Sample investigation topics that you can consult with Microsoft Threat Experts

Alert information

  • We see a new type of alert for a living-off-the-land binary: [AlertID]. Can you tell us something more about this alert and how we can investigate further?
  • We’ve observed two similar attacks, which try to execute malicious PowerShell scripts but generate different alerts. One is "Suspicious Powershell command line" and the other is "A malicious file was detected based on indication provided by O365". What is the difference?
  • I receive an odd alert today for abnormal number of failed logins from a high profile user’s device. I cannot find any further evidence around these sign-in attempts. How can Microsoft Defender ATP see these attempts? What type of sign-ins are being monitored?
  • Can you give more context or insights about this alert: “Suspicious behavior by a system utility was observed”.

Possible machine compromise

  • Can you help answer why we see “Unknown process observed?” This message or alert is seen frequently on many devices. We appreciate any input to clarify whether this message or alert is related to malicious activity.
  • Can you help validate a possible compromise on the following system on [date] with similar behaviors as the previous [malware name] malware detection on the same system in [month]?

Threat intelligence details

  • This morning, we detected a phishing email that delivered a malicious Word document to a user. This caused a series of suspicious events, which triggered multiple Microsoft Defender alerts for [malware name] malware. Do you have any information on this malware? If yes, can you send me a link?

Microsoft Threat Experts’ alert communications

  • Can your incident response team help us address the targeted attack notification that we got?

  • I received a targeted attack notification from Microsoft Threat Experts. What data can you provide to us that we can pass on to our incident response team?


    Microsoft Threat Experts is a managed cybersecurity hunting service and not an incident response service. However, the experts can seamlessly transition the investigation to Microsoft Cybersecurity Solutions Group (CSG)'s Detection and Response Team (DART) services, when necessary. You can also opt to engage with your own incident response team to address issues that requires an incident response.
