Hi Hive account@cwow2 and Hive account@keys-defender! Thank you so much for informing me. I viewed this link: https://hive.blog/faq.html#How_do_I_report_a_security_vulnerability and emailed privacy@hive.io about it. I am still waiting for the reply. Any other way for me to get help on this?

I checked my wallet and there was no stealing and hacking done based on the transactions listed. However, I went to account actions > keys & permissions to try and change my password as a form of security measure. I inputted my owner private key starting with "5" and clicked the generated new password. The new private keys are shown, I copied it to a safe place and downloaded it also. Then I clicked the "update keys" button but a yellow-orange remark stated "Opss, seems that the specific key format is not valid. Please be sure to use your 'owner' key as the master password is not accepted for this operation." Kindly help me on this issue.
