Internet insights on 2024 elections in the Netherlands, South Africa, Iceland, India, and Mexico

2024 is being called by the media “the” year of elections. More voters than ever are going to the polls in at least 60 countries for national elections, plus the 27 member states of the European Union. This includes eight of the world’s 10 most populous nations, impacting around half of the world’s population.

To track and analyze these significant global events, we’ve created the 2024 Election Insights report on Cloudflare Radar, which will be regularly updated as elections take place.

Our data shows that during elections, there is often a decrease in Internet traffic during polling hours, followed by an increase as results are announced. This trend has been observed before in countries like France and Brazil, and more recently in Mexico and India — where elections were held between April 19 and June 1 in seven phases. Some regions, like Comoros and Pakistan, have experienced government-directed Internet disruptions around election time.

Below, you’ll find a review of the trends we saw in elections in South Africa (May 29), to Mexico (June 2), India (April 19 - June 1) and Iceland (June 1). This includes election-related shifts in traffic, as well at attacks. For example, during the Continue reading

Dutch political websites hit by cyber attacks as EU voting starts

The 2024 European Parliament election started in the Netherlands today, June 6, 2024, and will continue through June 9 in the other 26 countries that are part of the European Union. Cloudflare observed DDoS attacks targeting multiple election or politically-related Internet properties on election day in the Netherlands, as well as the preceding day.

These elections are highly anticipated. It’s also the first European election without the UK after Brexit.

According to news reports, several websites of political parties in the Netherlands suffered cyberattacks on Thursday, with a pro-Russian hacker group called HackNeT claiming responsibility.

On June 5 and 6, 2024, Cloudflare systems automatically detected and mitigated DDoS attacks that targeted at least three politically-related Dutch websites. Significant attack activity targeted two of them, and is described below.

A DDoS attack, short for Distributed Denial of Service attack, is a type of cyber attack that aims to take down or disrupt Internet services such as websites or mobile apps and make them unavailable for users. DDoS attacks are usually done by flooding the victim's server with more traffic than it can handle. To learn more about DDoS attacks and other types of attacks, visit our Learning Center.

European Union elections 2024: securing democratic processes in light of new threats

Between June 6-9 2024, hundreds of millions of European Union (EU) citizens will be voting to elect their members of the European Parliament (MEPs). The European elections, held every five years, are one of the biggest democratic exercises in the world. Voters in each of the 27 EU countries will elect a different number of MEPs according to population size and based on a proportional system, and the 720 newly elected MEPs will take their seats in July. All EU member states have different election processes, institutions, and methods, and the security risks are significant, both in terms of cyber attacks but also with regard to influencing voters through disinformation. This makes the task of securing the European elections a particularly complex one, which requires collaboration between many different institutions and stakeholders, including the private sector. Cloudflare is well positioned to support governments and political campaigns in managing large-scale cyber attacks. We have also helped election entities around the world by providing tools and expertise to protect them from attack. Moreover, through the Athenian Project, Cloudflare works with state and local governments in the United States, as well as governments around the world through international nonprofit partners, to provide Continue reading

Adopting OpenTelemetry for our logging pipeline

Cloudflare’s logging pipeline is one of the largest data pipelines that Cloudflare has, serving millions of log events per second globally, from every server we run. Recently, we undertook a project to migrate the underlying systems of our logging pipeline from syslog-ng to OpenTelemetry Collector and in this post we want to share how we managed to swap out such a significant piece of our infrastructure, why we did it, what went well, what went wrong, and how we plan to improve the pipeline even more going forward.

Background

A full breakdown of our existing infrastructure can be found in our previous post An overview of Cloudflare's logging pipeline, but to quickly summarize here:

• We run a syslog-ng daemon on every server, reading from the local systemd-journald journal, and a set of named pipes.
• We forward those logs to a set of centralized “log-x receivers”, in one of our core data centers.
• We have a dead letter queue destination in another core data center, which receives messages that could not be sent to the primary receiver, and which get mirrored across to the primary receivers when possible.

