The Electronics Frontiers Australia (EFA) group reports that the export of Public Domain crypto software is already banned in Australia, the USA, New Zealand, France and Russia, since these states do not use "the general software note" of the Wassenaar agreement. That wasn't surprising, seeing as BMW is one of the main backers of NGTP.

Since it does not answer either, the correct VIN can't be easily figured out as is the case with the Combox. The surprising thing about what had just happened was, that the cellular connection between the vehicle and the BMW servers could be logged without problems in my emulated network. Based on exclusive information from an informant belonging to the carder milieu, c't and Die Zeit were able to collect the missing pieces of the puzzle and analyse the software that was most likely also used in those cases.

Having knowledge of the crypto algorithms and key table, I could easily decode and analyse the message.

According to Ross Anderson, of the Foundation for Information Policy Research (FIPR), while it was a good thing that key escrow was laid to rest, this does not mark the end of the matter. There are, however, service providers that offer to take care of this. Using IDA Pro, I was quickly able to identify several encryption and hashing algorithms in the firmware. The first eight characters of this number identify the device (Type Allocation Code, TAC).

To analyse the firmware code, I used the tool IDA Pro from Hex-Rays. This meant the text message wasn't enough to open the doors and the system required further data from the backend (see diagram). This had to start with a text message since a data connection wouldn't otherwise be possible to a parked car with its engine switched off. These apps even allow for remote locking and unlocking of the car doors. Unlocking the doors does not leave any traces and is completely inconspicuous even on crowded streets. The text message is scrambled and does not reveal any recognisable patterns whatsoever. Since it did not receive any data, the connection was terminated and nothing further happened.

The Federal Department of Justice did not want to confirm to Telepolis the existence of the Reno letter.

Letter sent kryptowährungen gesellschaftliche auswirkungen last May by Ms Reno to German Federal Secretary of Justice Herta Daeubler-Gmelin. In a last ditch effort, I analysed a conspicuously random looking block of data included in the firmware.

It's block length is shorter compared to several other crypto algorithms, leading to shorter messages, but the same is true for 3DES (Triple-DES) and that algorithm is at least still considered mostly secure. ADAC is demanding that computers that are included in cars have State of the Art protection against manipulation and illegal access. Still, what are the options for car owners who are nervous despite the assurances from the manufacturer?

The Combox's CPU is an SH-4A, a powerful 32-bit RISC processor from Renesas. Being an optimist, I initially assumed unique keys were generated for each car, stored in the V850ES micro controller and sent from there to the cellular modem. According to BMW, the certificate of the server is now being checked as part of this. I now had sufficient knowledge to emulate all components of the unlocking feature.

Its ConnectedDrive technology has been on the market for several years now. That's no trivial task, as the chip is packaged using a BGA - after desoldering, it has to be reballed. However, an investigation in the current issue of c't magazine shows that fraudsters are using cloned cards to great effect. To sign the messages, three methods were implemented: DES CBC-MAC, HMAC-SHA1 and HMAC-SHA256. The protocol was once again NGTP, but this time different signing and encryption methods where used: AES128 instead of DES and HMAC-SHA256 instead of DES CBC-MAC. Since looking for the keys in lukrative kryptowährung 2021 this case would have been a lot of work, I decided to keep analysing the protocol for the emergency calls instead.

The SH-4A's larger power demands would drain the battery too quickly. My tests with several other BMWs reassured me they would. It writes an app with the apt name of MacGyver and some additional data onto Java smart cards which are freely sold over the Internet. Still there are arguments about the definition of the term 'Public Domain'. Launched three years ago, the Scrambling for Safety conferences came into being as a response to the drawing up of the first draft bill involving electronic commerce by the then Tory government.

This message seems to have debug character since it is actually being processed by the cellular modem. Like c't, ADAC is interested in the privacy and consumer protection implications of the data transmitted in the use of this system. Das spart enorme Kosten und ist leichter wartbar: Man managt ein Ganzes Grid wie ein einfaches System. This might include the auxiliary heating system or, with electric cars, the charging of the main battery.

The transaction is then processed online via Static Data Authentication (SDA) in accordance with the EMV standard. The car had sent a simple HTTP Get request; there was no encryption with SSL or TLS in transit. Some services do not encrypt messages in transit between the car and the BMW backend.

In testing this, I learned some additional things. Following this, the Combox initiated a data connection to the BMW backend servers via the cellular network and tried to access data there. Following this, I went on the hunt for the crypto keys again. Research on the Internet provides another way: by downloading diagnosis software intended for BMW service garages which documents the pin configuration.

I figured out the pins for power lines and the emergency button on the connector by looking at the modules on the mainboard. When the emergency button is pressed, the Combox sends a text message and then starts a voice call. After my successful attempt to decrypt and decode the emergency text message, I turned my attention back to the car itself. After the vehicle had received the text message, it took approximately one minute for the systems connected to the main processing unit to boot up. On the other hand, so far I had only looked at the emergency text messages.

The Combox discloses the VIN via NGTP error messages. The TCB ignores messages that do not include the correct VIN. A card printer and an embossing machine turn these cards into an approximation of the real thing that is pretty hard to spot, unless you specifically know what to watch out for. This step was needed, because NGTP only makes suggestions on how a protocol is built, it does not specify actual implementation details.
