Kali Rolling ISO of DOOM, Too.

A while back we introduced the idea of Kali Linux Customization by demonstrating the Kali Linux ISO of Doom. Our scenario covered the installation of a custom Kali configuration which contained select tools required for a remote vulnerability assessment. The customised Kali ISO would undergo an unattended autoinstall in a remote client site, and automatically connect back to our OpenVPN server over TCP port 443. The OpenVPN connection would then bridge the remote and local networks, allowing us full “layer 3” access to the internal network from our remote location. The resulting custom ISO could then be sent to the client who would just pop it into a virtual machine template, and the whole setup would happen automagically with no intervention – as depicted in the image below.

Kali NetHunter 3.0 Released

NetHunter has been actively developed for over a year now, and  has undergone nothing short of a complete transformation since its last release. We’ve taken our time with v3.0, and the results are a complete overhaul of the NetHunter Android application, with a more polished interface and a fully functioning feature set.

Through the amazing NetHunter community work led by  binkybear, fattire, and jmingov, we can now proudly look at NetHunter and confidently consider it to be a stable, commercial grade  mobile penetration testing platform. And so, we are really excited with todays release of NetHunter 3.0 – let the games begin!

What it means to be an OSCP

When a student earns an Offensive Security certification such as the OSCP, it is a testament to the personal investment they have made as part of a commitment to excellence.

Saying this, there are some hard truths behind the path to OSCP.

MASSCAN Web Interface

A couple of weeks ago, we had the opportunity to scan and map a large IP address space covering just over 3 million hosts. Our tool of choice for this was the fast and capable masscan, which is packaged in Kali. While masscan has several convenient output formats, such as binary and XML, one feature we were missing was an easy way to search our results. We quickly whipped up a little web interface that would allow us to import and search within a masscan XML output file. This feature proved very useful for us – as once we identified a specific vulnerable pattern on a machine, we could easily cross reference this pattern with over the millions of discovered hosts in our database.

Kali 2.0 Dojo Black Hat / DEF CON USA 2015

Last years event was a rousing success, with many attendees staying all day long and working through the multiple exercises. We had such a great time, we wanted to do it again. This is a great chance to get hands on with Kali 2.0, learning the cutting edge features and how to best put them to use. In this two session workshop series, we will be covering how to create your own custom Kali ISO that is tweaked and modified to exactly fit your needs. This will be followed up in the second session with a hands-on exercise of deploying Kali on USB sticks so that it contains several persistent storage profiles, both regular and encrypted – including the LUKS nuke feature.

What’s New with Exploit Database?

New Features in the Exploit Database

Over the past 6 years, we have been maintaining and updating the Exploit Database on a daily basis, which now boasts over 35,000 exploits. While we constantly work on improving our back-end and entry quality. Over the years there haven’t really been any updates to the front-end, which has traditionally stayed ominously dark and foreboding. As you may have already seen this changed about two weeks ago, with the introduction of the new and improved Exploit Database website.

Booting Kali Linux Live Over HTTP

Kali Linux Features

Here at Offensive Security, we tend to use Kali Linux in unconventional ways – often making use of some really amazing features that Kali Linux has to offer. One of these interesting use-cases includes booting instances of Kali Linux Live over HTTP, directly to RAM. We realized there’s little documentation around this feature and thought we’d shed some light on it so others may enjoy this feature as well.

Booting Kali Over HTTP – Overview

The basic premise involves using the Kali Live kernel and initrd for booting,

Kali Linux on a Raspberry Pi (A/B+/2) with Disk Encryption

With the advent of smaller, faster ARM hardware such as the new Raspberry Pi 2 (which now has a Kali image built for it), we’ve been seeing more and more use of these small devices as “throw-away hackboxes“. While this might be a new and novel technology, there’s one major drawback to this concept – and that is the confidentiality of the data stored on the device itself. Most of the setups we’ve seen do little to protect the sensitive information saved on the SD cards of these little computers.
