Web and Intranet Security

The World Wide Web is full of confidential stuff. It doesn´t matter what kind you are looking for. Full confidential Datasheet´s from manufacturers, customer data from Tax office´s, Burger King internal payroll´s.  IF you want them just search for it you will find it.

Iám doing random forensic to keep me up 2 date.. Mostly the company´s staff is lazy or stupid to keep the internal protected. Also privat people don´t care about the privacy or doesn´t now how to handle a NAS to keep details away from the public.

Ok… Never touch anything you find on the net or change it! But here iám a Asshole and set his Alarm clock to 3:30am  ….  just a prank… but never do anything else like destroy printer or use fax that not belongs to you!

 

 

 

It take´s only less than 10 minutes to find a  Jpeg in good quality with valid ID-Card´s.  Less than 1 minute to find a privat NAS Service included nude pictures. 1 silly minute for confidential PDF´s that are under NDA. Very high confidential Key´s for RSA or other technical stuff like HDCP.

 

Do not change or touch anything if you find stuff like that. It´s a local Power supply!

My 50 Cent: “ Admin´s please read a book like internet for dummies….“

34 years of Copy Protection – DRM – and the waste of money

Should we say 34 years of piracy?

In 2018 we got the 35th birthday of Copy Protection, now called as DRM. In the early 80th developer of bigger Company´s like Lucas Art´s started to protect their games with a kind of Copy Protection with different methodes.  On Floppy Disc´s they started to make extra Bad Sectors to fight piracy, the other way was to prevent to copy a Code Book that was printed in colors so nobody can copy the book on a copying machine cause they work only in black and white.

Every of those Copy Protection´s was cracked few weeks lator or they found a way to bypass it.

O2 Box 6431 Bootloader – WTF

Hi, so my DSL line is based on O2. Since i got this account i had a issue with VOIP services. So if you wanner call somebody you can´t reach any phone number it gives the busy tone and nothing happens. So today O2 Support called me and we tried to figure out what´s wrong with this device.

OTP Security Part II

 

To verife the decrypted CW, we can use the offline CSA decrypter and have a look arround.

Importen is that we record the full raw TS file from the beam. (included ECM/EMM data)

Tools we need!

  • CI+ Modul for the vendor (Irdeto, Nagra,NDS,Cryptoworks,Conax)

How works the illegal IPTV and reselling?

The ditribution of illegal IPTV is very easy, but it´s not easy to take them down. Why?

The illegal IPTV sector is splitted up to a handfull of people, that reshare the content over a huge spider network to the customer. Not only IPTV STREAMS are a problem that filthy guys have a libary of illegal copys of movies that are uploaded daily to the servers.

They try to copy a IPTV imperium like Amazon and Netflix that are legal and pretty cheap to have. So why people spend money to support pirates or even terrorits networks?

Secure your code on a AVR / PIC

The good old Pic´s and Avr are mostly used in hobby projects , but sometimes also in the industrial area. Most of the chip´s dont have a security function, and you can grab all data or you can change it.

If you don´t want the somebody is modify your code there is a dirty trick to get people mad.

photo_2016-05-29_23-11-25Same for AVR´s

 

photo_2016-05-29_23-11-45After finishing you got no more an EEPROM… you got a PROM!

Thanks to the Guru 🙂

DVB encryption with OTP is weak

PREVIEW!!

Building barricades to protect content in the DVB are is not a new thing. It start´s with the used CAS and DRM Restrictions up to hardware pairing to a special vendors box. The first hardware pairing was used with the CAS Betacrypt with the BlueCam. (The BlueCam was an internal CA system that has the option to get paired to the Dbox 1) So to get a system married to a special box isn´t the big finger. The Boxkey system was also used too. It was broken very fast cause the Key itself was stored in a EEPROM inside the STB.

Today it looks like the same security, the only news is that the Key is now stored inside the DVB Core in a special protected OTP area. ST and Broadcom uses this on the newer generation of DVB chipset´s.

output_BJia82

 

 

What we need to know is:

  • Pairing uses a Diffie Hellmann handshake – special for CI+ with 3 RSA cert´s
  • The overcrypt traffic is protected by 3DES or AES (depends on the Vendor)
  • The OTP is ONE TIME PROGRAMMABLE logic
  • The smart card encrypt the Control Word (AES/3DES)

We have a weakness inside the STB file system. (Plain RSA cert´s). The next stept is we can decrypt the traffic between CI+ HOST and CLIENT. So that makes CI+ nut´s cause it is possible to emulate.

