Internet Explorer zero-day lets hackers steal files from Windows PCs

Published

on

A security researcher has published today details and proof-of-concept code for an Internet Explorer zero-day that can allow hackers to steal files from Windows systems.

The vulnerability resides in the way Internet Explorer processes MHT files. MHT stands for MHTML Web Archive and is the default standard in which all IE browsers save web pages when a user hits the CTRL+S (Save web page) command.

Modern browsers don’t save web pages in MHT format anymore, and use the standard HTML file format; however, many modern browsers still support processing the format.

An XEE in IE 11

Today, security researcher John Page published details about an XEE (XML External Entity) vulnerability in IE that can be exploited when a user opens an MHT file.

“This can allow remote attackers to potentially exfiltrate Local files and conduct remote reconnaissance on locally installed
Program version information,” Page said. “Example, a request for ‘c:Python27NEWS.txt’ can return version information for that program.”

Because on Windows all MHT files are automatically set to open by default in Internet Explorer, exploiting this vulnerability is trivial, as users only need to double-click on a file they received via email, instant messaging, or another vector.

Page said the actual vulnerable code relies on how Internet Explorer deals with CTRL+K (duplicate tab), “Print Preview,” or “Print” user commands.

This normally requires some user interaction, but Page said this interaction could be automated and not needed to trigger the vulnerability exploit chain.

“A simple call to the window.print() Javascript function should do the trick without requiring any user interaction with the webpage,” he said.

Furthermore, Internet Explorer’s security alert system can also be disabled.

“Typically, when instantiating ActiveX Objects like ‘Microsoft.XMLHTTP’ users will get a security warning bar in IE and be prompted to activate blocked content,” the researcher said. “However, when opening a specially crafted .MHT file using malicious < xml > markup tags the user will get no such
active content or security bar warnings.”

Exploit works on Windows 7, 10, Server 2012 R2

Page said he successfully tested the exploit in the latest Internet Explorer Browser v11 with all the recent security patches on Windows 7, Windows 10, and Windows Server 2012 R2 systems.

Probably the only good news about this vulnerability disclosure is the fact that Internet Explorer’s once dominating market share has now shrunk to a meager 7.34 percent, according to NetMarketShare, meaning the browser is seldom used.

But, as Windows uses IE as the default app to open MHT files, users don’t necessarily have to have IE set as their default browser, and are still vulnerable as long as IE is still present on their systems, and they’re tricked into opening an MHT file.

Microsoft was notified but declined to patch

Page said he notified Microsoft about this new IE vulnerability on March 27, but the vendor declined to consider the bug for an urgent security fix in a message sent to the researcher yesterday, April 10.

“We determined that a fix for this issue will be considered in a future version of this product or service,” Microsoft said, according to Page. “At this time, we will not be providing ongoing updates of the status of the fix for this issue, and we have closed this case.”

Following Microsoft’s firm response, the researcher released details about the zero-day on his site, along with proof-of-concept code and a YouTube demo.

This vulnerability should not be taken lightly, despite Microsoft’s response. Cybercrime groups have exploited MHT files for spear-phishing and malware distribution in previous years, and MHT files have been a popular way to package and deliver exploits to users’ computers.

Because they can store malicious code, all MHT files should always be scanned before opening, regardless of if the file was recently received, or it’s been standing there on your PC for months.

GigaOm Radar for Security Orchestration, Automation, and Response (SOAR)

Published

on

Security Orchestration, Automation, and Response (SOAR) emerged as a product category in the mid-2010s. At that point, SOAR solutions were very much an automation and orchestration engine based on playbooks and integrations. Since then, the platforms have developed beyond the initial core SOAR capabilities to offer more holistic experiences to security analysts, with the aim of developing SOAR as the main workspace for practitioners.

Newer features offered by this holistic experience include case management, collaboration, simulations, threat enrichment, and visual correlations. Additionally, SOAR vendors have gradually implemented artificial intelligence (AI) and machine learning (ML) technologies to enable their platforms to learn from past events and fine-tune existing processes. This is where evolving threat categorization and autonomous improvement become differentiators in the space. While these two metrics are not critical for a SOAR platform, they may offer advantages in terms of reduced mean time to resolution (MTTR), resilience against employee turnover, and overall flexibility.

We’ve observed a lot of acquisition activity in the SOAR space. This was to be expected considering that, after 2015, a sizable number of pure-play SOAR vendors entered the market. Larger players with a wider security portfolio are acquiring these SOAR-specific vendors in order to enter the automation and orchestration market. We expect to see more SOAR acquisitions as the security tools converge, very likely into next-generation Security Information & Event Management products and services (SIEMs).

