Yes actually, I know someone who did business with them many years ago (before the advent of LLMs), although for a smaller sum than the advertised top payouts (the vulnerability they had was much less important).

Why post these random unsubstantiated claims on HN?

Yes, I have briefly done business with them as well. We also worked with Bekrar and Vupen briefly. Albeit, it was done through a broker. The second time around, we exited negotiations.

Just because they're exclusive about their clients doesn't mean they're not real. Their impact and effectiveness is a separate topic though. I don't think they're still actively operating or taking new clients, at least.

btw: "Oh, so you've done x?" What a snarky and confrontational way to ask someone something. Especially when it's asserting a well documented company and person is "not real".

I do, as a matter of fact.

My lawyer says I can't answer that
