Cloudflare has successfully mitigated a record-breaking DDoS attack, peaking at 3.8 Tbps, which is linked to the ASUS router authentication bypass vulnerability (CVE-2024-3080). The attack highlights the need for organizations to prioritize network security and adhere to best practices in preventing similar breaches.
The recent DDoS attack was record-breaking, peaking at 3.8 terabits per second (Tbps) and 2.14 billion packets per second (pps). The attack exploited the ASUS router authentication bypass vulnerability (CVE-2024-3080), allowing unauthenticated remote attackers to log in to these devices. The attackers used UDP traffic originating from compromised devices located across various countries, including Vietnam, Russia, Brazil, Spain, and the United States. Cloudflare's defense mechanisms played a crucial role in mitigating the attack, successfully defending against over 100 hyper-volumetric DDoS attacks during September. The ASUS router authentication bypass vulnerability is a critical flaw that poses a significant threat to network infrastructure and security, emphasizing the need for organizations to maintain up-to-date security patches and adhere to best practices regarding network security.
The cybersecurity landscape has witnessed a significant escalation in recent times, particularly with regards to Distributed Denial-of-Service (DDoS) attacks. A most recent example that has garnered considerable attention is the record-breaking DDoS attack carried out by an attacker, which was successfully mitigated by Cloudflare, a leading cybersecurity firm. The details of this attack are deeply intertwined with the ASUS router authentication bypass vulnerability, which poses a significant threat to the security and stability of network infrastructure.
At its core, the ASUS router authentication bypass vulnerability is a critical flaw in the authentication mechanism employed by certain ASUS router models, allowing unauthenticated remote attackers to log in to these devices. This vulnerability has been assigned the CVE number CVE-2024-3080 and carries an estimated CVSS score of 9.8 on the Common Vulnerability Scoring System (CVSS), indicating that it is of extreme severity.
According to Cloudflare's analysis, the attacker(s) behind this DDoS attack exploited the aforementioned vulnerability in ASUS routers to launch a volumetric assault on the targeted networks. This attack peaked at an astonishing 3.8 terabits per second (Tbps) and 2.14 billion packets per second (pps), shattering previous records and showcasing the scale and ferocity of modern DDoS attacks.
The attackers predominantly utilized UDP traffic originating from compromised devices located across various countries, including Vietnam, Russia, Brazil, Spain, and the United States. It is worth noting that the use of compromised devices, such as MikroTik routers and DVRs, was common among these attacks, while high-bitrate attacks were linked to ASUS routers, likely due to exploitation of CVE-2024-3080.
The previous record-breaking volumetric DDoS attack observed by Cloudflare peaked at 2.6 Tbps, which is still an impressive figure but less severe than the 3.8 Tbps assault that broke records. Microsoft had reported a similarly high-volume DDoS attack in late 2021, peaking at 3.47 Tbps with a packet rate of 340 million pps.
Experts and cybersecurity professionals have been warning about the increasing frequency and scale of such attacks, which can overwhelm unprotected internet infrastructure, leading to significant disruptions and potential security breaches.
Cloudflare's defense mechanisms played a crucial role in mitigating this record-breaking DDoS attack. The company reported that it successfully defended against over 100 hyper-volumetric L3/4 DDoS attacks during the month of September, with many exceeding 2 billion packets per second and 3 Tbps. Notably, Cloudflare's detection and mitigation processes were fully autonomous, implying a high level of efficiency in its defenses.
The ASUS router authentication bypass vulnerability serves as a prime example of how critical it is to maintain up-to-date security patches and adhere to best practices regarding network security. Organizations that fail to address such vulnerabilities may be left exposed to severe DDoS attacks that could compromise their infrastructure and operations.
In light of this attack, cybersecurity professionals and organizations alike must remain vigilant in monitoring their systems for potential vulnerabilities and take proactive steps to enhance the resilience of their networks against such threats.
