5 5 2 CHANGELOG Version: 4.0 Modules Code Review Optimize Source Code of different modules Modules Update Optimize all modules to support latest version of all browsers. Module Module Module New Information Gathering Module Replacement / New Module (Iframe / Framebuster) New Feature / Anti- Debugging Each module can be extended by an information gathering module. This module will collect information from target PC (e.g. OS, Language, Timezone, IP-Address etc.) The existing IFRAME module was replaced by a new module. In previous releases the FFWeb code could be rejected by some webpages, to prevent the content can be shown in an IFRAME. The new module require php preinstalled on the webserver. The new version will bypass IFRAME Framebustering technique. A special encoder script was written, to prevent an easy debugging / interception of javascript code. Module New Module (IE Click Once) A new module was added. It runs only in an Internet Explorer browser. A click once application will be loaded. User has to accept the application only once. Code signing with a trusted certificate is integrated. GUI Update New enhanced content check was integrated, which detects if all necessary files will be successfully written. Mobile Targets Update All modules were tested and optimized for mobile targets.

9 9 Version: 2.1 FinFly Lan Module Support Introduced support for the Infection proxy in all modules, specifically the modules which make use of Iframes and in the past would fail to load inside the infection proxy. New routines were added to the following modules: XPI-Popup XPI-Plugin Bar IFrame Java Module Bugfix / XPI Modules This version fixes a bug where the page wouldn t load if one of the XPI modules (xpi_popup and xpi_bar) is loaded in a different web browser than Firefox or Seamonkey. Both modules will now load the Iframe only and will not run any code that involves the actual XPI loading and executing. This affected not only Internet Explorer, the fix Module Improvement / XPI Modules Module Improvement / XPI Modules Module Bugfix / Improvement XPI- Modules supports all general available web browsers. The web browser Seamonkey (that is derived from Mozilla Firefox) is now supported in the XPI modules (XPI Popup and XPI Plugin-Bar). Handling of the payload was changed. These modules don t rely on a cookie and can detect if the XPI is actually installed or not, now. This fix patch two issues of the past release: The page now loads after the installation of the XPI, but does not attempt to install the XPI again - no popup is shown. After a de-installation of the XPI the module allows new attempts to install the XPI again. The popup image for all relevant modules is now un-selectable. Module Bugfix / XPI Popup The XPI - Popup module supports newlines now. Module Bugfix / XPI Plugin Bar Modified the click-coordinates of the XPI Plugin Bar module to make it run properly. GUI Improvement / Bugfix Modified Output Folder and FinFly Lan Settings can be configured.

14 14 3 LIMITATIONS This chapter covers current known limitations within the FinFly Web Software. Feature FinFly Web FinFly Web Configuration Script Blocker Iframe / Popup Prevention All Modules Latest Browser Support Limited Start Options Description Full Anti-Virus / Anti-Spyware bypassing cannot be guaranteed due to regular changes in these products Each update must replace the previous configuration file of FinFly Web, otherwise some new features were not supported. All previous settings will be gone. When a script-blocker is installed and configured to block all sorts of scripts from public websites the generated attack code will not work. Some Websites prevent to be loaded in an iframe (e.g. youtube, google/gmail, facebook) and cannot be bypassed with frame buster technology. Encoding, Obfuscating and Anti-Debugging technology, which can be combined with each module, can prevent it to be executed. In this case the options have to be disabled and the module has to be used plain. Based on the update and development circle of FFWeb, there is no guarantee, that always the latest browser version can be supported by each module. Each FinFly Web modules, especially Static & Iframe are limited by the functionality of the Browser. Following different download and execute possibilities are available: - Run: Browser will download and start the payload within one step - Download: Browser will download the payload. User has to open the downloaded payload manually. - Extra Warning: e.g. IE/Chrome will show an extra warning to the target, if a file will be requested, which could harm the system. On Windows target systems it

15 15 will triggered by: o o File-Extension: each *.exe file will trigger that warning Unsigned Executable: if the *.exe file is not signed by a trusted root CA, another warning will be shown. Signed Java Applet IE Click Once Web server Support Payload want be started automatically Browser Cache / Cleanup The latest Java version blocks any un-/self-signed Java applet by default. Please sign the applet with a certificate from a trusted root CA. The module is limited to Internet Explorer and Windows target systems. The module needs an executable/payload, which is signed with a code signing certificate from a trusted root CA. Currently only Apache web server, which hosted the FinFly Web output, is tested and supported. The web server needs to have PHP and CGI support; otherwise IFRAME and Information Gathering module cannot be used. A setup guide how to get PHG & CGI support for an Apache web server can be found in the training slides and user manual. Most of the browsers only allow saving the content. FinFly Web can only trigger an automatic start/run of the payload via the Java Applet module. With all other modules the targets needs to run the delivered payload manually. Payload of a Linux Targets won t have an executable permission by default and cannot be started automatically. Some operation seem to run only once or always on a target system. The reason can be: - Once: FinFly Web creates a cookie on the target system, which prevents multiple starts against one single target. The cookie will be stored on the target system, as soon as the payload is requested by the target. If the infection will fail, a new/different payload has to be generated and provided to the target on a different web server address.

16 16 - Always: if the target will clean up his browser/cookie cache every time, when the browser will be closed, FinFly Web (standalone version) cannot identify, if the payload was provided and installed on the target system or not. Solution: use FinFly LAN/NET/ISP in combination with FinFly Web. Missing Plug-in / Browser Sandbox / Missing Permission ios Payload Not every module can be used against each target. Some browsers are not available for each platform (e.g. Internet Explorer). Java Applets cannot be started on Mobile Targets (no Java Runtime Environment available or pre-installed by default). Especially on Mobile Targets payload runs with limited user permission or inside a sandbox. Currently only *.app files are supported, which are not compatible with the FinSpy Trojan.
