By examining the hooks that the security software uses we can see what it's likely to intercept, and get a fair idea of its capabilities. This would allow the security system to filter access to every file on the system in real time. Hooking allows them to intercept and check every call that a userspace program might make to a function in the System Service Dispatcher Table (SSDT) - what Windows looks up to see where in the computer's memory each system function resides.įor example, a Host Intrusion Prevention System (HIPS) program might hook the function ZwCreateFile in the SSDT which is the function that is called every time a file is either opened or created. Often antivirus programs use a rootkit technique called hooking. We also looked at how each of the antivirus tools modifies the kernel and userland.

Using CANVAS we tested to see how the security suite would react to different local attacks such as grabbing passwords, installing malicious drivers and hiding processes to cover up an attacker's tracks.

In addition to the vanilla callback we created a HTTP downloader which, when executed, would go to a specified URL to download and execute the newly downloaded file. On the CANVAS side we created a simple callback executable using its BuildCallbackTrojan tool, which is the equivalent of a MOSDEF callback payload that an exploit would use (that is, a program that calls home).

Using the msfpayload and msfencode programs from Metasploit this is easy to do: We then took it one step further by encoding it in various formats designed to obfuscate and encrypt the program's contents, to bypass any installed security. It was then copied via SMB to a VMware virtual machine that had the security suite installed on it, and executed to see if that security suite would pick it up. The gritty detailsįrom within Metasploit we created a simple bind shell program, which would bind to a local port when executed and give a shell to anyone who connected remotely. Not only should these tools be able to show how the antivirus software defends against a targeted attack, but, since the tools use techniques common to viruses and rootkits, they should stress the virus scanners to their limits. We use these products in our day-to-day network penetration tests and for custom exploit development. Both of these tools allow the remote exploitation of systems and come with a huge range of tools and exploits. In addition to our assortment of malware we decided to include a number of files from the Metasploit framework and Immunity CANVAS Professional. Security stretches beyond just protecting your local machine from the world - it needs to protect the world from your local machine too.

Why test Unix files on a Windows machine? A Windows machine may well be the originator of viruses sent to other operating systems, whether through email or another vector.
