[FOSS Tool] WiFi-SpiderWeb V2.0: Active Cyber Defense for OpenWrt Routers with Live Radar Sweep (Python + SSE)
Hey everyone, I just updated my open-source project "WiFi-SpiderWeb" to Version 2.0! Based on initial feedback, I moved the system from a pure CLI tool into a fully automated, visual active defense ecosystem that runs entirely from a USB flash drive (ExtRoot). For those managing low-resource embedded hardware (like OpenWrt routers on MIPS/ARM), handling live Wi-Fi Deauthentication or Disassociation burst attacks can easily crash the system if memory isn't managed correctly. V2.0 solves this with a multi-threaded asynchronous architecture: 1. **The Backend Core**: Written in Python using Scapy with \`store=False\` (zero packet buffering in RAM) and kernel-side BPF filters so only management frames hit the daemon. 2. **The Attacker/Countermeasure Engine**: Fires back automatically via a thread-safe UNIX IPC socket (\`/tmp/spider\_ipc.sock\`) to: \* Spin up 10 virtual honeypots with randomized LAA MACs using native UCI commands to trap the scanner. \* Run a Tarpit flood loop designed to freeze stream dissection tables of tools like Wireshark or Nmap. \* Apply immediate Layer 2/3 hardware bans via ebtables/iptables. 3. **NEW Web Dashboard** (index.html & spider\_web.py): A lightweight 66KB self-contained UI utilizing Vanilla JS and Tailwind CSS. It communicates with the router via Server-Sent Events (SSE) and features a live Radar Sweep canvas that dynamically plots the estimated distance of the attacker based on raw RSSI telemetry! The POSIX-compliant \`usb\_autorun.sh\` handles hotplug integration, so it's entirely plug-and-play. The full implementation is open-source, and I'd love to get your feedback on optimization, especially regarding low-memory stability under heavy hostapd VAP reloads. 🔗 GitHub Repository: [https://github.com/badrrx/WiFi-SpiderWeb](https://github.com/badrrx/WiFi-SpiderWeb)

Hi all! I'm the creator of [Fibratus](https://fibratus.io/) \- the open-source security sensor for adversary tradecraft detection, protection, and hunting. Recently, I've been pushing detection engineering deeper into the **kernel** and **uncovered** what appears to be a novel approach to identifying attack patterns through kernel frame callstacks. User-space callstack telemetry has already become a powerful signal leveraged by modern security platforms. But kernel thread return addresses are largely unexplored territory. So, I made **Fibratus** capture kernel return addresses for different events (process creation, thread creation, file operations, etc.) and symbolize them into module paths, exposing the exact drivers and kernel subsystems traversed during event execution. The result is a radically richer execution narrative, one that reveals behavioral context traditional telemetry simply cannot see. This unlocks an entirely new detection surface. By incorporating kernel callstack summaries directly into detection rules, we can identify highly specific attack flows with exceptional precision. One example: detecting files dropped over SMB and subsequently executed: a classic **lateral movement** pattern. Check the screenshot for the detection rule example: [SMB Lateral Movement Rule](https://drive.google.com/drive-viewer/AKGpihZ118xdoIO8E7xsrBxYSzmfMO8qLEL_5H7Vjn1I-U7PLYGpc_5dWHHnr6V-AfXRfmBd17xEbYGIm-Gw7rgaDoZrAYPwopV-SQ=w1910-h848-rw-v1?auditContext=forDisplay) The kernel callstack becomes the connective tissue between stages of execution, providing durable attribution that is significantly more resistant to spoofing and telemetry tampering. We're actively building a new generation of detections powered by kernel subsystem context, driver-level execution paths, and low-level behavioral correlations that were previously inaccessible to defenders. If you’re interested in advanced detection engineering, kernel telemetry, or crafting next-generation behavioral rules, I’d love to connect and exchange ideas. Please let me know your thoughts and ideas, and we'll make sure to ship those rules in the next Fibratus release. Regards, Nedim

A malicious npm package name `js-logger-pack`, went through 29 versions on the registry which was looking innocuous logger and ending as a binary dropper. The payload it dropped was 81 MB of binary called MicrosoftSystem64 which is a full cross-platform RAT packaged as a Node.js Single Executable Application, so it shows up as a native binary to endpoint tools rather than a node process. And the clever bit was instead of sending the stolen data directly to a C2 server, it uploads everything to private **HuggingFace** datasets using an embedded API token. So all exfiltration traffic appears as normal HTTPS requests to a legitimate ML platform.

