Why do small sites get hacked?

small-sites3
If you think your site won't be hacked because it's too small to matter, think again. I'll show why that is a false and dangerous assumption. Many site owners and webmasters think that hackers only care about popular, highly-ranked websites. They are wrong. High traffic volume helps boost earnings on partner programs by redirecting visitors to other sites, gets more views of unauthorized advertisements and attracts more clicks on rogue links. But that is not the only way hackers make money. Unprotected sites with low traffic volume are equally attractive to hackers. It is the way they are used that differs from how hackers monetize more popular websites. Any normal site, with an audience of ...

How Spammers Spam

spammers
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. The diagram below shows an overview of the methods. ​ 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. Spamming by hacking A hacked site or server is the most common reason behind an outbreak of spamming a...

Why Does Site or Server Load Increase?

Why server load increases
There's only one good reason why the load on your hosting server starts increasing–the rest are bad. I'll look at how and why they all happen. I was often contacted by site owners who had a problem with high server load. This common condition is first noticed when an owner gets a warning message from their hosting company. Such messages can be precursors to the blocking of the site, and it can happen to almost any site owner or webmaster. This article covers the different reasons why the load on a site or server might be increasing, and what can be done about it. Webmasters usually find out about excess load from their hosters. Hosting companies regulate and control resource usage for each h...

Patterns of thought: the psychology of weak passwords

psychology1
In this article, I look at why webmasters, site administrators and their users choose and use weak passwords. Later, I recommend ways to create passwords that are reliable and resistant to brute-force attacks. Warnings that the internet is increasingly an unsafe environment appear with alarming regularity in studies commissioned by companies specializing in information security. The growing number of web attacks and the increasing activity of the hacker community require a new discipline and focus on security. But while cybersecurity experts are talking about high technology and advanced protection, it seems a rudimentary rule has been forgotten: the use of strong passwords. Unreliable passw...

Avoid Multi-Site Hacking – Part 2

Security solution for web hosting
In Part 1 , we looked at security isolation as a technical solution for preventing infections on one site spreading to neighboring sites in multi-site hosting systems. In Part 2, we'll consider other non-technical ways to beef up multi-site protection. Site security = technical protection + organizational measures If you don't use security isolation on sites in the same hosting account, you should at least give each site its own account. However, this is often impossible, as the combined sum of each site's content resource needs (disk, memory) is too great. This is where the next elements of complex security come in. I call them organizational measures . Here are some examples. ​ Secure work...

Avoid Multi-Site Hacking – Part 1

avoid-part1
Running shared or VPS servers has risks. When one site is hacked, neighbors succumb shortly after. In this two-part article, I'll explain the risks in detail and what you can do to mitigate them. Shared hosting and VPS servers allow you to host several sites within one user account. If you're a webmaster, a web studio, an Internet agency, or a business owner, you do this not only for convenience but also to save money, as it is cheaper than buying separate accounts for each site. But there's a problem. Multi-site accounts are vulnerable to hacking and the subsequent infection of the entire hosting account. Often, there are dozens of "patients" (tenants) on the same site who urgently need tre...
