Hello, my Steemians :)
I'm not 100% back to Steem yet but I'm also not 100% offline ;)
In this post, I'm going to tell you about Memo Key and how can be memo key used malicious.
Most of users know that you mustn't reveal your owner key to ANYBODY!!! KEEP IT OFFLINE!!!
People also know that you should never reveal your active key, but this also happen sometimes.
But how about memo key?
Memo key is used to read encrypted memos (You can encrypt memo if you add # in front of message).
So many people believe that memo key is harmless. It's NOT true!!!
Some people even use private memo key as memo when they send funds from exchange.
Memo key is used to login to some services as Minnowbooster, Smartsteem ...
So I just check transfer history of some accounts manually and I found few private memo keys.
I found around 10 private memo keys in 30 minutes and around 10 SBD was at risk.
I know it's not big amount, but your voting power can be burned, your Smartsteem account can be used for sending spam...
DO NOT REVEAL ANY PRIVATE KEY!
Stay safe & Steem on
