Maybe you have entered your private key in a phishing website.
You can't identify the hacker only with that address. It seems that the account was new and created solely for that purpose (storage of stolen tokens/Eth). There's no outgoing transaction as of yet and the address continue to receive tokens.
What I noticed was most tokens received were limited to Utrust, PHI, STP, SPA, SDE, TKT, ebit, COPYTRACK, Transmission, GlobCoin Crypto Platform. Does one of these tokens send you an email or let you fill out something connected to your wallet? If yes, that might be the cause.
This is the only possible case that i think off on where he might entered his keys on a phishing site or do have an infected computer which do have keylogger or malware that do accumulates important wallet informations being stored up into your pc.There are lots of ways on how your keys would be exposed or compromised. I have seen such address it does still continue to have incoming transactions to the persons or wallet addresses that have been hacked. There no way to retrieve those coins when the transactions is already been done.Sorry for your loss.
