Lawyers for a Portuguese computer hacker said on Monday he was responsible for revealing the dealings of Angolan billionaire Isabel dos Santos, a corruption scandal with fallout across Europe and Africa.

The hacker, Rui Pinto, handed over a hard drive "containing all data related to the recent revelations concerning Ms. Isabel Dos Santos’s fortune" to a whistleblowing organisation in 2018, his lawyers said.
The tycoon daughter of former Angolan president Jose Eduardo dos Santos now faces a slew of corruption allegations stretching across Angola's state oil and diamond industries and banks -- all of which she has denied in interviews from London.
