Gobiernos en guerra contra WhatsApp por su cifrado de extremo a extremo – El Mostrador

Tras el ataque al Parlamento Británico ocurrido la semana pasada, los políticos británicos han exigido que Whatsapp y otras aplicaciones de mensajería instantánea proporcionen acceso a la policía y fuerzas de seguridad para así poder monitorear conversaciones terroristas. Sin embargo, los expertos en tecnología discuten que abrir las “puertas traseras” de los servicios de mensajería popular, las cuales usan cifrado de extremo a extremo, arrojaría una serie de problemas.

With Facebook No Longer a Secret Weapon, Egypt’s Protesters Turn to Signal

Although the police in Cairo sealed off parts of the Egyptian capital where protests scheduled on Facebook were to have taken place on Monday, opposition activists managed to stage brief rallies that resembled flash mobs, calling for an end to military rule and the cancellation of a deal to surrender two islands to Saudi Arabia.The fact that Facebook is now so closely monitored by the security forces prompted one leading activist to offer an online tutorial in how to use a new tool, the encrypted messaging app Signal, to help protesters find each other on the city’s streets, and stay one step ahead of the authorities.

Sale de la cárcel un ejecutivo de Facebook detenido en Brasil | Internacional | EL PAÍS

El vicepresidente de Facebook para América Latina, Diego Dzodan, ha salido de prisión apenas un día después de ser detenido en São Paulo. Un tribunal ha revocado la orden de cárcel del ejecutivo, que entró en prisión el martes por orden de un juez de la ciudad de Lagarto (Estado de Sergipe, al noroeste del país). El magistrado acusó a Dzodan de negarse reiteradamente a revelar mensajes intercambiados en la aplicación de mensajería WhatsApp, propiedad de Facebook desde 2014. Según las autoridades, las conversaciones que requería la Policía Federal eran pruebas esenciales en una investigación sobre crimen organizado y tráfico de drogas.

The Insidiousness of Facebook Messenger's Mobile App Terms of Service | Sam Fiorella

The Insidiousness of Facebook Messenger’s Mobile App Terms of Service | Sam Fiorella.

How much access to your (and your friends’) personal data are you prepared to share for access to free mobile apps? I suspect the amount is significantly less than that which you actually agreed to share when blindly accepting the Terms of Service.

Case in point: Facebook’s Messenger App, which boasts over 1,000,000,000 downloads, requires the acceptance of an alarming amount of personal data and, even more startling, direct control over your mobile device. I’m willing to bet that few, if any, of those who downloaded this app read the full Terms of Service before accepting them and downloading the app.

The Facebook Messenger app is a standalone version of the instant chat feature within the social network. You can easily access this within the Facebook app on your mobile device, but opening the full application also requires more memory, bandwidth, and battery life. As a result, Facebook offers this one feature as a standalone app in which you can instantly chat with your Facebook friends without having to launch the full Facebook app.

If you’re one of those 1,000,000,000 people who have downloaded this app, take a moment to read the following. I’ve posted, word for word, a few of the most aggressive app permission you’ve accepted.

    • Allows the app to change the state of network connectivity


  • Allows the app to call phone numbers without your intervention. This may result in unexpected charges or calls. Malicious apps may cost you money by making calls without your confirmation.


  • Allows the app to send SMS messages. This may result in unexpected charges. Malicious apps may cost you money by sending messages without your confirmation.


  • Allows the app to record audio with microphone. This permission allows the app to record audio at any time without your confirmation.


  • Allows the app to take pictures and videos with the camera. This permission allows the app to use the camera at any time without your confirmation.


  • Allows the app to read you phone’s call log, including data about incoming and outgoing calls. This permission allows apps to save your call log data, and malicious apps may share call log data without your knowledge.


  • Allows the app to read data about your contacts stored on your phone, including the frequency with which you’ve called, emailed, or communicated in other ways with specific individuals.


  • Allows the app to read personal profile information stored on your device, such as your name and contact information. This means the app can identify you and may send your profile information to others.


  • Allows the app to access the phone features of the device. This permission allows the app to determine the phone number and device IDs, whether a call is active, and the remote number connected by a call.


  • Allows the app to get a list of accounts known by the phone. This may include any accounts created by applications you have installed.


¿Por qué los usuarios abandonan WhatsApp y se mudan en masa a Telegram?

¿Por qué los usuarios abandonan WhatsApp y se mudan en masa a Telegram?.


 

Más de 200 mil personas están migrando cada día de Whatsapp a Telegram en España, en México Argentina y Colombia  el ritmo es 20,000 personas diariamente 

¿Qué es lo que está motivando este cambio? ¿Qué está haciendo que la gente abandone en masa a Whatsapp?

Pues al parecer la clave está en la gratuidad del servicio y en su seguridad.

Telegram es un servicio de código abierto en el que si sabes programar puedes desarrollar tu propia versión. Funciona en los iPhone, en los sistemas Android, en Windows y en Mac.

La información se mantiene en la nube y se pueden crear grupos de hasta 100 personas. El chat es cifrado y puede autodestruirse  de los servidores centrales si lo deseas.

La Agencia de Seguridad Nacional (NSA) de Estados Unidos accede a 200 millones de mensajes telefónicos de texto (SMS) cada día de manera indiscriminada, informó el jueves el diario británico The Guardian.

Esta información, procedente de una investigación entre el diario y la cadena de televisión Channel 4, se basa en los documentos transmitidos por el ex informático del NSA Edward Snowden, refugiado en Rusia.

El programa del NSA sobre SMS, que tiene el nombre de “Dishfire”, accede “a casi todo lo que puede”, más que a las comunicaciones de personas concretas, dicen documentos del servicio de espionaje británico citados por The Guardian.

El diario cita además un documento de la NSA de 2011 titulado “Los SMS: una mina de oro a explotar”, que revela que Dishfire permitió acceder a 194 millones de mensajes por día en abril de aquel año.

The National Security Agency has collected almost 200 million text messages a day from across the globe, using them to extract data including location, contact networks and credit card details, according to top-secret documents.

The untargeted collection and storage of SMS messages – including their contacts – is revealed in a joint investigation between the Guardian and the UK’s Channel 4 News based on material provided by NSA whistleblower Edward Snowden.

The documents also reveal the UK spy agency GCHQ has made use of the NSA database to search the metadata of “untargeted and unwarranted” communications belonging to people in the UK.

The NSA program, codenamed Dishfire, collects “pretty much everything it can”, according to GCHQ documents, rather than merely storing the communications of existing surveillance targets.

The NSA has made extensive use of its vast text message database to extract information on people’s travel plans, contact books, financial transactions and more – including of individuals under no suspicion of illegal activity.

An agency presentation from 2011 – subtitled “SMS Text Messages: A Goldmine to Exploit” – reveals the program collected an average of 194 million text messages a day in April of that year. In addition to storing the messages themselves, a further program known as “Prefer” conducted automated analysis on the untargeted communications.
