So it appears that Rajat Khare is behind the shady Indian company Appin who appear to offer "hack for hire" services whilst fronting as a cyber security training company and aren't shy about using lawyers to manipulate the public record.
They're good at providing the services they offer insofar as they fulfill the contract, but these sorts of mercenary firms pretty much just phish people. They're quite good at it, but that is pretty much all they do.
Just wanted to make sure that was clear.
