An online broker for limousine and Town Car services has suffered a hack that spilled financial and personal information for more than 850,000 customers, including real estate mogul Donald Trump, basketball star LeBron James, actor Tom Hanks, and many more of the world's rich and famous, according to a published report.

The data trove was found on the same servers that stored source code for Adobe's ColdFusion and Acrobat applications, fueling speculation that the same hackers may be behind both attacks, KrebsonSecurity's Brian Krebs reported Sunday night. The archive file, which was listed as belonging to a firm called CorporateCarOnline, contained data for 241,000 high- or no-limit American Express accounts, as well as a wealth of personal details about the company's well-to-do clientele, including their pick-up and drop-off locations and travel itineraries.

"This database would be a gold mine of information for would-be corporate spies or for those engaged in other types of espionage," Krebs wrote. "Records in the limo reservation database telegraphed the future dates and locations of travel for many important people. A ridiculously large number of entries provide the tail number of a customer’s plane, indicating they were to be picked up immediately upon disembarking a private jet."

Krebs didn't rule out the possibility that the data was used to target Kevin Mandia, the CEO of Mandiant, a firm that specializes in helping companies defend against computer espionage attacks. In October, Mandia told a Foreign Policy reporter that he received several booby-trapped PDF files in e-mails posing as billing invoices for recent limo rides. Among the 850,000 exposed records were those for Mandiant employees, including Mandia.

Besides fueling corporate or political espionage attacks, the breach could also support more titillating pursuits. Krebs wrote: "Any two-bit tabloid would have an absolute field day with this database," Krebs wrote. "Simple text searches for certain words ('sex,' 'puke,' 'arrest,' 'police,' 'smoking pot') reveal dozens of records detailing misbehavior and all kinds of naughtiness by executives, celebrities, and people you might otherwise expect to behave civilly."
