This document discusses DOM-based cross-site scripting (XSS) vulnerabilities. It provides examples of DOM XSS issues that tools like DOMinator fail to detect. The key points are:
- DOM XSS arises due to client-side coding practices and the complex browser context, not just server-side issues.
- Examples show how input can be injected into the DOM without appearing in the page source, bypassing detection.
- Frameworks like YUI and jQuery are not inherently unsafe - it is insecure coding practices like insecure templating and lack of input sanitization that cause vulnerabilities.
- Browser behaviors like automatic decoding can also facilitate DOM XSS unless coding accounts for context changes.

Have-a-skate-with-Bob (HASB-KC) is a local charity that holds two Hockey Tournaments every year to raise money in the fight against Pancreatic Cancer. The FME Form software is used to integrate and exchange data via API, between Google Forms, Google Sheets, Stripe payments, SmartWaiver, and the GoDaddy email marketing tools to build a grass-roots Customer Relationship Management (CRM) system for the charity. The CRM is used to communicate effectively and readily with the participants of the hockey events and most importantly the local area sponsors of the event. Communication consists of a BLOG used to inform participants of event details including, the ever-important team rosters. Funds raised by these events are used to support families in the local area to fight cancer and support PanCan research efforts to find a cure against this insidious disease. FME Form removes the tedium and error-prone manual ETL processes against these systems into 1 or 2 workbenches that put the data needed at the fingertips of the event organizers daily freeing them to work on outreach and marketing of the events in the community.FME for Distribution & Transmission Integrity Management Program (DIMP & TIMP)

The National Fuels Treatments Initiative (NFT) is transforming wildfire mitigation by creating a standardized map of nationwide fuels treatment locations across all land ownerships in the United States. While existing state and federal systems capture this data in diverse formats, NFT bridges these gaps, delivering the first truly integrated national view. This dataset will be used to measure the implementation of the National Cohesive Wildland Strategy and demonstrate the positive impact of collective investments in hazardous fuels reduction nationwide. In Phase 1, we developed an ETL pipeline template in FME Form, leveraging a schema-agnostic workflow with dynamic feature handling intended for fast roll-out and light maintenance. This was key as the initiative scaled from a few to over fifty contributors nationwide. By directly pulling from agency data stores, oftentimes ArcGIS Feature Services, NFT preserves existing structures, minimizing preparation needs. External mapping tables ensure consistent attribute and domain alignment, while robust change detection processes keep data current and actionable. Now in Phase 2, were migrating pipelines to FME Flow to take advantage of advanced scheduling, monitoring dashboards, and automated notifications to streamline operations. Join us to explore how this initiative exemplifies the power of technology, blending FME, ArcGIS Online, and AWS to solve a national business problem with a scalable, automated solution.War_And_Cyber_3_Years_Of_Struggle_And_Lessons_For_Global_Security.pdf

Russia is one of the most aggressive nations when it comes to state coordinated cyberattacksand Ukraine has been at the center of their crosshairs for 3 years. This report, provided the State Service of Special Communications and Information Protection of Ukraine contains an incredible amount of cybersecurity insights, showcasing the coordinated aggressive cyberwarfare campaigns of Russia against Ukraine.
It brings to the forefront that understanding your adversary, especially an aggressive nation state, is important for cyber defense. Knowing their motivations, capabilities, and tactics becomes an advantage when allocating resources for maximum impact.
Intelligence shows Russia is on a cyber rampage, leveraging FSB, SVR, and GRU resources to professionally target Ukraines critical infrastructures, military, and international diplomacy support efforts.
The number of total incidents against Ukraine, originating from Russia, has steadily increased from 1350 in 2021 to 4315 in 2024, but the number of actual critical incidents has been managed down from a high of 1048 in 2022 to a mere 59 in 2024showcasing how the rapid detection and response to cyberattacks has been impacted by Ukraines improved cyber resilience.
Even against a much larger adversary, Ukraine is showcasing outstanding cybersecurity, enabled by strong strategies and sound tactics. There are lessons to learn for any enterprise that could potentially be targeted by aggressive nation states.

Reducing Conflicts and Increasing Safety Along the Cycling Networks of East-F...Safe Software
油
In partnership with the Belgian Province of East-Flanders this project aimed to reduce conflicts and increase safety along a cycling route between the cities of Oudenaarde and Ghent. To achieve this goal, the current cycling network data needed some extra key information, including: Speed limits for segments, Access restrictions for different users (pedestrians, cyclists, motor vehicles, etc.), Priority rules at intersections. Using a 360属 camera and GPS mounted on a measuring bicycle, we collected images of traffic signs and ground markings along the cycling lanes building up mobile mapping data. Image recognition technologies identified the road signs, creating a dataset with their locations and codes. The data processing entailed three FME workspaces. These included identifying valid intersections with other networks (e.g., roads, railways), creating a topological network between segments and intersections and linking road signs to segments and intersections based on proximity and orientation. Additional features, such as speed zones, inheritance of speed and access to neighbouring segments were also implemented to further enhance the data. The final results were visualized in ArcGIS, enabling analysis for the end users. The project provided them with key insights, including statistics on accessible road segments, speed limits, and intersection priorities. These will make the cycling paths more safe and uniform, by reducing conflicts between users.OWASP Barcelona 2025 Threat Model Library

Editor's Notes
- #4: Apresenta巽達o tomando como base explica巽達o em artigo de cowboycoded
- #6: Criar um 'plugin' que permita fazer reviews de um produto ou qualquer outra coisa
- #9: Polymorphic relationships allow you to have a single model that can be associated to an arbitrary number of other model types. Example For instance, let's say you have a contacts database utilizing two models, Person and Company. Both people and companies have addresses that you want to store in the database, and you want to be able to query against all addresses at once (say for a location-based search). Polymorphic associations make this easy in Rails. Let's assume that you already have your Person and Company models created and are just creating your Address model. When you create your migration you will denote the polymorphic relationship using references: http://wiki.rubyonrails.org/howtos/db-relationships/polymorphic
