Cyber Jeff (Jeff Cyberman) needs your help to make sure we keep our network secure! **DONT LET JEFF DOWN!** If you served or worked for the US Army, you remember Cyber Jeff, the lovable protagonist in the yearly “Cyber Awareness Challenge” that was required for network access. Jeff may have been retired, but his legacy lives on in this figure. Great for reminding the office that Cyber Security is everyone's responsibility! *Stares in cyber awareness* [Makerworld - Cyber Awareness Jeff 3D Print](https://makerworld.com/en/models/2621608-cyber-jeff-jeff-cyberman-desk-figure?fbclid=IwY2xjawQ_cHRleHRuA2FlbQIxMQBzcnRjBmFwcF9pZBAyMjIwMzkxNzg4MjAwODkyAAEeoaOUmMuIs5AiwwEDaBx5qSC_WPw7n__x64eYGSihF4erhcYsAmXgzm7C24E_aem_xgrYEmHl43PlyY0v18tbRA#profileId-2893686)
We've all been there you run a Nmap scan, get 200 lines of output, then spend 20 minutes cross-referencing CVEs, writing up findings, and figuring out your next move. Multiply that across Nessus exports, Volatility dumps, BloodHound data, PCAP captures, and NetExec results and you're spending more time on analysis than actual testing. Syd takes all of that off your plate. Paste in your output from any tool Tenable/Nessus scan results, Nmap output, memory dumps, whatever and Syd extracts the facts, identifies the critical findings, maps attack paths, and gives you actionable next steps. What used to take 30-40 minutes of manual analysis takes seconds. What's in the box: Syd V3 Pro 6 tools: Nmap, Volatility, BloodHound, YARA, NetExec, PCAP Syd Enterprise Pro + full Metasploit integration (module browser, exploit launcher with live msfconsole, AI analysis of session output) Works with output from external tools (Tenable, Nessus, Qualys, etc.) just paste it in Anti-hallucination pipeline deterministic fact extraction before LLM ever touches the data RAG-powered knowledge base for each tool Runs 100% airgapped designed for secure environments Where Syd really shines is the workflow integration. Run your Tenable scan, export the results, paste them into Syd's Nmap page, and within seconds you've got a prioritised breakdown of every host, service, and vulnerability with recommended next steps and exploit suggestions. Same with BloodHound paste your enumeration data and Syd maps out the AD attack paths for you. It doesn't replace your tools, it makes the time between running them and writing your report almost zero. More tools coming for Enterprise: Sliver, Responder, Impacket, Burp Suite, Hashcat and so on.Happy to answer any questions or do a walkthrough if anyone's interested. 📧 [info@sydsec.co.uk](mailto:info@sydsec.co.uk) 🌐 [https://sydsec.co.uk](https://sydsec.co.uk)

For those who don't know it, GOAD (Game of Active Directory) is an open-source project by \*\*Orange Cyberdefense\*\* that provisions a fully functional but intentionally vulnerable AD environment: multiple domains, trust relationships, misconfigured delegations, weak ACLs, and more. It's essentially a legal, controlled playground for practicing AD attack chains (Kerberoasting, Pass-the-Hash, DCSync, lateral movement...) and building detection coverage against them. GOAD-Light is the lightweight version: 3 VMs (DC01, DC02, SRV02) across two domains with a bidirectional trust, running on Windows Server 2016. Manageable on a decent laptop. I deployed it on VirtualBox + Ubuntu 24.04 and figured I'd document the process properly since the official docs, while solid, can be a bit overwhelming when you're hitting errors at 1am. The guide covers the full deployment with Ansible, but more importantly it documents the actual errors I ran into: \\- \\\`NS\\\_ERROR\\\_FAILURE\\\` on Vagrant launch (vboxusers group not reloaded after install) \\- \\\`couldn't resolve module ansible.windows\\\` (Ansible Galaxy dependency and how to bypass it entirely) \\- \\\`unreachable=1\\\` on DC01 mid-provisioning (DC rebooting after domain promotion, not a real error, just needs patience) \\- VM conflicts from previous installs and how to clean them up cleanly Repo: \[https://github.com/Kjean13/goad-light-deployment\](https://github.com/Kjean13/goad-light-deployment)

