There are many subtle ways that we can use to create backdoors on systems, but the old standby tool netcat can perform this task for us very nicely. One useful set of web-based backdoors can be found in the Web Malware Compilation, m which is also included in recent versions of the Backtrack/Kali Linux distributions n o. A great variety of such backdoors exist for any number of applications, and an attacker with a good knowledge of programming can easily create custom varieties. Jason Andress, Steve Winterfeld, in Cyber Warfare (Second Edition), 2014 BackdoorsĪdding backdoors to a system or application is another method that we can use in order to sustain our access. Although the installation of a backdoor may or may not constitute sabotage directly, it will certainly ease the path for such activities.

An attacker might install a backdoor in order to maintain or ease future access to a system, or a backdoor might be installed by another piece of malware in order to further exploit a machine, beyond the initial attack. While they can be used as a standalone tool, backdoors are often installed as a single component of an attack or a malware package. Such tools might be put in place, in advance of leaving, by former employees in order to give them access after their accounts have been terminated, or they may have been installed by an attacker after compromising a system. Backdoors can be included in an application, either by the application developer or later by an attacker, they can be a freestanding application of their own, such as the command and control interfaces used in the nodes of botnets, or they could be implemented in the hardware or firmware of an actual device.īackdoors, for the purposes of sabotage can allow us access to a system, outside of the restrictions of the normal authentication mechanism, in order to carry out our activities unimpeded. The backdoor recognizes the attacker's request, extracts, and executes the embedded backdoor commands, and modifies the HTTP response to include the command output.Thomas Wilhelm, Jason Andress, in Ninja Hacking, 2011 Backdoorsīackdoors provide us with a method of bypassing the normal authentication process for a given system. Hackers start a connection by sending a special HTTP request to the compromised server. “IISpy uses this channel to implement its C&C communication, which allows it to operate as a passive network implant,” said researchers. IISpy is configured as an IIS extension and can see all the HTTP requests received by the compromised IIS server and shape the HTTP response the server will answer with.

Researchers suspect more servers have been compromised but said that since it is not common for administrators to use security software on servers, visibility into IIS servers is limited.

Investigations unearthed the malware popping up on IIS servers in Canada, the US, and the Netherlands. “We suspect the attackers first obtain initial access to the IIS server via some vulnerability and then use Juicy Potato to obtain the administrative privileges that are required to install IISpy as a native IIS extension,” said researchers.