The goal of this project was to replace those syslog-ng instances as Continue reading

Extending local traffic management load balancing to Layer 4 with Spectrum

In 2023, Cloudflare introduced a new load balancing solution, supporting Local Traffic Management (LTM). This gives organizations a way to balance HTTP(S) traffic between private or internal servers within a region-specific data center. Today, we are thrilled to be able to extend those same LTM capabilities to non-HTTP(S) traffic. This new feature is enabled by the integration of Cloudflare Spectrum, Cloudflare Tunnels, and Cloudflare load balancers and is available to enterprise customers. Our customers can now use Cloudflare load balancers for all TCP and UDP traffic destined for private IP addresses, eliminating the need for expensive on-premise load balancers.

A quick primer

In this blog post, we will be referring to load balancers at either layer 4 or layer 7. This is, of course, referring to layers of the OSI model but more specifically, the ingress path that is being used to reach the load balancer. Layer 7, also known as the Application Layer, is where the HTTP(S) protocol exists. Cloudflare is well known for our layer 7 capabilities, which are built around speeding up and protecting websites which run over HTTP(S). When we refer to layer 7 load balancers, we are referring to HTTP(S)-based services. Our layer Continue reading

Disrupting FlyingYeti’s campaign targeting Ukraine

Cloudforce One is publishing the results of our investigation and real-time effort to detect, deny, degrade, disrupt, and delay threat activity by the Russia-aligned threat actor FlyingYeti during their latest phishing campaign targeting Ukraine. At the onset of Russia’s invasion of Ukraine on February 24, 2022, Ukraine introduced a moratorium on evictions and termination of utility services for unpaid debt. The moratorium ended in January 2024, resulting in significant debt liability and increased financial stress for Ukrainian citizens. The FlyingYeti campaign capitalized on anxiety over the potential loss of access to housing and utilities by enticing targets to open malicious files via debt-themed lures. If opened, the files would result in infection with the PowerShell malware known as COOKBOX, allowing FlyingYeti to support follow-on objectives, such as installation of additional payloads and control over the victim’s system.

Since April 26, 2024, Cloudforce One has taken measures to prevent FlyingYeti from launching their phishing campaign – a campaign involving the use of Cloudflare Workers and GitHub, as well as exploitation of the WinRAR vulnerability CVE-2023-38831. Our countermeasures included internal actions, such as detections and code takedowns, as well as external collaboration with third parties to remove the actor’s cloud-hosted malware.

Cloudflare acquires BastionZero to extend Zero Trust access to IT infrastructure

We’re excited to announce that BastionZero, a Zero Trust infrastructure access platform, has joined Cloudflare. This acquisition extends our Zero Trust Network Access (ZTNA) flows with native access management for infrastructure like servers, Kubernetes clusters, and databases.

Security teams often prioritize application and Internet access because these are the primary vectors through which users interact with corporate resources and external threats infiltrate networks. Applications are typically the most visible and accessible part of an organization's digital footprint, making them frequent targets for cyberattacks. Securing application access through methods like Single Sign-On (SSO) and Multi-Factor Authentication (MFA) can yield immediate and tangible improvements in user security.

However, infrastructure access is equally critical and many teams still rely on castle-and-moat style network controls and local resource permissions to protect infrastructure like servers, databases, Kubernetes clusters, and more. This is difficult and fraught with risk because the security controls are fragmented across hundreds or thousands of targets. Bad actors are increasingly focusing on targeting infrastructure resources as a way to take down huge swaths of applications at once or steal sensitive data. We are excited to extend Cloudflare One’s Zero Trust Network Access to natively protect infrastructure with user- and device-based policies Continue reading

Expanding Regional Services configuration flexibility for customers

This post is also available in Français, Español, Nederlands.

When we launched Regional Services in June 2020, the concept of data locality and data sovereignty were very much rooted in European regulations. Fast-forward to today, and the pressure to localize data persists: Several countries have laws requiring data localization in some form, public-sector contracting requirements in many countries require their vendors to restrict the location of data processing, and some customers are reacting to geopolitical developments by seeking to exclude data processing from certain jurisdictions.

That’s why today we're happy to announce expanded capabilities that will allow you to configure Regional Services for an increased set of defined regions to help you meet your specific requirements for being able to control where your traffic is handled. These new regions are available for early access starting in late May 2024, and we plan to have them generally available in June 2024.

