If an autonomous AI agent interacts with your company's core intellectual property today, can your security team instantly name the person who authorized it? For most enterprises, the answer is a simple no. The rush to adopt internal AI tools has left a massive trail of administrative debt: orphaned agents (AI tools left running after their creator leaves the company) and standing privileges (
2026 is the year agent harnesses go to production. The software that controls the model’s access to the outside world — harnesses like Codex, Claude Code, OpenCode, Pi, and Project Think — has matured to the point where teams are deploying agents as real, load-bearing infrastructure, not just prototypes. But building agents that survive production is hard. We learned this firsthand building Project Think as our first-party agent harness. In working with our customers to run agents in production, we found a common set of distributed systems problems that every agent faces when running in the cloud. When an agent is interrupted, how can it automatically and gracefully resume from where it left off, without losing context or wasting tokens? How can agents run untrusted code securely? How can agents use the tools they were trained for? A harness can’t solve these problems on its own.

Weird DNS queries from svchost.exe (google.com.onion, wildcard + malformed domains) – anyone seen this on Windows?
I’m investigating a DNS-related alert and wanted to check if anyone has seen similar behavior in a Windows environment. We observed the following DNS queries from a Windows 11 host: * `google.com.onion` * `*google.com` * [`www.goooooooooooooooooooooooooooooooooooooooooooooooooooooooooogle.com`](http://www.goooooooooooooooooooooooooooooooooooooooooooooooooooooooooogle.com) * [`google.com`](http://google.com) All of these were generated within the same second by: * `svchost.exe` * Running as `NT AUTHORITY\SYSTEM` * Sysmon Event ID 22 (DNS query) Some key observations: * The `.onion` query returned **NXDOMAIN (DNS\_ERROR\_RCODE\_NAME\_ERROR)** * No follow-up connections or IP resolution were observed * The behavior looks like a burst of synthetic / malformed queries rather than user activity This pattern looks very similar to what people have reported on Samsung devices (MobileWIPS DNS probing / spoof detection), but this is a **Windows endpoint**. **Question:** 1. Has anyone seen similar DNS query patterns from `svchost.exe` on Windows endpoints? 2. Could this be: * DNS Client (Dnscache) behavior? * Some Windows network validation / spoof detection logic? * Or triggered indirectly by EDR/XDR tools interacting with DNS? 3. Any reliable way to map this definitively to a specific service under `svchost` using logs alone? At the moment, it looks benign (NXDOMAIN + no connections), but the `.onion` query is triggering alerts, so trying to confirm before suppressing. Appreciate any insights.
Twelve years ago this month, Cloudflare launched an ambitious project built on a simple idea: people shouldn’t be knocked offline just because someone more powerful disagrees with them.

Overview The SignalRGB kernel driver, SignalIo.sys , contains two vulnerabilities involving improper access control and unsafe memory handling. The device object is created with an overly permissive Discretionary Access Control List (DACL) that allows user-mode processes to access privileged hardware operations through input/output control (IOCTL) commands. Additionally, several IOCTL handlers are susceptible to NULL pointer dereference conditions, which further enables low-privilege users to trigger kernel crashes and cause Denial of Service (DoS). Version 1.3.7.0 of the SignalRGB driver remediates these vulnerabilities. Description SignalRGB is a Windows application used for RGB lighting control and hardware monitoring. Its kernel component, SignalIo.sys , provides the low-level interfaces required to access and interact with hardware resources. The SignalIo.sys driver exposes privileged functionality intended for administrative or security operations, but the device object is created without a restrictive security descriptor. Specifically, the driver does not apply security best practices by using either Security Descriptor Definition Language (SDDL) or the IoCreateDeviceSecure API, thereby allowing unprivileged user-mode processes to open handles to the device and issue privileged IOCTL requests. CVE-2026-8049 The \\.\SignalIo device object is created without an explicit SDDL security descriptor and without FILE_DEVICE_SECURE_OPEN . This results in overly permissive default access control, allowing any authenticated local user to obtain a handle to the

