Members of the Chaos Computer Club have succeeeded in finding a weak spot in the mobile telecoms network D2. They were able to duplicate a D2 SIM card and thus gain access to the digital mobile telecoms network D2. More than four million people use the D2 network which is operated by Mannesmann Mobilfunk GmbH (Duesseldorf). Mannesmann said that the cloning poses no significant security risk to clients. In order to clone a SIM card, the hackers had to have both a copy of the original SIM card for at least 11 hours and know the PIN number. Scientists at the University of California and the Smartcard Developers Association in the USA already reported weaknesses in smaller mobile telecoms networks at the beginning of April which work on the same GSM standard as the German networks D1, D2 and E-Plus.
