If you're using Amazon Web Services and your S3 storage bucket can be reached from the open web, you'd do well not to pick a generic name for that space. Avoid "example," skip "change_me," don't even go with "foo" or "bar." Someone else with the same "change this later" thinking can cost you a MacBook's worth of cash.
Ask Maciej Pocwierz, who just happened to pick an S3 name that "one of the popular open-source tools" used for its default backup configuration. After setting up the bucket for a client project, he checked his billing page and found nearly 100 million unauthorized attempts to create new files on his bucket (PUT requests) within one day. The bill was over $1,300 and counting.

"All this actually happened just a few days after I ensured my client that the price for AWS services will be negligible, like $20 at most for the entire month," Pocwierz wrote over chat. "I explained the situation is very unusual but it definitely looked as if I didn't know what I'm doing."
