This looks like it was due to the recent malleability issue affecting the bitcoin network.
It appears the funds have been returned to the original account.

"Hi there,
Thanks for reaching out. This looks like a transaction that might have been affected by the transaction malleability issue that is currently affecting the bitcoin network. In order to address the issue, we are re-initiating affected outgoing transactions. The original transaction will appear as pending for a few hours and then disappear without ever completing.
You can read more about transaction malleability on our community post here:

Kind regards, Please let us know if you need further assistance."

The warning given on blockchain.info may be too extreme.
As long as the transactions in your wallet have been confirmed,
then they are safely in your wallet.
I.e. there is no further action needed on your part.
I hope this helps. Please let me know if you have any other questions.
Regards,
David

Oct 13, 08:58Hello,
There is currently an attack on the bitcoin network that is causing these double transactions to appear. This attack is effecting almost all bitcoin transactions - not just Blockchain.info users. Your funds are *not* at risk and these duplicate transactions will never confirm. After 24-72 hours they should be rejected by the bitcoin network as invalid, which they are. When sending transactions during this attack you may see it appear twice. One will likely be marked as a double spend, which can cause a great deal of confusion.
We understand this is an inconvenience to our users, and all users of bitcoin. With your funds not at risk during this attack the most anyone can do is to wait for these transactions to be rejected. There isn't anything Blockchain.info can do to clear this issue up faster, as this is an attack on the bitcoin network itself. You can read more about the attack here -
