How to prevent someone from accessing your Gmail account

How to prevent someone from accessing your Gmail account

Gmail has become over the years into a very strong alternative to e-mail service Hotmail (now converted into Outlook.com) and Yahoo Mail. Google has worked to create a flexible and accessible tool that has managed to convince users. One of the biggest pushes to receive this service has come at the hands of Android, the mobile operating system company. Because this system is structured on a Google account (and therefore the Gmail mail), the company has managed to make this service more popular in the market, with over 425 million users. The problem of this success is that cibercrminales see this service as an increasingly attractive target. We tell you how to add a new layer of protection to your Gmail account so that nobody can access it.

In recent months we have witnessed as network drive on the massive amounts of data access accounts from different Internet services that have been leaked. The problem is that users often use the same password to access different accounts and this increases the risk of breaching the Gmail account. To avoid unwanted incursions, Google offers the option of establishing a second security barrier after entering the regular password. This is the verification in two steps.

Verificación en dos pasos de Gmail

To use, you must have a mobile phone. It can be done by sending codes via SMS or through an application for Android, BlackBerry and iPhone called Google Authenticator. First, you must enable the possibility of codes over the phone.

To start using this security tool, go to Gmail settings (tightening nut on the top right corner) and then "Options." We choose the tab "Accounts and Import" and then you click on "Other Settings Google's account. "

In this step, choose "Security" from the options offered to us on the left of the screen. The central feature belongs to the "Checking in two steps." Default, its status is "off." We click on the option "Edit". In the next step we click on "Start Configuration". We introduce our mobile number and choose the option of sending an SMS or voice message. We press on "Send password" and then write the six numbers that we received on the mobile. We again click on "Check" and then we choose whether we want to establish the computer as reliable (this will not have to re-enter on that computer codes for the next thirty days).

The problem with this tool is that if you use an Android need to create passwords for individual applications. Of course, you only have to type the password once for each installed application. On the other hand, Google recommends setting up a second mobile phone in case of not having access to the principal. You can also print a list of ten codes "emergency" if we can not access any of these phones.

Finally, we can also generate codes through a mobile app called Google Authenticator. After installing the Android market, add the Gmail account you already have been configured with the verification in two steps. In short, a way to improve the safety of our mail and avoid account thefts that happen very often, but can be a bit heavy if you use different computers on a regular basis.

Windows 8 hacked Safe Boot

Windows 8 hacked Safe Boot.
http://www.todaynewtechnology.com/wp-content/uploads/2011/10/windows8.jpegNothing is foolproof, much less when in a hyper-alpha version and show the world is a viral marketing ploy than a demonstration of the work constructed. 

But that's business, and Microsoft was quite sure what made ​​available to users by presenting the foundations of what will be safe boot your system, it did not expect was to meet with a story about that hack Windows 8. Is that the other side are security experts who move in the shadows, testing the shields, and in the case of Windows 8 and Safe Boot, these failed to prevent an exploit of only 14 kb was inserted into the MBR and give root access to the system.

Everything is ready to step in swiftly so that when carrying out the Security Conference in Mumbai Malcolm, nothing-beyond computers and display systems set up for this very reason, fail. 

For this conference that are high expectations to see what kind of advances and retreats has shown the computer security industry, attention is currently a researcher at the Austrian, who has become quite nervous about Microsoft engineers in the first instance when his creation did take it home safe insurance acclaimed Windows 8.

    The question is: Peter Kleissner is a developer and independent security analyst who has dedicated years to create exploits in bringing to light the vulnerabilities of each system it touches. To attend and get their hands on Windows 8 , Kleissner not think twice and jumped headlong into the MBR and the BIOS, trying them out on the best defense against an exploit of 14 kb that acts directly on the MBR, loaded from it resides in memory until you finish the boot process of Windows 8 and hacking the system and providing access to it.
El bootkit no respeta nada de esto y se hace con el acceso al root. - Hackean Windows 8 y su inicio seguro
The bootkit not respect any of this and be done with root access.
 Without there being any kind of information in the middle but a Twitter message Kleissner the bootkit the called Stoned Lite has good intentions, and that is why he has shared with Microsoft , along with all documentation relevant to their development and possible solutions, so that Redmond will make your changes to Windows 8 so that this condition can be overcome. 

To this will have to review the insurance system startup with UEFI, which is now free community resistance in the amount of difficulties that would arise when installing operating systems were not considered reliable Windows certification.

