Record levels of DDoS attacks reportedly constituted a major headache for security teams in the last year.

However, the latest in a series of high-profile strikes in cyberspace might signal even more unprecedented DDoS floods in the near future.

ConsumerConnect gathered Microsoft Incorporated in a blog post Monday, October 11, 2021, said that an undisclosed European Azure cloud platform customer suffered a record-breaking 2.4 Tbps (terabytes per second) distributed denial-of-service (DDoS) attack. Thankfully, it was mitigated by Azure’s DDoS protection platform.

Amir Dahan, Senior Programme Manager at Azure Networking, however, stated the attack was carried out during the last week of August 2021, by a botnet leveraging approximately 70,000 infected devices located across Malaysia, Vietnam, Taiwan, Japan, China, and the United States, CyberNews report said.

“This is 140 percent higher than 2020’s 1 Tbps attack and higher than any network volumetric event previously detected on Azure,” said Dahan.

The Azure Networking Networking Senior Program Manager further explained that the Azure attack from August, which lasted more than 10 minutes, was carried out in three “very short-lived bursts,” with the first peaking at 2.4 Tbps, the second at 0.55 Tbps, and the third at 1.7 Tbps.

Just the tip of the approaching iceberg?

The August cyberattack was said to have come in the wake of multiple massive high-profile DDoS attacks of increasing scale and frequency.

In terms of bitrate, the previous record-breaking DDoS attack was a 2.3 Tbps strike reported by Amazon Web Services in February 2020.

In September, the Mēris botnet hit the Russian Internet giant Yandex with a massive 21.8 million RPS (requests per second) DDoS attack, which currently holds the DDoS record in terms of RPS.

Dahan again warned: “More industries are being targeted, particularly higher education, healthcare, telecoms, and public sectors.”

According to him, DDoS attacks of this size “demonstrate the ability of bad actors to wreak havoc by flooding targets with gigantic traffic volumes trying to choke network capacity.”
