    27Apr98 GERMANY: COMPUTER HACKERS COPY MANNESMANN MOBILE PHONE SIM CARD.
    
    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.
