The article reports on the largest recorded distributed denial-of-service (DDoS) attack, which peaked at 5.6 terabits per second and was executed by a Mirai botnet comprising 13,000 devices. The attack was directed at an East Asian ISP on October 29, yet the automated detection and mitigation systems thwarted its impacts. Notably, hyper-volumetric DDoS attacks are on the rise, highlighted by a 175% increase in attacks surpassing 100 million packets per second. Furthermore, DDoS incidents are shortening, making response and analysis increasingly challenging, often coinciding with peak user activity. Extortion is also emerging as a common tactic post-attack.
The largest DDoS attack recorded peaked at 5.6 Tbps, exerted significant pressure on East Asian internet infrastructure, yet was successfully mitigated by autonomous systems.
Hyper-volumetric DDoS attacks are becoming increasingly frequent, surpassing the 1 Tbps mark in late 2024, indicating a troubling trend in attack sophistication.
Most modern DDoS attacks are significantly shorter in duration, with a staggering 91% of network-layer attacks concluding in under 10 minutes, complicating detection efforts.
Many attacks follow a pattern of extortion, where attackers leverage the threat of DDoS to demand ransoms, further exacerbating the security landscape.
