Microsoft has now officially released the Windows 10 April 2018 Update, so read on to find out how to manually download and install the April 2018 Update. Microsoft has started the automatic rollout of the update, but it may still be a while before your device gets the April 2018 Update. If you don’t want to wait, then follow the steps below to download and install the Windows 10 April Update right now.

Before we demonstrate how to download and install the Windows 10 April 2018 Update, you should know that there is some inherent risk to installing major operating system updates, so we strongly advise that you backup your important data first. Luckily, we can show you all the best free backup software.

As the main WebScara page mentions, you don't need Git to install WebScara. A ZIP containing an up to date build of the master branch of the webscarab git tree can be found here. This file is rebuilt whenever new commits are pushed to the repository, and will always be the most up to date build of WebScarab available. Windows: double-click the installer jar file (complete installation instructions)) Features A framework without any functions is worthless, of course, and so WebScarab provides a number of plugins, mainly aimed at the security functionality for the moment. How To Install Webscarab read the request body from the stream. What platform can be seen in Figure 7. Basically, it will ignore any proxy settings if it thinks that If you are on the summary tab within Webscarab you will at least part of the supplied string=20 displaying the part that is not decodeable.

You should also create a system restore point, and in our guide on reinstalling Windows 10, we show you how.

Once that is done, read on to find out how to download and install the Windows 10 April Update right now.

How to download and install the Windows 10 April 2018 Update using the Update Assistant

If you’re experiencing issues with Windows Update, you can force your PC to download the Windows 10 April 2018 Update by using the Update Assistant tool.

To do this, head to the Windows 10 Update Assistant webpage and click 'Update now'.

The tool will download, then check for the latest version of Windows 10, which includes the April 2018 Update.

Once downloaded, run it, then select 'Update Now'. The tool will do the rest. Your PC will restart a few times – so save any work first – and then your PC will be updated with the April Update, while all your files and settings will remain where they were.

Remember, this will only work once the April 2018 Update is officially released.

How to manually download and install the Windows 10 April Update 2018

If you’re more into doing things yourself, there’s also a way to manually download the April Update 2018. This is a more complex way of doing things, however.

You can download the Windows 10 April 2018 Update 1803 (64-bit) ISO image directly from Microsoft.

There is also the Windows 10 April 2018 Update 1803 (32-bit) ISO file available if you have older 32-bit hardware.

Once the ISO file is downloaded, it can be burnt to a DVD or put on a bootable USB stick.

To make a bootable USB drive use Microsoft’s Windows USB/DVD Download Tool.

Once done, load up the file and follow the instructions to install the Windows 10 April 2018 Update.

Welcome to the WebScarab Project

WebScarab is a framework for analysing applications that communicate using the HTTP and HTTPS protocols. It is written in Java, and is thus portable to many platforms. WebScarab has several modes of operation, implemented by a number of plugins. In its most common usage, WebScarab operates as an intercepting proxy, allowing the operator to review and modify requests created by the browser before they are sent to the server, and to review and modify responses returned from the server before they are received by the browser. WebScarab is able to intercept both HTTP and HTTPS communication. The operator can also review the conversations (requests and responses) that have passed through WebScarab.

You may also be interested in testing the Next Generation of WebScarab.

Screenshots

Here's the main window of WebScarab. Check the WebScarab Getting Started guide for more screenshots of WebScarab in action.

Overview

There is no shiny red button on WebScarab, it is a tool primarily designed to be used by people who can write code themselves, or at least have a pretty good understanding of the HTTP protocol. If that sounds like you, welcome! Download WebScarab, sign up for the mailing list on the OWASP subscription page, and enjoy! You can read a brief tutorial to explain the basic workings.

WebScarab is designed to be a tool for anyone who needs to expose the workings of an HTTP(S) based application, whether to allow the developer to debug otherwise difficult problems, or to allow a security specialist to identify vulnerabilities in the way that the application has been designed or implemented.

Download

The canonical source repository for WebScarab is at GitHub. A zip archive of the tip of tree can be downloaded here.

