Lostalgic

This project is based on the entire ABC’s LOST TV show scripts, 115 episodes in 7 seasons, that I managed to parse from Lostpedia. I also parsed this page with additional information about hidden characters relations. My aim for this project is not (only) to visualize some properties and patterns out of the script but actually to allow to read and enjoy the series in a different way. I plan to add new views (will inform through twitter), more aimed to reveal global patterns in the script, and I will include cliffhangers and writing teams information. ...

Autenticación hardware mediante un USB

pam_usb es un módulo que permite añadir autenticación hardware utilizando unidades de almacenamiento extraíbles “normales”, como memorias USB, tarjetas SD/MMC, etc. Mediante pamusb podemos especificar que se ejecuten diversas acciones cuando reconoce el dispositivo conectado, como por ejemplo iniciar sesión sin tener que introducir la contraseña o desactivar el salvapantallas, por lo que se puede utilizar para implantar un sistema de autenticación en dos pasos (2FA). Sirve cualquier USB, ya que el módulo no modifica su contenido, sino que comprueba el UUID, el número de serie, el fabricante y el modelo, por lo que, aunque se copie, no se podrá suplantar fácilmente. ...

Major security vulnerability in some Samsung phones could trigger factory reset via web page

A major security vulnerability has been discovered in some TouchWiz-based Samsung smartphones, including the Galaxy S2 and certain Galaxy S3 models on older firmware. The bug was first demonstrated days ago by security researcher Ravi Borgaonkar at the Ekoparty security conference. It involves the use of a single line of code in a malicious web page to immediately trigger a factory reset without prompting the user, or allowing them to cancel the process. Even more serious is the possibility that this could be paired with a similar glitch to render the user’s SIM card inoperable. And as the malicious code is in URI form, it can also be delivered via NFC or QR code. ...

How To Ask Questions The Smart Way

In the world of hackers, the kind of answers you get to your technical questions depends as much on the way you ask the questions as on the difficulty of developing the answer. This guide will teach you how to ask questions in a way more likely to get you a satisfactory answer. Now that use of open source has become widespread, you can often get as good answers from other, more experienced users as from hackers. This is a Good Thing; users tend to be just a little bit more tolerant of the kind of failures newbies often have. Still, treating experienced users like hackers in the ways we recommend here will generally be the most effective way to get useful answers out of them, too. ...

Monitorizar el tamaño de un directorio con monit

monit es un herramienta para monitorizar procesos, ficheros, directorios y sistemas de ficheros, que permite enviar alertas cuando suceden eventos tales como que un proceso no arranca, se incrementa la carga del sistema o el uso de memoria por encima de un umbral determinado, se modifican ficheros o directorios, etc. El problema es que, por ahora, no permite controlar que el tamaño de un directorio, es decir, de los ficheros contenidos en él, supere cierto valor. Sin embargo, podemos conseguir este resultado utilizando un script que se ejecute de forma periódica y que modifique la fecha de un fichero concreto mientras el tamaño del directorio sea correcto. Este fichero de control nos servirá para saber cuándo se ha superado el limite. ...

Comprobar que no tenemos configurado Apache como un proxy abierto

Revistando logs de Apache, he visto que tenía algunas entradas del tipo: 93.174.93.52 - - [18/Sep/2012:02:23:11 +0200] "GET http://myproxylists.com/my-http-headers HTTP/1.1" 404 1046 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.28) Gecko/20120306 Firefox/3.6.28 (.NET CLR 3.5.30729)" 93.174.93.52 - - [20/Sep/2012:08:21:08 +0200] "GET http://myproxylists.com/my-http-headers HTTP/1.1" 404 1046 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.28) Gecko/20120306 Firefox/3.6.28 (.NET CLR 3.5.30729)" Este suele ser el resultado de peticiones maliciosas que buscan encontrar servidores proxy abiertos. Si encontramos entradas de este tipo, lo primero que deberíamos hacer es comprobar que tenemos configurado el servidor correctamente, para no permitir hacer de proxy a peticiones de anónimos. De hecho, si no necesitamos un servidor proxy, lo mejor es asegurarnos que la directiva ProxyRequests no está inicializada a on. ...

I am a ”pentester” who has performed simulated attacks that confirm your worst nightmares about power-grid blackouts and financial meltdowns. ...
