SSL Error Reporting is an opt-in mechanism to allow users to send data on such violations to mozilla. Payload Format An example report: { "hostname":"example.com", "port":443, "timestamp":1413490449, "errorCode":-16384, "failedCertChain":[ ], "userAgent":"Mozilla/5.0 (X11; Linux x86_64; rv:36.0) Gecko/20100101 Firefox/36.0", "version":1, "build":"20141022164419", "product":"Firefox", "channel":"default" } Where the data represents the following: “hostname” The name of the host the connection was being made to. “port” The TCP port the connection was being made to. “timestamp” The (local) time at which the report was generated. Seconds since 1 Jan 1970, UTC. “errorCode” The error code. This is the error code from certificate verification. Here’s a small list of the most commonly-encountered errors: https://wiki.mozilla.org/SecurityEngineering/x509Certs#Error_Codes_in_ Firefox In theory many of the errors from sslerr.h, secerr.h, and pkixnss.h could be encountered. We’re starting with just MOZILLA_PKIX_ERROR_KEY_PINNING_FAILURE, which means that key pinning failed (i.e. 1 Mozilla Source Tree Docs, Release 55.0a1 there wasn’t an intersection between the keys in any computed trusted certificate chain and the expected list of keys for the domain the user is attempting to connect to). “failedCertChain” The certificate chain which caused the pinning violation (array of base64 encoded PEM) “user agent” The user agent string of the browser sending the report “build” The build ID “product” The product name “channel” The user’s release channel Preferences The following preferences are used by SSL Error reporting: “security.ssl.errorReporting.enabled” Should the SSL Error Reporting UI be shown on pin violations? Default value: true “security.ssl.errorReporting.url” Where should SSL error reports be sent? Default value: https://incoming. telemetry.mozilla.org/submit/sslreports/ “security.ssl.errorReporting.automatic” Should error reports be sent without user interaction. Default value: false. Note: this pref is overridden by the value of security.ssl.errorReporting.enabled This is only set when specifically requested by the user. The user can set this value (or unset it) by checking the “Automatically report errors in the future” checkbox when about:neterror is displayed for SSL Errors. 2 Chapter 1. SSL Error Reporting CHAPTER 2 Firefox This is the nascent documentation of the Firefox front-end code. Directory Links Architecture and Data Formats Directory links are enhancements to the new tab experience that combine content Firefox already knows about from user browsing with external content. There are 3 kinds of links: • directory links fill in additional tiles on the new tab page if there would have been empty tiles because the user has a clean profile or cleared history • suggested links are shown if certain triggering criteria matches the user’s browsing behavior, i.e., if the user has a top site that matches one of several possible sites. E.g., only show a sports suggestion if the user has a sport site as a top site • enhanced links replace a matching user’s visible history tile from the same site but only the visual aspects: title, image, and rollover image To power the above features, DirectoryLinksProvider module downloads, at most once per 24 hours, the directory source links as JSON with enough data for Firefox to determine what should be shown or not. This module also handles reporting back data about the tiles via asynchronous pings that don’t return data from the server. For the directory source and ping endpoints, the default preference values point to Mozilla key-pinned servers with encryption. No cookies are set by the servers and Firefox enforces this by making anonymous requests. • default directory source endpoint: https://tiles.services.mozilla.com/v3/links/ fetch/%LOCALE%/%CHANNEL% • default directory ping endpoint: https://tiles.services.mozilla.com/v3/links/ Preferences There are two main preferences that control downloading links and reporting metrics. 3 Mozilla Source Tree Docs, Release 55.0a1 browser.newtabpage.directory.source This endpoint tells Firefox where to download directory source file as a GET request. It should return JSON of the appropriate format containing the relevant links data. The value can be a data URI, e.g., an empty JSON object effectively turns off remote downloading: data:text/plain,{} The preference value will have %LOCALE% and %CHANNEL% replaced by the appropriate values for the build of Firefox, e.g., • directory source endpoint: https://tiles.services.mozilla.com/v3/links/fetch/en-US/release browser.newtabpage.directory.ping This endpoint tells Firefox where to report Tiles metrics as a POST request. The data is sent as a JSON blob. Setting it to empty effectively turns off reporting of Tiles data. A path segment will be appended to the endpoint of “view” or “click” depending on the type of ping, e.g., • view ping endpoint: https://tiles.services.mozilla.com/v3/links/view • click ping endpoint: https://tiles.services.mozilla.com/v3/links/click Data Flow When Firefox starts, it checks for a cached directory source file. If one exists, it checks for its timestamp to determine if a new file should be downloaded. If a directory source file needs to be downloaded, a GET request is made then cacheed and unpacked the JSON into the different types of links. Various checks filter out invalid links, e.g., those with http-hosted images or those that don’t fit the