Doesn't it feel strange that all these strange things happens to one and only one online wallet, 99% of the cases is blockchain.info . Well after reading other stories here, I raise a reasonable doubt, why people should continue using it
if 99% of people use blockchain.info then 99% of the time issues raised are going to be about them
OP just save your private keys, create a new wallet and import the keys to the new wallet, the hacker probably has your identifier
