    Kali Linux on a Raspberry Pi (A/B+/2) with LUKS 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. This fact, together with a nudge from friends is what prompted us to create a LUKS encrypted, NUKE capable Kali Linux image for our Raspberry Pi devices. The following blog post describes the process, so you can repeat it and make your own shiny shiny.

    Offensive Security Infosec Certifications in the Job Market

    A couple of weeks ago we published our comic Try Harder song, praising the OSCP certification and our students in general. It was really well received by our alumni, who related closely to the the theme of “Try Harder”. However, there is a more serious undertone to this than meets the eye.

  • Multiple Persistent Usb Stores

    Kali USB – Multiple Persistent Stores

    One of the markings of the 1.0.7 Kali release was the introduction of Kali Live USB LUKS encrypted persistent storage, on which we further elaborated in one of our previous blog posts. However, we’re not done yet with USB persistent storage as more features in Kali remain to be explored. The feature we will discuss today boasts the ability to have multiple persistent USB storages which you can choose from at boot time. These multiple persistent storages can be either encrypted, or unencrypted, and can be chosen at boot time using the persistence-label boot parameter.

    NetHunter 1.1 Released

    With the opening shots of 2015 fired, we are happy to make some announcements in the NetHunter arena! One of the things that excite us the most about Kali Linux is how our Kali projects always end up being greater than the sum of their parts. This is most evident in our Kali NetHunter Project – the first open source Android based penetration testing platform for Nexus and OnePlus devices. Wait, OnePlus phones? Yes! Our new NetHunter v1.1 release brings with it some great news – and so we begin.

    Professional Penetration Testing Labs

    For the past few months, we have been quietly beta testing and perfecting our new “Offensive Security Penetration Testing Labs”, or as we fondly call it, the “Offsec Playground”. Today, we are proud to unveil our hosted penetration testing labs – a safe virtual network environment designed to be attacked and penetrated as a means of learning and sharpening your penetration testing skills. The new design of the “Offsec Playground” includes multiple interconnected subnets with a wide array of modern operating systems, including Active Directory domains, Citrix systems, corporate Antivirus solutions as well as Intrusion Prevention Systems which attackers must learn to cope with.

  • Drive Droid Kali Nethunter

    Bypassing Windows and OSX Logins with NetHunter & Kon-boot

    The Kali Linux NetHunter platform has many hidden features which we still haven’t brought to light. One of them is the DriveDroid application and patch set, which have been implemented in NetHunter since v1.0.2. This tool allows us to have NetHunter emulate a bootable ISO or USB, using images of our choosing. That’s right, you can use NetHunter as a boot device which holds a library of bootable ISOs and images…And so we begin:

    Disarming and Bypassing EMET 5.1

    Last week Microsoft released EMET 5.1 to address some compatibility issues and strengthen mitigations to make them more resilient to attacks and bypasses. We, of course, were curious to see if our EMET 5.0 disarming technique has been addressed by the latest version of the toolkit.
