It is not steemconnect that has been hacked but utopian-io... And saying hacked is not a very precise word because the problem was from inside the platform.... Some tokens had been leaked from the inside of utopian-io and with that someone got the control of few keys to downvote or upvote some posts without their consensus. No danger on your wallets but it is for sure a good thing to revoke your tokens from all platforms and change your password. This was in short the last update given by utopian-io. Utopian-io blocked this process and revoked all posting tokens so now everything should be safe. They are investigating on who did this action of leaking tokens and will work on some safety measures to protect all tokens stored in their database. This stab was kind of needed so that they increase safety from the inside
