Preserve the email chain, determine whether the recipient executed an attachment, and inspect affected endpoints for suspicious scheduled tasks. If malicious execution is confirmed, contain the device through your incident-response process and investigate remaining access.

For an October 8, 2026 review, Microsoft's September 29 report provides a fresh hunting lead: Star Blizzard uses RedFlick scheduled tasks to deliver the CosmicPulse backdoor. Reported targets include Ukrainian institutions and organizations supporting Ukraine.

Microsoft describes initial emails often arriving without attachments, followed by password-protected archives after a recipient responds. Some campaigns use accounts on compromised websites.

Suggested triage record: recipient, sender address, message identifiers, attachment hash, delivery time, and reported user actions. Verify unexpected invitations through an established contact channel; search for matching messages across other recipients.

Microsoft observed installers creating multiple scheduled tasks with names resembling legitimate network components. Its report supplies hunting queries and indicators for investigation. [Technical findings and hunting guidance](https://www.microsoft.com/en-us/security/blog/2026/09/29/star-blizzard-refines-phishing-and-malware-delivery-with-the-redflick-technique/).

For each suspicious task, capture its definition, creation time, execution account, action, and referenced files before removal. Correlate those details with installer activity, parent processes, and outbound connections; a task name alone is insufficient evidence.

Suggested response sequence: isolate affected endpoints using approved controls, preserve available evidence, then remove malicious persistence through the incident lead's recovery plan. Search other devices for the same attachment hashes, task actions, and suspicious destinations.

Assess whether affected accounts or sessions also require recovery. Record what supports each action and verify that removed persistence does not return after the device resumes normal operation.

Give leadership separate counts for message recipients, devices with confirmed execution, and devices whose status remains unresolved. Assign an owner and next review time to each unresolved case.

Record which logs and dates were reviewed before closing the investigation. When evidence is missing, state that limitation explicitly rather than treating an empty search result as proof that no compromise occurred.
