An AD breach feels like an explosion. An Entra ID breach feels like nothing—until everything starts falling apart.

Active Directory attacks are still the go-to opening act for most data breaches. But attackers have a new favorite—your cloud identity control plane, Entra ID.

Here's the difference. In AD, they kick down the door. Compromise domain controllers, escalate privileges, deploy ransomware. It's loud, destructive, impossible to miss. You know you've been hit.

In Entra ID, they pull up a chair. Change who's trusted. Tweak who's an admin. Adjust which policies apply. Entra Connect bridges your on-prem and cloud worlds, so a compromise in one environment can quietly propagate to the other, like a software update you never asked for.

You're defending two identity systems now. And the cloud side is quieter, faster, and absurdly harder to detect.

Two Fronts, Two Playbooks

An AD breach feels like an explosion. An Entra ID breach feels like nothing—until everything starts falling apart. Here’s why.

Entra Connect is the sync engine that copies users, groups, and attributes from AD to the cloud. It's supposed to make your life easier.

Instead, it can become the reinfection vector.

If attackers compromise that connector VM, they can quietly re-inject malicious objects or group memberships, even after you've painstakingly rebuilt your domain controllers.

You celebrate your clean slate. The infection syncs right back.

Recovery is a two-part problem:

1. Clean and rebuild the connector VM in complete isolation

2. Restore trust relationships and configurations in the cloud

Miss either step? You're not recovering: you're reinfecting yourself with extra steps. This is happening in real incidents right now.

How They Unstitch You

Entra ID attackers don't crash systems. They don't need to. They sit at the console and methodically pick apart your security posture:

• Delete conditional access policies: Dial down authentication requirements. Make MFA optional.
   

• Create malicious enterprise apps: Once these apps are given blanket consent or backdoor Service Principal credentials into roles like Global Reader or Application Administrator, it’s game over.
   

• Wipe diagnostic logs: If there's no evidence, did it even happen?
   

• Compromise Entra Connect: Now, threat actors can re-sync attacker artifacts after you "clean" AD.
   

• Delete break-glass accounts: How can you effectively recover if attackers have orphaned the security groups that enforce your policies?
   

Each change looks harmless. But together, they dismantle your identity fabric one relationship at a time. You can rebuild accounts. You can't rebuild the trust between them.

You're not just hacked. You're unstitched.

Why This Hurts More

Attackers love Entra ID because it buys them what they need most: time.They can stay hidden for months while you confidently tell your Board you've already recovered. But you haven't.

The result?

Downtime accumulates: Every hour your hybrid identity is down, authentication fails across cloud apps, VPNs, and SaaS tools. Your employees can't work. Your customers can't buy. 

Compliance problems compound: Lost audit trails and deleted policies mean you can't prove what security controls were in place when the auditor or insurance company shows up. Now, you’re subject to fines and coverage disputes.

Your teams burn out: Attrition is inevitable when your staff has to spend hundreds of hours manually tracing and validating configs across two platforms. That means a deluge of spreadsheets and PowerShell scripts. How many Slack threads asking "Wait, did you check the trust relationship" can your team endure?

Traditional recovery takes two to three weeks. That's not resilience. That's expensive downtime with syntax highlighting.

How to Actually Fix This

Recovery isn't enough anymore. If you can't measure it, prove it, and explain it to your Board in under five minutes, it doesn't count.

Rubrik Identity Resilience turns vague, anxiety-inducing identity risk into a measurable, governed process—the kind you can demonstrate to your Board, your auditors, and that insurance underwriter who keeps asking uncomfortable questions.

Here are some of the benefits:

Business Continuity: Rubrik cuts hybrid identity Recovery Time Objective (RTO) from 2–3 weeks of manual chaos to hours. Unified workflows rebuild AD and Entra ID in sequence, verifying each stage before re-sync. Clean recovery points eliminate scripts and tribal knowledge. Authentication, MFA, and app access restored 10× faster. And your executives stop stress-emailing you at midnight.

Risk Reduction You Can Prove: Every restored policy, object, and connector gets cryptographically validated and automation rolls back malicious policy changes—conditional access, MFA, app consents. An Immutable audit trail saves you the headache of manually searching for every toggle an attacker flipped, making regulators surprisingly pleasant to work with. You can tell your Board that you’ve surgically reversed malicious identity changes and verified clean recovery—and mean it. That's measurable assurance that holds up.

Stop Burning Out Your Team: One orchestrated workflow replaces 50+ manual scripts, a dozen Confluence pages nobody's updated since 2019, and hours of "quick sync" meetings that are never quick. Give back 20% of your IAM team's time. Let them spend it on proactive architecture instead of being the human equivalent of Ctrl+Z.

Prove ROI: Rubrik unifies AD, Entra ID, and data protection into one platform. You can finally retire those point solutions you bought three years ago that do one thing adequately. Having one integrated source of truth for recovery and compliance delivers tangible benefits: lower licensing costs, fewer vendors, and quantifiable tool rationalization.

The Bottom Line

Modern attackers don't just crash systems. They rewrite trust—quietly, persistently, often without setting off a single alert.

The only sustainable defense? Shorten your Identity recovery time. Make it simple to prove what's clean.

Rubrik does both. 

We orchestrate recovery for AD and Entra ID on one platform, eliminate redundant tools, slash operational burden, and turn hybrid identity recovery from an expensive guessing game into a governed process with numbers you can defend.

Learn how Rubrik orchestrated recovery for Entra ID can help you accelerate your RTO.

This isn't backup. It's cyber resilience for an era where your identity infrastructure is the attack surface—and it pays for itself the first time you need it.
