VOORSTEL: CRYPTO STANDAARDEN WEGHALEN BIJ NSA-NIST!

OMERTA INFORMATION SECURITY – Rotterdam 27 Mei 2014

house-committee-initiates-nist-nsa-separation-on-crypto-standards

Goed nieuws, toch? Het scheiden van de de NSA met betrekking tot de cryptostandaarden in samenwerking met NIST

Er zal uiteraard bij het toetsen en toewijzen van standaarden voor dit soort zaken wel gebruikt worden gemaakt van de kennis die de NSA over Crypto heeft.

Laten we dus niet te vroeg juichen, maar in ieder geval is er een begin gemaakt! wordt vervolgd….

Hacking Cable TV Networks to Broadcast Your Own Video Channel

 

hacking cable TV network
I was watching my favorite show on the television and it was just half over when I saw something which was definitely not a part of the show I was watching. My television screen gone blank for a couple of seconds and then what I saw was totally unbelievable for my eyes.
It was my friend ‘Rahul Sasi’ on the television and I was still wondering that how did he interrupted in between a television show like happens in Sci-Fi movies, someone hijacks television or computer to deliver some kind of message or warning. Also like in some horror movies in which sometime ghostly images interrupts between the television and suddenly comes out. Oh my god!
But, nothing happened like that in my case, my friend didn’t came out. Just few minutes later I was again redirected to the same show I was watching, only a part of it I missed, but never mind I’ll watch it on the YouTube later.

Onion Pi: NSA Proof TOR PROXY?

OMERTA INFORMAATION SECURITY – Rotterdam 27 Mei 2014

 

Op raspberrypi.org vonden wij deze geweldige oplossing om jezelf NSA proof te maken :

 

Our good friends at Adafruit have been working on a Tor proxy box based around a Pi, which directs your internet traffic through the Tor routing service. Every network packet you send is encrypted and decrypted multiple times, and each time this happens the packet is sent through a number of relays (like onion skins: Tor stands for The Onion Router), picked at random from the thousands that make up the Tor network, before reaching its intended destination. This makes it very hard for anyone to analyse your data to find out who you are, or where you are.

Tor routing is for anyone interested in confidentiality, internet freedom and privacy. It’s of enormous use for those who need to work on confidential business, or for those in places where internet traffic is monitored by governments or other bodies. It’s used to search for forbidden material like birth control, dissenting political voices or religious debate in places where a country is behind a firewall and traffic is strictly controlled (there are many users in mainland China); in the western world it’s used by many to protect personal data from marketers, and by those who worry their data is being snooped on. Activists and whistleblowers, for whom anonymity is important, use Tor. A healthy paranoia about your internet traffic is a good thing: just because you’ve got nothing to hide doesn’t mean that you’ve got nothing to fear. I would hate to be labelled a terrorist just because I express an interest in pressure cookers and book a lot of aeroplane tickets.

You can, of course, run a Tor proxy on any machine, but the particularly nice thing about Adafruit’s Onion Pi is its portability. This means that you’re not restricted to using it in one place; you can set it up in front of the router (it behaves as a WiFi hotspot) in the office you’re working from, in your hotel room or at your Mum’s house, connect to it from your phone or computer, and your IP address will be anonymised.

Be aware that using Tor will slow your browsing down (the packets of data are travelling by a longer and less direct route than you’re used to), and that it’s not a total guarantee of anonymity.

Adafruit have made a very easy to follow tutorial on making your own Onion Pi. You may well have all the parts you need (the only piece of kit I don’t already have kicking around the house is a WiFi adapter) at home; if you don’t, you can buy a box with everything you’ll need in it from them. A portion of every sale goes to the Tor Foundation.

NIEUWE APP LAAT ZIEN HOEVEEL FACEBOOK VAN JE WEET! en ja het is veel……….

OMERTA INFORMATION SECURITY – Rotterdam 27 Mei 2014

 

Digital shadow is de nieuwe app die je inzicht kan geven in hoeveel informatie je deelt met Facebook. Dit bericht stond oorspronkelijk op searchenginejournal.com

 

A new web app that’s being described as “unnerving” and “disturbingly accurate” was launched last week, which provides an eye-opening look into how much Facebook really knows about you.

The new app, called Digital Shadow, was launched as a promotional tool for the upcoming video game Watch Dogs. It uses data you’ve given to Facebook to guess your location, your income, and your passwords.

In addition, the app also looks through your connections to find your “obsessions”, “stalkers”, and “liabilities”. People you interact with more than they interact with you are considered “obsessions”, people who interact with you more than you do with them are considered “stalkers”, and people who tag you a lot are considered “liabilities” because they spread your personal information more widely.

Some of the team here at SEJ tested out this app, and we all agree that the accuracy of the assessments are quite startling. Here is a snapshot from Managing Editor Kelsey Jones’ results, to give you an idea of how much the app can learn about your personality just from the information you’ve made publicly available on Facebook.

To use Digital Shadow and see how much Facebook know about you, just go here and click the Log in with Facebook button. The app will then comb through your Facebook page and return its findings.

PRIVACY KAN JE ALLEEN VERLIEZEN!

OMERTA INFORMATION SECURITY – Rotterdam 20 Mei 2014

Bof.nl over de avond die het BOF organiseerde met De Correspondent. Een GODWIN lezing. EEN WAT??!! Ja je leest het goed een GODWIN lezing.

Als je je privacy lief bent is dit een must read!!! Wij vinden het een van de beste stukken tot nu toe. Lees het helemaal uit, neem even de tijd en probeer het tot je door te laten dringen.

Als je dan toch lekker bezig bent met lezen en je maakt je zorgen over waarom dit allemaal gebeurd kan je ook nog even dit stukje film bekijken. Het één heeft niet direct iets met het andere te maken, maar als je goed nadenkt zijn er veel verbanden. Registreren en controleren zorgen voor veel gevaren. En vaak bent u de dupe!

GEBRUIK JE CAMERA VOOR QUANTUM CRYPTOGRAFIE ( random number generator)

OMERTA INFORMATION SECURITY – Rotterdam 20 Mei

Zwitserse wetenschappers zijn erin geslaagd om je camera te gebruiken als Truly random number generator.

Tot nu toe was het erg moeilijk voor computers om truly random number generators te maken.  ( dus echt een willekeurig gegenereerd nummer, verzonnen en niet terug te halen ) Een computer is namelijk een apparaat dat alleen door input te geven, output kan genereren. Er zit dus niets randoms in. ( theoretisch wel iets, maar dat is een andere discussie )

Het random genereren van deze nummers gebeurd met licht :

Het werkt zo :

Each pixel senses the number of photons that arrive in a certain period of time. These photons are converted into electrons, which are then amplified by a factor determined by the camera’s sensitivity setting (ISO setting). It’s straightforward to calculate the average number of electrons this process should produce, given the probabilistic nature of photon emission. But the actual number of electrons should differ by a number that is random. That produces a single random digit. And since a light-sensitive array consists of many pixels working in parallel, it is possible to generate a large quantity of random digits from each image.
