Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the Cloudflare breach identified under incident ID CLO1769705152.

The analysis begins with a detailed overview of Cloudflare's information like the linkedin page: https://www.linkedin.com/company/cloudflare, the number of followers: 1140726, the industry type: Computer and Network Security and the number of employees: 6899 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 465 and after the incident was 453 with a difference of -12 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Cloudflare and their customers.

On 19 December 2024, Cloudflare disclosed DDoS issues under the banner "Record-Breaking DDoS Attack by Aisuru/Kimwolf Botnet Peaks at 31.4 Tbps".

On December 19, Cloudflare mitigated a historic distributed denial-of-service (DDoS) attack launched by the Aisuru (also known as Kimwolf) botnet, reaching an unprecedented 31.4 Tbps and 200 million requests per second (rps).

The disruption is felt across the environment, affecting Telecommunications providers, IT organizations and Cloudflare infrastructure.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Automated systems mitigated attacks without triggering internal alerts.

Overall, the incident is a reminder of why proactive monitoring and strong governance matter.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

MITRE ATT&CK® Correlation Analysis

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with lower confidence (40%), supported by evidence indicating compromised IoT devices and routers, primarily Android TVs. Under the Resource Development tactic, the analysis identified Botnet (T1583.003) with high confidence (90%), with evidence including aisuru/Kimwolf Botnet, 500,000 IP addresses, and 90% of attacks peaked between 1-5 Tbps and Compromise Infrastructure: Botnet (T1584.001) with high confidence (90%), supported by evidence indicating compromised IoT devices and routers, primarily Android TVs. Under the Impact tactic, the analysis identified Network Denial of Service (T1498) with high confidence (100%), with evidence including 31.4 Tbps DDoS attack, 200 million requests per second (rps), and hTTP and Layer 4 DDoS attacks and Direct Network Flood (T1498.001) with high confidence (90%), with evidence including hyper-volumetric HTTP and Layer 4 DDoS attacks, and attacks peaked between 1-5 Tbps. Under the Command and Control tactic, the analysis identified Proxy (T1090) with moderate to high confidence (80%), with evidence including botnet originating from 500,000 IP addresses, and compromised IoT devices and routers. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
