Krebs told ABC News that he found the confidential data on servers he said belong to those responsible for last month's massive Adobe hack.
The database includes financial records, numbers for no limit credit cards and details of alleged drug use and sex in the limos.
Krebs did not divulge the more scandalous details, but wrote on his blog that Trump required a clean, new car when using a limo in Las Vegas in 2007.
Tom Hanks is called VVIP and the driver is instructed not to use his cell phone or radio when he is in the car, the records state.
