Microsoft loses control over Windows Tiles subdomain

Published

on

Microsoft has lost control over a crucial subdomain that Windows 8 and Windows 10 use to deliver RSS-based news and updates to Live Tiles –animated Windows start menu items.

The subdomain (notifications.buildmypinnedsite.com) is currently under the control of Hanno Böck, a security researcher and journalist for German tech news site Golem.de.

Subdomain used by websites to deliver RSS news

The subdomain was part of the buildmypinnedsite.com service that Microsoft set up with the launch of Windows 8, and more specifically to allow websites to show live updates inside users’ Start pages and menus.

To take advantage of this new feature, websites could add a meta tag to their source code that allowed Edge users to pin a web page to the Start page in Windows 8 and the Start menu in Windows 10.

On the client-side, when a Windows user opened the Start page/menu, their computer would read the meta tag on the desired site and then load content inside the live tiles.

However, because the Windows Live Tiles service couldn’t process the multitude of RSS feed formats, ever since its launch, Microsoft recommended that websites use the notifications.buildmypinnedsite.com subdomain to convert their RSS feeds into a special XML format that the Windows Tiles service would parse and create the animated Live Tiles inside the Start page/menu.

Thousands of websites added this meta tag to their code, in the hopes of taking advantage of a new way to reach their readers.

But today Böck said the service no longer works.

“The host that should deliver the XML files – notifications.buildmypinnedsite.com – only showed an error message from Microsoft’s cloud service Azure,” the researcher said. “The host was redirected to a subdomain of Azure. However this subdomain wasn’t registered with Azure.”

Böck registered this subdomain on his Azure account and is currently sinkholing any requests it receives. He also notified Microsoft of the issue but said the company did not reply.

“We won’t keep the host registered permanently. There’s a decent amount of traffic reaching this host and running up costs,” the researcher said.

“Once we cancel the subdomain a bad actor could register it and abuse it for malicious attacks,” he warned.

Any threat actor who takes over this domain can use it to craft malformed XML files that could abuse the Windows Live Tiles service to run code on the computers of users who still have website-based Live Tiles in their Start pages/menus.

Böck is also recommending that websites remove the HTML meta tag from their source code, or provide the specially formatted XML files themselves, without sending users over to the notifications.buildmypinnedsite.com subdomain. Some of the sites using this subdomain include Mail.ru, Engadget, BGR, TenForums, Golem.de, Heise.de, and others.

Key Criteria for Evaluating Unified Endpoint Management

Published

on

Endpoint management is one of the most significant challenges in the enterprise today. An increasingly large percentage of our workforce is distributed and demands flexibility to work wherever they want, whenever they want. We must respond by giving them access to the services they require to do their jobs effectively. The alternative is that we, as a business, will suffer, lose good people, and become less competitive. However, we must achieve this essential access while maintaining security and control of our business’s data assets.

An appropriate endpoint management strategy is key to addressing these issues. Our approach should be holistic and unified, bringing together control of devices, management of applications, security of data, and access controls.

Unified endpoint management (UEM) is the approach to meeting this challenge. It has evolved from traditionally disparate solutions for endpoint management, application delivery, and security into a single platform. This single platform delivers a consistent end-user experience across all devices, applications, and locations while maintaining security and control of data assets. The leading solutions allow us to enroll devices easily into our control, provide support, and ensure constituency and compliance while managing access to our applications and data.

This GigaOM Key Criteria Report describes UEM solutions and identifies key criteria and evaluation metrics for selecting such a solution. The corresponding GigaOm Radar Report identifies vendors and products that excel in this sector. Together, these reports give decision-makers an overview of the market to help them evaluate existing platforms and decide where to invest.

How to Read this Report

This GigaOm report is one of a series of documents that helps IT organizations assess competing solutions in the context of well-defined features and criteria. For a fuller understanding consider reviewing the following reports:

Key Criteria report: A detailed market sector analysis that assesses the impact that key product features and criteria have on top-line solution characteristics—such as scalability, performance, and TCO—that drive purchase decisions.

GigaOm Radar report: A forward-looking analysis that plots the relative value and progression of vendor solutions along multiple axes based on strategy and execution. The Radar report includes a breakdown of each vendor’s offering in the sector.

Solution Profile: An in-depth vendor analysis that builds on the framework developed in the Key Criteria and Radar reports to assess a company’s engagement within a technology sector. This analysis includes forward-looking guidance around both strategy and product.

High Performance Application Security Testing – Cloud WAF Security Platforms

Published

on

This free 1-hour webinar from GigaOm Research features analyst Jake Dolezal and will focus on comparing Web Application Firewall (WAF) security platforms in an enterprise with high performance needs.

This webinar will discuss web application security mechanisms deployed in the cloud. The cloud enables enterprises to differentiate and innovate with microservices at a rapid pace. However, the cloud is just as vulnerable, if not more so, to attacks and breaches as on-premises APIs and apps are. Our focus is specifically on approaches to securing apps, APIs, and microservices that are tuned for high performance and availability. We define “high performance” as companies that experience workloads of more than 1,000 transactions per second (tps) and require a maximum latency below 30 milliseconds across the landscape.

In this webinar, we will reveal the performance tests of security mechanisms on NGINX, AWS, and Azure, specifically: ModSecurity, NGINX App Protect WAF, AWS Web Application Firewall (WAF), and Azure WAF.
