El cerebro es un órgano fascinante y relativamente desconocido para la ciencia (y para muchos que tienen uno y lo usan poco, pero eso es otra historia) y es capaz de cosas realmente increíbles, como por ejemplo ser consciente de si mismo, pero sin embargo también tiene un buen número de defectos que permite engañarlo de una manera relativamente fácil. Las desarrolladoras lo saben y muchas de ellas se aprovechan de ellas, pervirtiendo un modelo como el free-to-play que podría tener enormes virtudes y convirtiéndolo en una máquina sacacuartos del Lado Oscuro. ...

You don’t often see clever builds like this Technic Dot Matrix Display by AncientJames from New Zealand. As the reel starts rolling, the patterns on the cards inside correspond with the patterns on the display and can show anything that fits into a 5x5 square. The creator’s video is titled, “Everything is awesome”. Well, this build certainly is! » Gergo Vas | kotaku.com

The pursuit of lock-picking is as old as the lock, which is itself as old as civilization. But in the entire history of the world, there was only one brief moment, lasting about 70 years, where you could put something under lock and key—a chest, a safe, your home—and have complete, unwavering certainty that no intruder could get to it. This is a feeling that security experts call “perfect security.” Since we lost perfect security in the 1850s, it has remained elusive. Despite tremendous leaps forward in security technology, we have never been able to get perfect security back. ...

El 19 de abril de 1965, Gordon Earle Moore publicaba una editorial en la revista Electronics que cambió el cómo entendíamos la tecnología. En ella aseguraba que la complejidad de los circuitos integrados se duplicaría cada año (luego se modificó para fijar el periodo de dos años), a la vez que los precios y costes de fabricación se verían reducidos. Cincuenta años después conocemos esta afirmación como la Ley de Moore, un exponente de la tecnología que se ha ido cumpliendo generación tras generación, pero con muchas dudas al respecto. ...

Ten years ago this week, the Linux kernel community faced a daunting challenge: They could no longer use their revision control system BitKeeper and no other Software Configuration Management (SCMs) met their needs for a distributed system. Linus Torvalds, the creator of Linux, took the challenge into his own hands and disappeared over the weekend to emerge the following week with Git. Today Git is used for thousands of projects and has ushered in a new level of social coding among programmers. ...

Pero nada, oye, les da igual. Da igual que las webs de descargas, con la ley en la mano, no sean ilegales. Da igual que ningún juez en España (ninguno, ¿eh? que se dice pronto) haya cerrado nunca una web de descargas. Da igual que las pocas que han cerrado lo hayan hecho motu proprio por miedo o por acorralamiento. Da igual que gran parte de las querellas contra webs de descargas ni siquiera hayan llegado a juicio, sino que los jueces hayan sobreseído los casos al ver evidente la ausencia de delito. Todo eso les da igual. ...

Security researchers at Ben Gurion University in Israel have found a way to retrieve data from an air-gapped computer using only heat emissions and a computer’s built-in thermal sensors. The method would allow attackers to surreptitiously siphon passwords or security keys from a protected system and transmit the data to an internet-connected system that’s in close proximity and that the attackers control. They could also use the internet-connected system to send malicious commands to the air-gapped system using the same heat and sensor technique. The proof-of-concept attack requires both systems to first be compromised with malware. And currently, the attack allows for just eight bits of data to be reliably transmitted over an hour—a rate that is sufficient for an attacker to transmit brief commands or siphon a password or secret key but not large amounts of data. It also works only if the air-gapped system is within 40 centimeters (about 15 inches) from the other computer the attackers control. But the researchers, at Ben Gurion’s Cyber Security Labs, note that this latter scenario is not uncommon, because air-gapped systems often sit on desktops alongside Internet-connected ones so that workers can easily access both. ...

Mediante Latch, podemos añadir una capa extra de seguridad a nuestro servicio SSH, limitando la ventana de tiempo durante la cual permitimos iniciar sesión en el servidor. Instalación Descargamos los paquetes que vamos a necesitar: $ sudo aptitude install gcc make $ sudo aptitude install libpam0g-dev libcurl4-gnutls-dev libssl-dev (Si ya teníamos instalado el paquete libcurl4-openssl-dev, podemos usar éste en lugar de libcurl4-gnutls-dev.) Descargamos el código de github y compilamos: $ git clone https://github.com/ElevenPaths/latch-plugin-unix.git $ cd latch-plugin-unix $ ./configure prefix=/usr sysconfdir=/etc && make && sudo make install Antes de continuar, vamos al área de desarrolladores y creamos una cuenta para este servicio. Ahí obtenemos el identificador de aplicación y la contraseña. ...

some tracking methods do attempt to track the user over a long time, and in particular attempt to make it difficult to evade the tracking. This is sometimes done for advertisement purposes, but can also be done to stop certain attacks like brute forcing or to identify attackers that return to a site. In its worst case, from a private perspective, the tracking is done to follow a user across various web sites. Over the years, browsers and plugins have provided a number of ways to restrict this tracking. Here are some of the more common techniques how tracking is done and how the user can prevent (some of) it ...