Same on the normal non CI+ version. We can do the man in the middle Attack.

PANIC! But the CW is still encrypted by a heavy encryption system. Is that true?

Maybe it is true?! xD .  AES is not broken yet, AES has too much possible Keys that we need to brut force. A Rainbow Table is not useful. 1.1 x 10^77 possible keys on 256 bit that we need to precalculate and have the storage for it. Sounds like petabyte not gigabyte.

But what happens if we can cut the possible keys to 1/2 ? or 1/4?

How? We know the CW is like 2^64 thats arround 18,4 trillion possible control words.

Back to AES… AES is a block cipher.. that means every block has the same size. Thats the differents to a stream cipher. A stream cipher is used in WEP encryption or in RC4. the stream cipher is weak, cause we can find the 3 keys that we need to decrypt the magic. For example the old PDF encryption had a stream cipher with 56 bit. The Key collision to find the magic was pretty fast cracked. Same on 128 bit version by magic Rainbow Tables.

So where the hell is the weakness? CI+ again!

A hint for all those haxxors… i stick 00000000 in and become 128 bit out..?! 128Bit / Known Plaintext= Key .. do it a couple times… and the possible key´s will be reduced!

If „CW“ known compare to reduce more keys!

Password forensic | no password is secure

Everybody looses a password in his life. Well poop is you do, but i checked the best tools to recover multiple files that was password protected. ….. and yes my own files!

Most passwords in files used in PDF,ZIP,7Zip,Office and some more

I get some PDF and ZIP in the old standard encryption on test.

PDF: 128 bit RC4

ZIP:  2.0

Any way before we talk to much. Passware was given me a 1 month serial for the Forensic Studio to test it.  Here a nice screenshot …

passware2

My aim was to get the best tool that supports speed. So the TOP TEN of Recovery tools are

  1. Passware Forensic Studio  ~ arround 1000 $ but it has 5 clients included. Extra clients arround 100$ per client.
  2. Elcomsoft provides lots of tools we choose the Bundle included 20 clients. Price arround 5000€ !!!

So we can save cash if we wanna buy a recovery tool. Passware 1000$ + 20 clients = 3000$

So the rest of the tools comes later, first i have to explain a recovery. Don´t waste your money.

The Password

If you set a password under 6 chars it can be recovered in minutes. So for all that are sure you used just 6 chars grab some FREEWARE!

The Algo how the password is secure is needed as information. If you have a password like 12345 and hash the password with MD5 it takes a little bit longer to recover it. With a SHA-512 it takes f*ck*ng long time, you can be lucky if you can recover it with good GPU´s.

So next step is what kind of encryption is applied too?! If we talk about DES it doesnt matter, but if  AES comes into the game it is a huge differents.

For example we mix SHA512 and AES256 together its a GAME OVER for now. But outside are some weaker mixes.

You are not lost if you want to take a peek in your file, that’s why i tested some tools 🙂

Anyway…. a crypto is just math and can be recovered, but it needs more time. The solution called cluster or cloud cracking it isn’t new. You can also rent EC2 Amazon to crack things.

This setup is a hell-raiser….

Master Server: 2X Intel 16 Cores – 256GB RAM – 4X Nvidia or ATI GFX card´s. The price is arround 8000€ included HDD and stuff.

Clients: just more cores as possible… and a quad SLI Nvidia… the Ram doesnt matter.. 8-16GB.

Open the HELL DOORS use EC2 with 150 Cores and a bunch of GPU power! Ohhh the price isn’t cheap… try to get some 20-30K $ together 🙂

So don’t invest much money into a recovery tool… if you need it ok spend max. 20€/$ for it. The rest can be done by Freeware!

Continue the TOP TEN: 3. low budget application´s and 4. FREEWARE

Facts on my Rig´s local just low budget….. In 1 hour i checked 62 trillions of password´s with a brute force attack.
