The sandbox is a CentOS 6.3 virtual machine image with a pre-configured OpenNebula 4.4.0 front-end, a virtualization host using QEMU ready to execute virtual machines, and prepared images to offer a complete and rich cloud experience. Optionally other physical worker nodes using any of the hypervisors supported by OpenNebula can be enrolled to build small-scale cloud infrastructures. Users are able to log into an OpenNebula cloud, peer the managed resources, and launch instances of virtual machines without the hassle of configuring a physical infrastructure.
I downloaded the HDP 2.3.2 sandbox. Following that I am trying to import the Virual Appliance into the Oracle VM VirtualBox Manager. I keep getting the following errors. The site says the sandbox file is supposed to be 8.5G but the downloaded file is only 2G. Can someone please help? Thanks a lot.

An alternative to software sandboxing, micro VMs rely on hardware isolation to prevent infection from untrustworthy, often user-initiated tasks, such as web browsing or document/media downloading. The concept was pioneered by security startup vendor Bromium, which released its first micro VM product in 2012. Cloud vendor Amazon Web Services (AWS) released the open source Firecracker micro VM in 2018.
The Eclipse Foundation has a long list of IoT-related projects that include standards and development frameworks. The project also offers a wealth of videos, tutorials, sandboxes, and other tools to help new IoT developers get started on their first projects.

The Developer Cloud Sandbox is a Virtual Machine (VM) that provides scientific developers with an Exploitation Platform-as-a-Service (PaaS). It consists of a development environment for processor integration and testing, and a framework for Cloud provisioning.The Developer Cloud Sandbox PaaS allows you to plug scientific applications written in a variety of languages (e.g. Java, C++, IDL, Python, R), then deploy, automate, manage and scale them in a very modular way. The algorithm integration is performed from within a dedicated Virtual Machine, running initially as a simulation environment (sandbox mode) that can readily scale to production (cluster mode). Accessed from an harmonized Shell environment, support tools also facilitate the data access and workflow management tasks.
Repeatable, reboot resilient windows environment installations made easy using Chocolatey packages. When its time to repave either bare metal or virtualized instances, locally or on a remote machine, Boxstarter can automate both trivial and highly complex installations. Compatible with all Windows versions from Windows 7/2008 R2 forward.
Crossplane, a Cloud Native Computing Foundation sandbox project, is an open source Kubernetes add-on that extends any cluster with the ability to provision and manage cloud infrastructure, services, and applications using kubectl, GitOps, or any tool that works with the Kubernetes API.
Docker uses LXC to create and manage native, sandboxed virtual containers. LXC containers acts like a separate OSes, can install their own packages without affecting anything else, and overall have almost the same flexibility of VMs but without any of the virtualization overhead! Docker adds a ton of features, like an elegant configuration file that automates many things (like port forwarding, disk/directory mounting, networking, etc), a way to create and share readymade images that can be distributed as appliances, etc.
Using Hyper-V Manager (or PowerShell), create the following virtual switches (if you are new into Hyper-V, check this documentation on how to create virtual networks: -us/virtualization/hyper-v-on-windows/quick-start/connect-to-network):
The winning submissions to Pwn2Own 2016 provided unprecedented insight into the state of the art in software exploitation. Every successful submission provided remote code execution as the super user (SYSTEM/root) via the browser or a default browser plugin. In most cases, these privileges were attained by exploiting the Microsoft Windows or Apple OS X kernel. Kernel exploitation using the browser as an initial vector was a rare sight in previous contests.
This presentation will detail the eight winning browser to super user exploitation chains (21 total vulnerabilities) demonstrated at this year's Pwn2Own contest. We will cover topics such as modern browser exploitation, the complexity of kernel Use-After-Free exploitation, and the simplicity of exploiting logic errors and directory traversals in the kernel. We will analyze all attack vectors, root causes, exploitation techniques, and possible remediations for the vulnerabilities presented.
Reducing attack surfaces with application sandboxing is a step in the right direction, but the attack surface remains expansive and sandboxes are clearly still just a speed bump on the road to complete compromise. Kernel exploitation is clearly a problem which has not disappeared and is possibly on the rise. If you're like us, you can't get enough of it; it's shell on earth.