Praetorian is excited to announce the release of Vespasian, a probabilistic API endpoint discovery, enumeration, and analysis tool. Vespasian watches real HTTP traffic from a headless browser or your existing proxy captures and turns it into API specifications (OpenAPI, GraphQL SDL, WSDL). We built it because pentesters spend the first days of every API engagement manually reconstructing documentation that should already exist. You know the scenario. You are three days into an API penetration test. Documentation was promised during scoping, and it existed at some point, but the Confluence page was last updated eighteen months ago and describes endpoints that have since been replaced. The Swagger UI returns a 404. The mobile app calls endpoints that don’t appear in any documentation at all. Nobody dropped the ball; the API just evolved faster than the docs. So you do what every pentester does: you open Burp Suite, click through the application for an hour, and start reading raw HTTP traffic. You spot JSON responses on /api/v2/ paths. GraphQL queries appear on a different subdomain. There’s a SOAP service that the frontend calls exactly once during login. Endpoint URLs are copied into a spreadsheet. You guess at parameter names. You manually reconstruct the API over the course of a couple days. This part of the project is informative, but it’s also a bottleneck. Vespasian reduces that bottleneck. It observes real HTTP traffic, either by crawling the target with a headless browser or by importing captures you’ve already made in Burp Suite, HAR, or mitmproxy, and generates API specifications automatically. REST endpoints become OpenAPI 3.0. GraphQL endpoints become SDL schemas. SOAP services become WSDL documents. You can try it yourself at

The next major breach hitting your clients probably won't come from inside their walls. It'll come through a vendor they trust, a SaaS tool their finance team signed up for, or a subcontractor nobody in IT knows about. That's the new attack surface, and most organizations are underprepared for it. Cynomi's new guide, Securing the Modern Perimeter: The Rise of Third-Party
Mixed Boolean-Arithmetic (MBA) obfuscation disguises simple operations like x + y behind tangles of arithmetic and bitwise operators. Malware authors and software protectors rely on it because no standard simplification technique covers both domains simultaneously; algebraic simplifiers don’t understand bitwise logic, and Boolean minimizers can’t handle arithmetic. We’re releasing CoBRA , an open-source tool that simplifies the full range of MBA expressions used in the wild. Point it at an obfuscated expression and it recovers a simplified equivalent: $ cobra-cli --mba "(x&y)+(x|y)" x + y $ cobra-cli --mba "((a^b)|(a^c)) + 65469 * ~((a&(b&c))) + 65470 * (a&(b&c))" --bitwidth 16 67 + (a | b | c) CoBRA simplifies 99.86% of the 73,000+ expressions drawn from seven independent datasets. It ships as a CLI tool, a C++ library, and an LLVM pass plugin. If you’ve hit MBA obfuscation during malware analysis, reversing software protection schemes, or tearing apart VM-based obfuscators, CoBRA gives you readable expressions back. Why existing approaches fall short The core difficulty is that verifying MBA identities requires reasoning about how bits and arithmetic interact under modular wrapping, where values silently overflow and wrap around at fixed bit-widths. An identity like (x ^ y) + 2 * (x & y) == x + y is true precisely because of this interaction, but algebraic simplifiers only see the arithmetic and Boolean minimizers only see the logic; neither can verify it alone.

A few important caveats: * it runs locally in the browser * it does not claim to detect malware through music * it is not a verdict engine * it is just an experimental visualization The idea was not “can analysts detect malware by ear?” but more: what happens if you represent file structure and characteristics as sound instead of another chart? I thought some people here might find it interesting, even if only as a weird security-adjacent experiment.

