Write your own SSHD backdoor | The Good, The Bad and the Insecure. This article is not written by me. I found it online, but only in one place so this is effectively a mirror for it.

Well this is one of the first tutorials I will write. [What is OpenSSH] First I’m going to tell what OpenSSH does, I’m not getting into details , because most of you guys are probably not even reading this section.
[The Backdooring] We are downloading the sourcecode first. In this tutorial I will explain how to ‘hijack’ the authentication method. Untitled. Web-malware-collection - Collection of web application backdoors and malware, in PHP, JSP, ASP, etc. UPDATE: We have moved from SVN to tarballs you can download due to one of the issues. Basically, after I was forced to hard-reset the SVN for my web-backdoors-collection I realized "backdoors" was only one half of the story. There are FAR more nasty things out there than just backdoors... The new updated version of it (v3 now!) PHP/ASP/JSP Backdoors/Other, "DoS Scripts" Scanning scripts Bots that are found spreading via Web App Vulns And "eratta" - random nasty things we find in our webroots. Warning: Files on this project MAY be (are certainly) malicious. Homepage for project: Attacking webservers via .htaccess - Just Another Hacker. A while back I was testing a CMS that had a curious feature, all uploaded files were placed in their own directory.
This was not a security enhancement as the application allowed php files to be uploaded. However I coudn't help ask, what if php uploads had been restricted? The answer was .htaccess files. Using SetHandler in a .htaccess file is well known, but does not lead to remote code execution. So after some thinking I put together some self contained .htaccess web shells. I wrote both a php and a server side include shells, but other options can easily be added (jsp, mod_perl, etc). This works by first diverting the default apache .htaccess access restriction from within the .htaccess file so we can access it as a url.
Simply upload the preferred shell as a .htaccess file and then visit the .htaccess file via the url. BZShell - ASP.NET Web Shell - GraBBerZ.CoM - ICQ | Proxy | Бруты | Дедики | Эксплоиты. [VB.NET] BZShell. Team. A Backdoor in the Next Generation Active Directory. At the beginning of the last year, I already raised the issue of post-exploitation in a Microsoft Active Directory domain. The brought forward approach addressed the variant aimed mostly at the case of the loss of admin privileges rather than their exploitation. Additionally, the action of regaining the privileges itself involved conspicuous events and visually evident manipulations in the directory. In other words, to regain admin privileges one had to become a member of the appropriate security group, such as Domain Admins. It should be mentioned that administrators get very nervous when suddenly they realize there is someone else in the system.
Some of them rush to address the security incident horse and foot, sometimes taking most unpredictable steps;)) Now imagine how an Active Directory administrator of a large company can react when they see an unfamiliar account name in the Enterprise Admins security group. So how can a pentester remain unnoticed in Microsoft networks?
End If. Small Python Backdoor. Hookworm: A Stealth PHP Backdoor. WeBaCoo Web Backdoor Cookie. [pdf] PHP shells & obfuscations. Anti Alphanum PHP Shell | Ack Ack. Pwnshell – a better jsp shell - omg.wtf.bbq. What do you do when you have an arbitrary file upload to a web-accessible directory in J2EE? Obviously, you need a JSP shell! But there’s one problem: the available ones are kind of terrible. The Metasploit reverse shell is only intended to serve as placeholder for an already-owned box. The world needs a JSP shell that really helps a blackbox attacker pivot to important assets, so I took a stab at it. It’s called quite lamely called pwnshell.
What is it? A single JSP file, embedded with jQuery and everything else you need to make an awesome web shell. How do you use it? Where does it work? Why would you use it? Here’s a video: Finally, some screenshots of the shell in action. The next screenshot shows the help screen (type ‘help’) and the execution of a system command, ‘netstat’: The last screenshot shows the shell’s autocomplete functionality.
If you can think of anything cool to add, let me know. Blog » Hacking with JSP Shells. Most enterprise datacenters today house at least a few web servers that support Java Server Pages (JSP). In my experience, at least one will suffer from vulnerabilities that can be leveraged to upload JSP shells and execute arbitrary commands on the server (this especially seems to be the case with preconfigured appliances). In this blog, I’ll provide two JSP shell code examples and outline five common upload methods that can be used to get the shells onto vulnerable servers in order to execute arbitrary system commands.
JSP Shell Options For those of you who are not as familiar – when I use the term “JSP shell” I’m referring to a “Java Server Page” that accepts arbitrary commands for execution on the hosting web server. Examples of servers that support such technology include jBoss, IBM WebSphere, BEA WebLogic, and Apache Tomcat (just to name a few). Basic JSP shell This is one of the most basic JSP shell code examples available. Enter the command in the input box and click “Execute”. <?
