Not really. The victim here is the people whose information has been distributed, not the system (and the people running it) the information was exfiltrated from.

If we are going to use an SA analogy, this is closer to the recent case of a hotel chain where there were several instances of staff giving “randoms” keys to rooms that they should not have. Best practise procedures were not being followed, the ne'er-do-wells took advantage of this, someone else suffered as a result.

If you process personal data, you must secure it against attacks. Are you suggesting that they could just put the addresses of their customers on their website with a warning not to download them, and if someone downloaded them anyway then it would be the fault of that person that they were leaked?
