There has been a secure breach somewhere of some kind and therefore the account @steemengineteam has posting authority control over approx 3k accounts.
I have my authorities very securely managed and am not affected.
In case you are affected, I suggest you to remove posting authorities of all apps, that you don't trust and use frequently! Also change your master key!
Even if u're not affected, I still suggest you to actively manage your posting authorities!
How To Revoke Posting Authority
Go to https://www.steemd.com/@yourusername
scroll down and look at your posting authorities, you wanna revoke every one you don't trust and use frequently
you do so by pasting every app's name you wanna revoke into this url:
https://v2.steemconnect.com/revoke/nameofapp
just change "nameofapp" in the url to the name of the app according to steemd
in my case it was https://v2.steemconnect.com/revoke/engrave.app (but this was not the security leak, just to show you)
confirm using ur active key
Edit: you can revoke app's authority even faster, without pasting every name, using this url:
https://beta.steemconnect.com/auths
How to Change Master Key
after revoking all unnecessary and dangerous posting authority access, you also wanna change all your keys, easiest way to do so is by changing your master key
https://steemitwallet.com/change_password
paste your master key and safe your new one!
greets and a secure crypto experience! ;)

Ich denke das haben bereits andere erledigt. ;)
This is very useful! After SteemConnect changed the interface, I am finding it hard to look for the link to revoke my permissions
@tipu curate
Nice informations, especially In times of steem account hackings. Thanks!

Kann man irgendwo einsehen, wer betroffen ist? Würde sehr ungern alles revoken.
Sofern du nicht den Post von @steemengineteam gevotet hast solltest du eigentlich nicht betroffen sein.https://steemengine.net/ schauen..
Kannst in deinen Auths nochmal nach

Thanks for this small HowTo! It is complicate to find the right mode to revoke and this on is pretty easy...
Cheers!

I did it on my main yesterday @cadawg, reset my keys and now only have 2 apps authed!
Caution is better than indulgence :)
Definately! Moved most of my money into a less used account which only has my bots running on it!
Funny I never have been to Steem. I started with HIVE on Junge 2020. Thanks for that @manncpt and thanks @ibc for your votes on my posts ;-) Really awesome. Maybe I should make a new account on steem ...
haha yes maybe try it
