In our own security products, we continue to invest heavily in capabilities that take advantage of the cloud and artificial intelligence AI to empower your team and let them focus on the most important tasks to protect against threats and keep information secure. We made several key strides in security to strengthen protection for our customers:.
IoT deployments can help organizations cut costs with predictive maintenance or to create new revenue streams from connected products. Unfortunately, the security pro talent shortage makes it difficult to successfully plan the IoT security controls necessary. We worked with the Industrial Internet Consortium to produce a new IoT Security Maturity Model that provides clear industry best practices for evaluating your IoT risk profile and planning the remediation you need.
The new guardian modules built on Azure Sphere bring the security of Azure Sphere to brownfield IoT devices, allowing your business groups to complete IoT deployments without increasing risk for your organization. Its role is simply to empower you—the defenders. You can learn more about Microsoft security at booth I know you may find some of the trends, such as the increase in cryptocurrency mining and supply chain activity, worrisome. We analyzed the 6.
We gathered insights from thousands of security researchers based around the world, and we learned lessons from real-world experiences, like the Ursnif campaign and the Dofoil coin-miner outbreak. There is a lot going on, but the SIR team distilled the data down into four key trends:. The decline of ransomware attacks that we saw in the data is a great example of how the security community is pushing bad actors to adjust.
Just last year, we highlighted the large threat that ransomware played in the data, so this decline is notable. We believe that attackers have shifted from this highly visible method to more stealth attacks because users have gotten smarter about how they respond. The decline in ransomware is good news; however, on the flip side we are seeing cryptocurrency mining to be prevalent.
This is one of the methods that attackers have deployed in lieu of ransomware. The SIR report provides a great overview of how cryptocurrency works and other factors driving this trend. Software supply chain attacks are another trend that Microsoft has been tracking for several years. One supply chain tactic used by attackers is to incorporate a compromised component into a legitimate application or update package, which then is distributed to the users via the software.

These attacks can be very difficult to detect because they take advantage of the trust that users have in their software vendors. The report includes several examples, including the Dofoil campaign, which illustrates how wide-reaching these types of attacks are and what we are doing to prevent and respond to them. The good news: much like ransomware, bad actors have shifted tactics in response to the more sophisticated tools and techniques that have been deployed to protect users. We uncovered a lot of details about these new phishing methods that we hope you find useful in your fight to defend against them.
When I was a practitioner, I sought out reports like these to help me better understand attacker techniques and plan my defenses accordingly.

Attack surface reduction is a technique to remove or constrain exploitable behaviors in your systems. In this blog, we discuss the two attack surface reduction rules introduced in the most recent release of Windows and cover suggested deployment methods and best practices. Software applications may use known, insecure methods, or methods later identified as useful for malware exploits. For example, macros are an old and powerful tool for task automation. However, macros can spawn child processes, invoke the Windows API, and perform other tasks which render them exploitable by malware.
Windows Defender Advanced Threat Protection Windows Defender ATP enables you to take advantage of attack surface reduction rules that allow you to control exploitable threat vectors in a simple and customizable manner. In previous releases of Windows we launched rules that let customers disallow remote process creation through WMI or PSExec and block Office applications from creating executable content. Other rules include the ability to disable scripts from creating executable content or blocking file executions unless age and prevalence criteria are met.
The latest attack surface reduction rules in Windows Defender ATP in latest re based on system and application vulnerabilities uncovered by Microsoft and other security companies. Below we describe that these rules do. More importantly, we outline recommendations for deploying these rules in enterprise environments.
The Block Office Communication Applications from Creating Child Processes rule protects against attacks that attempt to abuse the Outlook email client. In this case, this attack surface reduction rule disables the creation of another process from Outlook — this means that DDE still works and data can be exchanged by two running applications, but new processes cannot be created.
Many line-of-business applications rely on this capability. If, for example, DDE is not used in your organization, or if you want to restrict the capability of DDE to already running processes, this can be configured by using the AllowDDE registry key for Office. By limiting child processes that can be launched by Outlook to only processes with well-defined functionality, this attack surface reduction rule confines a potential exploit or a social engineering threat from further infecting or compromising the system.
While there may be legitimate business reasons for a business PDF file to create a child process through scripting, this is a behavior that should be discouraged as it is prone to misuse. Our data indicates few legitimate applications utilize this technique. Attack surface reduction rules close frequently used and exploitable behaviors in the operating system and in apps. However, legitimate line-of-business and commercial applications have been written utilizing these same behaviors.

To enable non-malicious applications critical to your business, exclusions can be used if they are flagged as violating an attack surface reduction rule. Core Microsoft components, such as operating system files or Office applications, reside in a global exclusion list maintained as part of Defender. These do not need exclusions. Exclusions, when applied, are honored by other Windows Defender ATP exploit mitigation features including Controlled folder access and Network protection , in addition to attack surface reduction rules. This simplifies exclusion management and standardizes application behavior.
Attack surface reduction rules have three settings: off, audit, and block. Our recommended practice to deploy attack surface reduction rules is to first implement the rule in audit mode.
Audit mode will identify exploitable behavior use but will not block the behavior. With audit, if you have a line of business application utilizing a behavior that is exploitable, the invoking application can be identified, and an exclusion added. When audit telemetry reveals that line-of-business applications are no longer being impacted by the attack surface reduction rule, the attack surface reduction rule setting can be switched to block.
This will protect against malware exploitation of the behavior.
Rings are groups of machines radiating outward like non-overlapping tree rings. When the inner ring is successfully deployed with required exclusions, the next ring can be deployed. One of the ways you can create a ring process is by creating specific groups of users or devices in Intune or with a Group Policy management tool.
Once a rule is deployed in block mode, it is important to monitor corresponding event telemetry. This data contains important information. For example, an application update may now require an exclusion or multiple alerts from a user clicking on email executable attachments can indicate additional training is required. Attack surface reduction rule events may be from a single, random malware breach, or your organization may be the object of a new, persistent attack attempting to utilize a vector covered by attack surface reduction rules suddenly producing a large increase in related attack surface reduction-rule block events.
Minimizing your attack surface can yield large paybacks in decreased threat vulnerability and in allowing the security operations team to focus on other threat vectors. As with all security features, enable attack surface reduction rules in a methodical, controlled manner that allows legitimate business applications to be excluded from analysis.
