Microsoft revealed that it thwarted one of the largest cyber attacks in its history, involving 70,000 computerOver the past month, the tech giant said it was able to fight a massive distributed service (DDoS) breach.
According to the British newspaper, “Daily Mail”, it was 140 percent higher than the highest bandwidth size of the attack recorded by Microsoft in 2020, as the attack targeted one of its customers in Europe, via cloud computing service.
DDoS attacks work by flooding the victim’s system with “internet traffic” in an attempt to overload it and force it offline, and are typically carried out through a network of devices that have been compromised with malware or malware to control them remotely.
This latest attack throttled its system with 2.4 terabytes of data per second (Tbps), Microsoft said, significantly larger than the 1Tbps attack late last summer.
It lasted more than 10 minutes, with short bursts of traffic peaking at 2.4 terabytes per second, 0.55 terabytes per second, and finally 1.7 terabytes per second, and to put the numbers in context, one terabyte is 1,000 gigabytes, which is The equivalent of hundreds of 4K movies.
It was very difficult to flood the system with that amount of data every second, but Azure was able to stay online all the time due to its ability to absorb tens of terabytes of DDoS attacks.
“Attacks of this scale demonstrate the ability of bad actors to wreak havoc by flooding targets with massive traffic volumes in an attempt to throttle network capacity,” said Amir Dahan, Azure Networking Director of Programs.
“The attack traffic originated from about 70,000 sources and from multiple countries in the Asia-Pacific region, such as Malaysia, Vietnam, Taiwan, Japan and China, as well as from the United States,” Dahan added.
Microsoft did not name the Azure client that was targeted, but said it was able to prevent the attack on them, and these hacks can also be used as a cover for secondary attacks that try to spread malware and infiltrate the company’s systems.
Microsoft said it also detected a 25% increase in the number of DDoS attacks since the last quarter of 2020, despite being one of the biggest attacks on Microsoft ever, but it wasn’t the biggest DDoS attack ever. 2.54 terabytes per second that was part of a six-month campaign using multiple methods of attack.
