Imagine opening your inbox and seeing an email that appears to come from… you. No, it’s not a typo. It’s the latest tactic cybercriminals are using to trick employees and infiltrate organizations.
At Ascend Technologies, our Security Operations Center (SOC) recently spotted a wave of phishing emails hitting Microsoft 365 users. What made them especially deceptive? The sender looked identical to the recipient.
This real-world attack highlights why modern security requires more than just off-the-shelf protections.
The Threat: A New Spin on Phishing
A new phishing method is making its way through Microsoft environments by taking advantage of how some email systems are configured. These emails show up in inboxes looking like they were sent from the user’s own address. Naturally, this makes them more believable—and dangerous.
Clicking the link or attachment in one of these emails can expose credentials, allow unauthorized access, or even open the door to ransomware.
Why This Threat Is So Effective
Cybercriminals are smart. They know that people are more likely to trust an email that looks like it’s from someone they know—or themselves.
These phishing emails bypass traditional filters by disguising the sender and taking advantage of systems that haven’t been fully secured or monitored. Unfortunately, many businesses don’t realize their Microsoft environments need extra attention beyond default settings.
Active Defense Is Essential for Modern Microsoft Environments
Cybersecurity is no longer just about having the right tools—it’s about building an active, adaptive strategy that evolves with the threat landscape. For organizations operating in Microsoft 365, that means going beyond default settings and taking a proactive approach to security.
At Ascend, we’ve developed a managed Microsoft security suite called Ascend Defend that illustrates what this kind of strategy looks like in action. It’s designed to address the unique challenges businesses face when securing Microsoft environments—particularly when threats like the recent self-spoofed phishing attacks emerge.
Here are a few core components of an effective Microsoft 365 security approach:
-
24/7 Monitoring by a Dedicated Security Team
Around-the-clock visibility is critical. Continuous monitoring allows for real-time detection of suspicious activity—helping stop threats before they escalate. -
Proactive Configuration and Hardening
Many Microsoft environments are vulnerable due to overlooked settings or legacy configurations. Regular reviews and proactive adjustments can close those gaps and reduce exposure. -
Behavioral and Context-Aware Threat Detection
Traditional filters alone aren’t enough. Modern detection strategies include behavioral analysis and tailored rules that can identify more subtle or evolving attacks, like phishing emails that appear to come from the user themselves. -
Coordinated and Timely Response
Detection without action isn’t protection. Effective security includes clear processes and the right expertise to respond quickly when something’s detected.
Without a dedicated team to manage these areas, organizations risk leaving blind spots in their Microsoft security posture—regardless of licensing level.
A Real-World Response, Without the Disruption
Thanks to early detection and the layered protections in place through Ascend Defend, our clients experienced zero operational impact from this phishing campaign. The exploit was contained, the threat was neutralized, and end users were shielded—without disruption or confusion.
