How we phished a 20 billion Euro company out of 79% of their passwords

This article originally appeared on, and was featured by Medium, and the Belgian technology publication Data News. Disclaimer: We were asked to do this, encrypted (and salted) the sensitive data, never saw, had or stored any non-encrypted sensitive data, and we had some inside help. We loudly applaud this initiative from this company, security, like punctuation and proper grammar, matters. A leading player in its industry, with a turn-over of an impressive 20 billion Euro annually, asked us to do something special for their IT operations management/InfoSec meetup in Hannover, Germany. Information security, sometimes shortened to InfoSec, is the »

Arduino + NodeJS = Theremin w/ Visualizer

Here at Cloudoki we came up with an idea for our #hackfridays: to make an theremin ♪♫ with an Arduino! So here's how we did it. Arduino Theremin We looked inside our Arduino kit for a while and decided to use an LDR sensor and a piezo to create our theremin. Requirements: Arduino LDR Piezo Resistor Arduino IDE The Circuit So we setup our theremin following the Fritzing circuit above, resulting on the image bellow. Outside #hackfridays ftw The code: int val = 0; const int piezoPin = 6; void setup() { pinMode(piezoPin, OUTPUT); delay(3000); } void loop() { digitalWrite(piezoPin, HIGH); delayMicroseconds(val) »

Internet of Things - make Raspberry PI interact with Slack

About IoT One of the most exciting applications of technology is the possibility of connecting a vast array of devices, assign them unique alias ( like us humans having names ) and allow them to be individuals in a “Machinapolis”, a society of devices. They can talk to each other, ask for things from each other and report stuff back to us human overlords. Thanks to the Internet, communication between each one of these device is made easy. Imagine that you have a fridge capable of scanning its content, learn exactly what products you like to have and in what quantity, and »

#HackFridays - The gist

Here at cloudoki we strongly believe in the added value that comes from giving everybody the tools and means to release their creativity and curiosity, while learning from it. Hacking your way through some idea is a perfect way to pick your brain, in a fast paced chaotic and fun environment. For these reasons, and much more, the Cloudoki team gets together every Friday and rejoices with it's own HackFriday. Project ideas Hack projects can take many shapes and forms, really. Our M.O. regarding ideas is as simple as having a running poll of ideas where anyone, anytime and »

Going native with React Native

During a few HackFridays we've experimented with React Native by building a voting app. MuchVote, SuchRate by Donderlab (Source Code, Website, App Store, Google Play) Here it is our take on React Native. What is React Native Instead of trying to accomplish the impossible "write once, run anywhere", React Native's promise is that you "Learn once, write anywhere", you can use the experience you have building great user interfaces from the web to mobile. But you will still need different code bases for each platform. You may have components that can be reused directly and others that are platform specific. »
