Mozilla has scrapped the cryptographic key behind Firefox and Thunderbird downloads for Linux after an unencrypted copy of it was committed by mistake to one of the company's own private code repositories. That key is how a user, or a Linux distribution packaging the browser, confirms a downloaded Firefox tarball came from Mozilla and was not tampered with. That decision carries a cost for

Most companies designed their resource permissions with a human user in mind. A senior engineer may be able to deploy to production, query a sensitive database, or revoke another user's access. Those privileges come with risk, but that risk has traditionally been bounded by two assumptions: the engineer will use human judgment, and the engineer can only act at human speed. An engineer who sees an unexpected result will usually stop and reconsider their actions. Any human being can only click, type, and review so much in a single day. The introduction of AI agents changes both thresholds. Their decisions are nondeterministic, and they can take the same action (or invoke the same tool) indefinitely, without getting tired or stopping for lunch. A plausible — but incorrect — decision can become thousands of incorrect actions before a human notices. Today, we're announcing new Cloudflare One capabilities to identify inspected MCP traffic, show which users and servers are generating it, and control direct connections on managed network paths. Combined with MCP Server Portals , these controls help administrators see whether agents are using an approved path, or somehow bypassing it. Model Context Protocol (MCP) servers give agents a common way to discover and invoke tools backed by third-party SaaS products, internal applications, and APIs. The underlying permissions are likely familiar; what changes is who makes each decision, and how quickly a bad decision can spread. Connecting an agent to one of these tools can take a single

AI has enabled employees across every team to build applications faster than ever before. But that speed is also what's keeping every CISO up at night: any employee can build an application, deploy it to the public Internet, and accidentally expose internal work or company data. Today, we're launching new tools to make it easy to keep your applications hosted on Workers private. You can now apply Cloudflare Access directly to a Worker or to every Worker in your account, so that your applications are behind your company login by default, without relying on each developer to set that up themselves. You can now: Set a policy at the account level to ensure that all preview and production deployments are behind your company login by default. Set a policy on a single application to ensure authentication is enforced on every domain associated with it, no matter how it's deployed. See exactly who visits your application. Get every authenticated user’s email, name, and groups directly in your code — no JWT (JSON Web Token) validation required. Deploy an internal platform where every deployment is private by default. We've open-sourced an example : an internal static site platform where every Worker deployed is private. Access on Workers: how it works When you enable Access on a Worker, Cloudflare enforces authentication before any request reaches your application code. It doesn't matter how the request gets to your Worker, whether it's through a custom domain, a route, a workers.dev subdomain, or a preview URL. If Access is on, the user h

It can be daunting to determine who’s responsible for showing ads on the websites we visit, or who’s harvesting data from the mobile apps we use every day. That information is already semi-public, but it is not easily parsed and traditionally much of it has remained walled away in the hands of large advertising platforms. Not anymore: A powerful and free new service called DecryptAds scrapes and correlates this adtech data and makes it simple to quickly learn a great deal about the entities that are tracking you. A Decryptads summary of the advertising partnerships declared by espn.com. The newly launched decryptads.com says it is constantly scraping the files that websites and apps make publicly available to disclose the companies that are permitted to run ads or collect user data. These files include: – ads.txt : all of the adtech companies and data brokers that may run ads or harvest data from the site; – app-ads.txt : entities that can harvest data from or display ads on mobile an

Suddenly, you’re in a room. You look around - oh, you’re surrounded by other new starters at your new job. Yes, it’s Monday, and you’re being onboarded. You know the drill - it’s the typical enterprise “please don’t be a bad person or we may have to fire you” speech. But, you know what’s coming soon. It’s your favorite part of the onboarding process when you’ve started a new role. It begins! The password policy requirements. You straighten your tie, because sure as heck, your SSLVPN credentials will not be the starting point for this organization. Not this time. Not again. You swore to yourself that you’d use a symbol this time. Wait, did they just say NetScalers? The world freezes around you. How are you back in the hellscape? You panic - what does a symbol matter in comparison to the traumatic nightmares you relive every day? You realize the truth - nobody cares whether your password has a symbol or not. It’s already over for you. Welcome back to another watchTowr Labs blog post. It’s been three years since the last publicly documented NetScaler RCE writeup.