It has always been our goal to provide you with the toolbox of solutions you need to not only address your security and performance concerns, but also to help you meet your legal obligations. And when it comes to data localization, we know that some of you need Continue reading

AI Gateway is generally available: a unified interface for managing and scaling your generative AI workloads

During Developer Week in April 2024, we announced General Availability of Workers AI, and today, we are excited to announce that AI Gateway is Generally Available as well. Since its launch to beta in September 2023 during Birthday Week, we’ve proxied over 500 million requests and are now prepared for you to use it in production.

AI Gateway is an AI ops platform that offers a unified interface for managing and scaling your generative AI workloads. At its core, it acts as a proxy between your service and your inference provider(s), regardless of where your model runs. With a single line of code, you can unlock a set of powerful features focused on performance, security, reliability, and observability – think of it as your control plane for your AI ops. And this is just the beginning – we have a roadmap full of exciting features planned for the near future, making AI Gateway the tool for any organization looking to get more out of their AI workloads.

Why add a proxy and why Cloudflare?

The AI space moves fast, and it seems like every day there is a new model, provider, or framework. Given this high rate of Continue reading

New Consent and Bot Management features for Cloudflare Zaraz

Managing consent online can be challenging. After you’ve figured out the necessary regulations, you usually need to configure some Consent Management Platform (CMP) to load all third-party tools and scripts on your website in a way that respects these demands. Cloudflare Zaraz manages the loading of all of these third-party tools, so it was only natural that in April 2023 we announced the Cloudflare Zaraz CMP: the simplest way to manage consent in a way that seamlessly integrates with your third-party tools manager.

As more and more third-party tool vendors are required to handle consent properly, our CMP has evolved to integrate with these new technologies and standardization efforts. Today, we’re happy to announce that the Cloudflare Zaraz CMP is now compatible with the Interactive Advertising Bureau Transparency and Consent Framework (IAB TCF) requirements, and fully supports Google’s Consent Mode v2 signals. Separately, we’ve taken efforts to improve the way Cloudflare Zaraz handles traffic coming from online bots.

IAB TCF Compatibility

Earlier this year, Google announced that websites that would like to use AdSense and other advertising solutions in the European Economic Area (EEA), the UK, and Switzerland, will be required to use a CMP that is approved by Continue reading

Cloudflare’s public IPFS gateways and supporting Interplanetary Shipyard

IPFS, the distributed file system and content addressing protocol, has been around since 2015, and Cloudflare has been a user and operator since 2018, when we began operating a public IPFS gateway. Today, we are announcing our plan to transition this gateway traffic to the IPFS Foundation’s gateway, maintained by the Interplanetary Shipyard (“Shipyard”) team, and discussing what it means for users and the future of IPFS gateways.

As announced in April 2024, many of the IPFS core developers and maintainers now work within a newly created, independent entity called Interplanetary Shipyard after transitioning from Protocol Labs, where IPFS was invented and incubated. By operating as a collective, ongoing maintenance and support of important protocols like IPFS are now even more community-owned and managed. We fully support this “exit to community” and are excited to support Shipyard as they build more great infrastructure for the open web.

On May 14th, 2024, we will begin to transition traffic that comes to Cloudflare’s public IPFS gateway to the IPFS Foundation’s gateway at ipfs.io or dweb.link. Cloudflare’s public IPFS gateway is just one of many – part of a distributed ecosystem that also includes Pinata, eth.limo, and Continue reading

Reclaiming CPU for free with Go’s Profile Guided Optimization

Golang 1.20 introduced support for Profile Guided Optimization (PGO) to the go compiler. This allows guiding the compiler to introduce optimizations based on the real world behaviour of your system. In the Observability Team at Cloudflare, we maintain a few Go-based services that use thousands of cores worldwide, so even the 2-7% savings advertised would drastically reduce our CPU footprint, effectively for free. This would reduce the CPU usage for our internal services, freeing up those resources to serve customer requests, providing measurable improvements to our customer experience. In this post, I will cover the process we created for experimenting with PGO – collecting representative profiles across our production infrastructure and then deploying new PGO binaries and measuring the CPU savings.

