  • How to use Powershell in an exploit · rapid7/metasploit-framework Wiki
    PowerShell is a scripting language developed by Microsoft. It provides API access to almost everything in a Windows platform, less detectable by countermeasures, easy to learn, therefore it is incredibly powerful for penetration testing during post exploitation, or exploit development for payload execution. Take Metasploit’s windows/smb/psexec_psh.rb module for example: it mimics the psexec utility from SysInternals, the payload is compressed and executed from the command line, which allows it to be somewhat stealthy against antivirus. There’s only less than 30 lines of code in psexec_psh.rb (excluding the metadata that describes what the module is about), because most of the work is done by the Powershell mixin, nothing is easier than that. The command line will automatically attempt to detect the architecture (x86 or x86_64) that it is being run in, as well as the payload architecture that it contains. If there is a mismatch it will spawn the correct PowerShell architecture to inject the payload into, so there is no need to worry about the architecture of the target system.

  • Painless Immutable Infrastructure with Ansible and AWS | Radify Blog – […] In our blog posts Reducing Infrustration and Immutable Demo Nodes, we talk about our approach to immutable infrastructure and the benefits we have seen from employing this approach. In this article, we explore a practical project example so you can get up and running with immutable infrastructure in less than an hour! […]

  • Provisioning EC2 Hosts with Ansible | Allan Denot – Looking to build EC2 hosts with more consistency? Using Ansible you can easily provision EC2 hosts and put some logic on it to adjust EC2 parameters based on the type of host you are building.
    The easiest way to start is to create a playbook calling the ec2 module with the parameters you want to pass to AWS to create your host. In this post I will show a little more scalable way to do this, where the parameters are variables and you can easily have multiple types of hosts sharing the same playbook and role.

  • Creating Active Directory Accounts – Microsoft stores a quoted password in little endian UTF16 base64 encoded.
  • LVM Loopback HOW-TO | Anthony’s Blog – This is a simple tutorial on setting up LVM on loopback devices, I’ve used it a few times for creating dynamic virtual disks; it came in particularly handy when archiving NEXRAD radar data for my radarwatchd project – using up all your inodes on several hundreds of thousands of 15Kb files doesn’t sound like my idea of fun. Creating a virtual volume with reiserfs was a particularly handy solution in this case.
