The problem with hackers attacking websites is on a constant rise. Month-to-month we list tens of vulnerabilities found in popular plugins that developers use on their sites.
Most of these are being targeted by hackers. We monitor the sites we protect daily and see the number of attacks increasing every week.
The reason why hackers are hacking websites is still a mystery for a lot of people. So, in this article, you are going to learn why hackers hack websites.
If you are a web developer, agency, or freelancer who is responsible for websites, you probably have seen this issue. If you are a website owner or newbie on the field, a hacked site can come as a big surprise.
This article will help you to understand why are hackers attacking websites, what are they doing with a hacked website and what should you do when your site gets hacked.
You probably think that you are not holding any state secrets on your site, maybe not even collecting credit card details, but you still got hacked – why?
Or maybe you only have a small one-pager with a little text and a contact form and somehow you still end up on a hackers’ radar.
How is it possible, you ask?
Well, it isn’t you or your site specifically in most cases. Nor is it your business behind the site. Hackers are targeting the software that you use.
When they are successful they can generate money. And the latest data has shown that about 50 000 sites get hacked every day. It may mean a lot of money for hackers, right.
Even a small website can generate a substantial amount of money. Cybercriminals and web hackers can make money with your compromised website by distributing malware, SEO spam, and even set up e-mail spam servers and phishing sites.
Money is obviously the most common motivation behind the attacks.
If you dig deeper you see that there are actions that hackers take to make money. One of these is SEO spam.
What is SEO spam?
SEO spam is a type of spam. It is basically an action of injecting backlinks and spam to legitimate sites. It remains one of the most profiting and popular types of website attacks.
After the website is compromised, a malicious backdoor will be uploaded to the website which gives access to the attacker allowing him to invisibly redirect your visitors to their scam sites at any time they want.
Apart from generating money for the hacker, your website gets a penalty from search engines which will ruin your SEO.
“The scam has been traced back to organized crime syndicates operating in what is estimated to be a 431 billion dollar, and growing, market. Its scale, and the danger counterfeit drugs pose to the public health, prompted repeat action from FDA, Interpol, among others.”— Incapsula
Malware is the worst-case scenario, but evil-minded web hackers can even use your website to infect visitors with ransomware.
What is the difference between malware and ransomware?
Malware is malicious software and it is a code that is made to disrupt, disable, or take control of your system. It is usually hidden or disguised as something else so that scanners won’t find it.
When we perform malware removals we do it manually. The reason why we do it manually is that most scanners fail to find malware and if in the best-case scenario they do – there’s still a backdoor that needs to be patched. The patch is very important thus we have real security experts who perform the fix manually.
Ransomware is a specific type of malware. When a victim’s data is encrypted and can only be decrypted with a key that is known to the attacker. So the attacker will hold your data and ask ransom from you so that you could get your data back.
“It’s possible to have your operating system, browser, plugins, and applications exposed to exploits looking for vulnerabilities just by visiting an unsafe website. SophosLabs sees tens of thousands of new URLs every day containing drive-by downloads.”— Sophoslabs
Between 2014 and 2016 over 100 000 WordPress and Joomla sites were redirecting visitors to Neutrino Exploit Kit, which tried to penetrate the browser on the visitors’ computer and when being successful, infected the operating system with CryptXXX ransomware.
It’s also a billion-dollar market: read more here.
According to the latest volume of the Internet Security Threat Report:
$294 = Average amount of money demanded per person in 2015
$1,077 = Average amount of money demanded per person in 2016
$2,000 = Average amount of money demanded per person in 2017
$6,733 = Average amount of money demanded per person in 2018
$13,000 = Average amount of money demanded per person in 2019
When we talk about the year 2020 the data shows that ransomware demand costs could exceed $1.4 billion in the U.S. this year. The numbers are rising in a serious manner and should be alarming to every website owner. You don’t want to pay $13 000 for your data, right?
Going back to malware, there are many other ways to make money with it. For example, hacked websites can be connected to a large botnet, which then can be used to provide a DDoS service to attack other sites and web services.
First of all – updates. Make sure you are always updated to the latest version if any of the new vulnerabilities come out. You can enable auto-updates for vulnerable plugins if you know you don’t have the time to check the new vulnerabilities every day.
Secondly – install a web application firewall. And not any web application firewall please do your research on the technology. It’s crucial to have a firewall that gets constant updates and virtual patches.
There is also a different type of hackers, who are doing the ill-intentioned actions for fun. These hackers attacking websites are the deface web hackers, vandals, and script kiddies. They are oftentimes kids who test their skills and love to show it off on hacking forums to compete with the fanciest defacement.
Luckily, these kinds of attacks are usually the easiest to detect and fix. You can find defaced websites from mirror sites, where defacers actively post their new victims.
Website vandalism/hacking is mostly automated. This is a critical element as there’s a common misconception on how attacks are being executed.
Here’s an example of how a web hacker hacks your site:
1 – Web hacker with evil intentions begins with making a list of targets by country and special fingerprinting (Google Dorking). He can use (automated tools available) Google to find for example every website in the Czech Republic with the default WordPress page “Hello World” like this: site:.cz inurl:/hello-world/
2 – Now, with the list of over 5000 WordPress sites, there are many possibilities. He could start fingerprinting (automated) specific vulnerable (outdated) software and try to brute-force the admin account with different combinations (also automated).
In this step, the attacker can already have access to a lot of sites (most of the sites are not frequently updated and lack security measures).
3 – As the last step, it’s all about infecting and using the site as the attacker wishes (khm.. also automated).
The attacker might have hacked your website without ever visiting the site or seeing it with their own eyes.
And yes, you should worry about it. Keep in mind that similarly to the abandoned buildings that get freaky graffiti and tags on the dark corners — it’s just a matter of time when your website gets defaced and infected with malware if you don’t have basic maintenance, security measures and proper monitoring in place.
The problem is big and it is growing with time.
To find out how big of a problem you are facing, who could be better than Google.
Here’s what Google released on their blog at the end of March 2017:
“We’ve seen an increase in the number of hacked sites by approximately 32% in 2016 compared to 2015. We don’t expect this trend to slow down.”— Google
Since there is almost a 1/3 chance that your website is running on WordPress, you should already know that the year 2017, way back, didn’t even start with a positive tone.
Every day about 50 000 sites get hacked. And in most cases, the web developers or website owners don’t even have enough knowledge about what is going on on their site. And every day we still see hackers attacking websites.
