Wow!

Lets take the article at face value: "The financial technology company said it has reversed the code change that caused the incident, blocking attackers' access to the data one day after discovering the breach."

Great thats your bug. Key word here being BUG. Your name next to the commit that caused this.

Should you go to prison? Probably not.

Tell me you never had a bug, a security hole, never took production down. Never made a mistake. Tell me that you want to go to jail for human error. Not intent, error.
