Microsoft Threat Experts is the managed threat hunting service within Microsoft Defender Advanced Threat Protection (ATP) that includes two capabilities: targeted attack notifications and experts on demand.
Today, we are extremely excited to share that experts on demand is now generally available and gives customers direct access to real-life Microsoft threat analysts to help with their security investigations.
With experts on demand, Microsoft Defender ATP customers can engage directly with Microsoft security analysts to get guidance and insights needed to better understand, prevent, and respond to complex threats in their environments. This capability was shaped through partnership with multiple customers across various verticals by investigating and helping mitigate real-world attacks. From deep investigation of machines that customers had a security concern about, to threat intelligence questions related to anticipated adversaries, experts on demand extends and supports security operations teams.
The other Microsoft Threat Experts capability, targeted attack notifications, delivers alerts that are tailored to organizations and provides as much information as can be quickly delivered to bring attention to critical threats in their network, including the timeline, scope of breach, and the methods of intrusion. Together, the two capabilities make Microsoft Threat Experts a comprehensive managed threat hunting solution that provides an additional layer of expertise and optics for security operations teams.
Experts on the case
By design, the Microsoft Threat Experts service has as many use cases as there are unique organizations with unique security scenarios and requirements. One particular case showed how an alert in Microsoft Defender ATP led to informed customer response, aided by a targeted attack notification that progressed to an experts on demand inquiry, resulting in the customer fully remediating the incident and improving their security posture.
In this case, Microsoft Defender ATP endpoint protection capabilities recognized a new malicious file in a single machine within an organization. The organization’s security operations center (SOC) promptly investigated the alert and developed the suspicion it may indicate a new campaign from an advanced adversary specifically targeting them.
Microsoft Threat Experts, who are constantly hunting on behalf of this customer, had independently spotted and investigated the malicious behaviors associated with the attack. With knowledge about the adversaries behind the attack and their motivation, Microsoft Threat Experts sent the organization a bespoke targeted attack notification, which provided additional information and context, including the fact that the file was related to an app that was targeted in a documented cyberattack.
To create a fully informed path to mitigation, experts pointed to information about the scope of compromise, relevant indicators of compromise, and a timeline of observed events, which showed that the file executed on the affected machine and proceeded to drop additional files. One of these files attempted to connect to a command-and-control server, which could have given the attackers direct access to the organization’s network and sensitive data. Microsoft Threat Experts recommended full investigation of the compromised machine, as well as the rest of the network for related indicators of attack.
Based on the targeted attack notification, the organization opened an experts on demand investigation, which allowed the SOC to have a line of communication and consultation with Microsoft Threat Experts. Microsoft Threat Experts were able to immediately confirm the attacker attribution the SOC had suspected. Using Microsoft Defender ATP’s rich optics and capabilities, coupled with intelligence on the threat actor, experts on demand validated that there were no signs of second-stage malware or further compromise within the organization. Since, over time, Microsoft Threat Experts had developed an understanding of this organization’s security posture, they were able to share that the initial malware infection was the result of a weak security control: allowing users to exercise unrestricted local administrator privilege.
Experts on demand in the current cybersecurity climate
On a daily basis, organizations have to fend off the onslaught of increasingly sophisticated attacks that present unique security challenges in security: supply chain attacks, highly targeted campaigns, hands-on-keyboard attacks. With Microsoft Threat Experts, customers can work with Microsoft to augment their security operations capabilities and increase confidence in investigating and responding to security incidents.
Now that experts on demand is generally available, Microsoft Defender ATP customers have an even richer way of tapping into Microsoft’s security experts and get access to skills, experience, and intelligence necessary to face adversaries.
Experts on demand provide insights into attacks, technical guidance on next steps, and advice on risk and protection. Experts can be engaged directly from within the Windows Defender Security Center, so they are part of the existing security operations experience:
