I logged in to etherflyer with my private keys and after months of leaving it logged in, I scanned my wallet today and only to find out that my ether has been moved to a new wallet. Is that my fault as in a friend of mine stealing my coins or it may be from the etherflyer team?
All my other wallets are intact.
My wallet address on etherscan: https://etherscan.io/address/0xd18a2aea95b1e992402be37e368c510fba8b7ae0
Now moved to: https://etherscan.io/address/0x7ab9da14bf20fad590201c52b946bad767a584f2

Please I need your your advice. Thanks
