Cloudflare Mitigates 26 Million Request Per Second DDoS Attack

Published

on

Last week, Cloudflare automatically detected and mitigated a 26 million request per second DDoS attack — the largest HTTPS DDoS attack on record. The attack targeted a customer website using Cloudflare’s Free plan. Similar to the previous 15M rps attack, this attack also originated mostly from Cloud Service Providers as opposed to Residential Internet Service Providers, indicating the use of hijacked virtual machines and powerful servers to generate the attack — as opposed to much weaker Internet of Things (IoT) devices.

Record-breaking attacks
Over the past year, we’ve witnessed one record-breaking attack after the other. Back in August 2021, we disclosed a 17.2M rps HTTP DDoS attack, and more recently in April, a 15M rps HTTPS DDoS attack. All were automatically detected and mitigated by our HTTP DDoS Managed Ruleset which is powered by our autonomous edge DDoS protection system.

The 26M rps DDoS attack originated from a small but powerful botnet of 5,067 devices. On average, each node generated approximately 5,200 rps at peak. To contrast the size of this botnet, we’ve been tracking another much larger but less powerful botnet of over 730,000 devices. The latter, larger botnet wasn’t able to generate more than one million requests per second, i.e. roughly 1.3 requests per second on average per device. Putting it plainly, this botnet was, on average, 4,000 times stronger due to its use of virtual machines and servers.

Also, worth noting that this attack was over HTTPS. HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection. Therefore, it costs the attacker more to launch the attack, and for the victim to mitigate it. We’ve seen very large attacks in the past over (unencrypted) HTTP, but this attack stands out because of the resources it required at its scale.

Within less than 30 seconds, this botnet generated more than 212 million HTTPS requests from over 1,500 networks in 121 countries. The top countries were Indonesia, the United States, Brazil and Russia. About 3% of the attack came through Tor nodes. The top source networks were the French-based OVH (Autonomous System Number 16276), the Indonesian Telkomnet (ASN 7713), the US-based iboss (ASN 137922) and the Libyan Ajeel (ASN 37284).

The DDoS threat landscape
It’s important to understand the attack landscape when thinking about DDoS protection. When looking at our recent DDoS Trends report, we can see that most of the attacks are small, e.g. cyber vandalism. However, even small attacks can severely impact unprotected Internet properties. On the other hand, large attacks are growing in size and frequency — but remain short and rapid. Attackers concentrate their botnet’s power to try and wreak havoc with a single quick knockout blow — trying to avoid detection.

DDoS attacks might be initiated by humans, but they are generated by machines. By the time humans can respond to the attack, it may be over. And even if the attack was quick, the network and application failure events can extend long after the attack is over — costing you revenue and reputation. For this reason, it is recommended to protect your Internet properties with an automated always-on protection service that does not rely on humans to detect and mitigate attacks.

Helping build a better Internet
At Cloudflare, everything we do is guided by our mission to help build a better Internet. The DDoS team’s vision is derived from this mission: our goal is to make the impact of DDoS attacks a thing of the past. The level of protection that we offer is unmetered and unlimited — It is not bounded by the size of the attack, the number of the attacks, or the duration of the attacks. This is especially important these days because as we’ve recently seen, attacks are getting larger and more frequent.

Surge in Ransomware Attacks Has Made Effective Cyber Security and Defence a Top Priority

Published

Emad Fahmy, the Systems Engineering Manager for Middle East at NETSCOUT, speaks about the evolving threat landscape in the region

How has the security threat landscape evolved in recent months?
According to a 2021 survey by PwC, cybersecurity is a growing concern for organizations, with approximately 43% of Middle East CEOs planning to increase investments in cybersecurity and data privacy by 10% or more over the next three years. Moreover, 41% of these leaders think that their organization should be doing more to measure cybersecurity. The ever-evolving threat environment has made it increasingly necessary to be vigilant.

Cybercrimes continue to grow in terms of both complexity and frequency. Among the businesses that identify breaches or attacks, 21% lose money, data, or other assets, and 35% report being negatively impacted in other ways and suffering from wider business disruption. As such, it’s vital for enterprises to ensure the security of data, applications, networks, and critical business processes to stay competitive and thwart attackers. Depending on traditional security solutions and methodologies isn’t enough to combat the sophisticated attacks that target businesses today.

Is ransomware still an issue?
It is, unfortunately. The unprecedented surge in ransomware attacks has made effective cyber security and defence a top priority in today’s world. Every day, new ransomware attacks are reported by businesses and government authorities alike, not to mention the attacks that go unreported, and it seems like no one is immune.

Threat intelligence is vital to combat ransomware attacks. Threat intelligence is the study of the bad actors who perpetrate these attacks, along with the tactics and tools they use. This involves unveiling the bad actor’s attack methodologies and why they are targeting those victims. This knowledge is then turned into actionable insight that enterprises can access and comprehend. Empowered with this knowledge, enterprises can learn about their network’s vulnerabilities to actively defend against ransomware.

Companies have been trying to protect the endpoint for years. How can companies make sure endpoints are protected and monitored for attacks and mitigation?
As service providers increasingly focus on cloud services, edge computing, end-users, and endpoint devices, the traditional approach of utilizing distributed detection solutions in concert with centralized mitigation centres within the network is no longer enough. However, mitigation measures that are distributed out to the network edge necessitate both infrastructure and intelligent defence capabilities that are capable of working hand in hand across locations and platforms.

A more modern threat mitigation strategy involves distributing both detection and mitigation functions throughout the network to intercept threats nearer to the source. In this way, network operators can stop attacks upstream, instead of having to incur the cost of peering and transit link traffic that is only going to be discarded once it reaches a centralized scrubbing centre. By conducting the scrubbing as close as possible to the threat source, service providers can reduce any potential impact on traffic, helping to ensure high-quality service.
