A recent record-setting DDoS attack by the AISURU/Kimwolf botnet has highlighted the growing threat landscape in the world of cybersecurity. With DDoS attacks surging by 121% in 2025, reaching an average of 5,376 attacks automatically mitigated every hour, it is imperative that businesses and individuals take a proactive approach to securing themselves against these threats.
A record-setting DDoS botnet known as AISURU/Kimwolf was detected by Cloudflare, peaking at 31.4 Terabits per second. Cloudflare mitigated a staggering 34.4 million network-layer DDoS attacks in 2025, more than doubling from 2024. AISURU/Kimwolf ensnared over 2 million Android devices into its botnet, mostly through compromised off-brand Android TVs and residential proxy networks. The origins of AISURU/Kimwolf can be traced back to a series of DDoS campaigns codenamed The Night Before Christmas in December 2025. DDoS attacks are rapidly growing in sophistication and size, presenting a significant challenge for organizations to keep pace.
A recent report by Cloudflare, a leading web infrastructure company, has shed light on the rapidly evolving threat landscape in the world of cybersecurity. The report highlights the emergence of a record-setting distributed denial-of-service (DDoS) botnet known as AISURU/Kimwolf, which launched a massive attack that peaked at an astonishing 31.4 Terabits per second (Tbps) and lasted for only 35 seconds.
This behemoth of a botnet has been part of a growing number of hyper-volumetric HTTP DDoS attacks mounted by the group in the fourth quarter of 2025, with Cloudflare detecting this activity automatically and mitigating it to prevent any potential harm. According to Cloudflare's Omer Yoachimik and Jorge Pacheco, DDoS attacks surged by 121% in 2025, reaching an average of 5,376 attacks automatically mitigated every hour, with the total number of DDoS attacks more than doubling to an incredible 47.1 million.
The company noted that it mitigated a staggering 34.4 million network-layer DDoS attacks in 2025, compared to 11.4 million in 2024, with Q4 2025 seeing a significant spike in these types of attacks accounting for 78% of all DDoS attacks. Furthermore, the number of hyper-volumetric attacks increased by 40% compared to the previous quarter, witnessing a jump from 1,304 to 1,824.
AISURU/Kimwolf has ensnared more than 2 million Android devices into its botnet, most of which are compromised off-brand Android TVs, often by tunneling through residential proxy networks like IPIDEA. The company partnered with Cloudflare to disrupt the proxy network and initiate legal action to take down dozens of domains used to control devices and proxy traffic through them.
The origins of AISURU/Kimwolf can be traced back to a series of DDoS campaigns codenamed The Night Before Christmas that commenced on December 19, 2025. Per Cloudflare, the average size of these hyper-volumetric DDoS attacks during the campaign was 3 billion packets per second (Bpps), 4 Tbps, and 54 requests per second (Mrps), with the maximum rates touching 9 Bpps, 24 Tbps, and 205 Mrps.
The sheer scale and sophistication of AISURU/Kimwolf's attack should serve as a stark reminder of the ever-evolving threat landscape in the world of cybersecurity. As Cloudflare noted, DDoS attacks are rapidly growing in sophistication and size, surpassing what was previously imaginable, presenting a significant challenge for many organizations to keep pace.
"The evolving threat landscape presents a significant challenge for many organizations to keep pace," said Omer Yoachimik and Jorge Pacheco. "Organizations currently relying on on-premise mitigation appliances or on-demand scrubbing centers may benefit from re-evaluating their defense strategy."
In light of this report, it is imperative that businesses and individuals take a proactive approach to securing themselves against the ever-rising tide of cyber threats. As the threat landscape continues to evolve at an unprecedented pace, it is essential to stay vigilant and adapt our defenses accordingly.
