The week has started with a fresh data leak highlighting the ongoing danger of failing to protect information from hacking attacks.
Last month saw several high profile leaks including Play.com, Trip Advisor and the attack on RSA and now various US firms including Citigroup have had customer information leaked after online marketer Epsilon was penetrated.
The breach is being described on some wire reports as the largest in the US because of the number of firms that are implicated, including Walgreen, TiVo and Capital One.
One of those retailers that has also been impacted is online book retailer AbeBooks which has emailed its customers to warn them that details might have been comprised.
"We have been informed by Epsilon, a third-party vendor we use to send e-mails, that an unauthorized person outside their company accessed files that included e-mail addresses of some AbeBooks customers. Epsilon has advised us that the files that were accessed did not include any customer information other than email addresses," it stated.
The latest attack adds to the numerous examples that are already mounting up this year and seem to back up trends already noted by experts that hackers are focusing their efforts on gaining sensitive data more than just going for cash.
