TJX Companies, the mammoth US retailer whose substandard security led to
the world's biggest credit card heist, has fired an employee after he
left posts in an online forum that made disturbing claims about security
practices at the store where he worked.
Security was so lax at the TJ Maxx outlet located in Lawrence, Kansas,
that employees were able to log onto company servers using blank
passwords, the fired employee, Nick Benson, told The Register. This
policy was in effect as recently as May 8, more than 18 months after
company officials learned a massive network breach had leaked the
details of more than 94 million customer credit cards. Benson said he
was fired on Wednesday after managers said he disclosed confidential
company information online.
Other security issues included a store server that was running in
administrator mode, making it far more susceptible to attackers. He said
he brought the security issues to the attention of a district loss
prevention manager name Allen in late 2006, and repeatedly discussed
them with store managers. Except for a stretch when IT managers
temporarily tightened password policies, the problems went unfixed.
"I was basically hitting a glass wall," said Benson, a 23-year-old
freshman at the University of Kansas who worked at TJ Maxx beginning in
October 2005. "Not one single thing was done. My store manager even
posted the password and username on a post-it note. I told her not to do
that."
So last August, Benson took to Sla.ckers.org, a website dedicated to web
application security, and began anonymously reporting the shoddy
practices in this user forum. Over the next nine months, he left eight
posts in which he chafed at the password policy and what he should do
about it.
"I am not sure if this is just an isolated incident within this specific
store, but it goes to show that you can't trust a company to protect
your information, especially TJX," Benson wrote under the moniker
CrYpTiC_MauleR. "Today was a very sad day for me =o("
A TJX spokeswoman declined to comment for this story and turned down our
request to discuss the company's policies for passwords and other
security matters.
Benson's May 8 posting was prompted by news that managers had changed
the password for employees to access the store server. Inexplicably, it
was set to blank. When Benson first began working for TJX, his password
was the same as his user name, he said. Then came word in January 2007
that unknown hackers had brazenly intruded on the company's network over
a 17-month period. For a time following the disclosure, TJX employees
were required to use relatively strong passwords. The change to a blank
password clearly represented a step backward, Benson thought.
The posts eventually caught up to Benson. On Wednesday, while marking
down items on the TJ Maxx retail floor, he was summoned to the store
office. Inside, a regional loss prevention manager told him his
critiques had come to the attention of the company hired to monitor
internet postings about the retailing giant. The manager told Benson he
was being fired for disclosing confidential company information.
No one at Sla.ckers.org was willing to defend TJX or the shoddy security
practices it is accused of following, but some have questioned Benson's
decision to speak so openly.
"I would assume your disclosure of your company's inner server workings
on the internet means that they can't trust employees to protect their
information?" one forum participant wrote in a response to Benson's
posts.
But critiques like that seem to overreach. Benson's disclosures weren't
specific enough to give attackers information needed to successfully
breach TJX's networks. And when you consider the right of TJX's
customers and employees to know that their data may be at risk, it's not
unreasonable to call him a whistleblower.
The account has us wondering if other TJX employees have tales similar
to Benson's. If so, please contact your reporter using this link.
(Anonymity assured.)
For Benson's part, he has no regrets. "They're telling the public
they're PCI compliant," he said, referring to so-called payment card
industry security rules governing businesses that accept credit and
debit cards. "That I think is unethical."
But he says his actions were also fueled by a healthy dose of
self-interest.
"My information is still on that server," he continued, referring to the
machine that sits in an office at the TJ Maxx where he once worked. "So
if their network is insecure, then my information is insecure. I'd
prefer they get it fixed." ®
