You have probably heard about hackers, attacks on websites and how much they have specifically increased to WordPress sites. You will have heard how important it is to work on the security of your site and the many products that claim to help you in this. It is definitely a priority issue for everyone and it is worth knowing a little about it. What I will tell you here is about something that we can overlook and is the realization that we are hacked.
Many times, we work to strengthen our security, which is very good. If we are victims of an attack that causes significant losses we have to work on restoring our site and recovering what we have lost. But it also happens that we have been hacked and we have not realized it yet! At that point the sooner we know the better because we can take the necessary measures before it is too late. Here I will tell you a bit about it, how to detect if we have been hacked, what we can do to prevent it and also some measures that we can take against an eventual attack.
What is hacking?
Firstly, the word “hacking” is used to refer to the action of looking for weaknesses in the code of a system in order to forcefully break into it. It is believed that the term began to be used in the 60s when an incident occurred with telephone lines from MIT and Harvard that were used for long distance calls diverting the charge to another facility.
Nowadays, there are many varieties of hacking, as are the means through which it is carried out. Some of the most common today are Trojans, sniffing, denial of service (DoS), phishing, identity theft, among others.
Let’s go now specifically to our terrain, the WordPress platform and what things to pay attention to detect possible attacks.
Make sure you have updated all your plugins and themes
Specifically, in terms of WordPress, the attacks have been growing significantly year after year, so each new version of the platform includes improvements in security that respond to intrusion techniques that are detected. This is why I strongly recommend that you always keep your version updated with the latest available one.
This should also be done with all the plugins and themes that you are using. With this in addition to strengthening security, we will also be improving its features. It is important to eliminate what we are not using, since a disabled plugin, outdated, could be the gateway for an attack.
Last comment on this: you have to take the necessary precautions when updating the products. Make sure you will not lose your configurations and that you will not have compatibility conflicts.
Reinforce your WordPress installation
There are some tasks that you must perform after installing WordPress. You can check my guide on this in this same site. To remember those related to security, we have to change the username “admin”, since it is the one with a large part of WordPress sites, it is the most used by hackers to try to enter your site. Along with this we must also choose a strong password, difficult to obtain with robots. I recommend you use more than 8 characters that include uppercase and lowercase letters along with numbers or special characters.
It is also good to change the prefix of our database tables. By default, all tables start with the prefix “wp_”, so hackers will know where to look to break through them. This can be modified from the script of the host installation.
Identify the source of problems
When something does not work, but we still do not know what the cause is, we can start looking for where it originates. If something in the plugins is not what you expect, you can try to deactivate them and see if the failure persists. If not, you will have found the root of the problem.
The same can happen with a particular issue, you can try activating a different one to see if the fault disappears. Once we have found where the malfunction comes from, we can move on to look for possible solutions.
Scan your site
This is the direct action to look for attacks. There are several ways to do it, each with different analyzes and types of results. Some of them are:
The site ” Is it hacked? “It offers a free analysis as well as a monitoring service to which we can subscribe.
Another site that offers a free analysis is Sucuri. It also has much more complete payment tools.
Some free plugins perform various analyses such as “Wordfence Security” or “Anti-Malware”, where they look for files that have been modified or need updating, as well as cleaning of possible infections.
Consulting your hosting service is another possible measure, many of them offer some measures or tools for scanning and searching for infections.
Hire third-party services
When the problem definitely exceeds us, we can always get help from outside help. There are many companies and services that offer recovery, cleaning and disinfection against attacks. It is also possible to hire reinforced security measures or periodic analyses.
This is a point to consider also when choosing a web hosting service. Not all have the same security on their servers, so if this is another aspect to consider against repeated attacks. We are very clear that security is one of the main concerns, that is why we have services that make us more reliable and secure, so it is an excellent option to host your website.