I built an independent benchmark with 20 real CVEs across 15 CWE categories, 5 models (3 OpenAI, 2 Poolside Laguna), three prompt conditions: full advisory, behavioral description only, and location only (file and function, no description of the flaw). I have three findings worth sharing: * **No model reliably fixes real vulnerabilities.** The best solve rate (gpt-5.5) is 50% overall and 60% under the most favorable condition. The failure modes (e.g, wrong-search drift, budget exhaustion mid-implementation, plausible-but-incomplete patches that pass every visible test) are structured and repeatable across models and tasks. * **Token cost varies 4x for equivalent outcomes.** The Laguna models consume 3–4x more tokens than OpenAI models of the same capability tier, with no improvement in solve rate. * **The locate condition is the benchmark's sharpest instrument.** Give a model only a file and function (no description of the flaw). Every model drops. The differences between models are within noise at this scale, but it's the condition that most closely resembles what a security researcher actually does: reading code cold and recognizing independently that something is wrong. Benchmark code and evaluation traces are open sourced.

Discovery During a recent network security assessment, we were working on an environment that was well-hardened – Patching was current, password policies were strong, and network segmentation was in place. So, as part of our enumeration of all network assets, we started looking for default credentials and this led us to multiple Canon enterprise printers configured with default administrator credentials. Enterprise printers are an interesting attack surface because it is common practice to have them configured with domain credentials. So, with administrative access, we tried to execute auth-back attacks by modifying the printer’s configuration to point to our server for credential capture or relay. However, network segmentation controls blocked this attack, as outbound controls prevented traffic from reaching our attacker-controlled subnet. We needed a different approach. We turned our attention to how the printer handled stored credentials. Specifically, we were curious to look at what happened to them during export. While exploring the printer’s administrative interface, we found a configuration export feature that allows administrators to back up device settings. This immediately raised a question: how were stored credentials being protected during export? Canon’s documentation states that exporting sensitive data requires encryption and the web interface presents encryption options (Security Level 1 and 2) that appear mandatory. However, we quickly discovered that these controls are implemented client-side without server-side validation. Vulnerability Canon imageRUNNER ADVANCE DX printers provide a configuration export feature that is accessible through the web management interface.

Immense stress has infected the brains of CISOs (chief information security officers) with malware, and they're looking to call it quits. The typical tenure of a CISO lasts just 18 to 26 months, compared to nearly five years for other C-suite roles, according to a report from research firm and publisher Cybersecurity Ventures. The job bridges the complex, technical side of a company and its business objectives, from finance to human resources to day-to-day operations.

In previous blog posts we’ve talked about getting nerd sniped . Today we’re going to talk about a kind of nerd sniping that any offensive security tool creator is familiar with; when your tool gets signatured. This normally kicks off a frustrating spiral of back and forth changes between the tool author and security vendors until the tool author runs out of resources to keep responding to changes. Like many parts of the security space, LLMs have changed how this story might end. The Classic Offensive Security Tooling Lifecycle There’s a lifecycle to most offensive security tooling. First you encounter a problem that’s common or problematic enough that you want to automate it, so you write a tool. Then you use that tool privately until you decide the time has arrived to open source it. This is a cool moment, you get to share your techniques with the community and if you’re really lucky, maybe the fundamental problem your tool exposes is fixed. Much more likely, once it’s open sourced it eventually gets signatured to the point that you

Overview Casdoor versions 2.362.0 and earlier contain several identity and access management vulnerabilities that enable broad authentication bypass and privilege escalation. These flaws relate to Casdoor’s Security Assertion Markup Language (SAML) processing, account binding, and token exchange mechanisms. An attacker able to interact with Casdoor’s authentication interface may impersonate users, bypass multifactor authentication (MFA), forge and replay assertions, and achieve persistent unauthorized access. Description Casdoor is an open-source identity and access management (IAM) platform and Model Context Protocol (MCP) gateway that provides authentication, single sign-on, and multi-protocol identity services. It is designed to centralize and streamline access control, allowing organizations to manage user identities and permissions across multiple applications and environments. CVE-2026-9090 Casdoor versions 2.362.0 and earlier contain a vulnerability that allows an attacker to bypass authentication by supplying an arbitrary signing certificate. The buildSpCertificateStore function extracts the X.509 certificate directly from the incoming SAMLResponse instead of using the trusted pre-configured Identity Provider certificate, allowing an attacker to forge assertions signed with an attacker-controlled key. CVE-2026-9091 A logic flaw in Casdoor's social‑login binding flow allows users to bypass configured MFA requirements. The binding‑rule code path in controllers/auth.go calls HandleLoggedIn directly without invoking checkMfaEnable . Any user authenticating via this path is logged in without MFA enforcement.