    There is less than an outside investigator account of an error in one of the biggest prides of Windows 8, so that the system that Microsoft has dubbed Malware killer due to the power of their efforts to prevent hacks from booting must now review their policies and act on quickly. 

By the way, still trying Kleissner would leave their country to Mumbai to explain how he hacked Windows 8, but a delay in the granting of your visa is complicating the matter. It seems that Kleissner has unfinished business with the Austrian justice for violating anti-piracy treaty.

¿Quien es Anonymous? Historia

¿Quien es Anonymous? Historia.Es un grupo de hackers a nivel mundial sin una jerarquía definida, que se unen en protestas de diferentes índoles (sociales, políticas, culturales, etc.), y que a través de este tipo de movimientos buscan la transparencia el en mundo, además de esta peculiaridad, el estar a favor de la piratería es otra de sus principales características.


Su principal arma son los DDoS (ataques de negación de servicio), con la cual han atacado sitios web de instituciones como Visa, Master Card, Paypal o de individualidades como Gene Simmons miembro de la banda de rock Kiss.
Sus ataques:

El primer ataque relacionado con Anonymous se remonta a mediados del año 2006 y es conocido con el nombre de “Great Habbo Raid of ‘06”, este movimiento consistió en el registro de cientos de integrantes de este grupo a la red Social “Habbo” (salas de chat con formas de habitaciones de hotel), todos ellos con el avatar de un hombre negro vestido con un traje gris, para posteriormente bloquear la piscina virtual de dicha red social, con la excusa de que estaba cerrada debido a que el agua estaba contaminada de SIDA.

Esta protesta estuvo inspirada en la noticia que había salido días antes en la que un parque de atracciones de Alabama había prohibido la entrada a la piscina a un niño con SIDA. Acción que causó disgusto entre los moderadores de esta red social, por lo que todos los usuarios que organizaron este movimiento, fueron bloqueados.

En contra del racismo

Otra de las protestas fue en contra del racismo; esta tuvo como víctima al estadunidense Charles Harold “Hal” Turner, activista con pensamiento racista, y que en estos momentos se encuentra bajo prisión debido a presuntas amenazas a jueces en su programa radial llamado “Hal Turner Show”.

La ofensiva de Anonymous consistió en un ataque de negación de servicios, gracias a la cual, Turner pagó miles de dólares por el ancho de banda consumido.

Proyecto Chanology

Este movimiento es quizá uno de los más importantes que Anonymous ha realizado, tiene como victima a la Iglesia de la Cienciología y dio inicio hace 3 años, el objetivo del movimiento: expulsar a la Iglesia del Internet. ¿El motivo? los integrantes de este grupo creen que los integrantes de la Iglesia son explotados económicamente.

Piratería

Se conoce como Operación Payback al conjunto de ataques coordinados a los oponentes de la piratería en Internet, en respuesta a los ataques que los defensores del “Copiright” emitieron contra sitios que fomentaban la piratería.

Movimiento en el cual estuvo involucrado el integrante de la banda de Rock Kiss, Gene Simmons, en respuesta a la petición de este, en la que exigía a las autoridades tomaran medidas más agresivas hacia las infracciones de copyright. Anonymous respondió inhabilitando sus dos sitios: simmonsrecords.com y gennesimmons.com.

El 9 de diciembre de 2010 Twitter canceló la cuenta de Anonymous y después, Facebook eliminó la página de Operation Payback, en lo que ya se considera por parte de miembros de Anonymous, como una guerra digital.

Ataques a Sony

El 5 de abril de 2011 Anonymous, comienza sus ataques DDoS a sitios web de Sony, estos son a raíz de la puesta en marcha, por parte de la compañía, de acciones judiciales contra los usuarios “Geohot” y “Graf-Chokolo”, los cuales lograron “hackear” la PS3. Dos días después, Anonymous anunció que detenía sus ataques contra Sony porque estaba perjudicando a los usuarios de PlayStation.





¿La amenaza a Facebook es real?

A principios de agosto de 2011 Anonymous anunció que realizaría un ataque que provoque el cierre de la red social Facebook el día 5 de noviembre. El motivo, según el propio grupo, es que Facebook vende la información de sus usuarios. Sin embargo expertos indican que se trata de una amenaza pirata, ya que la supuesta amenaza no se ha publicado en el blog o en la cuenta de Twitter oficial del grupo.
