Not hacked.
This transaction is not showing in the blockchain at all
The blockchain is where confirmed Bitcoin transactions are permanently stored. blockchain.info is a site that tries to display information about both the blockchain and transactions that have been transmitted and are waiting for inclusion.
The first transaction didn't have an optional fee included. Due to the limited number of free transactions that miners will include in a block, it may have to wait quite a while.
A second transaction sending all of your money may need to wait for the first transaction to confirm. It likely is funded by "change" back to your wallet that is in the first transaction.
There are currently 5MB of unconfirmed transactions waiting to be included in 0.5MB blocks, which happen every 10 minutes, and most of these include fees and are given priority over non-paying ones.
