Google Chrome:

Chrome Passwords are stored in a SQLite file the sites name and sites username is in clear text but the password is seeded in a Triple DES algorithm. The file is called Web Data and is stored in the following location


XP – C:\Documents and Settings\Username\Local Settings\Application Data\Google\Chrome\User Data\Default

Vista – C:\Users\Username\Appdata\Local\Google\Chrome\User Data\Default


Trillian:

Note- I have just realised the new version of trillian the passwords made be stored/encrypted differently.

Trillian Passwords are stored in .ini files the first character of the password is encrypted with XOR with the key 243 then the password is converted into hex. The file is based on what the password is for so if it was icq it would be icq.ini (for new versions I think they are all stored in a file called accounts.ini or something similar if you open it up with notepad you will see all the data + the encrypted password). The files are stored in the following location:

XP (old version) – C:\Program Files\Trillian\users\

XP (new version) – C:\Documents and Settings\Username\Local Settings\Application Data\Trillian\user\global – I am not sure on exact but it is somewhere there.

Vista (old version)- C:\Program Files\Trillian\users\

Vista (new version)- C:\Users\Username\Appdata\Roaming\Trillian\user\gl obal



MSN /Windows Live Messenger:

MSN Messenger version 7.x: The passwords are stored under HKEY_CURRENT_USER\Software\Microsoft\IdentityCRL\C reds\[AccountName]

Windows Live Messenger version 8.x/9.x: The passwords are stored in the Credentials file, with entry name begins with “WindowsLive:name=”. They a set of Win API functions (Credential API’s) to store its’ security data (Credentials). These functions store user information, such as names and passwords for the accounts (Windows Live ID credentials). Windows Live ID Credential records are controlled by the operating system for each user and for each session. They are attached to the “target name” and “type”. If you are familiar with SQL you can think of target name and type as the primary key. Table below lists most frequently used fields in Windows Live ID Credential records.



Paltalk:

Paltalk Passwords are using the same password encryption algorithm. Paltalk passwords are stored in the registry. To encrypt the new password Paltalk looks at the serial number of the disk C:\ and performs a mix with the Nickname. The resulting string is then mixed again with the password and some other constants. The final string is then encoded and written to the registry.

AIM, ICQ and Yahoo Messenger passwords that are stored by Paltalk are encoded by BASE64 algorithm.

The passwords are stored in the Registry, under HKEY_CURRENT_USER\Software\Paltalk\[Account Name]
