Everybody knows that security is one of the principal things in a website, but seems to take no heed to that. Nevertheless, not only the business sites but personal blogs also have to pay attention to the security issues. Malware (malicious software) always be on top of that. No one wants their site to be attacked, destroyed, or leak user information. Detect all the malware or reduce the number of security gaps will save your WordPress site. Let’s see how.
What is Malware?
Malware stands for malicious software. As an IT specialized terminology, malware means any software intentionally designed to damage a computer system, network, server, including website, and harm computer users. It is implanted or introduced in some way into the object. Malware usually is in the form of executable code, script, or other forms of data.
We also might know it in the name of virus, worm, trojan, ransomware, spyware, adware, and so on. It definitely bad when malware infects your website. In most cases, malware either destroy the website or steal its user information.
Why is your WordPress site infected with malware?
Something can create a favorable situation for hackers to inject malware into your WordPress website. The following are some of them.
Use themes or plugins from untrusted sources
Most of the untrusted technology products, which are from the unverified source, have backdoors created by the hackers, then they can control your site from these backdoors. So, don’t try anything has no clear origin to keep your site safe.
If you tend to use a nulled WordPress theme, stop doing that. Don’t let it harm your site. One more tip for you, if you are looking for a trusted WordPress theme, follow this instruction to make sure that the WordPress theme does not include any malware.
Do not update WordPress, themes, and plugins
Technology turns every day. Hackers improve their skills and ruses all the time. As a result, something may be safe today, but tomorrow. It’s right for all the technological products, including theme, plugin, website, computer, application, even WordPress.
That’s why reputable providers always try to fix and eliminate security bugs in the new version having a higher security level. Why do you not follow your providers to protect your WordPress site?
Use simple username and passwords
Have you heard about Brute Force Attack? Hacker uses software to guess your passwords or PIN codes to gain access to your website and install malware.
If you use simple passwords, it is pretty easy to guess, isn’t it? Our advice is that you should not set the admin account in the name “admin” as well as use any simple passwords for your root accounts.
Do not install any security plugin
There are many signs to make suspicion that malware is inspecting your website. It might be:
- Slower loading speed in both frontend and backend;
- Size of the database is increased abnormally. Such a weird situation when there are a few contents but heavy database;
- Automatic redirect to unknown websites.
Even when they happen on your site, you may not be sure that malware caused it. In addition, malware sometimes exists on your site without any obvious sign. So, you need a tool to detect and notify you of malware injection. Use a WordPress security plugin is a good choice to help you do that.
