TMZ has learned ... the celebrity hackers who have been on a tear over the last few days have added new victims to their ever-growing list -- Mitt Romney and Tiger Woods.
The hackers obtained full credit reports for both men. As for Mitt, the website has his social security number, phone numbers, as well as bank and other financial information.
As for Tiger ... ditto his social and what looks like complete financial data.
Also new on the list ... Kris Jenner and Stacia Hylton, Director of the U.S. Marshals Service.
We broke the story ... law enforcement sources tell us the FBI has known about the hackers days before the story broke, and they are "aggressively" investigating.
These hackers really have a set.
