Joanna Rutkowska (born 1981 in Warsaw) is a Polish computer security researcher, primarily known for her research on low-level security and stealth malware, [1] and as founder of the Qubes OS security-focused desktop operating system. [2]

Career

She became known in the security community after the Black Hat Briefings conference in Las Vegas in August 2006, where Rutkowska presented an attack against Vista kernel protection mechanism, and also a technique dubbed Blue Pill, that used hardware virtualization to move a running OS into a virtual machine. Subsequently, she has been named one of Five Hackers who Put a Mark on 2006 by eWeek Magazine for her research on the topic. [3] The original concept of Blue Pill was published by another researcher at IEEE Oakland in May 2006 under the name VMBR. [4]

During the following years, Rutkowska continued to focus on low-level security. In 2007 she demonstrated that certain types of hardware-based memory acquisition (e.g. FireWire based) are unreliable and can be defeated. [5] Later in 2007, together with team member Alexander Tereshkin, presented further research on virtualization malware. [6] In 2008, Rutkowska with her team focused on Xen hypervisor security. [7] In 2009, together with a team member Rafal Wojtczuk, presented an attack against Intel Trusted Execution Technology and Intel System Management Mode. [8]

In April 2007, Rutkowska founded Invisible Things Lab in Warsaw, Poland. The company focuses on OS and VMM security research and provides various consulting services. In a 2009 blog post she coined the term "evil maid attack", detailing a method for accessing encrypted data on disk by compromising the firmware via an external USB flash drive. [9]

In 2010, she and Rafal Wojtczuk began working on the Qubes OS security-oriented desktop Xen distribution, which utilizes Fedora Linux. The initial release of Qubes 1.0 was completed by September 3, 2012. [10] Its main concept is "security by compartmentalization", using domains implemented as lightweight Xen virtual machines to isolate various subsystems. Each compartment is referred to as a Qube, which operates as a separate hardware level virtual machine. The project refers to itself as "a reasonably secure operating system" and has received endorsements by numerous privacy and security experts. [11] [12] [ failed verification ] It is fairly unique in its capabilities, having a design informed by research on proven vulnerabilities in the trusted compute base (TCB), that are unaddressed in most common desktop operating systems.

She has published seminal works on systems trustability, most recently Intel x86 Considered Harmful [13] and State Considered Harmful - A Proposal for a Stateless Laptop. [14] Rutkowska has been invited as an esteemed presenter at security conferences, such as Chaos Communication Congress, Black Hat Briefings, HITB, RSA Conference, RISK, EuSecWest & Gartner IT Security Summit.

A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed and often masks its existence or the existence of other software. The term rootkit is a compound of "root" and the word "kit". The term "rootkit" has negative connotations through its association with malware.

<span class="mw-page-title-main">Xen</span> Type-1 hypervisor

Xen is a free and open-source type-1 hypervisor, providing services that allow multiple computer operating systems to execute on the same computer hardware concurrently. It was originally developed by the University of Cambridge Computer Laboratory and is now being developed by the Linux Foundation with support from Intel, Citrix, Arm Ltd, Huawei, AWS, Alibaba Cloud, AMD, Bitdefender and epam.

A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the same kernel.

In computing, paravirtualization or para-virtualization is a virtualization technique that presents a software interface to the virtual machines which is similar, yet not identical, to the underlying hardware–software interface.

System Management Mode is an operating mode of x86 central processor units (CPUs) in which all normal execution, including the operating system, is suspended. An alternate software system which usually resides in the computer's firmware, or a hardware-assisted debugger, is then executed with high privileges.

Intel Trusted Execution Technology is a computer hardware technology of which the primary goals are:

Blue Pill is the codename for a rootkit based on x86 virtualization. Blue Pill originally required AMD-V (Pacifica) virtualization support, but was later ported to support Intel VT-x (Vanderpool) as well. It was designed by Joanna Rutkowska and originally demonstrated at the Black Hat Briefings on August 3, 2006, with a reference implementation for the Microsoft Windows Vista kernel.

libvirt Management tool

libvirt is an open-source API, daemon and management tool for managing platform virtualization. It can be used to manage KVM, Xen, VMware ESXi, QEMU and other virtualization technologies. These APIs are widely used in the orchestration layer of hypervisors in the development of a cloud-based solution.

XenClient is a discontinued desktop virtualization product developed by Citrix. It runs virtual desktops on endpoint devices. The product reached end of-life in December 2016. XenClient runs both operating system and applications locally in the end users device, without the need for a connection to a data center, which is why it is used in environments with limited connectivity, disconnected operation on laptops, and other scenarios where local execution is desired while keeping management centralized.

Second Level Address Translation (SLAT), also known as nested paging, is a hardware-assisted virtualization technology which makes it possible to avoid the overhead associated with software-managed shadow page tables.

Hyperjacking is an attack in which a hacker takes malicious control over the hypervisor that creates the virtual environment within a virtual machine (VM) host. The point of the attack is to target the operating system that is below that of the virtual machines so that the attacker's program can run and the applications on the VMs above it will be completely oblivious to its presence.

Intel Software Guard Extensions (SGX) is a set of instruction codes implementing trusted execution environment that are built into some Intel central processing units (CPUs). They allow user-level and operating system code to define protected private regions of memory, called enclaves. SGX is designed to be useful for implementing secure remote computation, secure web browsing, and digital rights management (DRM). Other applications include concealment of proprietary algorithms and of encryption keys.
