This document proposes the AutoBLG framework to automatically generate URL blacklists. It has three main components:
1) URL Expansion uses existing malicious URLs to expand the search space through preprocessing, passive DNS databases, search engines and web crawlers.
2) URL Filtration reduces the expanded URLs using machine learning classifiers trained on HTML features and similarity searches.
3) URL Verification checks the filtered URLs for drive-by downloads using a honeypot, antivirus software, and VirusTotal.
The framework achieved a 99% reduction in URLs to verify while still finding new malicious URLs not in blacklists.
Beyond OWASP Top 10 - TASK October 2017Aaron Hnatiw
The OWASP Top 10 is the standard first reference we give web developers who are interested in making their applications more secure. It is also the categorization scheme we give to web vulnerabilities on our security assessment reports. And finally, and perhaps most frighteningly, it is the most common framework used by organizations for securing their web applications. But what if there was more to web application security than the OWASP Top 10? In this talk, we will discuss vulnerabilities that don't fit into the OWASP Top 10 categories, but are just as dangerous if present in a web application. Developers and pentesters will benefit from this talk, as both exploits and mitigations will be covered for each of the vulnerabilities.
This presentation is part of one of talk, I gave in Microsoft .NET Bootcamp. The contents are slightly edited to share the information in public domain. In this presentation, I tried to cover Application Security Tools that can be helpful for analyzing security threats as well as putting up some defense . This presentation will be useful for software architects/Managers,developers and QAs. Do share your feedback in comments.

Web scraping tools are software developed specifically to simplify the process of extracting data from websites. Data mining is a rather useful and commonly used process, but it can also easily turn into a complicated and messy activity and take a lot of time and effort.
A Novel Interface to a Web Crawler using VB.NET TechnologyIOSR Journals
Abstract : The number of web pages is increasing into millions and trillions around the world. To make
searching much easier for users, web search engines came into existence. Web Search engines are used to find
specific information on the World Wide Web. Without search engines, it would be almost impossible to locate
anything on the Web unless or until a specific URL address is known. This information is provided to search by
a web crawler which is a computer program or software. Web crawler is an essential component of search
engines, data mining and other Internet applications. Scheduling Web pages to be downloaded is an important
aspect of crawling. Previous research on Web crawl focused on optimizing either crawl speed or quality of the
Web pages downloaded. While both metrics are important, scheduling using one of them alone is insufficient
and can bias or hurt overall crawl process. This paper is all about design a new Web Crawler using VB.NET
Technology.

State of the Art Analysis Approach for Identification of the Malignant URLsIOSRjournaljce
Malicious URLs have been universally used to ascend various cyber attacks including spamming, phishing and malware. Malware, short term for malicious software, is software which is developed to penetrate computers in a network without the user’s permission or notification. Existing methods typically detect malicious URLs of a single attack type. Hence such detection systems are failed to protect the users from various attacks. Malware spreading widely throughout the area of network as consequence of this it becomes predicament in distributed computer and network systems. Malicious links are the place of origin of all attacks which circulated all over the web. Hence malicious URLs should be detected for the prevention of users from these malware attacks. In this paper we described a novel approach which analyze all types of attacks by identifying malicious URLs and secure the web users from them. This technique prevents the users from malignant URLs before visiting them. Therefore efficiency of web security gets maintained. For such anatomization we developed an analyzer which identifies URLs and examine as malicious or benign. We also developed five processes which crawl for suspicious URLs. This approach will prevent the users from all types of attacks and increase efficiency of web crawling phase.
The purpose is to conduct a website code audit and identify any obvious errors, inconsistencies, and potential sources of security breaches or violations of programming principles.
Browser isolation (isc)2 may presentation v2Wen-Pai Lu
Browser isolation provides protection for your devices from malware, phishing and many other web-based attacks. The air gaps between your browser and the devices you're on isolate all your browser activities from being affected your devices, thus protect you from malicious attacks.

Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