Cloudflare processes more than a billion events every second. Our network spans 330+ cities in 120+ countries. Behind every HTTP request, every Worker invocation, every R2 read operation, there is data, and a lot of it. For years, that data was not very easy to access. It lived in dozens of production databases, ClickHouse clusters, Kafka streams, Google Cloud buckets, BigQuery datasets, and a long tail of pipelines. To answer a simple question like "How many domains that signed up today are in the Top 100 by traffic?", an analyst at Cloudflare had to know which system to ask, what credentials to use, what query language to write, and whether the data they were looking at was sampled, fresh, or seven-days stale. As a result, it was difficult to glean informed insights from the data. To solve this problem, we built two in-house tools: Town Lake, Cloudflare's unified data analytics platform, and Skipper, an AI data agent that runs on top of it. Town Lake is a single SQL interface to everything Cloudflare knows, and Skipper is how anyone at Cloudflare can ask questions in plain English and get correct, auditable answers back in seconds. This is the story of how we built both. The shape of the problem If you have ever worked at a company that went through a hyper-growth period, you know what data sprawl looks like. Ours had a few specific symptoms: Too many disparate systems.

Each system had its own credentials, its own language, and its own retention policy. Sampled data. This is fine for dashboards, but doesn’t work for domains like billing. Our

There’s an increase in Device Code phishing activity, with Kali365 emerging as one of the most active PhaaS. In the last 24 hours alone, ANYRUN recorded 100+ related analysis sessions. The attack abuses legitimate Microsoft device authentication flows. Victims are shown a user code and instructed to enter it into a real Microsoft device auth page, allowing attackers to capture OAuth access tokens instead of passwords. The risk shifts from credential theft to token abuse, while significantly reducing the number of traditional phishing indicators typically used for detection and triage. Deobfuscated Kali365 JavaScript revealed that after a verification gate, the lure deploys a phishing page, launches a legitimate Microsoft device authentication flow, and then polls /api/status/<session\_id> for session states such as captured, expired, and declined. The code also contains lure-template generators for OneDrive, SharePoint, Teams, Outlook, and Voicemail, and a separate Google device-code authentication flow.

On Tuesday, May 26, Iran’s vice president announced that Internet access had started to be restored in the country after being cut off almost three months ago, following the launch of U.S. and Israeli attacks on February 28. Cloudflare Radar data confirms increased activity and indicates a partial restoration of the Internet in Iran. In this blog post, we’ll examine a range of data points that provide a lens into this prolonged shutdown – and the signs that Iran’s citizens are increasingly able to connect once again. As the situation continues to unfold, Radar will have the latest data on Iran’s connectivity . The first shutdown Iranian citizens have experienced two national Internet shutdowns this year. The first began on January 8 around 16:30 UTC (20:00 local time), and we explored the impact seen over the first few days in a blog post . Traffic from Iran remained near zero until January 21, when a small amount of traffic returned, only to disappear a little over 24 hours later. A similar brief restoration also occurred on January 25, before traffic recovered more fully beginning on January 27. The second shutdown In late February, as military strikes on Iran escalated, a second nationwide Internet shutdown began. That sweeping shutdown has persisted for nearly three months. The shutdown began on February 28. On that date, Cloudflare Radar observed a sharp drop in traffic from

A week after Dutch FIOD seized 800+ servers, the hosting network's ASN (AS209847) is still scanning at its normal daily rate
After FIOD seized 800+ servers and arrested two operators on May 18, the ELLIO research team reports that scanning from the network's ASN ranges has continued largely uninterrupted - and that while roughly a third of the recently-active ranges (including the legacy Stark blocks 94.131.105.0/24 and 92.118.232.0/24) have since been withdrawn from global routing, the surviving ranges under AS209847 (WorkTitans / THE.Hosting) are still announced and still scanning, at the network's normal daily rate. The sibling ASNs (AS213999 and the Moscow-based AS33993) remain routed and idle. The recent activity skews toward database and ICS/SCADA discovery = MongoDB, Redis, PostgreSQL, Oracle, LDAP, plus DNP3 and EtherNet/IP - alongside known-exploit probes like CVE-2017-17215 and WinRM.

