Sample investigation topics

Alert information

  • We saw a new type of alert for a living-off-the-land binary. We can provide the alert ID. Can you tell us more about this alert and how we can investigate it further?
  • We’ve observed two similar attacks, which both 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?
  • We received an odd alert today about an abnormal number of failed logins from a high profile user’s device. We can’t find any further evidence for these attempts. How can Microsoft 365 Defender see these attempts? What type of logins are being monitored?
  • Can you give more context or insight about the alert, “Suspicious behavior by a system utility was observed”?
  • I observed an alert titled “Creation of forwarding/redirect rule”. I believe the activity is benign. Can you tell me why I received an alert?

Possible machine compromise

  • Can you help explain why we see a message or alert for “Unknown process observed” on many devices in our organization? 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, dating from last week? It’s behaving similarly as a previous malware detection on the same system six months ago.

Threat intelligence details

  • We detected a phishing email that delivered a malicious Word document to a user. The document caused a series of suspicious events, which triggered multiple alerts for a particular malware family. Do you have any information on this malware? If yes, can you send us a link?
  • We recently saw a blog post about a threat that is targeting our industry. Can you help us understand what protection Microsoft 365 Defender provides against this threat actor?
  • We recently observed a phishing campaign conducted against our organization. Can you tell us if this was targeted specifically to our company or vertical?

Microsoft Threat Experts’ alert communications

  • Can your incident response team help us address the targeted attack notification that we got?
  • We received this targeted attack notification from Microsoft Threat Experts. We don’t have our own incident response team. What can we do now, and how can we contain the incident?
  • We 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?

 Note

Microsoft Threat Experts is a managed threat hunting service and not an incident response service. However, you can engage with your own incident response team to address issues that require an incident response. If you don’t have your own incident response team and would like Microsoft’s help, you can engage with the CSS Cybersecurity Incident Response Team (CIRT). They can open a ticket to help address your inquiry.

Scenario

Receive a progress report about your managed hunting inquiry

The response from Microsoft Threat Experts will vary according to your inquiry. You’ll generally receive one of the following responses:

  • More information is needed to continue with the investigation
  • A file or several file samples are needed to determine the technical context
  • Investigation requires more time
  • Initial information was enough to conclude the investigation

If an expert requests more information or file samples, it’s crucial to respond quickly to keep the investigation moving.
