I could not agree more. Better safe than sorry, and now that the solution has scaled and already has a dedicated consumer base of thousands of users, it will immediately attract unscrupulous eyes and unwanted attention as hackers will be interested in extracting some illegal value for themselves. The Steemit community does not need those headaches! Disrupting the legacy centralized social media tools is hard enough on its own!
Any cryptocurrency with a Top 5 market cap needs to be especially careful, not just from an authentication standpoint (some users have suggested implementing a two-factor authentication module for Steemit, which would help but that is only the beginning), but also from a regular site audit standpoint; these cryptocurrencies need to invest in the proper business continuity planning and disaster recovery management solutions, as well as ensuring that they have access to cyber security and digital threat forensic experts to help 'stress test' the system. This is only the beginning and there will be more and more attempts going-forward.
One last point worth mentioning, the actual Steem cryptocurrency was not impacted or attacked in this particular incident, it was only the Steemit.com website and that has since been corrected by Ned and his team.
Long live Steemit!
good to know the difference right? the steemit website got hacked not steem