SIEM is a great candidate for a central management platform for security activities. It was designed to be a single source of truth, an aggregator of multiple security logs, but has been limited historically in its ability to carry out actions. In the past few years, however, SIEMs have either started developing their own automation and orchestration engines or integrated with third-party SOAR vendors. Through a number of acquisitions and developments, multiple players with wider security portfolios have begun to offer SOAR capabilities natively as part of other security solutions.

Going forward, we expect SOAR solutions to be further integrated into other products. This will include not only SIEM, but also solutions such as Extended Detection and Response (XDR) and IT automation. The number of pure-play SOAR vendors is unlikely to increase, although a handful may remain as fully agnostic solutions that enterprises can leverage in instances when their existing next-generation SIEM platforms do not meet all their use cases. However, for pure-play SOAR vendors to remain competitive, they will need to either expand into other security areas or consistently outperform their integrated counterparts.

GigaOm Radar for Disaster Recovery as a Service (DRaaS)

Published

on

Very few organizations see disaster recovery (DR) for their IT systems as a business differentiator, so they often prefer to outsource the process and consume it as a service (DRaaS) that’s billed monthly. There are many DRaaS providers with varying backgrounds, whose services are often shaped by that background. Products that started as customer-managed DR applications tend to have the most mature orchestration and automation, but vendors may face challenges transforming their application into a consumable service. Backup as a Service (BaaS) providers typically have great consumption models and off-site data protection, but they might be lacking in rich orchestration for failover. Other DRaaS providers come from IaaS backgrounds, with well-developed, on-demand resource deployment for recovery and often a broader platform with automation capabilities.

Before you invest in a DRaaS solution, you should attempt to be clear on what you see as its value. If your motivation is simply not to operate a recovery site, you probably want a service that uses technology similar to what you’re using at the protected site. If the objective is to spend less effort on DR protection, you will be less concerned about similarity and more with simplicity. And if you want to enable regular and granular testing of application recovery with on-demand resources, advanced failover automation and sandboxing will be vital features.

Be clear as well on the scale of disaster you are protecting against. On-premises recovery will protect against shared component failure in your data center. A DRaaS location in the same city will allow a lower RPO and provide lower latency after failover, but might be affected by the same disaster as your on-premises data center. A more distant DR location would be immune to your local disaster, but what about the rest of your business? It doesn’t help to have operational IT in another city if your only factory is under six feet of water.

DR services are designed to protect enterprise application architectures that are centered on VMs with persistent data and configuration. A lift-and-shift cloud adoption strategy leads to enterprise applications in the cloud, requiring cloud-to-cloud DR that is very similar to DRaaS from on-premises. Keep in mind, however, that cloud-native applications have different DR requirements.

GigaOm Radar for DDoS Protection

Published

on

With ransomware getting all the news coverage when it comes to internet threats, it is easy to lose sight of distributed denial of service (DDoS) attacks even as these attacks become more frequent and aggressive. In fact, the two threats have recently been combined in a DDoS ransom attack, in which a company is hit with a DDoS and then a ransom demanded in exchange for not launching a larger DDoS. Clearly, a solid mechanism for thwarting such attacks is needed, and that is exactly what a good DDoS protection product will include. This will allow users, both staff and customers, to access their applications with no indication that a DDoS attack is underway. To achieve this, the DDoS protection product needs to know about your applications and, most importantly, have the capability to absorb the massive bandwidth generated by botnet attacks.

All the DDoS protection vendors we evaluated have a cloud-service element in their products. The scale-out nature of cloud platforms is the right response to the scale-out nature of DDoS attacks using botnets, thousands of compromised computers, and/or embedded devices. A DDoS protection network that is larger, faster, and more distributed will defend better against larger DDoS attacks.

Two public cloud platforms we review have their own DDoS protection, both providing it for applications running on their public cloud and offering only cloud-based protection. We also look at two content delivery networks (CDNs) that offer only cloud-based protection but also have a large network of locations for distributed protection. Many of the other vendors offer both on-premises and cloud-based services that are integrated to provide unified protection against the various attack vectors that target the network and application layers.

Some of the vendors have been protecting applications since the early days of the commercial internet. These vendors tend to have products with strong on-premises protection and integration with a web application firewall or application delivery capabilities. These companies may not have developed their cloud-based protections as fully as the born-in-the-cloud DDoS vendors.

In the end, you need a DDoS protection platform equal to the DDoS threat that faces your business, keeping in mind that such threats are on the rise.
