How to recover your hacked WordPress blog or website 

                                      

WordPress is one of the most popular content management systems at present. and at same time it is Most targeted as well. so today i will teach you some tips and Methods on how to patch/recover your site when your website is hacked (which is hosted on WP) and this post is also for those who want to keep there WordPress sites safe.

How to recover Hacked Wordpress website 

if your WP website is attacked then follow these steps and get your site back.

Backup - if your website is infected to a small extent then it is still much necessary for you to secure the backup of your website before waiting to see your things changing to worse.you can use Plugin called BackupBuddy for this purpose but, i advice you to use UpdraftPlus Backup because it is free plugin and best alternate of Backupbuddy.

Change Login Details and Secret Access Keys – at the time you feel or see that your site is defaced then immediately check whether your login details are changed or not because some hackers didnt change login details in hurry. so if hacker did'nt changed your login details then quicky change login details and Wp-config secret access keys too.

Running scanners - The scanner are basically used to identify compromises at database level You can try out Cloud Sites WP Scanner plug-in or Sucuri Malware Scanner. After running the scanner you can proceed to next step.

                                                 


Installing Your WordPress Again – Next important step involves Deleting all the files existing in the directory of WordPress except wp-config.php file and wp-content directory. After that you need to download and install a totally fresh copy of WordPress.

Review content folder - check all the folders in wp-content directory if you feel some folder does'nt belong to your site or seems sespicious then remove it , dont worry if you mistakenly removed any folder which is part of your blog and is not suspicious then you can get it back through backup files after even removing.

Review Plug-ins - Now this is time to analyza all your plug-ins simply remove all plug-ins from your Panel which you did'nt use and other plug-ins which you need should be uninstalled and INSTALLED again for security purposes.

Check your .htaccess file for hacks-  Hackers can use your .htaccess to redirect to malicious sites from your URL. Look in the base folder for your site, not just your blog's folder. Hackers will try to hide their code at the bottom of the file, so scroll down. They may also change the permissions of the .htaccess file to stop newbies from editing the file. Change the permissions back to 644.

Now analyze your theme-  task of removing the extra themes which are not in use currently. Next task again involves reviewing your activated theme. Look through the PHP or Javascript code to find out any suspicious activity there. Most of the time hackers make such malicious changes in header.php or footer.php files.

The question is that what is Payload or vector?

So here I have taken a one example of vulnerable website

 Ethical Hacking is very important part for the website and other domain. Now a day’s Hacker easily access on the website. With the common mistakes of developer’s, website owner has been in trouble. As I am security Researcher I have also found 1000 of security flaw in website. I have reported it. Like Microsoft, opera, adobe, Nokia, Braintree, soundcloud, eBay. But now a day’s Hackers easily access on website database. But in the same way Ethical hacker’s (Security Researcher) or white hacker’s done the job. And save the website from the black hat hacker’s. There are lots of security flaws (vulnerability) in website. According the open web application security project (OWSAP) there are lots of security flaw in website. This is top ten security flaw as follow 

A1 – Injection

Injection flaws, such as SQL, OS, and LDAP injection occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing unauthorized data.

A2 – Broken Authentication and Session Management 

Application functions related to authentication and session management are often not implemented correctly, allowing attackers to compromise passwords, keys, session tokens, or exploit other implementation flaws to assume other users’ identities.

A3 – Cross-Site Scripting (XSS)

XSS flaws occur whenever an application takes untrusted data and sends it to a web browser without proper validation or escaping. XSS allows attackers to execute scripts in the victim’s browser which can hijack user sessions, deface web sites, or redirect the user to malicious sites.

A4 – Insecure Direct Object References

•A direct object reference occurs when a developer exposes a reference to an internal implementation object, such as a file, directory, or database key. Without an access control check or other protection, attackers can manipulate these references to access unauthorized data.

A5 – Security Misconfiguration

Good security requires having a secure configuration defined and deployed for the application, frameworks, application server, web server, database server, and platform. All these settings should be defined, implemented, and maintained as many are not shipped with secure defaults. This includes keeping all software up to date.

A6 – Sensitive Data Exposure

Many web applications do not properly protect sensitive data, such as credit cards, tax ids, and authentication credentials. Attackers may steal or modify such weakly protected data to conduct identity theft, credit card fraud, or other crimes. Sensitive data deserves extra protection such as encryption at rest or in transit, as well as special precautions when exchanged with the browser.

A7 – Missing Function Level Access Control

Virtually all web applications verify function level access rights before making that functionality visible in the UI. However, applications need to perform the same access control checks on the server when each function is accessed. If requests are not verified, attackers will be able to forge requests in order to access unauthorized functionality.

A8 - Cross-Site Request Forgery (CSRF)

A CSRF attack forces a logged-on victim’s browser to send a forged HTTP request, including the victim’s session cookie and any other automatically included authentication information, to a vulnerable web application. This allows the attacker to force the victim’s browser to generate requests the vulnerable application thinks are legitimate requests from the victim.

A9 - Using Components with Known Vulnerabilities

Vulnerable components, such as libraries, frameworks, and other software modules almost always run with full privilege. So, if exploited, they can cause serious data loss or server takeover. Applications using these vulnerable components may undermine their defenses and enable a range of possible attacks and impacts.

A10 – Unvalidated Redirects and Forwards

Web applications frequently redirect and forward users to other pages and websites, and use untrusted data to determine the destination pages. Without proper validation, attackers can redirect victims to phishing or malware sites, or use forwards to access unauthorized pages.
