Watch out for the backdoors.

backdoors

Once your website has been hacked, it’s most common for the hacker to be able to access your site again in the future, and this is through a website backdoors.

This basic knowledge is necessary if you are a web programmer or have a website; not knowing it could be the source of many headaches if you’re victim of one; because there is nothing worse than having a problem and not knowing what’s exactly happening. Backdoors in general are very common. If you don’t know about them; you could clean your device or website; but not get rid of these terrible things.

What is a backdoor?

Before proceeding to the main topic; you must first understand what a backdoor is.

Imagine a secret entrance at the back of your house that allows you to enter the building without the need for a key to open the front door lock. Well; more or less that would be a backdoor in computing: a secret entrance; vulnerability in the system that allows you to access a website, server; local or business network by skipping the authentication step.

This opening that allows the entry to the system by trespassing its security can be present on purpose; that is, it exists because the programmer has decided so, for several reasons, in fact; not all of them malicious. One may decide to leave that security hole in one’s own computer as a measure to facilitate access to it in an emergency.

Of course; backdoors intentionally left in a system can have a criminal purpose; such as being able to access a computer without permission moments after selling it; and have control of it from a distance.

In other cases; a backdoor exists in a system as part of a programming mistake. That is; during the process of composing the security network of a given system, a breach may have been inadvertently left in the system; leaving an entry undefended, unknown by simple negligence. This type of accident can be very dangerous; as a “committed” attacker could discover it and take advantage of it.

In addition to these two types of backdoors; both of which have been present in the system since its creation; there are the most dangerous backdoors, the artificial backdoors; which are installed in computers to create secret access to systems for malicious purposes. In other words, backdoor malwares.

Backdoor malwares

Backdoor malwares are those malwares that are installed in the system with the aim of creating a secret entry into the system; with which it’s then possible to control it remotely and without restrictions. That is; from the inside it creates a security hole in the system; so that it’s possible to attack it on a larger scale later.

It differs from a Trojan virus in that the backdoor malware only opens the way for subsequent attacks. In a sense; backdoor malwares pave the road for attacks with Trojan malwares; which is why they are the type of malware that works in tandem with Trojan malwares.

Back doors can be created and installed in any software; from complete operating systems to specific applications. And knowing this; I can now move on to the main topic, which is the website backdoor.

Website backdoors

Let’s say you have a website; and at some point this was infected. And no matter what you do, it gets hacked over and over again, every time. You do the clean-up, you get your website back; but it’s attacked again and you have to clean it up one more time. Why does this happen? Very simple: the attacker has left a website backdoor; a secret entrance so that they can regain control at any point in the future of your site; regardless of whether you have carried out a cleanup.

Conventional cleaning doesn’t manage to remove the website backdoors, since they are very well hidden. Most often they’re hidden inside the website code, pretending to be non-malicious code; so it’s not easy to recognize them. However; it’s clear that there must be a website backdoor as your site is infected all the time, and this is a serious problem as it can have a significant negative impact.

 Negative impact of a backdoor on your website

If you are under the influence of a website backdoor; you must act quickly and not give up due to the impression that the only option is to quit because the cleaning has failed. Leaving your website infected will only lead to the death of your domain; for the following reasons:

  • The attacker will send spam emails to all users of your website.
  • Your site will be slowed down considerably since the hacker will use your server to store all kinds of files on it.
  • They’ll remove your ads, display their own ads and profit from the clicks of your visitors.
  • The traffic on your site will be decreased since your visitors will constantly be redirected to other websites.
  • There will be numerous pop-ups on your website asking your visitors to download software onto their computers, cell phones or tablets.
  • Private information, such as credit card information or similar, could be stolen.
  • Once it’s discovered that your website is hacked, it will be blacklisted and eventually suspended.

To avoid each of these problems which; as I said, only lead to your website’s extinction, you must then get rid of the website backdoors. This is the only way to save your site.

But now we come to the problem of the issue; how do you get rid of the website backdoors of your site?

Closing the backdoors forever is easy

Since a website backdoor is hidden within your site’s code; in theory it would be enough to just check the code and delete the door; but there are two obstacles; if you don’t have any knowledge of web programming and coding; you could delete an authentic component of the code; thus creating serious problems. On the other hand; even if you had such notions; you would need an intimate and detailed knowledge of your site’s code to identify any malicious additions; and this is undoubtedly difficult, it would require at the very least an infallible memory on your part.

So reading the code from start to finish looking for the door is not practical; so you must take another measure. And what is that? In a sense; the same one you would have to take with backdoor malwares.

If your computer is affected by a back door virus; all you have to do is install the appropriate antivirus and let it do the job; it will delete all back doors of this type from your device.

In the case of your website; the option left to you is to install a very good security plug-in on it. In a matter of minutes; it will clean up your entire website and rid you of those vermin called website backdoors.

Next comes prevention; to increase your site’s defenses so that something like this doesn’t happen again. Start with the basics; such as activating a firewall on your website, keeping it updated; and strengthening the security of your login page with a captcha; for example.

And just like that you get rid of the backdoors; which can be a real hellhole for you.

Concluding

However; as we have already seen the importance of having security against the back doors, it is really important. This decision could save many of the data, documents and important information that we want to keep protected; so follow these tips to have the best solution for your computer security. So; if you need more information about how to keep yourself protected from the backdoors; don’t hesitate to contact the team.
