Announcing WAF Attack Score Lite and Security Analytics for business customers

In December 2022 we announced the general availability of the WAF Attack Score. The initial release was for our Enterprise customers, but we always had the belief that this product should be enabled for more users. Today we’re announcing “WAF Attack Score Lite” and “Security Analytics” for our Business plan customers.

Looking back on “What is WAF Attack Score and Security Analytics?”

Vulnerabilities on the Internet appear almost on a daily basis. The CVE (common vulnerabilities and exposures) program has a list with over 197,000 records to track disclosed vulnerabilities.

That makes it really hard for web application owners to harden and update their system regularly, especially when we talk about critical libraries and the exploitation damage that can happen in case of information leak. That’s why web application owners tend to use WAFs (Web Application Firewalls) to protect their online presence.

Most WAFs use signature-based detections, which are rules created based on specific attacks that we know about. The signature-based method is very fast, has a low rate of false positives (these are the requests that are categorized as attack when they are actually legitimate), and is very efficient with most of the attack categories we know. However, Continue reading

Analyze any URL safely using the Cloudflare Radar URL Scanner

One of the first steps in an information security investigation is to gather as much context as possible. But compiling that information can become a sprawling task.

Cloudflare is excited to announce early access to a new, free tool — the Radar URL Scanner. Provide us a URL, and our scanner will compile a report containing a myriad of technical details: a phishing scan, SSL certificate data, HTTP request and response data, page performance data, DNS records, whether cookies are set to secure and HttpOnly, what technologies and libraries the page uses, and more.

Let’s walk through a report on John Graham-Cumming’s blog as an example. Conveniently, all reports generated will be publicly accessible.

The first page is the summary tab, and you’ll see we’ve broken all the available data into the following categories: Security, Cookies, Network, Technology, DOM, and Performance. It’s a lot of content so we will jump through some highlights.

In the Summary tab itself, you’ll notice the submitted URL was https://blog.jgc.org. If we had received a URL short link, the scanner would have followed the redirects and generated a report for the final URL.

The Security tab presents information to help determine whether a Continue reading

Using the power of Cloudflare’s global network to detect malicious domains using machine learning

Cloudflare secures outbound Internet traffic for thousands of organizations every day, protecting users, devices, and data from threats like ransomware and phishing. One way we do this is by intelligently classifying what Internet destinations are risky using the domain name system (DNS). DNS is essential to Internet navigation because it enables users to look up addresses using human-friendly names, like cloudflare.com. For websites, this means translating a domain name into the IP address of the server that can deliver the content for that site.

However, attackers can exploit the DNS system itself, and often use techniques to evade detection and control using domain names that look like random strings. In this blog, we will discuss two techniques threat actors use – DNS tunneling and domain generation algorithms – and explain how Cloudflare uses machine learning to detect them.

Domain Generation Algorithm (DGA)

Most websites don’t change their domain name very often. This is the point after all, having a stable human-friendly name to be able to connect to a resource on the Internet. However, as a side-effect stable domain names become a point of control, allowing network administrators to use restrictions on domain names to enforce policies, for example Continue reading

Detecting API abuse automatically using sequence analysis

Today, we're announcing Cloudflare Sequence Analytics for APIs. Using Sequence Analytics, Customers subscribed to API Gateway can view the most important sequences of API requests to their endpoints. This new feature helps customers to apply protection to the most important endpoints first.

What is a sequence? It is simply a time-ordered list of HTTP API requests made by a specific visitor as they browse a website, use a mobile app, or interact with a B2B partner via API. For example, a portion of a sequence made during a bank funds transfer could look like:

Why is it important to pay attention to sequences for API security? If the above API received requests for POST /api/v1/transferFunds without any of the prior requests, it would Continue reading

Automatically discovering API endpoints and generating schemas using machine learning

Cloudflare now automatically discovers all API endpoints and learns API schemas for all of our API Gateway customers. Customers can use these new features to enforce a positive security model on their API endpoints even if they have little-to-no information about their existing APIs today.

The first step in securing your APIs is knowing your API hostnames and endpoints. We often hear that customers are forced to start their API cataloging and management efforts with something along the lines of “we email around a spreadsheet and ask developers to list all their endpoints”.

