Security News > 2024 > August > Microsoft Confirms Global Azure Outage Caused by DDoS Attack

The Azure outage had global reach, impacting a subset of customers attempting to connect to Azure App Services, Application Insights, Azure IoT Central, Azure Log Search Alerts, Azure Policy, the Azure portal itself, and a subset of Microsoft 365 and Microsoft Purview services.

Many different organisations made statements on Tuesday, notifying users that their services were disrupted as a result of the Azure DDoS attack.

"Stephen Robinson, senior threat intelligence analyst at security firm WithSecure, told TechRepublic in an emailed statement:"Modern online services are built on stacked layers of dependencies, and in a significant proportion of service stacks you will find Microsoft services.

A denial of service attack is an attack strategy where a malicious actor attempts to prevent others from accessing a web server, web application or cloud service by flooding it with service requests.

While a DoS attack is essentially of a single origin, a distributed denial of service attack uses a large number of machines on different networks to disrupt a particular service provider; this is more challenging to mitigate as the attack is being waged from multiple sources.

On July 19, tens of thousands of users in the U.S. could not access Microsoft 365 services after an Azure configuration change.
