For the fourth time in as many months, some Pfizer Inc. employees have
been affected by a compromise involving personal data -- though this
time, in a somewhat indirect fashion and not as a result of a security
breach at the company itself.

The most recent incident involves Wheels Inc., a Des Plaines, Ill.-based
company that leases cars to Pfizer employees and their spouses.

In August, Wheels discovered that an online Web application used to
collect information from spouses of Pfizer employees failed to employ
proper encryption during the data transfer process, according to
Stratford Dick, director of marketing at Wheels. As a result, personal
information sent by about 1,800 spouses of Pfizer employees was
transmitted in a nonencrypted fashion to Wheels during a two-week period
in August, Dick said. The data included names, addresses, dates of birth
and driver's license numbers. Social Security numbers were not collected
as part of the process, Dick said.

Wheels collects the data in order to conduct a search of motor vehicles
records to qualify spouses to drive leased company cars, Dick said.

The compromise was brought to Wheels' attention by an employee's spouse,
Dick said, without elaborating on how that person had discovered the
problem. Following the discovery of the breach, Wheels shut down the
service and made sure data was being encrypted during transmission
before turning the service back on again, he said. The company has also
reviewed its security practices following the episode, he said, though
he provided no further details.

The company does, however, seem to resist characterizing the failure as
a breach. "We certainly don't think it was a breach," Dick added. "The
term 'breach' implies that our Web site where the information was stored
was hacked. There is no indication that the site was hacked or that the
information was stolen."

Even though the likelihood of anyone's information having actually been
intercepted or stolen during transmission is remote, Wheels has decided
to offer two-years' worth of credit monitoring and credit restoration
services free of charge to the 1,800 people affected, he said.

This is the fourth data compromise affecting Pfizer since this summer.
The first incident surfaced in June, when Pfizer said that an employee
had accidentally exposed Social Security numbers and other personal data
belonging to about 17,000 of its employees on a peer-to-peer network.
The exposure was caused by a file-sharing program the employee had
illegally installed on a company-owned system.

A month later, the company reported that two laptops containing
confidential employee data as well as proprietary company information
were stolen out of the locked car of an employee working for Axia, a
contractor for Pfizer.

Then in September, Pfizer Inc. disclosed that the personal data of as
many as 34,000 people may have been illegally accessed and downloaded
from a company computer system by a former employee. The compromised
information included names, Social Security numbers, dates of birth,
phone numbers, and bank and credit card information of employees, former
employees and health care workers.

Pfizer did not immediately respond to a request for comment for this
story.