Overview Earlier this year, a team at Praetorian was building Constantine , our automated 0-day discovery engine. I wanted to find techniques worth folding into it, so on the side I started poking at the FreeBSD kernel with Claude Code, running on Opus 4.6, which was the latest Opus model at the time. A few days of work turned up real bugs and a weekend after that produced two working exploits capable of escaping from a FreeBSD jail. This article is part of a two-part series. In part one, I will be focusing on the methodology used to uncover the identified vulnerabilities and part two will focus on the methodology we leveraged to develop and exploit the vulnerabilities. It’s been several months since I disclosed roughly eight separate vulnerabilities to the FreeBSD security team. The reality is that this is a volunteer team and they are likely overwhelmed by the sheer number of vulnerabilities being identified within FreeBSD by various security researchers leveraging large language models. Because of this, we can really only publicly discuss a single vulnerability we reported CVE-2026-3038 , a fairly straight-
Microsoft has formally disclosed that it's working to release a patch to address a Defender zero-day codenamed RoguePlanet.

Adopting or migrating to a Zero Trust network architecture can be a daunting task. Before a single policy changes, teams have to recall how their network is actually built: which applications exist, their authentication and authorization constructs, how traffic flows between them, and any assumptions the current architecture makes. This hands-on process requires practitioners to decode the intent behind every security and routing policy in place. Today, we’re releasing the Cloudflare One stack, a set of skills you give to your agent to configure, deploy, and manage your Zero Trust environment for you. This toolkit is designed to help automate the process of learning an entirely new security suite and mapping your existing one into Cloudflare. Cloudflare has worked with thousands of customers through exactly this process. That repetition built expertise on where migrations stall, what questions come up every time, and what it takes to move forward. The Cloudflare One stack packages that expertise and makes it more accessible than ever. The agent gap in network security Teams are already using agents to write code, triage alerts, and automate workflows. Organizations are increasingly asking for Cloudflare-provided tooling to help agents execute on security workflows. On their own, agents are not trained on the nuances of an organization's specific network topology or vendor configurations. By providing prescriptive and authoritative guidance, organizations can layer this context into their existing toolkit to make better use of the security products they are already deploying. Cloudflare has long been the easiest-to-deploy SASE vendor in the market. The stack extends that philosophy to agents: it gives them the context, tools, and structured reasoning they need to o

Breaches don't always start with a zero-day. An exposed admin panel can get brute-forced, or credentials reused from a previous attack.

A flaw in the Google Cloud Vertex AI SDK for Python let an attacker with no access to a victim's project hijack the victim's machine learning model upload and run code inside Google's serving infrastructure. Palo Alto Networks Unit 42, which found and reported the bug through Google's bug bounty program, calls the technique "Pickle in the Middle" and said it saw no exploitation in the wild.
TL;DR: Sulla is an open source SMB secret scanner for discovering credentials exposed in SMB shares across enterprise networks. It leverages our recently released Titus Go library, resulting in an easy-to-use, adaptable, and highly performant standalone binary. Every network penetration tester knows the struggle: reviewing network shares for sensitive material is a painful must-do. With anything more than a handful of shares, manual review quickly becomes tedious if not outright infeasible. But automated secret scanning solutions produce nearly unworkable quantities of output, with actual secrets few and far between, not to mention requiring a Windows attack box. Sulla solves this issue by combining Praetorian’s years of secrets detection innovation with a clean, user-friendly interface purpose-built for internal networks. The result is a focused SMB secret scanner that pentesters can run from any Linux box and trust to surface high-signal findings. Sulla is also integrated end-to-end in the Guard, Praetorian’s all-in-one Continuous Threat Exposure Management platform, ensuring SMB secrets are identified as they appear in your environment. How Sulla Scans SMB Shares for Secrets Sulla automatically discovers readable SMB shares, traverses their file trees, and scans their contents for secr