How does PGO work?

PGO itself is not a Go-specific tool, although it is relatively new. PGO allows you to take CPU profiles from a program running in production and use that to optimise the generated assembly for that program. This includes a bunch of different optimisations such as inlining heavily used functions more aggressively, reworking branch prediction to favour the more common branches, and rearranging the generated code to lump hot paths together to save on CPU Continue reading

East African Internet connectivity again impacted by submarine cable cuts

On Sunday, May 12, issues with the ESSAy and Seacom submarine cables again disrupted connectivity to East Africa, impacting a number of countries previously affected by a set of cable cuts that occurred nearly three months earlier.

On February 24, three submarine cables that run through the Red Sea were damaged: the Seacom/Tata cable, the Asia Africa Europe-1 (AAE-1), and the Europe India Gateway (EIG). It is believed that the cables were cut by the anchor of the Rubymar, a cargo ship that was damaged by a ballistic missile on February 18. These cable cuts reportedly impacted countries in East Africa, including Tanzania, Kenya, Uganda, and Mozambique. As of this writing (May 13), these cables remain unrepaired.

Already suffering from reduced capacity due to the February cable cuts, these countries were impacted by a second set of cable cuts that occurred on Sunday, May 12. According to a social media post from Ben Roberts, Group CTIO at Liquid Intelligent Technologies in Kenya, faults on the EASSy and Seacom cables again disrupted connectivity to East Africa, as he noted “All sub sea capacity between East Africa and South Africa is down.” A BBC Continue reading

Treasury and PNNL threat data now available for Financial sector customers to secure applications

Following the White House’s National Cybersecurity Strategy, which underscores the importance of fostering public-private partnerships to enhance the security of critical sectors, Cloudflare is happy to announce a strategic partnership with the United States Department of the Treasury and the Department of Energy’s Pacific Northwest National Laboratory (PNNL) to create Custom Indicator Feeds that enable customers to integrate approved threat intelligence feeds directly into Cloudflare's platform.

Our partnership with the Department of the Treasury and PNNL offers approved financial services institutions privileged access to threat data that was previously exclusive to the government. The feed, exposed as a Custom Indicator Feed, collects advanced insights from the Department of the Treasury and the federal government's exclusive sources. Starting today, financial institutions can create DNS filtering policies through Cloudflare’s Gateway product that leverage threat data directly from these government bodies. These policies are crucial for protecting organizations from malicious links and phishing attempts specifically targeting the financial sector.

This initiative not only supports the federal effort to strengthen cybersecurity within critical infrastructure including the financial sector, for which the Treasury is the designated lead agency, but also contributes directly to the ongoing improvement of our shared security capabilities.

Why we partnered Continue reading

Introducing Cloudflare for Unified Risk Posture

Managing risk posture — how your business assesses, prioritizes, and mitigates risks — has never been easy. But as attack surfaces continue to expand rapidly, doing that job has become increasingly complex and inefficient. (One global survey found that SOC team members spend, on average, one-third of their workday on incidents that pose no threat).  

But what if you could mitigate risk with less effort and less noise?

This post explores how Cloudflare can help customers do that, thanks to a new suite that converges capabilities across our Secure Access Services Edge (SASE) and web application and API (WAAP) security portfolios. We’ll explain:

• Why this approach helps protect more of your attack surface, while also reducing SecOps effort
• Three key use cases — including enforcing Zero Trust with our expanded CrowdStrike partnership
• Other new projects we’re exploring based on these capabilities

Cloudflare for Unified Risk Posture

Today, we’re announcing Cloudflare for Unified Risk Posture, a new suite of cybersecurity risk management capabilities that can help enterprises with automated and dynamic risk posture enforcement across their expanding attack surface. Today, one unified platform enables organizations to:

• Evaluate risk across people and applications: Cloudflare evaluates risk posed by people via Continue reading

Using Fortran on Cloudflare Workers

In April 2020, we blogged about how to get COBOL running on Cloudflare Workers by compiling to WebAssembly. The ecosystem around WebAssembly has grown significantly since then, and it has become a solid foundation for all types of projects, be they client-side or server-side.