allowed suggestions. When a new tab page is built, DirectoryLinksProvider module provides additional link data that is combined with history link data to determine which links can be displayed or not. When a new tab page is shown, a view ping is sent with relevant tiles data. Similarly, when the user clicks on various parts of tiles (to load the page, pin, block, etc.), a click ping is sent with similar data. Both of these can trigger downloading of fresh directory source links if 24 hours have elapsed since last download. Users can turn off the ping with in-new-tab-page controls. As the new tab page is rendered, any images for tiles are downloaded if not already cached. The default servers hosting the images are Mozilla CDN that don’t use cookies: https://tiles.cdn.mozilla.net/ and Firefox enforces that the images come from mozilla.net or data URIs when using the default directory source. Source JSON Format Firefox expects links data in a JSON object with top level keys each providing an array of tile objects. The keys correspond to the different types of links: directory, suggested, and enhanced. Example Below is an example directory source file: 4 Chapter 2. Firefox Mozilla Source Tree Docs, Release 55.0a1 { "directory":[ { "bgColor":"", "directoryId": 498, "enhancedImageURI":"https://tiles.cdn.mozilla.net/images/ ,!d11ba0b3095bb19d8092cd29be9cbb9e197671ea.28088.png", "imageURI":"https://tiles.cdn.mozilla.net/images/ ,!1332a68badf11e3f7f69bf7364e79c0a7e2753bc.5316.png", "title":"Mozilla Community", "type":"affiliate", "url":"http://contribute.mozilla.org/" } ], "enhanced":[ { "bgColor":"", "directoryId": 776, "enhancedImageURI":"https://tiles.cdn.mozilla.net/images/ ,!44a14fc405cebc299ead86514dff0e3735c8cf65.10814.png", "imageURI":"https://tiles.cdn.mozilla.net/images/ ,!20e24aa2219ec7542cc8cf0fd79f0c81e16ebeac.11859.png", "title":"TurboTax", "type":"sponsored", "url":"https://turbotax.intuit.com/" } ], "suggested":[ { "adgroup_name":"open-source browser", "bgColor":"#cae1f4", "check_inadjacency": true, "directoryId": 702, "explanation":"Suggested for%1$S enthusiasts who visit sites like%2$S", "frecent_sites":[ "addons.mozilla.org", "air.mozilla.org", "blog.mozilla.org", "bugzilla.mozilla.org", "developer.mozilla.org", "etherpad.mozilla.org", "hacks.mozilla.org", "hg.mozilla.org", "mozilla.org", "planet.mozilla.org", "quality.mozilla.org", "support.mozilla.org", "treeherder.mozilla.org", "wiki.mozilla.org" ], "frequency_caps":{"daily":3,"total": 10}, "imageURI":"https://tiles.cdn.mozilla.net/images/ ,!9ee2b265678f2775de2e4bf680df600b502e6038.3875.png", "time_limits":{"start":"2014-01-01T00:00:00.000Z","end":"2014-02- ,!01T00:00:00.000Z"}, "title":"Thanks for testing!", "type":"affiliate", "url":"https://www.mozilla.com/firefox/tiles" 2.1. Directory Links Architecture and Data Formats 5 Mozilla Source Tree Docs, Release 55.0a1 } ] } Link Object Each link object has various values that Firefox uses to display a tile: • url - string url for the page to be loaded when the tile is clicked. Only https and http URLs are allowed. • title - string that appears below the tile. • type - string relationship of the link to Mozilla. Expected values: affiliate, organic, sponsored. • imageURI - string url for the tile image to show. Only https and data URIs are allowed. • enhancedImageURI - string url for the image to be shown before the user hovers. Only https and data URIs are allowed. • bgColor - string css color for additional fill background color. • directoryId - id of the tile to be used during ping reporting Suggested Link Object Extras A suggested link has additional values: • adgroup_name - string to override the hardcoded display name of the triggering set of sites in Firefox. • check_inadjacency - boolean if true prevents the suggested link from being shown if the new tab page is showing a site from an inadjacency list. • explanation - string to override the default explanation that appears below a Suggested Tile. %1$S is replaced by the triggering adgroup name and %2$S is replaced by the triggering site.

Page 1 INFOSEC UPDATE 2006 -- June 19-20, 2006 01 Introduction Category 01 Introduction 2006-06-12 Introduction M. E. Kabay, PhD, CISSP WELCOME Welcome to the 2005 edition of the Information Security Year in Review (IYIR) project. In 1993 and 1994, I was an adjunct professor in the Institute for Government Informatics Professionals in Ottawa, Canada under the aegis of the University of Ottawa. I taught a one-semester course introducting information security to government personnel and enjoyed the experience immensely. Many of the chapters of my 1996 textbook, _The NCSA Guide to Enterprise Security_ published by McGraw-Hill were field-tested by my students. In 1995, I was asked if I could run a seminar for graduates of my courses to bring them up to date on developments across the entire field of information security. Our course had twenty students and I so enjoyed it that I continued to develop the material and teach the course with the NCSA (National Computer Security Association; later called ICSA and then eventually renamed TruSecure Corporation and finally CyberTrust, its current name) all over the United States, Canada, Europe, Asia and the Caribbean. After a few years of working on this project, it became obvious that saving abstracts in a WordPerfect file was not going to cut it as an orderly method for organizing the increasing mass of information that I was encountering in my research.

