CTOnews.com, June 18 (Xinhua)-- Downdetector.com, a service outage tracking site, said on June 5 this year that Microsoft Microsoft 365had a sudden massive outage of its product suite, including Word and Excel, and that at least 15000 users were unable to use services such as email. The accident lasted more than two hours, and there was another brief incident the next morning.

In response, Microsoft said that the downtime that affected some of its services earlier this month was caused by cyber attacks, but fortunately no signs of customer data theft were found. Microsoft said it had launched an investigation and began tracking DDoS attacks launched by threat actor Storm-1359.

"since early June 2023, Microsoft has seen a surge in service traffic, making the service temporarily unavailable," the company wrote in a blog post.

CTOnews.com Note: DDoS attack is a distributed denial of service attack, which takes the server offline by directing a large amount of Internet traffic to the target server. Its technology is relatively simple.

This form of network attack attempts to flood the website or network resources with malicious traffic, resulting in the normal operation of the website or network resources. In a distributed denial of service (DDoS) attack, the attacker sends out a large amount of Internet traffic that is actually not needed, exhausting the resources of the target and preventing the normal traffic from reaching the intended destination.