CVE

At a time when looking down at our devices is a ritual in daily life, a natural phenomenon that demands our attention communally upward is a welcome event. On Wednesday, August 12, a total solar eclipse swept from the North Atlantic across Europe, moving over Iceland and northern Spain and Portugal, with a deep partial eclipse over the rest of Western Europe, all near local sunset. This was the first total solar eclipse to cross mainland Europe in twenty years, and it drew millions outdoors to witness the moon pass between Earth and the sun. As we saw during the 2026 World Cup and the last total eclipse in 2024 , online behavior is noticeably affected when an event at this scale takes place. In this blog post, we’ll use data from Cloudflare Radar to examine how Internet traffic shifted alongside the moon and the sun. Internet traffic dips align precisely with maximum obscuration In the figure above, we measured HTTP request volume in five-minute buckets across the affected countries on eclipse day, and compared it to a normal-day baseline. Each row is a country (except for Alaska) and each column is a five-minute slice of August 12, 2025, the day of the eclipse. The countries appear above in the order in which they saw the eclipse. The black diamonds mark the moment of maximum eclipse and the color shows the percent change in HTTP traffic versus the baseline (red = below normal, blue = above). We can see very clearly that the black diamonds overlay the darkest red, almost perfectly, signaling that as the eclipse deepened, Internet traffic decr

Since we launched Certificate Transparency Monitoring in public beta in 2019, we've been emailing subscribers whenever a new TLS certificate appears in a public Certificate Transparency (CT) log for one of their domains. Today, it's turned on for more than 650,000 customer domains. It's an early warning that someone, somewhere, has issued a certificate for a hostname in your zone, giving you a chance to spot a mis-issued certificate early. It's a useful signal, but it had a noise problem, and we felt it ourselves. Cloudflare issues a large volume of certificates on your behalf: Universal SSL renewals, certificates from Advanced Certificate Manager, and backup certificates. All of them are logged to public CT logs by design, because a certificate that isn't logged won't be trusted by major browsers like Google Chrome and Apple's Safari. So the same transparency that lets you monitor for mis-issuance also surfaces every certificate we issue for you. And issuance isn't a one-time event. Certificates are short-lived and renew automatically: a single Universal SSL certificate can renew as often as every 60 days , up to about six times a year. That cadence is set to increase, with the CA/Browser Forum having voted to cut the maximum certificate lifetime to 47 days by 2029, multiplying the routine renewals that fl

Microsoft today released updates to remedy at least 398 security vulnerabilities in its Windows operating systems and supported software, including one weakness that is already being actively exploited and two others that were publicly detailed prior to today. Image: Shutterstock, Mallika Home Studio. August’s overstuffed bundle of patch joy from Microsoft did not eclipse its recording breaking release of more than 570 security updates last month , but it is double June’s then-record batch of nearly 200 fixes . Microsoft has attributed the recent patch deluge to vulnerability discoveries aided by artificial intelligence, and experts roundly agree that Windows users should get used to the idea of Patch Tuesdays (the second Tuesday of each month) covering hundreds of newly discovered security flaws. Fully 42 of the 398 flaws that Microsoft patched today earned Redmond’s most-dire “critical” rating, meaning they are severe enough that malware or malcontents could exploit them to gain remote control over a Windows computer with little to no help from the user.

Every Signal chat starts the same way: the client asks the Signal server for the public key associated with your contact’s phone number. But how do you know the server gave you the right key? A compromised server could provide a false public key, allowing the client to encrypt messages to an attacker rather than the intended recipient. Until now, the only way to detect such malfeasance was to verify safety numbers with your contact in person or over a trusted channel. Signal recently launched an alternative: Automatic Key Verification , a feature that helps validate that your chats are secure without requiring direct safety number comparison . Trail of Bits built and operates one of the three auditors that make this system trustworthy. Our auditor, which is an independent implementation written from scratch, continuously checks that the Automatic Key Verification system behaves honestly. How key verification works Automatic Key Verification is a form of “key transparency” that makes mismatch attacks harder to hide by creating a globally consistent view of the set of public keys associated with each phone number. The Signal app now performs a periodic self-check to ensure that all keys stored in the global map for your account belong to your devices. If the app is unable to verify the log, or finds that not all keys are expected, the user is presented with a warning that “Automatic Key Verification is currently unavailable for your device.” Automatic Key Verification may also be unavailable for other reasons, as outlined in Signal’s documentation

Overview Two vulnerabilities have been identified in the Trusted Platform Module (TPM) 2.0 reference implementation: CVE-2026-6726 – Information leakage via falsified TPM keys. CVE-2026-6727 – A timing side-channel vulnerability in RSA OAEP decryption. An attacker with privileged access to a TPM command interface may be able to exploit these vulnerabilities by sending specially crafted TPM commands. Successful exploitation could allow the attacker to decrypt ciphertexts encrypted to affected TPM-managed RSA keys, including the RSA Endorsement Key (EK), or obtain credentials for falsified TPM keys, enabling forged TPM 2.0 attestations. These vulnerabilities are also documented by the Trusted Computing Group (TCG) in advisories - TCGVRT010 and TCGVRT0011 : Description Trusted Platform Module (TPM) technology provides hardware-backed cryptographic services for modern computing platforms. TPMs are designed to resist tampering and may be implemented as discrete chips, integrated hardware, firmware-based TPMs (fTPMs), or software implementations used in cloud and virtualized environments.