As WebAssembly support has grown, more and more languages are able to compile to WebAssembly for execution on servers and in browsers. As Cloudflare Workers uses the V8 engine and supports WebAssembly natively, we’re able to support languages that compile to WebAssembly on the platform.

Recently, work on LLVM has enabled Fortran to compile to WebAssembly. So, today, we’re writing about running Fortran code on Cloudflare Workers.

Before we dive into how to do this, here’s a little demonstration of number recognition in Fortran. Draw a number from 0 to 9 and Fortran code running somewhere on Cloudflare’s network will predict the number you drew.

Try yourself on handwritten-digit-classifier.fortran.demos.cloudflare.com.

This is taken from the wonderful Fortran on WebAssembly post but instead of running client-side, the Fortran code is running on Cloudflare Workers. Read on to find out how you can use Fortran on Cloudflare Workers and how that demonstration works.

Wait, Fortran? Continue reading

Q1 2024 Internet disruption summary

This post is also available in 日本語, 한국어, Deutsch, Français, Español.

Cloudflare’s network spans more than 310 cities in over 120 countries, where we interconnect with over 13,000 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions. Thanks to recently released Cloudflare Radar functionality, this quarter we have started to explore the impact from a routing perspective, as well as a traffic perspective, at both a network and location level.

The first quarter of 2024 kicked off with quite a few Internet disruptions. Damage to both terrestrial and submarine cables caused problems in a number of locations, while military action related to ongoing geopolitical conflicts impacted connectivity in other areas. Governments in several African countries, as well as Pakistan, ordered Internet shutdowns, focusing heavily on mobile connectivity. Malicious actors known as Anonymous Sudan claimed responsibility for cyberattacks that disrupted Internet connectivity in Israel and Bahrain. Maintenance and power outages forced users offline, resulting in observed drops in traffic. And in Continue reading

Lessons from building an automated SDK pipeline

In case you missed the announcement from Developer Week 2024, Cloudflare is now offering software development kits (SDKs) for Typescript, Go and Python. As a reminder, you can get started by installing the packages.

// Typescript
npm install cloudflare

// Go
go get -u github.com/cloudflare/cloudflare-go/v2

// Python
pip install --pre cloudflare

Instead of using a tool like curl or Postman to create a new zone in your account, you can use one of the SDKs in a language that you’re already comfortable with or that integrates directly into your existing codebase.

import Cloudflare from 'cloudflare';

const cloudflare = new Cloudflare({
  apiToken: process.env['CLOUDFLARE_API_TOKEN']
});

const newZone = await cloudflare.zones.create({
  account: { id: '023e105f4ecef8ad9ca31a8372d0c353' },
  name: 'example.com',
  type: 'full',
});

Since their inception, our SDKs have been manually maintained by one or more dedicated individuals. For every product addition or improvement, we needed to orchestrate a series of manually created pull requests to get those changes into customer hands. This, unfortunately, created an imbalance in the frequency and quality of changes that made it into the SDKs. Even though the product teams would drive some of these changes, not all languages were covered and the SDKs Continue reading

Meta Llama 3 available on Cloudflare Workers AI

We are thrilled to give developers around the world the ability to build AI applications with Meta Llama 3 using Workers AI. We are proud to be a launch partner with Meta for their newest 8B Llama 3 model, and excited to continue our partnership to bring the best of open-source models to our inference platform.

Workers AI

Workers AI’s initial launch in beta included support for Llama 2, as it was one of the most requested open source models from the developer community. Since that initial launch, we’ve seen developers build all kinds of innovative applications including knowledge sharing chatbots, creative content generation, and automation for various workflows.  

At Cloudflare, we know developers want simplicity and flexibility, with the ability to build with multiple AI models while optimizing for accuracy, performance, and cost, among other factors. Our goal is to make it as easy as possible for developers to use their models of choice without having to worry about the complexities of hosting or deploying models.

As soon as we learned about the development of Llama 3 from our partners at Meta, we knew developers would want to start building with it as quickly as possible. Continue reading
