According to their website [1], they seem to be trying to establish a reputation for pentesting social-media and websites. What better way to garner interest than by hacking a couple major companies?
What I don't understand is how they think these "marketing" tactics will establish anything but a negative reputation for their brand. Seems to me like they are happily waving a massive red flag that says, "we break the law all the time and can't be trusted!"
Yes, no, maybe. Irrelevant from a marketing perspective. It doesn't matter if you're trustworthy. If you are perceived as untrustworthy, businesses won't want to hire you.
