      Friends amazon account got hacked. They logged in, changed the e-mail and then registered a new account using the old e-mail. Made me realise "change e-mail" funcitonality should require e-mail access, not just password access. #infosec #thoughts

      Also, is stealing amazon accounts to run miners on EC2 a thing?

          Yes I’ve heard stories of people scraping Github for API keys to run miners. Someone I know got a $25.000 bill after someone stole their keys. In the end Amazon cleared it but be sure to get in touch with them if you suspect malicious activity!

          Oh yes. It is actually why I stopped using Amazon Glacier, because (at least back then) Amazon will force you to pay for all the power the attacker used, and you could not have Glacier without an account where you could buy computing power.

          Wouldn't be surprising. People write scripts to slurp up credentials and API keys posted to github to then use them to run miners...