Overview Artifex's MuPDF contains an integer overflow vulnerability, CVE-2026-3308, in versions up to and including 1.27.0. Using a specially crafted PDF, an attacker can trigger an integer overflow resulting in out-of-bounds heap writes. This heap corruption typically causes the application to crash, but in some cases could be exploited to enable arbitrary code execution. Description Artifex MuPDF is a lightweight framework for viewing and converting PDF, XPS, and e-book files. A vulnerability exists in pdf_load_image_imp , which is responsible for preparing image data for decoding. The function processes image parameters including w (width), h (height), and bpc (bits per component), which are used to determine the amount of memory allocated during image decoding. The current implementation validates these parameters against SIZE_MAX rather than INT_MAX , but because stride calculations use integer-sized values, this check does not sufficiently protect against integer overflow when exceedingly large values are supplied. When the overflow occurs, the resulting corrupted values are passed into the fz_unpack_stream function, which expands packed image samples into a destination buffer during image decoding. Because this too-small overflow value is used to calculate the size of the destination buffer, not enough memory is allocated for the actual size of the image. This causes fz_unpack_stream to write beyond the bounds of the allocated heap buffer, resulting in a heap out-of-bounds write. Impact Successful exploitation results in a heap out-of-bounds write during PDF image decoding.
Posted by Adam Gavish, Google GenAI Security Team Indirect prompt injection (IPI) is an evolving threat vector targeting users of complex AI applications with multiple data sources, such as Workspace with Gemini. This technique enables the attacker to influence the behavior of an LLM by injecting malicious instructions into the data or tools used by the LLM as it completes the user’s query. This may even be possible without any input directly from the user. IPI is not the kind of technical problem you “solve” and move on. Sophisticated LLMs with increasing use of agentic automation combined with a wide range of content create an ultra-dynamic and evolving playground for adversarial attacks. That’s why Google takes a sophisticated and comprehensive approach to these attacks. We’re continuously improving LLM resistance to IPI attacks and launching AI application capabilities with ever-improving defenses.

Cloudflare data shows that 32% of traffic across our network originates from automated traffic . This includes search engine crawlers, uptime checkers, ad networks — and more recently, AI assistants looking to the web to add relevant data to their knowledge bases as they generate responses with retrieval-augmented generation (RAG). Unlike typical human behavior, AI agents , crawlers, and scrapers’ automated behavior may appear aggressive to the server responding to the requests. For instance, AI bots frequently issue high-volume requests, often in parallel. Rather than focusing on popular pages, they may access rarely visited or loosely related content across a site, often in sequential, complete scans of the websites. For example, an AI assistant generating a response may fetch images, documentation, and knowledge articles across dozens of unrelated sources. Although Cloudflare already makes it easy to control and limit automated access to your content, many sites may want to serve AI traffic. For instance, an application developer may want to guarantee that their developer documentation is up-to-date in foundational AI models, an e-commerce site may want to ensure that product descriptions are part of LLM search results, or publishers may want to get paid for their content through mechanisms such as pay per crawl . Website operators therefore face a dichotomy: tune for AI crawlers, or for human traffic. Given both exhibit widely different traffic patterns, current cache architectures force operators to choose one approach to save resources. In this

While his 408-character cipher was eventually cracked, the shorter “Z32” cipher that accompanied a map of the San Francisco Bay Area has remained unsolved for over five decades. The Z32 cipher consists of just 32 characters combining both letters and symbols. Alongside this cipher, the Zodiac included a chilling note: “The Map coupled with this code will tell you where the bomb is set. You have until next Fall to dig it up.”

