Azure Monitor alert was triggered

Question

Why did I get a Azure Monitor alert was triggered?

Answer 1

Hello Douglas Vander Waal, What you’re describing closely aligns with a known scam pattern involving Azure alert emails.

In these cases, attackers first gain access to an Azure subscription and then deliberately configure alert rules to send notifications to external email addresses (such as yours). They subsequently trigger those alerts. While the emails are technically generated by Azure, the alert message content itself is authored by the attackers.

These emails typically include alarming language such as:

• references to a “Fraud Prevention System” or “Windows Defender,”
• warnings about large, suspicious charges,
• threats of account suspension, and
• a so‑called “Fraud Resolution” or “Support Hotline” phone number.

The objective is to pressure recipients into calling that number, where the scam continues.

Important guidance:

• Do not call any phone number mentioned in the email.
• Do not click any links included in the message.
• Simply delete the email.

It’s worth noting that these messages can appear convincing because they are sent from legitimate Microsoft email infrastructure. However, Microsoft does not include phone numbers or urgent call‑to‑action language like this in genuine Azure alert notifications.

Hello,

If you don't use Azure product and didn't set this up, then this email is phishing scam.

Scammers took advantage of Microsoft's notification delivery system, to send you a message they crafted in the Azure system, subscribed you to their Azure product when certain rule condition was met.

If the email asks for payment or gives phone number, don't fall for it. Don't call.

Answer 3

An Azure Monitor alert is triggered when the conditions defined in an alert rule are met for the monitored resource.

An alert rule in Azure Monitor combines:

1. The resources being monitored.
2. The signal or data from those resources (metrics, logs, or activity logs).
3. The condition that defines when an alert should fire.

When the incoming data (for example, a metric value, a log query result, or an activity log event) satisfies the rule’s condition, Azure Monitor creates an alert instance, sets its condition to fired, and invokes any configured action groups (such as email, SMS, webhooks, runbooks, or Logic Apps).

To see why a specific alert fired:

1. Open the Alerts page in the Azure portal.
2. Select the fired alert instance.
3. Review the Why did this alert fire? section (for metric alerts) or the alert details (for log/activity alerts) to see the signal value and the threshold/condition at the time it triggered.

If the underlying condition later clears, the alert condition changes to resolved, but the fired alert instance remains read‑only and is retained for 30 days.
