So, what is a 404 page? It basically tells you that the server cannot find the website page you’re looking for. However, instead of using the 404 error page by default, you can create one. Here’s how it’s done.
First, you need your .htaccess file that should be in the directory of your Web server where you have hosted your pages. If you cannot find, you have to create one. You’ll probably have to contact your hosting support to ask them how to create it or edit it. You might want to use a text editor and then upload it to the server, or create and edit directly from the server tool they use.
Once you have the .htaccess file created and edited by adding a line like the following:
ErrorDocument 404 https://www.esds.co.in/404page.php
Now that the line in the .htaccess file points to the error page we create. This is just an HTML document. Once you’ve created, save it and call 404page.php or html as per url structure. The next step is to upload the .htaccess file to the server and the error page.
Once you are located in the corresponding directory we have to get it going. We do this by changing the attributes CHMOD to 644. You can do through a Telnet or FTP program of your choice. If you connect via Telnet and do it via command, you must type the following:
chmod 644 .htaccess
Now you must try if it works. Simply type your domain in the browser points to a page that does not exist, and you should see the 404 error page. If not, make sure the CHMOD is configured correctly, and if you still have problems, your Web hosting company can surely help you.
BCC is a function used in emails and have an interesting purpose in some cases. An average email recipient has three classes, the first is the usual “To” recipient “CC” and finally the “BCC”. The first one is intended for the main recipients of the email, the second is for those recipients who are to receive a copy of the mail, and finally, the BCC who will receive a copy of the email but their email will not be seen by the other recipients. The usefulness of the BCC is to allow a long list of people interested in receiving the email, but for some reason they want to remain hidden.
The “To” field is for sending mail to people who are active in a project or subject of the email. This field addresses all visible together by interest of the email. This is because it is assumed that all are related to work and therefore have to keep in touch. On the other hand, the “CC” field are people who will not directly addressed email, and can also be interesting to know their e-mail each other.
The “BCC” field may be people who are related in some way to the job or project, but it is not essential that your email addresses are known. This can be for several reasons. The most common use for the primary recipient does not know who is receiving a copy of the email. While this can be done easily by a second copy of the message body and by forwarding the BCC field allows us to do this in a simple way and in a single step.
The BCC recipient will see the main direction on who is sending the mail (the “To” field), but the main target will see it is the only one who is sending the email. In mailing lists, the BCC camp is normally used as a courtesy for individuals who are part of the list. Even if everyone agrees to share your e-mail, have a mailing list too long is a risk of spam. It is also a risk for the subject of certain viruses, which include all the email addresses to replicate. The BCC field stops get all directions.
The meaning of BCC is Blind Carbon Copy, and is a term that predates the computers we know. At other times, when letters were written, it was done alternating pages of carbon paper between normal paper where it was written. When writing a letter several copies were made. Addresses and greetings were often left blank during the carbon copy, and then added by hand later. In this way the recipient does not know who else was receiving the letter.
This simple tutorial will explain how to create an email auto-responder in cPanel. For the setting to work you must have an email address created in cPanel.
Auto-responders will send a pre-generated message to anyone who sends an e-mail to an e-mail configured. To make the configuration of Auto-Response in cPanel follow the steps below:
Click Create / Modify.
And voila! Your autoresponder is configured.

First thing to do in these cases is to calm down and read this post from beginning to end, not only just read the part that most interests you or the part that you “think” that will solve your problem, but you must first understand how to identify the type of invasion because of which your site has suffered and finally work to solve and prevent this problem from occurring again in the future.
What kind of invasions are there?
There are several types, some of them are follows:
Logically there are other ways because of which a malicious user with sufficient knowledge in web programming and hosting invade your web site (regardless of platform and hosting used), such as invasion through folders with permissions 777, but everything is a matter of lack of attention or even failure of security by the user or developer.
What are hidden or encrypted malicious code?
Malicious codes are usually hidden within random PHP files, because of which your website has security flaws where the malicious user can invade at any time because of which he gets access to your database and FTP files, most malicious codes are encrypted by the eval () function, this helps them in finding the loop holes. Just because most web sites have a proper or secure open system (open source), does not use encryption in PHP code. Many users of CMS systems such as Joomla, WordPress and others are the main victims of this type of invasion, because these CMS systems are free and widely used by Most developers or administrators of web sites, then malicious users distribute their malicious code usually using templates, modules and plug-ins for the other users to download on the internet.
This never happened before, why only now?
