Alert validation in Azure Security Center

This document helps you learn how to verify if your system is properly configured for Azure Security Center alerts.

What are security alerts?

Alerts are the notifications that Security Center generates when it detects threats on your resources. It prioritizes and lists the alerts along with the information needed to quickly investigate the problem. Security Center also provides recommendations for how you can remediate an attack. For more information, see Security alerts in Security Center and Managing and responding to security alerts

Generate sample Azure Defender alerts

If you’re using the new, preview alerts experience as described in Manage and respond to security alerts in Azure Security Center, you can create sample alerts in a few clicks from the security alerts page in the Azure portal.

Use sample alerts to:

• evaluate the value and capabilities of Azure Defender
• validate any configurations you’ve made for your security alerts (such as SIEM integrations, workflow automation, and email notifications)

To create sample alerts:

As a user with the role Security admin or Subscription Contributor, from the toolbar on the alerts page, select Create sample alerts.

Select the subscription.

Select the relevant Azure Defender plan/s for which you want to see alerts.

Select Create sample alerts.

A notification appears letting you know that the sample alerts are being created:

After a few minutes, the alerts appear in the security alerts page. They’ll also appear anywhere else that you’ve configured to receive your Azure Security Center security alerts (connected SIEMs, email notifications, and so on).

The alerts are for simulated resources.

Simulate alerts on your Azure VMs (Windows)

After Security Center agent is installed on your computer, follow these steps from the computer where you want to be the attacked resource of the alert:

1. Copy an executable (for example calc.exe) to the computer’s desktop, or other directory of your convenience, and rename it as ASC_AlertTest_662jfi039N.exe.
2. Open the command prompt and execute this file with an argument (just a fake argument name), such as: ASC_AlertTest_662jfi039N.exe -foo
3. Wait 5 to 10 minutes and open Security Center Alerts. An alert should appear.

When reviewing this test alert for Windows, make sure the field Arguments Auditing Enabled is true. If it is false, then you need to enable command-line arguments auditing. To enable it, use the following command:

reg add «HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\Audit» /f /v «ProcessCreationIncludeCmdLine_Enabled»

Simulate alerts on your Azure VMs (Linux)

After Security Center agent is installed on your computer, follow these steps from the computer where you want to be the attacked resource of the alert:

Copy an executable to a convenient location and rename it to ./asc_alerttest_662jfi039n, for example:

cp /bin/echo ./asc_alerttest_662jfi039n

Open the command prompt and execute this file:

./asc_alerttest_662jfi039n testing eicar pipe

Wait 5 to 10 minutes and open Security Center Alerts. An alert should appear.

Simulate alerts on Kubernetes

If you’ve integrated Azure Kubernetes Service with Security Center, you can test that your alerts are working with the following kubectl command:

kubectl get pods —namespace=asc-alerttest-662jfi039n

For more information about defending your Kubernetes nodes and clusters, see Introduction to Azure Defender for Kubernetes

Windows Security Alert removal instructions

What is Windows Security Alert?

«Windows Security Alert» is a fake error message displayed by a malicious website. Users often visit this website inadvertently — they are redirected by potentially unwanted adware-type programs (PUPs). These apps usually infiltrate systems without consent. As well as causing unwanted redirects, this type of adware collects various data relating to Internet browsing activity and delivers intrusive online advertisements.

The «Windows Security Alert» error message states that the computer has been infected and that private details (email logins, banking details, etc.) are at risk. It is emphasised that the ‘problem’ must be solved immediately by calling the toll-free telephone number («1-844-826-1198«) provided. Victims then supposedly receive help in removing the malware. Be aware, however, that «Windows Security Alert» is fake. None of the listed viruses exist. Cyber criminals merely attempt to scare and trick victims into calling and paying for services that are not needed. Therefore, you should ignore this pop-up and never call the number. This app gathers IP addresses, search queries, websites visited, pages viewed, and other similar data that might be personally identifiable and shared with third parties (potentially, cyber criminals) who generate revenue by misusing personal details. Therefore, the presence of an information-tracking app on your system can lead to serious privacy issues or even identity theft. In addition, this adware delivers intrusive online advertisements. To achieve this, developers employ a ‘virtual layer’ — a tool that enables placement of third party graphical content on any site. These ads often conceal content of visited websites, thereby significantly diminishing the web browsing experience. In addition, they often redirect to malicious websites — even accidental clicks can result in high-risk adware or malware infections. Potentially unwanted programs must be uninstalled immediately.

Threat Summary:

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.

There are dozens of fake errors similar to «Windows Security Alert» including Microsoft Office Activation Wizard, Your PC Ran Into A Problem, and Your Computer May Be At Risk — these are just some examples from many. All claim that the computer is infected, missing system files, or damaged in other similar ways. These claims are false. As mentioned above, fake errors such as «Windows Security Alert» are designed only to generate revenue by tricking victims into paying. All adware-type apps are also very similar. By offering various ‘useful features’, PUPs attempt to give the impression of legitimacy, however, they are designed to collect personal data, deliver intrusive online advertisements and, in this case, cause unwanted redirects. PUPs are useless for regular users.

Another variant of this scam «Microsoft Security Alert«, uses a number of +1-844-257-9402:

How did adware install on my computer?

Adware-type applications are often distributed via a deceptive marketing method called «bundling» (stealth installation of PUPs with regular software). Developers know that most users rush the download/installation processes and skip most steps. Therefore, bundled programs are hidden within the «Custom/Advanced» settings. Skipping this section often leads to inadvertent installation of rogue applications.

How to avoid installation of potentially unwanted applications?

Installation of PUPs can be prevented by taking two simple steps. Firstly, never rush when downloading and installing software. Select the «Custom/Advanced» settings and carefully analyze each step. Secondly, decline offers to download/install additional applications and cancel those already included. The key to computer safety is caution.