Can you imagine the problems with this approach? Maybe you have seen them first hand. The “email and ask” approach creates a point-in-time inventory that is likely to change with the next code release. It relies on tribal knowledge that may disappear with people leaving the organization. Last but not least, it is susceptible to human error.

Even if you had an accurate API inventory collected by group effort, validating that API was being used as intended by enforcing an API schema would require even more collective knowledge to build that schema. Now, API Gateway’s new API Discovery and Schema Learning features combine to automatically Continue reading

Announcing Cloudflare Fraud Detection

The world changed when the COVID-19 pandemic began. Everything moved online to a much greater degree: school, work, and, surprisingly, fraud. Although some degree of online fraud has existed for decades, the Federal Trade Commission reported consumers lost almost $8.8 billion in fraud in 2022 (an over 400% increase since 2019) and the continuation of a disturbing trend. People continue to spend more time alone than ever before, and that time alone makes them not just more targeted, but also more vulnerable to fraud. Companies are falling victim to these trends just as much as individuals: according to PWC’s Global Economic Crime and Fraud Survey, more than half of companies with at least $10 billion in revenue experienced some sort of digital fraud.

This is a familiar story in the world of bot attacks. Cloudflare Bot Management helps customers identify the automated tools behind online fraud, but it’s important to note that not all fraud is committed by bots. If the target is valuable enough, bad actors will contract out the exploitation of online applications to real people. Security teams need to look at more than just bots to better secure online applications and tackle modern, online fraud.

First Steps in IPv6 Deployments

Even though IPv6 could buy its own beer (in US, let alone rest of the world), networking engineers still struggle with its deployment – one of the first questions I got in the ipSpace.net Design Clinic was:

We have been tasked to start IPv6 planning. Can we discuss (for enterprises like us who all of the sudden want IPv6) which design paths to take?

I did my best to answer this question and describe the basics of creating an IPv6 addressing plan. For even more details, watch the IPv6 webinars (most of them at least a few years old, but nothing changed in the IPv6 world in the meantime apart from the SRv6 madness).

How network pros can fight being squeezed out of cloud decisions

There's a rumbling in the cloud as network professionals increasingly seek to reclaim what they believe is their rightful place in the enterprise management hierarchy.Network knowledge is now widespread within many other IT disciplines. "This means it's now sometimes easy for other teams to assume that they know all they need to know about networking, so they don't need to bother the network team," observes Josh Stephens, CTO of multi-cloud network automation provider BackBox.Network pros have unique perspectives. When it comes to multicloud decision-making, IT, cloud, cybersecurity, and network professionals all bring different perspectives and talents to the table. "IT teams have a deep understanding of the organization's overall technology, while cloud teams have expertise in cloud-based technology solutions, and cybersecurity teams have a thorough understanding of [cloud] security risks," says Dan Dulac, vice president of solutions strategy at network infrastructure provider Extreme Networks. Combining the insights of these experts, along with network professionals, is the best way for organizations to make informed decisions about their multicloud strategy, he says.To read this article in full, please click here

How sophisticated scammers and phishers are preying on customers of Silicon Valley Bank

By now, the news about what happened at Silicon Valley Bank (SVB) leading up to its collapse and takeover by the US Federal Government is well known. The rapid speed with which the collapse took place was surprising to many and the impact on organizations, both large and small, is expected to last a while.

Unfortunately, where everyone sees a tragic situation, threat actors see opportunity. We have seen this time and again - in order to breach trust and trick unsuspecting victims, threat actors overwhelmingly use topical events as lures. These follow the news cycle or known high profile events (The Super Bowl, March Madness, Tax Day, Black Friday sales, COVID-19, and on and on), since there is a greater likelihood of users falling for messages referencing what’s top of mind at any given moment.

The SVB news cycle makes for a similarly compelling topical event that threat actors can take advantage of; and it's crucial that organizations bolster their awareness campaigns and technical controls to help counter the eventual use of these tactics in upcoming attacks. It’s tragic that even as the FDIC is guaranteeing that SVB customers’ money is safe, bad actors are attempting to steal that Continue reading
