    Subject: Trillian weakly encrypts saved passwords
    
    Software:
    Trillian 0.73, possibly other versions.
    
    Issue:
    Weak "encryption" of saved passwords.
    
    Impact:
    Decryption of saved passwords.
    
    Vendor notified:
    3 Sept., 2002. No response.
    
    Severity:
    Medium. ish. The program only works locally, and only if the subject 
    has saved their password, and really if someone can get into your AIM 
    account, how earth-shattering is that??? However, since a lot of people
    use 
    the same password for everything...
    
    ---------------------
    
    Trillian is, according to trillian.cc, "...everything you need for
    instant 
    messaging. Connect to ICQR, AOL Instant Messenger(SM), MSN Messenger,
    Yahoo! 
    Messenger and IRC in a single, sleek and slim interface."
    
    Upon examination of the Trillian directory (which defaults to C:\Program
    
    Files\Trillian\ ), it appears that passwords are stored in ini files
    that are 
    located in {Path to Trillian}\users\{WindowsLogon}. The passwords are 
    encrypted using a simple XOR with a key apparently uniform throughout
    every 
    installation.
    
    The attached program takes, as command line argument(s), path(s) to
    these INI 
    files. It will then display a list of usernames, "encrypted" passwords,
    and 
    plaintext passwords.
