The recent Microsoft outage affecting services like Microsoft Teams was caused by a configuration change, which was swiftly identified and reversed by Microsoft, restoring service availability. Simultaneously, a series of Distributed Denial of Service (DDoS) attacks, carried out by a group known as Storm-1359, targeted Microsoft’s cloud infrastructure. These attacks employed techniques such as HTTP(S) flood attacks, cache bypass, and Slowloris attacks to overwhelm Microsoft’s systems.

While there is no direct evidence linking the configuration error to the DDoS attacks, the concurrence of these issues highlights significant challenges in maintaining robust cybersecurity measures and service reliability. The DDoS attacks focused on disrupting services rather than breaching data, but they emphasize the evolving threats major tech companies face. This incident underscores the need for continuous improvements in cybersecurity defenses and incident response strategies to protect against both operational mishaps and malicious attacks.
