'12345'

While we're talking passwords, here's another one from recent news:
The attack took place overnight Sunday and the target was the mail server of the Syrian Ministry of Presidential Affairs. Some 78 inboxes of Assad's aides and advisers were hacked and the password that some used was "12345". Among those whose email was exposed were the Minister of Presidential Affairs Mansour Fadlallah Azzam and Assad's media adviser, Bouthaina Shaaban.