Historical Versions:

Alternatively, you can download older builds of WebScarab from the OWASP Source Code Center at Sourceforge. Then install them likewise:

• Linux: java -jar ./webscarab-selfcontained-[numbers].jar
• Windows: double-click the installer jar file (complete installation instructions))

Features

How To Install Webscarab In Windows 8

A framework without any functions is worthless, of course, and so WebScarab provides a number of plugins, mainly aimed at the security functionality for the moment. Those plugins include:

• Fragments - extracts Scripts and HTML comments from HTML pages as they are seen via the proxy, or other plugins

• Proxy - observes traffic between the browser and the web server. The WebScarab proxy is able to observe both HTTP and encrypted HTTPS traffic, by negotiating an SSL connection between WebScarab and the browser instead of simply connecting the browser to the server and allowing an encrypted stream to pass through it. Various proxy plugins have also been developed to allow the operator to control the requests and responses that pass through the proxy.

• Manual intercept - allows the user to modify HTTP and HTTPS requests and responses on the fly, before they reach the server or browser.

• Beanshell - allows for the execution of arbitrarily complex operations on requests and responses. Anything that can be expressed in Java can be executed.

• Reveal hidden fields - sometimes it is easier to modify a hidden field in the page itself, rather than intercepting the request after it has been sent. This plugin simply changes all hidden fields found in HTML pages to text fields, making them visible, and editable.

• Bandwidth simulator - allows the user to emulate a slower network, in order to observe how their website would perform when accessed over, say, a modem.

• Spider - identifies new URLs on the target site, and fetches them on command.

• Manual request - Allows editing and replay of previous requests, or creation of entirely new requests.

• SessionID analysis - collects and analyzes a number of cookies to visually determine the degree of randomness and unpredictability. Note that this analysis is rather trivial, and does not do any serious checks, such as FIPS, etc.

• Scripted - operators can use BeanShell (or any other BSF supported language found on the classpath) to write a script to create requests and fetch them from the server. The script can then perform some analysis on the responses, with all the power of the WebScarab Request and Response object model to simplify things.

• Parameter fuzzer - performs automated substitution of parameter values that are likely to expose incomplete parameter validation, leading to vulnerabilities like Cross Site Scripting (XSS) and SQL Injection.

• Search - allows the user to craft arbitrary BeanShell expressions to identify conversations that should be shown in the list.

• Compare - calculates the edit distance between the response bodies of the conversations observed, and a selected baseline conversation. The edit distance is 'the number of edits required to transform one document into another'. For performance reasons, edits are calculated using word tokens, rather than byte by byte.

• SOAP - There is a plugin that parses WSDL, and presents the various functions and the required parameters, allowing them to be edited before being sent to the server. NOTE: This plugin is deprecated, and may be removed in the future. SOAPUI is streets beyond anything that Webscarab can do, or will ever do, and is also a free tool.

• Extensions - automates checks for files that were mistakenly left in web server's root directory (e.g. .bak, ~, etc). Checks are performed for both, files and directories (e.g. /app/login.jsp will be checked for /app/login.jsp.bak, /app/login.jsp~, /app.zip, /app.tar.gz, etc). Extensions for files and directories can be edited by user.

• XSS/CRLF - passive analysis plugin that searches for user-controlled data in HTTP response headers and body to identify potential CRLF injection (HTTP response splitting) and reflected cross-site scripting (XSS) vulnerabilities.

Training Material

How To Install Webscarab In Windows 7

Aung Khant (YGN Ethical Hacker Group, Myanmar) has created a series of WebScarab movies which can be found here.

There are slides of the presentation 'Uncovering Webscarab's Hidden Treasures', given at the OWASP EU Summit 2008, available here.

Future development

Features will probably include:

• Combining the Search and Compare plugins, so that you can compare only specific responses

• Improving the fuzzer, adding ability to follow redirects, or to specify the number of threads to use. Also, adding the ability to define what is (or isn't) interesting in the fuzz results, and save only interesting conversations to the summary.

Extensibility

How To Install Webscarab

As a framework, WebScarab is extensible. Each feature above is implemented as a plugin, and can be removed or replaced. New features can be easily implemented as well. The sky is the limit! If you have a great idea for a plugin, please let us know about it on the list.
