Fake IT Calls Target Executives in Microsoft 365 Data Theft and Extortion Attacks

Threat hunters discovered a campaign targeting Microsoft 365 and other SaaS platforms through vishing calls impersonating IT help desk staff, token theft via adversary-in-the-middle attacks, and residential proxy logins. The scheme primarily focuses on executive-level employees for data theft and extortion purposes.

Why it matters: Organizations with Microsoft 365 deployments face elevated risk from social engineering targeting executives; security teams should implement additional verification steps for credential requests and monitor for suspicious proxy-based access patterns.
