My guess is it was a pretty organized group either corporate or govt backed who did it as a cover to delete something that was archived they needed gone.

Whoever they are, we know one thing about them. They are dicks.

Why did they advertise that leak and cybersec advertising service Have I Been Pwned in the breach? Why did they hack a site where I literally just store websites? Why did they claim it was for Palestine? Seems like stupid fed shit to me. Also funnily enough I didn't even really need to change my password since I only had a few website saves and used a burner email

Pretorians.