Today's software needs to isolate not only processes but the many components *within* a process from each other. Process-level isolation via jails, sandboxes, VMs, or hypervisors is finally becoming mainstream, but it misses an important point about modern software: its growing number of libraries that are all loaded into the same address space, and may all interact with complex inputs by way of vulnerable parsers. A process, even isolated, is as weak as the weakest of its components, but is as valuable as the most sensitive data it holds. Heartbleed was a perfect example of this: a faulty parser in a library could read absolutely everything in memory; there are many others less famous but no better. The biggest challenge of making intra-process memory protection practical is that it cannot require major changes to how software is written. A practical granular memory protection scheme must work for the existing C/C++ build chains, nor should it change the ABI. Further, it cannot rely on concepts that aren't already intuitively clear to C/C++ programmers. Many academic proposals for more granular memory access control stopped short of this. They disregard the glue what keeps the development process and runtime together: the ABI.
We demonstrate ELFbac, a system that uses the Linux ELF ABI to express access control policies between a program's components, such as libraries, and requires no changes to the GNU build chain. It enforces these policies by using a modified Linux loader and the Linux virtual memory system. ELFbac policies operate on the level of ELF object file sections. Custom data and code units can be created with existing GCC C/C++ attributes with a one-line annotation per unit; they are no more complex than C's static scoping. We have developed prototypes for ARM and x86. We used our ARM prototype to protect a validating proxy firewall for DNP3, a popular ICS protocol, and our x86 one to write a basic policy for Nginx. We will also demonstrate a policy for protecting OpenSSH.
Pangu 9, the first (and only) untethered jailbreak tool for iOS 9, exploited a sequence of vulnerabilities in the iOS userland to achieve final arbitrary code execution in the kernel and persistent code signing bypass. Although these vulnerabilities were fixed in iOS 9.2, there are no details disclosed. This talk will reveal the internals of Pangu 9. Specifically, this talk will first present a logical error in a system service that is exploitable by any container app through XPC communication to gain arbitrary file read/write as mobile. Next, this talk will explain how Pangu 9 gains arbitrary code execution outside the sandbox through the system debugging feature. This talk will then elaborate a vulnerability in the process of loading the dyld_shared_cache file that enables Pangu 9 to achieve persistent code signing bypass. Finally, this talk will present a vulnerability in the backup-restore process that allows apps signed by a revoked enterprise certificate to execute without the need of the user's explicit approval of the certificate.
Apple graphics, both the userland and the kernel components, are reachable from most of the sandboxed applications, including browsers, where an attack can be launched first remotely and then escalated to obtain root privileges. On OS X, the userland graphics component is running under the WindowServer process, while the kernel component includes IOKit user clients created by IOAccelerator IOService. Similar components do exist on iOS system as well. It is the counterpart of "Win32k.sys" on Windows. In the past few years, lots of interfaces have been neglected by security researchers because some of them are not explicitly defined in the sandbox profile, yet our research reveals not only that they can be opened from a restrictive sandboxed context, but several of them are not designed to be called, exposing a large attack surface to an adversary. On the other hand, due to its complexity and various factors (such as being mainly closed source), Apple graphics internals are not well documented by neither Apple nor the security community. This leads to large pieces of code not well analyzed, including large pieces of functionality behind hidden interfaces with no necessary check in place even in fundamental components. Furthermore, there are specific exploitation techniques in Apple graphics that enable you complete the full exploit chain from inside the sandbox to gain unrestricted access. We named it "graphic-style" exploitation.
In the first part of the talk, we introduce the userland Apple graphics component WindowServer. We start from an overview of WindowServer internals, its MIG interfaces as well as "hello world" sample code. After that, we explain three bugs representing three typical security flaws: - Design related logic issue CVE-2014-1314, which we used at Pwn2Own 2014 - Logic vulnerability within hidden interfaces - The memory corruption issue we used at Pwn2Own 2016 Last but not least we talk about the "graphic-style" approach to exploit a single memory corruption bug and elevate from windowserver to root context.
The second part covers the kernel attack surface. We will show vulnerabilities residing in closed-source core graphics pipeline components of all Apple graphic drivers including the newest chipsets, analyze the root cause and explain how to use our "graphic-style" exploitation technique to obtain root on OS X El Capitan at Pwn2Own 2016. This part of code, mostly related to rendering algorithm, by its nature lies deeply in driver's core stack and requires much graphical programming background to understand and audit, and is overlooked by security researchers. As it's the fundamental of Apple's rendering engine, it hasn't been changed for years and similar issues do exist in this blue ocean. We'll also come up with a new way of kernel heap spraying, with less side-effect and more controllable content than any other previous known methods. The talk is concluded by showing two live demos of remote gaining root through a chain of exploits on OS X El Capitan. Our first demo is done by exploiting userland graphics and the second by exploiting kernel graphics. 17dc91bb1f
