Sistema binario: unos y ceros a través de la historia

Los unos y los ceros llevan milenios entre nosotros, desde algunas culturas primitivas, pero las bombillas se han ido encendiendo poco a poco hasta llegar a su actual omnipresencia en la electrónica. Primero fueron Leibniz y la aritmética, luego Boole y la lógica, y finalmente Shannon y su idea de utilizar el álgebra de Boole para simplificar los circuitos. Una historia apasionante hasta llegar a nuestro smartphone. » David G. Ortiz | blogthinkbig.com

Érase una vez unos ’hackers’ hispanos...

Vivimos en una era de ’ciberguerras’, intrusiones en línea e inseguridad informática, pero también en una época de libertad de acceso a cantidades ingentes de datos e información sin precedentes, de acceso casi ilimitado al conocimiento. No es posible explicar semejante paradoja sin asomarse la historia del ’hacking’ y, aunque parezca mentira, en España esa historia es apasionante. » hackstory.es » Pablo Romero | elmundo.es

Open letter to the Linux World

So, what is systemd? Well, meet your new God. You may have been praying at the alter of simplicity, but your religion is being deprecated. It likely already happened without your knowledge during an upgrade of your Linux box. systemd is the all knowing, all controlling meta-deity that sees all and supervises all. It’s the new One Master Process that aspires to control everything it can - and it’s already doing a lot. It’s what init would look like if it were a transformer on steroids. It’s complicated, multi-faceted, opaque, and supremely powerful. ...

Offline attack shows Wi-Fi routers still vulnerable

The attack exploits weak randomization, or the lack of randomization, in a key used to authenticate hardware PINs on some implementations of Wi-Fi Protected Setup, allowing anyone to quickly collect enough information to guess the PIN using offline calculations. By calculating the correct PIN, rather than attempting to brute-force guess the numerical password, the new attack circumvents defenses instituted by companies. » Offline bruteforce attack on WiFi Protected Setup » Hands-on: hacking WiFi Protected Setup with Reaver< /a> ...

Hackers transform a smartphone gyroscope into an always-on microphone

Apps that use your smartphone’s microphone need to ask permission, but the motion sensors? No say-so needed. That might not sound like a big deal, but security researchers from Stanford University and defense firm Rafael have discovered a way to turn Android phone gyroscopes into crude microphones. They call their app ”Gyrophone” and here’s how it works: the tiny gyros in your phone that measure orientation do so using vibrating pressure plates. As it turns out, they can also pick up air vibrations from sounds, and many Android devices can do it in the 80 to 250 hertz range – exactly the frequency of a human voice. ...

Reflections on Trusting Trust

You can’t trust code that you did not totally create yourself. (Especially code from companies that employ people like me.) No amount of source-level verification or scrutiny will protect you from using untrusted code. In demonstrating the possibility of this kind of attack, I picked on the C compiler. I could have picked on any program-handling program such as an assembler, a loader, or even hardware microcode. As the level of program gets lower, these bugs will be harder and harder to detect. A well installed microcode bug will be almost impossible to detect. ...

The VP of Devil’s Advocacy

The tenth man. If nine of us look at the same information and arrive at the exact same conclusion, it’s the duty of the tenth man to disagree. No matter how improbable it may seem, the tenth man has to start thinking with the assumption that the other nine are wrong. » MG Siegler | techcrunch.com

Why the Security of USB Is Fundamentally Broken

That’s the takeaway from findings security researchers Karsten Nohl and Jakob Lell plan to present next week, demonstrating a collection of proof-of-concept malicious software that highlights how the security of USB devices has long been fundamentally broken. The malware they created, called BadUSB, can be installed on a USB device to completely take over a PC, invisibly alter files installed from the memory stick, or even redirect the user’s internet traffic. Because BadUSB resides not in the flash memory storage of USB devices, but in the firmware that controls their basic functions, the attack code can remain hidden long after the contents of the device’s memory would appear to the average user to be deleted. And the two researchers say there’s no easy fix: The kind of compromise they’re demonstrating is nearly impossible to counter without banning the sharing of USB devices or filling your port with superglue. ...