Threat Intel: Lithuania Investigates B2B Credential Misuse Exposing 600,000 National Registry Records
The Lithuanian Prosecutor General’s Office and the Criminal Police Bureau have initiated a joint investigation into a large-scale data exfiltration incident targeting the **State Enterprise Centre of Registers**. The incident involved the unauthorized copying of over 600,000 records from the country's national Real Estate and Legal Entities Registers. Rather than exploiting an unpatched software vulnerability, the attack mechanics rely on a classic trust-boundary compromise. **The Entry Vector: Cross-Agency Credential Misuse (MITRE T1078)** Forensic tracking indicates that the threat actors executed a series of unauthorized connections originating from foreign infrastructure. The entry vector relied on valid, high-privilege B2B institutional login credentials assigned to external state departments authorized to query the central registry database. Independent statements from legislative and defense officials suggest the specific access pathway was carved out by compromising authenticated accounts belonging to the **Department of Migration under the Ministry of the Interior**. By hijacking these valid inter-agency connection points, the threat actors bypassed perimeter barriers, allowing them to issue massive queries to the backend database without triggering immediate anomaly blocks. **Exfiltration Scope & Impact Profile** The breach was initially identified by internal monitoring in early April 2026, but public disclosure was delayed due to the ongoing criminal inquiry. The exfiltrated data schemas consist of: * Full legal names, dates of birth, and unique national identification numbers. * Registered physical addresses, corporate entity structures, and detailed cadastral/property registry extracts. The Centre of Registers has confirmed that primary consumer-facing vectors - such as telephone contact details, email addresses, bank account numbers, or raw cadastral measurement files - were not part of the exfiltrated datasets. The primary operational risk is tactical intelligence gathering. Security analysts have pointed out that bulk access to unlisted residential addresses linked to legal entities can be leveraged by foreign intelligence services for target profiling, spear-phishing orchestration, or coercion of state personnel, diplomats, and military figures. **Incident Response & Remediation** Following the identification of the unauthorized bulk queries, the Centre of Registers implemented the following controls: 1. Immediate revocation and blocking of all compromised inter-agency institutional accounts. 2. Mandatory credential rotation and strict query-volume throttling across all API and web self-service gateways linked to external state dependencies. 3. The director of the Centre of Registers, Adrijus Jusas, formally stepped down on May 25 following administrative scrutiny regarding legacy IT infrastructure and monitoring gaps. While independent defense officials note the incident matches the operational signatures of state-aligned hybrid surveillance operations, official attribution from the Prosecutor General's Office remains open.

Encrypted DNS in 2026: DoH, DoT, DoQ and DoH3 protocol comparison — including DNS hijacking attack vectors and what each protocol actually prevents
The security angle on encrypted DNS is often oversimplified. DoH prevents ISP-level snooping and basic DNS hijacking, but doesn't protect against a compromised resolver. DoT is easier to detect and block, which has real implications for threat actors trying to exfiltrate via DNS. DoQ is interesting from a security perspective because QUIC's connection ID migration makes traffic correlation harder. Article includes benchmark data and practical server config — but mostly written for the "which threat model does each protocol address" question.
I published a technical write-up on an old OLX account takeover issue. The core bug was an OTP correctness leak inside the rate-limit state. After repeated invalid OTP attempts, the application showed a lockout message. However, blocked submissions did not become response-equivalent. Invalid codes during lockout still produced the invalid-code signal. The valid code during lockout removed that signal while keeping the lockout message. That made the lockout state act as an oracle for whether the OTP was correct. The broader impact came from reuse of the verification flow across account paths, including recovery/reset-style flows, plus weak session revocation behavior after password change. The write-up focuses on the response-difference behavior, why the validity window mattered, how the issue escalated to account takeover, and why lockout states must stop leaking success/failure information.