When we first launched DMARC Management , it was driven by a simple belief: every domain on the Internet deserves strong email authentication, and cost should never be the reason it doesn't happen. As part of our mission to help build a better Internet, we made DMARC Management available for free to every Cloudflare customer. We wanted to give everyone the tools to understand and improve their DMARC posture without needing to hire an email security consultant or parse XML report files by hand. Today, we are taking that commitment further. Cloudflare DMARC Management is now generally available, with a redesigned experience built to help you reach full DMARC enforcement as easily as possible. The DMARC Management dashboard offers a unified view of your email authentication posture. What email authentication actually does for you Every time someone receives an email "from" your domain, their email provider asks a simple question: did the real owner of this domain actually send this? Without a way to answer that question, anyone can send an email pretending to be you and your recipients will have no way to tell the difference. Email authentication is the set of DNS records that answers that question. There are four protocols that protect your domain: SPF (Sender Policy Framework) tells receiving mail servers which IP addresses and services are allowed to send email on behalf of your domain. DKIM (DomainKeys Identified Mail) attaches a cryptographic signature to every email you send, so receiving servers can
Security teams have never had more IP data at their disposal.

Remus Stealer is a rapidly evolving Malware-as-a-Service infostealer that emerged in 2026. Remus also shifted from Lumma's 32-bit architecture and traditional resolvers to 64-bit with EtherHiding and enhanced anti-analysis (e.g., sandbox DLL checks, PST honeypot detection). * It utilizes EtherHiding, storing C2 addresses in Ethereum smart contracts to avoid takedowns. * The malware steals credentials, browser cookies, authentication tokens, and cryptocurrency wallet data. * Session theft is one of Remus's most dangerous capabilities because it can bypass MFA by stealing active session cookies directly from browser memory. * The malware shows strong technical similarities to Lumma Stealer and may represent its evolutionary successor. * Financial services, healthcare, government, technology firms, and MSPs are particularly attractive targets. * Common infection vectors include phishing, fake software downloads, malvertising, and fake CAPTCHA campaigns, as well as SEO poisoning and fake GitHub projects to trick tech-savvy users.

Today, we’re excited to share that key members of the team at Ensemble AI are joining Cloudflare to help accelerate our work in AI infrastructure and make it easier for developers to run powerful AI models efficiently at scale. Ensemble AI, founded in 2023 in San Francisco, has spent the last few years focused on one of the most important challenges in AI: making large models faster, smaller, and more cost-effective to serve, without sacrificing quality. The team has developed new approaches to model compression and efficient inference that are designed to reduce the memory, compute, and deployment overhead of large language models and multimodal architectures. As AI becomes a core part of how developers build applications, the economics of inference matter more than ever. Models are getting larger; workloads are becoming more dynamic. And customers increasingly expect AI to be available everywhere: globally distributed, fast, reliable, and affordable. Bringing the Ensemble AI team into Cloudflare strengthens our ability to make that possible. Incorporating Ensemble’s expertise The team at Ensemble AI has focused on preserving the structure inside modern AI models while reducing the cost of running them. Instead of treating model efficiency as only a quantization or hardware problem, Ensemble has explored new model building blocks that can make neural networks more compact and efficient at the architectural level. A core part of this work is NdLinear , a drop-in replacement for standard linear layers in transformer models that operates directly on multidimensional activations rather than flattening structure away. This enables models to preserve meaningful axes, such as heads, channels

In my blog article I analyze how random numbers in older PHP versions were generated. It turns out you can, under certain circumstances, derive the id of the process which generated a random number! While it has exactly 0 practical application, it was super fun to dig into the php's source code.