Welcome to the 25th edition of Cloudflare's DDoS Threat Report. This is the first half-year edition in the series: rather than publishing separate reports for the first and second quarters of 2026, we have combined our coverage of Q1 and Q2 into a single volume covering January through June 2026. The analysis is produced by Cloudforce One , Cloudflare’s Threat Intelligence organization, providing a comprehensive analysis of the evolving threat landscape of Distributed Denial of Service (DDoS) attacks based on data from the Cloudflare network . Key insights The 1 Tbps club grew. Cloudflare mitigated a combined 935 network-layer DDoS attacks exceeding 1 Tbps in the first half of 2026 and a +519% quarter-over-quarter surge between Q1 and Q2. The attack-vector center of gravity shifted from botnet floods to reflection and amplification. DNS-based attacks accounted for 34.3% of all network-layer activity in the first half of 2026, with DNS Floods alone climbing from 25.7% to 40.0% of network-layer attacks quarter-over-quarter. CLDAP Floods surged +580% quarter-over-quarter to become the #3 vector in Q2. Geopolitics and global events influence the landscape.

At the beginning of Agents Week, Rita shared that agents represent the next evolution of computing: not only as a new application of AI but also as a new class of software that’s shaping how people interact with technology, and how software interacts with the Internet. Over the last year or so, we set out to explore what this shift means for developers and customers building AI-native apps and the infrastructure needed to support them. As agents become more capable and autonomous, the challenges extend beyond the models themselves — to identity, communication, orchestration, memory, observability, and security. Over the past week we’ve shared how we’re bringing those pieces together across the Cloudflare platform to serve an Agentic Internet. Each day we presented new tools, products, and ideas toward building for an Internet where humans and agents cooperate instead of collide . Monday, August 3 Monday focused on the foundations for building and running intelligent, autonomous apps — the runtime and infrastructure agents rely on. Tuesday, August 4 Tuesday introduced the Agent Development Lifecycle (ADLC) and the primitives that take agentic software from prototype to production. Wednesday, August 5 Wednesday extended Zero Trust from users and devices to agents themselves — and we shared how we’re running it internally at Cloudflare.

CVE

Overview The OpenCart v4.2.0.0 extension installer contains a directory traversal vulnerability. The extension installation process extracts uploaded .zip files then uses the zip entry filenames as filesystem paths, without validating that the resolved path stays inside the intended directory. This vulnerability is tracked as CVE-2026-18412. Description OpenCart is a free, open‑source e‑commerce solution designed to help businesses build and manage online stores. OpenCart extensions are uploaded as zip files with .ocmod.zip extensions. Upon installation, the OpenCart v4.2.0.0 extension installer extracts these zip files, but does not validate that the extracted paths stay inside the intended extraction directory. An attacker can craft a malicious extension containing file path traversal sequences, such as ../ . With this vulnerability, an attacker can write files, such as a PHP web shell, into the webroot directory. Impact If a user with valid admininistrator credentials installs a malicious extension, it could allow a user to remotely execute code with the same privileges that OpenCart has on the target server. This includes the potential creation of a web shell, which could further enable remote execution of system-level commands. The vulnerability was confirmed against version 4.2.0.0, but other 4.x versions of OpenCart may be affected. Solution Unfortunately, OpenCart could not be reached to coordinate this vulnerability, and a patch is not available at the time of this writing. The CERT/CC recommends that OpenCart users update to the latest version and avoid installing extensions from unknown or untrusted sources. Additionally, OpenCart should be configured to run

We believe the Internet must be a force for good, and that it requires a foundation of trust. Nowhere is that trust more critical than in public service. Government agencies are the stewards of a nation’s most sensitive data. They protect national security, critical infrastructure , and the personal information of every citizen. Cloudflare’s mission is to help build a better Internet. A key part of that mission is giving public sector agencies the best technology to stay secure, fast, and reliable. That means meeting the highest possible standards. Today, we are proud to announce a major milestone: Cloudflare for Government has achieved FedRAMP Class D (High) certification status . We are honored to take this step with our sponsoring agency, the National Institute of Standards and Technology, whose global mission demands the highest level of security. We are also very excited to announce that we are using the new systems we developed for FedRAMP High as the foundation of our commitment to pursuing U.S. Department of Defense Impact Level 4 (DoD IL4) authorization.
