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 ICQ®, 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. Evan Nemerson enemerson@coeus-group.com http://www.coeus-group.com
