spam

Twenty years on and spam is still a problem. I'll look at why that is and what we can do to reduce or prevent it.

Contrary to popular belief, hacking a site and uploading malicious scripts onto it is not the only way spamming gets a foothold. There are other ways. For example, it could be because of a compromised account, the use of script vulnerabilities, or an incorrectly configured mail server.

In this article, I'll look at the different ways unsolicited email (spam) can emanate from a web server, and some of the ways you can stop it.

This article covers the different reasons why the load on a site or server might be increasing, and what can be done about it.

Avoid Multi-Site Hacking – Part 1