Exactly 8 years ago today, we launched the 1.1.1.1 public DNS resolver , with the intention to build the world’s fastest resolver — and the most private one. We knew that trust is everything for a service that handles the "phonebook of the Internet." That’s why, at launch, we made a unique commitment to publicly confirm that we are doing what we said we would do with personal data. In 2020, we hired an independent firm to check our work , instead of just asking you to take our word for it. We shared our intention to update such examinations in the future. We also called on other providers to do the same, but, as far as we are aware, no other major public resolver has had their DNS privacy practices independently examined. At the time of the 2020 review, the 1.1.1.1 resolver was less than two years old, and the purpose of the examination was to prove our systems made good on all the commitments we made about how our 1.1.1.1 resolver functioned, even commitments that did not impact personal data or user privacy. Since then, Cloudflare’s technology stack has grown significantly in both scale and complexity. For example, we built an entirely new platform that powers our 1.1.1.1 resolver and other DNS systems. So we felt it was vital to review our systems, and our 1.1.1.1 resolver privacy commitments in particular, once again with a rigorous and independent review. Today, we are sharing the results of our most recent privacy examination by the same Big 4 accounting firm. Its independent examination is available on our compliance page . Foll
The cost of building software has drastically decreased. We recently rebuilt Next.js in one week using AI coding agents. But for the past two months our agents have been working on an even more ambitious project: rebuilding the WordPress open source project from the ground up. WordPress powers over 40% of the Internet . It is a massive success that has enabled anyone to be a publisher, and created a global community of WordPress developers. But the WordPress open source project will be 24 years old this year. Hosting a website has changed dramatically during that time. When WordPress was born, AWS EC2 didn’t exist. In the intervening years, that task has gone from renting virtual private servers, to uploading a JavaScript bundle to a globally distributed network at virtually no cost. It’s time to upgrade the most popular CMS on the Internet to take advantage of this change. Our name for this new CMS is EmDash. We think of it as the spiritual successor to WordPress. It’s written entirely in TypeScript. It is serverless, but you can run it on your own hardware or any platform you choose. Plugins are securely sandboxed and can run in their own isolate , via Dynamic Workers , solving the fundamental security problem with the WordPress plugin architecture. And under the hood, EmDash is powered by Astro , the fastest web framework for content-driven websites. EmDash is fully open source, MIT licensed, and available on GitHub . While EmDash aims to be compatible with WordPress functionality, no WordPress code was used to create EmDas

Code coverage is one of the most dangerous quality metrics in software testing. Many developers fail to realize that code coverage lies by omission: it measures execution, not verification. Test suites with high coverage can obfuscate the fact that critical functionality is untested as software develops over time. We saw this when mutation testing uncovered a high-severity Arkis protocol vulnerability , overlooked by coverage metrics, that would have allowed attackers to drain funds. Today, we’re announcing MuTON and mewt , two new mutation testing tools optimized for agentic use, along with a configuration optimization skill to help agents set up campaigns efficiently. MuTON provides first-class support for TON blockchain languages (FunC, Tolk, and Tact), while mewt is the language-agnostic core that also supports Solidity, Rust, Go, and more. The goal of mutation testing is to systematically introduce bugs (mutants) and check if your tests catch them, flagging hot spots where code is insufficiently tested. However, mutation testing tools have historically been slow and language-specific. MuTON and mewt are built to change that. To understand how, it helps to first understand what they’re replacing. The regex era Mutation testing dates to the 1970s, but for a long time, the technique rarely saw much adoption in the blockchain space as a software quality measurement. Testing frameworks are coupled tightly to target languages, making support for new languages expensive.

If you set LmCompatibilityLevel to 5 a couple years back and called it done, there's a good chance NTLMv1 is still running in your environment. Not because the setting doesn't work. Because it doesn't work the way you think it does. This isn't just aimed at people who never fully switched to Kerberos. It's also for the ones who are pretty sure they did. For people not deep into auth protocols: NTLMv1 and NTLMv2 are both considered unsafe today. NTLMv1 especially. It uses DES encryption, which with a weak password can be cracked in seconds. And because NTLM never sends your actual password (challenge-response, the hash gets passed not the plaintext), it's also wide open to pass-the-hash. An attacker intercepts the hash and reuses it to authenticate as you. Responder is the tool that makes this trivial and it's been around forever.Silverfort's research puts 64% of authentications in AD environments still on NTLM. Here's the actual problem with the registry fix. LMCompatibilityLevel is supposed to tell your DCs to reject NTLMv1 traffic and require NTLMv2 or Kerberos instead. Sounds reasonable. But enforcement runs through the Netlogon Remote Protocol (MS-NRPC), the mechanism application servers use to forward auth requests to your domain controllers. There's a structure in that protocol called NETLOGON\_LOGON\_IDENTITY\_INFO with a field called ParameterControl. That field contains a flag that can explicitly request NTLMv1, and your DC will honor it regardless of what Group Policy says. The policy controls what Windows clients send. It has no authority over what applications request on the server side. Any third party or homegrown app that hasn't been audited can still be sending NTLMv1 traffic and you'd have no idea. Silverfort built a POC to confirm this. They set the ParameterControl flag in a simulated misconfigured service and forced NTLMv1 authentications through a DC that was configured to block them. Worked. They reported it to Microsoft, Microsoft confirmed it but didn't classify it as a vulnerability. Their response was to announce full removal of NTLMv1 starting with Windows Server 2025 and Windows 11 24H2. So that's something, atleast. If you're not on those versions, you're still exposed and there's no patch coming. What you can do right now: turn on NTLM audit logging across your domain. Registry keys exist to capture all NTLM traffic so you can actually see what's authenticating how. From there, map every app using NTLM, whether primary or as a fallback, and look specifically for anything requesting NTLMv1 messages. That's your exposure.
The GPS Next-Generation Operational Control System was due for completion in 2016. Ten years later, the software for controlling the military’s GPS satellites still doesn’t work.
The University of North Georgia is one of the lesser known of the nation's senior military colleges (SMCs). But last week it beat out all the other five SMCs—and two of the elite service academies—in a capture-the-flag hacker contest staged at the Pentagon's Cyber Workforce Summit. The contest was designed by specialists from the Air Force Research Laboratory to be operationally realistic. In the first round, teams had to geo-locate a targeted individual through his devices and apps, prevent him from getting warning messages, and then call in an air strike to kill him. More details and quotes from UNG students—plus the team from The Citadel they bested in the final—in my latest story.