  • Browser Versions Carry 10.5 Bits of Identifying Information on Average [Forthcoming Blog Post]
    Browser versions carry 10.5 bits of identifying information on average [forthcoming blog post] Technical Analysis by Peter Eckersley This is part 3 of a series of posts on user tracking on the modern web. You can also read part 1 and part 2. Whenever you visit a web page, your browser sends a "User Agent" header to the website saying what precise operating system and browser you are using. We recently ran an experiment to see to what extent this information could be used to track people (for instance, if someone deletes their browser cookies, would the User Agent, alone or in combination with some other detail, be enough to re-create their old cookie?). Our experiment to date has shown that the browser User Agent string usually carries 5-15 bits of identifying information (about 10.5 bits on average). That means that on average, only one person in about 1,500 (210.5) will have the same User Agent as you. On its own, that isn't enough to recreate cookies and track people perfectly, but in combination with another detail like an IP address, geolocation to a particular ZIP code, or having an uncommon browser plugin installed, the User Agent string becomes a real privacy problem. User Agents: An Example of Browser Characteristics Doubling As Tracking Tools When we analyse the privacy of web users, we usually focus on user accounts, cookies, and IP addresses, because those are the usual means by which a request to a web server can be associated with other requests and/or linked back to an individual human being, computer, or local network.

  • Security Analysis of Firefox Webextensions
    6.857: Computer and Network Security Due: May 16, 2018 Security Analysis of Firefox WebExtensions Srilaya Bhavaraju, Tara Smith, Benny Zhang srilayab, tsmith12, felicity Abstract With the deprecation of Legacy addons, Mozilla recently introduced the WebExtensions API for the development of Firefox browser extensions. WebExtensions was designed for cross-browser compatibility and in response to several issues in the legacy addon model. We performed a security analysis of the new WebExtensions model. The goal of this paper is to analyze how well WebExtensions responds to threats in the previous legacy model as well as identify any potential vulnerabilities in the new model. 1 Introduction Firefox release 57, otherwise known as Firefox Quantum, brings a large overhaul to the open-source web browser. Major changes with this release include the deprecation of its initial XUL/XPCOM/XBL extensions API to shift to its own WebExtensions API. This WebExtensions API is currently in use by both Google Chrome and Opera, but Firefox distinguishes itself with further restrictions and additional functionalities. Mozilla’s goals with the new extension API is to support cross-browser extension development, as well as offer greater security than the XPCOM API. Our goal in this paper is to analyze how well the WebExtensions model responds to the vulnerabilities present in legacy addons and discuss any potential vulnerabilities in the new model. We present the old security model of Firefox extensions and examine the new model by looking at the structure, permissions model, and extension review process. We then identify various threats and attacks that may occur or have occurred before moving onto recommendations.

  • Visual Validation of SSL Certificates in the Mozilla Browser Using Hash Images
    CS Senior Honors Thesis: Visual Validation of SSL Certificates in the Mozilla Browser using Hash Images Hongxian Evelyn Tay [email protected] School of Computer Science Carnegie Mellon University Advisor: Professor Adrian Perrig Electrical & Computer Engineering Engineering & Public Policy School of Computer Science Carnegie Mellon University Monday, May 03, 2004 Abstract Many internet transactions nowadays require some form of authentication from the server for security purposes. Most browsers are presented with a certificate coming from the other end of the connection, which is then validated against root certificates installed in the browser, thus establishing the server identity in a secure connection. However, an adversary can install his own root certificate in the browser and fool the client into thinking that he is connected to the correct server. Unless the client checks the certificate public key or fingerprint, he would never know if he is connected to a malicious server. These alphanumeric strings are hard to read and verify against, so most people do not take extra precautions to check. My thesis is to implement an additional process in server authentication on a browser, using human recognizable images. The process, Hash Visualization, produces unique images that are easily distinguishable and validated. Using a hash algorithm, a unique image is generated using the fingerprint of the certificate. Images are easily recognizable and the user can identify the unique image normally seen during a secure AND accurate connection. By making a visual comparison, the origin of the root certificate is known. 1. Introduction: The Problem 1.1 SSL Security The SSL (Secure Sockets Layer) Protocol has improved the state of web security in many Internet transactions, but its complexity and neglect of human factors has exposed several loopholes in security systems that use it.