Many users and administrators who have hacked web sites (invaded) by malicious code, ask themselves, “But I use this platform for years and never had this problem before, why only now?” Or also have the question: “I have several web sites with the same files and the same system, why only a particular site has been hacked and the other not?”. The answer to these two most frequently asked questions is very simple, everything works perfectly until the problem occurs, be it invasion or other ie, nothing works forever, therefore, to use a system that has malicious code you are vulnerable to being hacked and this invasion may occur at any time, or may also be that ever occurring. The malicious users generally use search engines like Google to find what type of website vulnerability is this, they have their own ways of finding the vulnerability, ie, every site that has malicious code and are registered in search engines, are easily found by the invaders and become easy targets, then we can understand why some websites are hacked and not others, even using the same files allegedly containing malicious code, sites that have better placement in search engines are the first to be invaded, some intrusions are made silently just to steal important data and no damage is caused to the web site system, besides being other invasions to steal the data end up damaging the system of web site and purposely leaving a message to the administrator.
How do I identify the kind of invasion that my site is suffering?
Simple… If you have a web site developed in Joomla, Word Press or even other ready CMS platforms or BLOG, the first steps to identify the type of invasion are:
1. Before taking any hasty concussion that could harm the data that remain on web site, make a BACKUP of the database and also all your FTP files that are on the hacked site.
2. After performing BACKUP, you need to keep your site online and keep the attacker (malicious user) continue to have access to your files and database, regardless of the type of intrusion that your site is experiencing, first check with a qualified professional in the field of viruses and trojans to do a scan on your computer in order to find viruses or trojans, then change all your passwords, including cPanel, database where your site is configured, FTP passwords and mainly the password for all administrators who have access to the site because of no use you make all the changes of passwords and forget the passwords of the site administrators, that surely the malicious user (attacker) already has, and if not changed facilitated invasion of a new site.
3. Now you need to change the address of the public_html folder which is located inside the main folder of your FTP: public_html_website_data, example: suppose I have ESDS Hosting and cPanel is my login: login:
Then I will change the folder / login / public_html to / login / public_html_old
That is done, all attempting to access my site will not be able to access the site(is unavailable), due to the default HTTP system folder was changed, as our goal was to leave the files on the site unavailable to prevent further damage until the type of invasion is identified and proper solution outlet, go to the next step.
4. As yet we do not know what kind of website suffered invasion and also already have some knowledge about the types of intrusions and malicious code are what we will now start looking for these codes, it is not an easy task, because they can be hidden inside any PHP script of your website, first start looking for any PHP script that is not part of your site if your site is on a ready CMS platform like Joomla, WordPress and others, this task becomes easier, just download the original CMS of the same version from official website and compare any php file that is not part of the system, if there are any suspicious file, open it with any text editor and make sure it contains encrypted codes of type eval (anything) or even any other type of encryption, if any function of type eval (), we note that the invasion occurred on your site due to your PHP files in hidden malicious code, but do not think just remove this file and your problem will be solved, besides looking for PHP files that are not part of the system, you need to look inside each file for malicious code, which poses lie hidden in the script, in which there are usually encrypted type of eval (), if you see that your PHP files have improper or malicious files that are not part of your website system, then we can say that the security hole that allowed this invasion occurred on that account.
Found no malicious code into my website, and now?
If you find no malicious code in your PHP files, so everything indicates that the invasion occurred for other reasons, maybe easy password, or maybe your computer was infected by this virus, trojans or even can be a security flaw in your own web site, in which case we recommend contacting a professional in the area of web security, or you can take help of support team by opening a call through the central customer service requesting an aid to our developers and security experts, we put our professionals at your disposal to help you solve any problem, especially when it comes to security flaws, always treat these problems with high priority and you can account with us whenever needed.
I have Identified the type of invasion that my site is suffering, is by malicious code, how do I fix?
To solve the problem you have two options, first would remove all files from your FTP of a web site and do a fresh install of the system used on your web site using system files downloaded from the official website of the developer and not third-party sites, and especially avoid using modules, templates and unknown plug-ins that are not downloaded from the official website, or, before using any third-party code or script to check for hidden malicious code in PHP files before sending to accommodation, following the four steps of verification and identification that you read this post earlier, the second alternative would remove all malicious code that may be hidden in the PHP files and check which file was corrupted and reset again, always using source code directly downloaded from the official website regardless of their platform.
How to prevent many invasions?
First you need to watch out what hosting provider will host your site, do not analyze prices and costs, analyze the quality and safety that the provider offers.
ESDS has several features to prevent this type of invasion, most of our servers by default has additional security that prevents the execution of malicious code in your PHP scripts, you will hardly find this type of protection in other hosting providers, so just for the simple fact that most malicious code can not be executed On the ESDS servers, this is a big step in preventing invasions by malicious code, but even then you have to take some safety measures and prevention. Below you can find some tips and observations that will help you guard against any kind of invasion:
After identifying the type of intrusion your site has suffered, make arrangements to resolve the security flaw and prevent new invasions occur, you can change the name to the correct public_html_old public_html folder again, making your site back up and running for netizens again.
These are the basic tips for identifying and resolving an invasion by malicious code, hope this post has helped you, but if not, feel free to ask for assistance to technical support.