We're proud to introduce Programmable Flow Protection : a system designed to let Magic Transit customers implement their own custom DDoS mitigation logic and deploy it across Cloudflare’s global network. This enables precise, stateful mitigation for custom and proprietary protocols built on UDP. It is engineered to provide the highest possible level of customization and flexibility to mitigate DDoS attacks of any scale. Programmable Flow Protection is currently in beta and available to all Magic Transit Enterprise customers for an additional cost. Contact your account team to join the beta or sign up at this page . Programmable Flow Protection is customizable Our existing DDoS mitigation systems have been designed to understand and protect popular, well-known protocols from DDoS attacks. For example, our Advanced TCP Protection system uses specific known characteristics about the TCP protocol to issue challenges and establish a client’s legitimacy. Similarly, our Advanced DNS Protection builds a per-customer profile of DNS queries to mitigate DNS attacks. Our generic DDoS mitigation platform also understands common patterns across a variety of other well known protocols, including NTP, RDP, SIP, and many others. However, custom or proprietary UDP protocols have always bee

This post is part of a small blog series covering common Entra ID security findings observed during real-world assessments. Each article explores selected findings in more detail to provide a clearer understanding of the underlying risks and practical implications. Part 1: Privileged Foreign Enterprise Applications Introduction: What Are Unprotected Groups? Groups in Entra ID have various properties, such as: Group type: Security, Microsoft 365 (Unified), or Dynamic Security enabled: Yes / No Visibility: Public / Private Synced from on-premises: Yes / No Role-assignable: Yes / No These properties influence various aspects, such as whether Microsoft 365 resources are linked to the group, how membership is assigned, and how the group can be used for permission assignments. This blog post primarily focuses on security groups. Who Can Edit Security Groups? Some of these properties also determine who can edit the membership of a group. By default, numerous administrative roles can edit the membership of security groups, such as: User Administrator Groups Administrator Knowledge Administrator Knowledge Manager Windows 365 Administrator

Significantly, we're shifting more and more of the workload to the latter as all 3 of us at HIBP HQ get better at assigning workloads to machines. In addition to my use of my "PwnedClaw" bot to help catalogue and process data breaches, Stefan and I are both using GitHub Copilot in Visual Studio extensively, and Charlotte is using her own Telegram bot, "Pwny," plugged into OpenClaw to crawl all our content and look for inconsistencies while designing revised user interfaces. Over the last couple of weeks, I've spent US$854 on Claude tokens, which feels like a lot until you look at it like an employee doing work for you. But we've barely scratched the surface, and I can't wait to see the things we do with this in the weeks and months to come

HIBP Mega Update: Passkeys, k-Anonymity Searches, Massive Speed Enhancements and a Bulk Domain Verification API

Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite For a hobby project built in my spare time to provide a simple community service, Have I Been Pwned sure has, well, "escalated". Today, we support hundreds of thousands of website visitors each day, tens of millions of API queries, and hundreds of millions of password searches. We're processing billions of compromised records each year provided by breached companies, white hat researchers, hackers and law enforcement agencies. And it's used by every conceivable demographic: infosec pros, "mums and dads", customer support services, and, according to the data, more than half the Fortune 500 who are actively monitoring the exposure of their domains. So yeah, "escalated" seems fair! Amidst all the time spent processing data, we've been trying to figure out where to invest energy in building new stuff. In essence, data breaches are pretty simple: you've got a bunch of exposed email addresses attributed to a source, sitting next to a whole bunch of fields we describe with metadata. Our goal has always been to help people use this data to do good after bad things happen, and today we're launching a bunch of new features to do just that. So, here goes: New Features, New Plans In the beginning (ok, in "recent years"), there was one plan we referred to as "Pwned", and within that, there were various levels. For example, the entry-level plan has been "Pwned 1," and to this day, more than half our subscriptions are on it. That&apo
Overview Kyverno, versions 1.16.0 to present, contains an SSRF vulnerability in its CEL-based HTTP functions, which lack URL validation or namespace scoping and allow namespaced policies to trigger arbitrary internal HTTP requests. An attacker with only namespace-level permissions can exploit this to access sensitive internal services via the highly privileged Kyverno admission controller. Description Kyverno is an open-source, Kubernetes-native policy engine that functions as a dynamic admission controller for the Kubernetes API. It is designed to manage the lifecycle of cluster resources by validating, mutating, and generating configurations based on YAML-defined policies. Within a security context, the engine is frequently utilized to enforce Pod Security Standards, verify image signatures via Cosign, and audit resource configurations for compliance. Because Kyverno operates with high-level permissions to intercept and modify API requests, it represents a critical component of the cluster's security posture and trust boundary. A server-side request forgery vulnerability exists in Kyverno’s CEL-based HTTP functions (Get and Post) used by namespaced policy types in the policies.kyverno.io API group. Unlike Kyverno’s resource library, which enforces namespace boundaries, the HTTP library at pkg/cel/libs/http/http.go performs no URL validation or scoping; i.e., there are no blocklists, namespace restrictions, or destination checks. As a result, these policies can issue arbitrary HTTP requests from the Kyverno admission controller pod. Impact An authenticated attacker with only namespace-scoped permissions can create a malicious namespaced policy that sends an internal http.Get() request, captures the response in a CEL var
so, i built SPiCa: a high performance eBPF rootkit detection engine. the name comes from the Hatsune Miku song SPiCa, and the actual star Spica. Spica is a spectroscopic binary two stars orbiting so closely they look like one, i thought that was a sick concept for a security tool, so i built the architecture around it. SPiCa uses two completely independent observation channels to watch the kernel, if a rootkit tries to silence one, the other catches the discrepancy. the "binary star" architecture most basic rootkits bypass standard tools by hooking standard helper functions like bpf\_get\_current\_pid\_tgid(), SPiCa completely ignores those and establishes its own ground truth using two channels: the software channel (btf tracepoint): it attaches to sched\_switch but uses CO-RE to read the task\_struct directly from kernel memory. the hardware channel (nmi perf event): this is the fun part, it fires on hardware CPU cycle counters via Non-Maskable Interrupts (NMI) on every single logical core, a rootkit can't just cli/sti its way out of this in software; they'd have to reprogram the actual PMU registers. messing with the rootkits (build time obfuscation) a lot of modern rootkits hook the ring buffers and drop events that match hidden PIDs. to defeat this, SPiCa generates a random 64-bit key from /dev/urandom at compile time and bakes it directly into the eBPF bytecode, there are no BPF maps for the rootkit to look up, the engine XORs the PID and TGID before writing to the ring buffer, the rootkit inspects the event, sees a garbage PID that doesn't match its hidden list, and lets it pass right through to my userspace engine, which reverses the XOR. the userspace differential engine the userspace side is written in Rust/Tokio, it constantly reads both ring buffers and cross references them with /proc, if the math isn't mathing it throws an alert: \[DKOM\] - the kernel scheduled the process, but it's hidden from /proc \[TAMPER\] - the NMI hardware channel sees it, but the eBPF tracepoint never did (someone hooked the tracepoint) \[GHOST\] - it's sitting in /proc, but the kernel hasn't scheduled it in >5 seconds (spoofed /proc entry) \[SILENT\] - one channel suddenly stops sending events while the other is fine (someone detached a program or zeroed a struct) \[DUPE\] - a rootkit is forging task\_struct->tgid to impersonate a legit process, but the start times don't match try it out i built this mostly as a passion project to learn eBPF, but it actually works pretty well against standard evasion techniques. ```Bash # install the dependencies (arch/debian/fedora) make install-deps make install-tools # compile everything make all # run it (needs root) sudo ./target/release/spica ``` i know it's not a silver bullet (if someone hooks the NMI dispatch path directly, it's game over, though they'll probably kernel panic their box trying), but it was a ton of fun to build. repo is fully open-source (GPLv2), next up is spica-network, which is going to do the same dual-channel concept to catch hidden C2 traffic by diffing XDP and TC. let me know if you manage to break the logic!

