I know what I'm talking about as I used to unfortunately hang out in the same IRC servers that she did (l0de radio).
Her working at AWS (where she was fired from) let her know exactly how and what to target in order to steal the data she was able to find and obtain. She had prior knowledge on what companies to snoop. I'd say thats using insider info to your benefit. Yes there are also common scripts that bug bounty H1 and Bugcrowd users use to pwn S3 buckets.
she also did was into cryptomining on hacked servers
>Ms. Thompson also used her access to Capital One’s servers to mine cryptocurrency
