2 CHANGELOG

Version: 4.0 Component Change Description

Modules Code Review Optimize Source Code of different modules

Modules Update Optimize all modules to support latest version of all browsers.

Module New Information Gathering Module

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.)

Module Replacement / New Module (Iframe / Framebuster)

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 pre-installed on the webserver. The new version will bypass IFRAME Framebustering technique.

Module New Feature / Anti-Debugging

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.

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 supports all general available web browsers.

Module Improvement / XPI – Modules

The web browser Seamonkey (that is derived from Mozilla Firefox) is now supported in the XPI modules (XPI Popup and XPI Plugin-Bar).

Module Improvement / XPI – Modules

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.

Module Bugfix / Improvement XPI-Modules

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.

3 LIMITATIONS This chapter covers current known limitations within the FinFly Web Software.

Feature Description

FinFly Web Full Anti-Virus / Anti-Spyware bypassing cannot be guaranteed

due to regular changes in these products

FinFly Web Configuration Each update must replace the previous configuration file of

FinFly Web, otherwise some new features were not supported.

All previous settings will be gone.

Script Blocker When a script-blocker is installed and configured to block all

sorts of scripts from public websites the generated attack code

will not work.

Iframe / Popup Prevention Some Websites prevent to be loaded in an iframe (e.g. youtube,

google/gmail, facebook) and cannot be bypassed with frame

buster technology.

All Modules 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.

Latest Browser Support 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.

Limited Start Options 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

will triggered by:

o File-Extension: each *.exe file will trigger that

warning

o Unsigned Executable: if the *.exe file is not

signed by a trusted root CA, another warning

will be shown.

Signed Java Applet 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.

IE Click Once 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.

Web server Support 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.

Payload want be started

automatically

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.

Browser Cache / Cleanup 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.


FINUSB SUITE

SPECIFICATIONS

- 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 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).

Sandbox / Missing Permission Especially on Mobile Targets payload runs with limited user

permission or inside a sandbox.

iOS Payload Currently only *.app files are supported, which are not

compatible with the FinSpy Trojan.
