Cloudflare named in 2024 Gartner® Magic Quadrant™ for Security Service Edge

Gartner has once again named Cloudflare to the Gartner® Magic Quadrant™ for Security Service Edge (SSE) report¹. We are excited to share that Cloudflare is one of only ten vendors recognized in this report. For the second year in a row, we are recognized for our ability to execute and the completeness of our vision. You can read more about our position in the report here.

Last year, we became the only new vendor named in the 2023 Gartner® Magic Quadrant™ for SSE. We did so in the shortest amount of time as measured by the date since our first product launched. We also made a commitment to our customers at that time that we would only build faster. We are happy to report back on the impact that has had on customers and the Gartner recognition of their feedback.

Cloudflare can bring capabilities to market quicker, and with greater cost efficiency, than competitors thanks to the investments we have made in our global network over the last 14 years. We believe we were able to become the only new vendor in 2023 by combining existing advantages like our robust, multi-use global proxy, our lightning-fast DNS resolver, our Continue reading

Cross compiling Rust to Ubiquiti access point

This is not the right way to do it, as will become abundantly clear. But it works.

Set up build environment

rustup toolchain install nightly
rustup component add rust-src --toolchain nightly
apt install {binutils,gcc}-mips-linux-gnu

Create test project

cargo new foo
cd foo

Build most of it

This will build for a while, then fail.

cargo +nightly build --release -Zbuild-std --target mips-unknown-linux-gnu

For some reason it’s trying to use cc to link. I tried putting this in Cargo.toml, but it does nothing:

[target.mips-unknown-linux-gnu]
linker = "mips-linux-gnu-gcc"

But I found a workaround.

Temporarily change /usr/bin/cc to point to the mips gcc

It does not work if you do this before the previous step.

PREV="$(readlink -v /usr/bin/cc)"
sudo rm /usr/bin/cc
sudo ln -s /usr/bin/mips-linux-gnu-gcc /usr/bin/cc

Link the program

Same command again

cargo +nightly build --release -Zbuild-std --target mips-unknown-linux-gnu

It should succeed. Yay.

Restore /usr/bin/cc

sudo rm /usr/bin/cc
sudo ln -s "${PREV?}" /usr/bin/cc

Change the “interpreter” to what the Ubiquiti system expects

cd target/mips-unknown-linux-gnu/release
patchelf --remove-needed ld.so.1 foo
patchelf --set-interpreter /lib/ld-musl-mips-sf.so.1 foo

Building it again

Probably easiest to rm -fr target, and go back to the step “Build most of it”.

Does it work?

$ ./foo
Hello, world!

Yay!

How Cloudflare Cloud Email Security protects against the evolving threat of QR phishing

In the ever-evolving landscape of cyber threats, a subtle yet potent form of phishing has emerged — quishing, short for QR phishing. It has been 30 years since the invention of QR codes, yet quishing still poses a significant risk, especially after the era of COVID, when QR codes became the norm to check statuses, register for events, and even order food.

Since 2020, Cloudflare’s cloud email security solution (previously known as Area 1) has been at the forefront of fighting against quishing attacks, taking a proactive stance in dissecting them to better protect our customers. Let’s delve into the mechanisms behind QR phishing, explore why QR codes are a preferred tool for attackers, and review how Cloudflare contributes to the fight against this evolving threat.

How quishing works

The impact of phishing and quishing are quite similar, as both can result in users having their credentials compromised, devices compromised, or even financial loss. They also leverage malicious attachments or websites to provide bad actors the ability to access something they normally wouldn’t be able to. Where they differ is that quishing is typically highly targeted and uses a QR code to further obfuscate itself from detection.

FRRouting Loopback Interfaces and OSPF Costs

TL&DR: FRRouting advertises the IP prefix on the lo loopback interface with zero cost.

Let’s start with the background story. When we added FRRouting containers support to netlab, someone decided to use lo0 as the loopback interface name. That device doesn’t exist in a typical Linux container, but it’s not hard to add it:

$ ip link add lo0 type dummy
$ ip link set dev lo0 up

DDoS threat report for 2024 Q1

Welcome to the 17th edition of Cloudflare’s DDoS threat report. This edition covers the DDoS threat landscape along with key findings as observed from the Cloudflare network during the first quarter of 2024.

What is a DDoS attack?

But first, a quick recap. 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.

Accessing previous reports

Quick reminder that you can access previous editions of DDoS threat reports on the Cloudflare blog. They are also available on our interactive hub, Cloudflare Radar. On Radar, you can find global Internet traffic, attacks, and technology trends and insights, with drill-down and filtering capabilities, so you can zoom in on specific countries, industries, and networks. There’s also a free API allowing academics, data sleuths, and other web enthusiasts to investigate Internet trends across the globe.

Unintended Consequences of IPv6 SLAAC

One of my friends is running a large IPv6 network and has already experienced a shortage of IPv6 neighbor cache on some of his switches. Digging deeper into the root causes, he discovered:

In my larger environments, I see significant neighbor table cache entries, especially on network segments with hosts that make many long-term connections. These hosts have 10 to 20 addresses that maintain state over days or weeks to accomplish their processes.

What’s going on? A perfect storm of numerous unrelated annoyances:
