The Growing Risk of Social Engineering in the Cloud

Social engineering is one of the most effective ways attackers bypass technical defenses — especially when targeting cloud-hosted workloads, identities, and data. These attacks exploit human behavior to gain unauthorized access or exfiltrate sensitive information.

Types of Social Engineering Attacks in Cloud Environments

Attackers may target IT admins or DevOps teams with phishing emails impersonating internal support or security tools. They may also craft MFA fatigue attacks, abuse OAuth token permissions, or share malicious links through trusted cloud collaboration tools.

Microsoft Defender for Cloud: Risk Detection and Recommendations

Defender for Cloud proactively identifies suspicious behaviors, such as privileged accounts without MFA, excessive permissions, or anomalous sign-ins. It recommends actionable mitigations, like enforcing Conditional Access or role cleanups.

Microsoft Sentinel: Phishing and Impersonation Detection

Sentinel ingests signals from Microsoft Defender for Office 365, Exchange Online, and third-party email security tools. It identifies social engineering patterns, such as credential harvesting attempts or reply-chain impersonations, and connects them to broader threat campaigns.

Microsoft Purview: Data Access and Loss Prevention

Purview can detect if socially engineered users accessed or shared sensitive data — including financial records, intellectual property, or personal health information. It enables organizations to trace data movement and apply governance policies like encryption and access expiration.

Copilot in Azure: Accelerated Investigation and Threat Response

With Copilot, security teams can ask natural language queries such as “Has any user downloaded files after clicking a phishing link?” or “Which accounts accessed sensitive data from unknown IPs?” Copilot turns these into real-time threat-hunting queries and recommends mitigation steps.

Real-World Scenario

A global healthcare provider received a phishing email that appeared to be from their internal billing system. One employee clicked a link and entered credentials. Defender for Cloud flagged suspicious login activity, Sentinel identified lateral movement, Purview confirmed that no sensitive patient records were accessed, and Copilot generated an email to IT recommending user offboarding and credential resets.

Conclusion

Social engineering attacks can bypass even the strongest technical defenses if users aren’t protected by layered tools and insights. SecureStack™ — combining Microsoft Defender for Cloud, Sentinel, Purview, and Copilot in Azure — provides a proactive and automated defense posture. It helps detect phishing, enforce secure configurations, limit data exposure, and speed up incident response.