Overview Four vulnerabilities have been identified in CrewAI, including remote code execution (RCE), arbitrary local file read, and server-side request forgery (SSRF). CVE-2026-2275 is directly caused by the Code Interpreter Tool. The other three vulnerabilities result from improper default configuration settings within the main CrewAI agent and associated Docker images. An attacker who can interact with a CrewAI agent that has the Code Interpreter Tool enabled may exploit these issues through prompt injection, ultimately chaining the vulnerabilities together. The vendor has provided a statement addressing some, but not all, of the reported vulnerabilities. Description CrewAI is a tool for building and orchestrating multi-agent AI systems. These agents are intended to work together to complete tasks, and developers define those tasks and workflows. CrewAI supports various tools, including one called the "Code Interpreter Tool", intended for execution of Python code within a secure Docker container. CVE-2026-2275 origintate from the Code Interpreter tool itself. The remaining vulnerabilities stem from insecure fallback behaviors and configuration issues in the CrewAI agent and Docker environment. Exploitation of CVE-2026-2275 may enable attackers to trigger the additional vulnerabilities. The vulnerabilities are listed below: CVE-2026-2275 The CrewAI CodeInterpreter tool falls back to SandboxPython when it cannot reach Docker, which can enable code execution through arbitrary C function calls. This vulnerability can be triggered if: allow_code_execution=True is enabled in the agent configuration, or if the Code Interpreter Tool is manually added to the agent by the developer. CVE-2026-2286 CrewAI contains a

Client-side skimming attacks have a boring superpower: they can steal data without breaking anything. The page still loads. Checkout still completes. All it needs is just one malicious script tag. If that sounds abstract, here are two recent examples of such skimming attacks: In January 2026, Sansec reported a browser-side keylogger running on an employee merchandise store for a major U.S. bank, harvesting personal data, login credentials, and credit card information. In September 2025, attackers published malicious releases of widely used npm packages . If those packages were bundled into front-end code, end users could be exposed to crypto-stealing in the browser. To further our goal of building a better Internet, Cloudflare established a core tenet during our Birthday Week 2025 : powerful security features should be accessible without requiring a sales engagement . In pursuit of this objective, we are announcing two key changes today: First, Cloudflare Client-Side Security Advanced (formerly Page Shield add-on ) is now available to self-serve customers. And second, domain-based threat intelligence is now complimentary for all customers on the free Client-Side Security bundle .

Please, We Beg, Just One Weekend Free Of Appliances (Citrix NetScaler CVE-2026-3055 Memory Overread Part 2)
Today, we woke up with a nagging feeling: what if Citrix had, in fact, patched multiple Memory Overread vulnerabilities as part of CVE-2026-3055? While we've been using our analysis from Part 1 (please read it first, as this post will be brief) to accurately identify exploitable Citrix NetScaler appliances across the watchTowr client base, we couldn't help but wonder: could there be more hiding in Citrix's patches? These thoughts, and worse, naturally come to us at 6 am on a Sunday morning. Welcome back to the hellscape, and yet another watchTowr Labs blog post. What we can confidently conclude, post-analysis, is that CVE-2026-3055 is not one singular memory overread vulnerability. In fact, this CVE ID has been assigned to at least two memory overread vulnerabilities , affecting the following endpoints: /saml/login /wsfed/pass
