To be fair, Germany is unusually harsh on security researchers. As far as I know (but German law is not my forte) there's no exclusion for "ethical hacking". I remember reading about many German cases that went like: * A security researcher discovers that the main database of some service is available publicly with default password * They notify the company * They get sued for unauthorized access to the company's data This wouldn't happen in my (also European) jurisdiction, because as long as your intention is to fix the vulnerability you found, and you notify the company about the problem, you're in the clear.