Why Use App-Level Auth When Every Database Has Auth? (Splunk Enterprise CVE-2026-20253 Pre-Auth RCE)
Three posts? In three days? Are we insane? We're home alone, there's no one to stop us, and we're up past bedtime. So, we need to talk about Splunk. On June 10th, Splunk published this CVE-2026-20253 advisory : It has everything that we love: No authentication requirements, An almost full-mark CVSS score, Claims to be a security product, Vulnerability name longer than the average piece of spaghetti. We immediately ha
Heimdal sysadmin Alex Panait spent weeks testing Claude Cowork inside the company. His verdict was blunt. It felt like onboarding a junior employee with no manager, no scoped access, and no clear accountability when something goes wrong. Except this one can delete your SharePoint. That is the uncomfortable reality behind autonomous AI desktop assistants. They […] The post Your Next Insider Threat May Be an AI Coworker appeared first on Heimdal Security Blog .
Security Insights provides actionable security recommendations for every Cloudflare account. To find these insights, we perform regular scans for all accounts, zones, and DNS records, looking for potential security risks and misconfigurations. However, two key issues emerged. First, our scans were too infrequent. Scans were only being performed every week or two, and therefore newly introduced security risks could remain undetected for up to two weeks. Second, automatic scanning was opt-in for many free plan accounts – meaning lots of accounts weren’t being scanned at all. The risks of infrequent or nonexistent scans are rising: as automated attacks accelerate, the window for detecting security misconfigurations is shrinking. Making sure that we’re finding these issues for all of our customers is crucial to our aim of building a better Internet for everyone. We calculated that to increase our scanning frequencies and enable automatic scanning for all accounts, we would need to increase our scanning throughput by around 10x on average – from 10 scans per second to 100 per second. But our system was already struggling with its load: millions of events were filling up our backlog waiting to be processed; our API was frequently timing out; our processes were crashing. We needed to fix our system, and we needed to make it scale . This is the story of how we increased scanning throughput for Security Insights by more than 10x, enabled security insights for millions of customers, and doubled our scanning frequency for all customers. Read on to find out how we achieved these improvements. How we scan for security insights At a high level, our automatic security scans are triggered by a scheduler. When an account or zone is due for a s
Cybersecurity failures now happen beyond the OSI stack. Faulty governance, the human factor, and AI tools create new attack surfaces. After seven years working across cybersecurity, cloud infrastructure, and Zero Trust architecture, Jayal Yadav explains how we got here and what organizations still get wrong. “The original seven layers of the OSI model still matter.

What happens when the bits of an RSA private key are heavily biased toward 0 instead of being randomly generated? The public key’s bits could be biased enough for us to detect these incorrectly generated keys in the wild. Together with Hanno Böck of the badkeys project, we found hundreds of unique keys that not only have this property, but can be quickly factored. We also found the bug that led to many of these keys and analyzed historical data to track the issue over time. Surprisingly, the pattern of 0 bits is often highly structured, allowing us to develop a powerful polynomial-based cryptanalytic technique that exploits the pattern. Figure 1: Two patterns of RSA moduli with repeated blocks of 0 bits seen in real-world examples. These “short-sleeve” keys, named for how the 0 bits don’t fully cover the limbs of the big integers, largely fell into two patterns. Pattern 1 remains unexplained, but we traced pattern 2 to a type mismatch in big-integer code from old versions of the CompleteFTP file transfer software. The CompleteFTP bug also generated vulnerable short-sleeve DSA keys, and we recovered 603 unique RSA private keys and 74 DSA keys from internet scans. If you used CompleteFTP to generate host keys between December 2016 and December 2023, CompleteFTP has released a tool to check whether your keys need to be regenerated. How we found
Marking Your Own Homework (Check Point Remote Access VPN IKEv1 Authentication Bypass CVE-2026-50751)
It is yet another day in this parallel universe of security, where the devices we bolt onto the edge of our networks to keep the bad people out are, with remarkable consistency, the exact thing that let the bad people in. While we’ve seemingly had a breather from traditional SSL VPN exploitation season (you know, the one where every edge appliance vendor takes it in turns to have a very bad week ), it’s now time to pull up a chair and welcome ourselves back to another group therapy session. Welcome back to another watchTowr Labs blog post. On the 8th of June 2026, Check Point released hotfixes for a pair of vulnerabilities in their Mobile Access/SSL VPN, Remote Access VPN, and Spark Firewall products, specifically within the "deprecated" IKEv1 VPN code. The headline act was CVE-2026-50751, with a CVSS score of 9.3 for an Authentication Bypass. For the AI threat intel bots scraping our posts every few minutes (yes, we know), these vulnerabilities align with CWE-1337 Fun Fridays. Naturally, when the words “VPN” and “Authentication Bypass” are in the vicinity, a CISA KEV listing is not far behind - and this time is no exception. Various sources indicate that this vulnerability has been exploited in the wild since 7th May 2026 (roughly a month before anyone received a patch), and that, per Check Point, there were "a few dozen targeted organizations".
