New exploit lets attackers take control of Windows IoT Core devices

Speaking at a conference today, a security researcher has revealed a new exploit impacting the Windows IoT Core operating system that gives threat actors full control over vulnerable devices.

The vulnerability, discovered by Dor Azouri, a security researcher for SafeBreach, impacts the Sirep/WPCon communications protocol included with Windows IoT operating system.

Azouri said the vulnerability only impacts Windows IoT Core, the Windows IoT OS version for devices meant to run one single application, such as smart devices, control boards, hobbyist devices, and others.

The vulnerability does not impact Windows IoT Enterprise, the more advanced version of the Windows IoT operating system, the one that comes with support for a desktop functionality, and the one most likely to be found deployed in industrial robots, production lines, and other industrial environments.

The researcher said the security issue he discovered allows an attacker to run commands with SYSTEM privileges on Windows IoT Core devices.

“This exploit works on cable-connected Windows IoT Core devices, running Microsoft’s official stock image,” Azouri said in a research paper shared with ZDNet.

“The method described in this paper exploits the Sirep Test Service that’s built-in and running on the official images offered at Microsoft’s site,” the researcher said. “This service is the client part of the HLK setup one may build in order to perform driver/hardware tests on IoT devices. It serves the Sirep/WPCon protocol.”

Using the vulnerability in this testing service he discovered, the SafeBreach researcher said he was able to expose a remote command interface that attackers can weaponize to take control over smart devices running Microsoft’s Windows IoT Core OS.

During his tests, Azouri built such a tool, a remote access trojan (RAT) that he named SirepRAT, which he plans to open-source on GitHub.

The upside to Azouri’s SirepRAT is that it doesn’t work wirelessly, as the testing interface is only available via an Ethernet connection. This implies that the attacker needs to be physically present near a target, or compromise another device on a company’s internal network and use as a relay point for attacks on vulnerable devices.

ZDNet has reached out for comment to Microsoft, but we did not receive a response before this article’s publication.

Azouri has presented his research today at the WOPR Summit security conference in Atlantic City, NJ, USA. We’ll update this article in the coming days to include links to the SirepRAT GitHub repo and Azouri’s whitepaper.

The Windows IoT operating system is a free successor of the Windows Embedded project. According to SafeBreach, the OS has the second largest market share in the IoT devices market, with a 22.9 percent stake, behind Linux, which has a 71.8 percent market share.

Work from Home Security

Published

Spin Master is a leading global children’s entertainment company that invents toys and games, produces dozens of television and studio series that are distributed in 160 countries, and creates a variety of digital games played by more than 30 million children. What was once a small private company founded by childhood friends is now a public global supply chain with over 1,500 employees and 28 offices around the world.

Like most organizations in 2020, Spin Master had to adapt quickly to the new normal of remote work, shifting most of its production from cubicles in regional and head offices to hundreds of employees working from home and other remote locations.

This dramatic shift created potential security risks, as most employees were no longer behind the firewall on the corporate network. Without the implementation of hardened endpoint security, the door would be open for bad actors to infiltrate the organization, acquire intellectual property, and ransom customer information. Additionally, the potential downtime caused by a security breach could harm the global supply chain. With that in mind, Spin Master created a self-imposed 30-day deadline to extend its network protection capabilities to the edge.

Key Findings:

  • Think Long Term: The initial goal of establishing a stop-gap work-from-home (WFH) and work-from-anywhere (WFA) strategy has since morphed into a permanent strategy, requiring long-term solutions.
  • Gather Skills: The real urgency posed by the global pandemic made forging partnerships with providers that could fill all the required skill sets a top priority.
  • Build Momentum: The compressed timeline left no room for delay or error. The Board of Directors threw its support behind the implementation team and gave it broad budget authority to ensure rapid action, while providing active guidance to align strategy with action.
  • Deliver Value: The team established two key requirements that the selected partner must deliver: implementation support and establishing an ongoing managed security operations center (SOC).

Key Criteria for Evaluating Privileged Access Management

Published

on

Privileged Access Management (PAM) enables administrative access to critical IT systems while minimizing the chances of security compromises through monitoring, policy enforcement, and credential management.

A key operating principle of all PAM systems is the separation of user credentials for individual staff members from the system administration credentials they are permitted to use. PAM solutions store and manage all of the privileged credentials, providing system access without requiring users to remember, or even know, the privileged password. Of course, all staff have their own unique user ID and password that they use to complete everyday tasks such as accessing email and writing documents. Users who are permitted to handle system administration tasks that require privileged credentials log into the PAM solution, which provides and controls such access according to predefined security policies. These policies control who is allowed to use which privileged credentials when, where, and for what tasks. An organization’s policy may also require logging and recording of the actions undertaken with the privileged credentials.

Once implemented, PAM will improve your security posture in several ways. The first is by segregating day-to-day duties from duties that require elevated access, reducing the risk of accidental privileged actions. Secondly, automated password management reduces the possibility that credentials will be shared while also lowering the risk if credentials are accidentally exposed. Finally, extensive logging and activity recording in PAM solutions aids audits of critical system access for both preventative and forensic security.

Companies always want to enhance their ability to quickly address pressing business needs. Toward that end, they look for new ways to make their IT infrastructures more efficient—and more cost effective. Today, those pressing needs often center around data protection and regulatory compliance, which was certainly the case for Adventist Risk Management. What they wanted was an end-to-end, best-in-class solution to meet their needs. After trying several others, they found the perfect combination with HYCU and Nutanix, which provided:

  • Ease of deployment
  • Outstanding ROI
  • Overall TCO improvement

Nutanix Cloud Platform provides a software-defined hyperconverged infrastructure, while HYCU offers purpose-built backup and recovery for Nutanix. Compared to the previous traditional infrastructure and data protection solutions in use at Adventist Risk Management, Nutanix and HYCU simplified processes, speeding day-to-day operations up to 75%. Now, migration and update activities typically scheduled for weekends can be performed during working hours and help to increase IT staff and management quality of life. HYCU further increased savings by providing faster and more frequent points of recovery as well as better DR Recovery Point Objective (RPO) and Recovery Time Objective (RTO) by increasing the ability to do daily backups from one to four per day.

Furthermore, the recent adoption of Nutanix Objects, which provides secure and performant S3 storage capabilities, enhanced the infrastructure by:

    • Improving overall performance for backups
    • Adding security against potential ransomware attacks
    • Replacing components difficult to manage and support
