How to locate malicious code on a website
If you have strong security you shouldn’t need to worry about malicious code being found on websites. Even if your business is small, strong security can help reduce the chances of you being hacked. However, it cannot guarantee 100% protection. It is important to be able to identify malicious code and what to do in the event that your website is hacked.
First, get rid of any malware.
Malware and malicious codes are variations of a common theme. Malware can be described as malicious code. However, it is malicious code that is repeated with very little variation. This is how anti-malware software detects it. However, it is possible that an anti-malware program will not detect malicious code created by hackers for your site.
Anti-malware protection must be installed on all websites. It is often due to insufficient anti-malware protection that websites and local devices are hacked.
It is important to make sure your website is protected from hackers by installing a website malware scanner. Although different products may have different features, the core of any website vulnerability scanner that is trusted will include an anti-malware scanner as well as a firewall for website applications.
You should make it a priority to purchase a strong anti-malware product with an integrated firewall for all your computers and mobile devices. If hackers can hack your computer to steal your administrator login information , it’s not worth spending the time to protect your website.
Clean up custom code
After you have eliminated all known malware, it is time to clean up any custom malicious code. You might be able to restore from the last backup if you only have a small website. This is not recommended if you have a large website.
Small websites can be hacked quickly. Hackers have very few places to hide. Hackers can easily infiltrate websites as they grow in size. Your backup could become infected over time with malicious code.
There are two options for manual cleaning. You can start over and recreate pages. For simple pages, this can be the best option. Another option is to look at them and remove any malicious code. For complex pages, this may be the easiest option.
If this is the case, your backup might be able to assist you. However, it’s not a perfect backup. However, you can use the backup as a guide to spot differences in code between your current website and the last backup. This will not only speed up your cleanup, but it can also provide insight into the hacker’s methods.
You should not only compare the current site version with the backup. Also, make sure to thoroughly go through all your files and databases looking for signs of malicious code. Unfortunately, this code can be embedded in legitimate code, particularly PHP headers.
It is possible to spot malicious code if you are alert to this. Malicious code tends to be highly encrypted and lacks any comments or helpful information about its function, which is a good thing.
After you have cleaned your website of all malicious code, you can test it to make sure it works. If it’s working, you are probably good to go. If it’s not, you have either left malicious code behind or broken genuine code.
Clean up administrator accounts.
Before you celebrate the success of your website, make sure to take a look at the administrator accounts. You should be able to identify all of them. Delete administrator accounts that you don’t recognize. They can be reactivated later. You can always change your passwords later.
