Jacob Appelbaum (n. 1983) es un investigador independiente de seguridad informática y un hacker. Fue un empleado de laUniversidad de Washington,5 y es un miembro importante del Proyecto Tor.1 Appelbaum es conocido por representar aWikiLeaks en la conferencia Hackers on Planet Earth de 2010.2 3 4 Subsecuentemente, ha sido buscado muchas veces por agencias de ley estadounidenses, las cuales obtuvieron una orden de cateo de los datos de su cuenta en Twitter, deteniéndole doce veces6 en la frontera estadounidense después de viajar al extranjero, y le decomisaron una computadora portátil y varios teléfonos móviles.

Appelbaum, bajo el alias «ioerror», ha sido miembro activo del grupo de hackers Cult of the Dead Cow desde 2008,7 es cofundador del hackerspace de San Francisco Noisebridge,8 junto a Mitch Altman. Ha trabajado para Greenpeace[cita requerida]y ha sido voluntario de la Ruckus Society y de la Rainforest Action Network.9 También es fotógrafo[cita requerida] y es embajador del grupo de arte monochrom.10

Appelbaum spoke of a NSA program that allows its analysts to search through vast databases containing e-mails, IMs and the browsing histories of millions of people. Called XKeyscore, the program was designed to develop intelligence from the Internet.

Report: UK and US spies have cracked BlackBerry’s BES encryption


By Peter Sayer
09 September 2013

The U.S. National Security Agency is able to read messages sent via a corporate BlackBerry Enterprise Server (BES), according to a report by German news magazine Der Spiegel. The purpose of this spying is economic or political, and not to counter terrorism, the magazine hints.

The report, published in English on Monday, cites internal documents leaked by former NSA contractor Edward Snowden.

Governments have long demanded that BlackBerry provide access to encrypted messages carried by its email and BlackBerry Messenger (BBM) services, to allow them to monitor for terrorist activity.

BlackBerry has complied in the case of its consumer-grade BlackBerry Internet Service (BIS), notably providing the Indian government with access to consumer messages. Indeed, Der Spiegel cited NSA documents claiming that since 2009, analysts have been able to see and read

Car immobilizer hacking [SIGINT13] Speaker: Karsten Nohl

lecture: Car immobilizer hacking

Car manufacturers nicely illustrate what _not_ to do in cryptography.

Immobilizers have for a long time increased the difficulty of stealing cars. Older immobilizer transponders defeated thieves by requiring non-trivial RF skills for copying keys. Current transponders go one step further by employing cryptographic functions with the potential of making car cloning as difficult as breaking long-standing mathematical problems. Cryptography, however, is only as strong as the weakest link of key management, cipher strength, and protocol security. This talk discusses weak links of the main immobilizer technologies and their evolution over time.

SIM cards are prone to remote hacking by Karsten Nohl


SIM cards are the de facto trust anchor of mobile devices worldwide. The cards protect the mobile identity of subscribers, associate devices with phone numbers, and increasingly store payment credentials, for example in NFC-enabled phones with mobile wallets.

With over seven billion cards in active use, SIMs may well be the most widely used security token in the world. Through over-the-air (OTA) updates deployed via SMS, the cards are even extensible through custom Java software. While this extensibility is rarely used so far, its existence already poses a critical hacking risk.

Cracking SIM update keys. OTA commands, such as software updates, are cryptographically-secured SMS messages, which are delivered directly to the SIM. While the option exists to use state-of-the-art AES or the somewhat outdated 3DES algorithm for OTA, many (if not most) SIM cards still rely on the 70s-era DES cipher. DES keys were shown to be crackable within days using FPGA clusters, but they can also be recovered much faster by leveraging rainbow tables similar to those that made GSM’s A5/1 cipher breakable by anyone.

To derive a DES OTA key, an attacker starts by sending a binary SMS to a target device. The SIM does not execute the improperly signed OTA command, but does in many cases respond to the attacker with an error code carrying a cryptographic signature, once again sent over binary SMS. A rainbow table resolves this plaintext-signature tuple to a 56-bit DES key within two minutes on a standard computer.
