Microsoft Azure customer hit by 2.4 Tbps DDoS attack

Microsoft has confirmed to mitigate a massive DDoS attack originated from a botnet comprising 70,000 compromised IoT devices.

Microsoft reported that an unnamed customer of its Azure cloud platform was targeted with a 2.4 Tbps DDoS attack in the last week of August, which the company mitigated.

This DDoS attack was around 140% higher than the attack recorded in 2020 as it surpassed the 2.3 Tbps attack detected and stopped by Amazon Web Services (AWS) back in Feb 2020.
