Microsoft Confirms Layer 7 DDoS Attacks by Anonymous Sudan

Microsoft representatives have officially confirmed that the recent outages in the Azure, Outlook and OneDrive portals were caused by Layer 7 DDoS attacks. The company attributed these attacks to the Storm-1359 group, which calls itself Anonymous Sudan.

Service Disruptions

Service disruptions were observed in early June 2023. According to Bleeping Computer, Outlook.com was attacked on June 7, OneDrive on June 8, and the Microsoft Azure portal on June 9. At the time, Microsoft did not officially report DDoS attacks, but it was understandable that they were the cause, as the company noted that in some cases, load balancing processes were applied to mitigate the problem.

Anonymous Sudan Claims Responsibility

The Anonymous Sudan group claimed responsibility for the attacks, claiming that Microsoft was DDoSing to protest US interference in Sudan’s internal affairs.
“We can attack any American company we want. Americans, don’t blame us, blame your government for plans to interfere in the internal affairs of Sudan. We will continue to target large US companies, government and infrastructure,” the hackers wrote.
As the Microsoft Security Response Center has now officially confirmed, the service outages were indeed caused by Layer 7 DDoS attacks, and the hack group tracked by the company under the identifier Storm-1359 is responsible for this.
“Since the beginning of June 2023, Microsoft has been detecting traffic spikes for some services that temporarily impacted their availability. These attacks likely relied on access to a number of VPSs combined with rented cloud infrastructure, open proxies, and DDoS tools,” the report says.
The researchers add that Anonymous Sudan uses three types of Layer 7 DDoS in its attacks: HTTP(S) flood, Cache bypass and Slowloris.

Background of Anonymous Sudan

Although Microsoft tracks this group as Storm-1359, it has already been said above that the group is better known as Anonymous Sudan. The group appeared in January 2023, stating that it would such as any country that opposes Sudan.
For the past six months, the group has been targeting organizations and government agencies around the world, staging DDoS attacks, as well as hacks and data leaks. Beginning in May 2023, the hack group attacked large organizations demanding a ransom to stop DDoS attacks. Initially, such attacks targeted Scandinavian Airlines (SAS), and then the hackers switched to the websites of American companies such as Tinder, Lyft, and medical institutions throughout the United States.
When Anonymous Sudan turned their attention to Microsoft and launched DDoS attacks on Outlook, Azure and OneDrive, they demanded $1,000,000 to stop the attacks.
“You failed to repel an attack that lasted several hours, so how about paying us $1,000,000 and we will train your cybersecurity specialists to repel attacks and stop the attack from our side? A million US dollars is nothing for a company like yours,” the attackers wrote.
At the same time, some IS researchers believe that the group is acting under a false flag and may in fact be a state-sponsored actor. However, there is no evidence to support this theory.

Microsoft’s Response

Microsoft has not commented on the demands of Anonymous Sudan, but the company has taken steps to protect its services from DDoS attacks. Microsoft has implemented a number of measures to protect its services from DDoS attacks, including the use of advanced machine learning algorithms to detect and block malicious traffic.
