P2P lapses ‘put credit card data at risk’

Credit card information can be leaked via networks. Online filesharing services can enhance customers’ chances of falling victim to credit card fraud, a technology expert has indicated.

Writing in his blog, IDTheftSecurity.com analyst Robert Siciliano said that people can unintentionally reveal sensitive personal information such as credit card data when they set the services up on their home computers.

To get on to a P2P network, users are commonly required to share software such as music files with other members.

However, Mr Siciliano pointed out that some people make important files viewable when they set up their network profiles to allow this sharing.

“This can result in data breaches, credit card fraud and identity theft,” he added.

“I’ve seen numerous reports of government agencies, drug companies, mortgage brokers and others discovering P2P software on their networks after sensitive data was leaked.”

The comments follow the accidental leaking of a confidential US Congress memo detailing House of Representatives members who are under investigation for ethical lapses.

It later emerged that the information had originally been made public through a junior official’s P2P account.
