Millions of EBay’s on-line shoppers are thinking of new passwords today, thanks to a cyberattack that stole information such as customers' names, encrypted passwords, email and physical addresses, phone numbers and dates of birth.
“We should be concerned but I think we have to stop being surprised about this,” says Sam Ransbotham, Assistant Professor of Information Systems at Boston College. “Many many companies are storing lots and lots of information. We are giving that information up in exchange for newer services, whatever we want from the website, so we’ve given the information up. We can’t be too surprised when, given the number of sites that have this information, they get attacked. This will continue to happen.”
EBay says the hackers used stolen employee log-in credentials to access a customer information database between late February and early March. EBay discovered the security breach about two weeks ago and today began alerting customers to change their passwords.
“Whenever anything like this happens, a race starts between the bad guys trying to use this information and the good guys trying to get counter measures in place,” says Ransbotham, whose research centers around information technology security. “EBay has been doing the right thing in getting information out to people who can take counter measures for that.”
While the personal data the company’s 145 million members are at risk, no financial information was accessed. Still, the loss of an unknown number of passwords has the potential to compromise all websites.
“If you’re using the same password at multiple sites, those sites are available for compromise as well,” says Ransbotham, who co-authored the research paper, “Choice and Chance: A Conceptual Model of Paths to Information Security Compromise” (Information Systems Research). “If your banking website lets you recover your password through information about your hometown or your high school mascot, then that information may be victim, too.”
As eBay scrambled to contain the damage and preserve its reputation among customers, experts like Ransbotham say attacks like this are the new normal.
“The potential for this is everywhere. We can’t expect technical panaceas. We can’t expect that security will be perfect everywhere. There’s no reason to believe that other sites will not have similar problems. Anytime that a website is successful, or an e-commerce site is successful, it’s going to have a large amount of data and that large amount of data will provide the incentive necessary for attackers to go after it. So we can’t be surprised when this is happening - we just need to be ready when it does. I think eBay has gone through this disaster planning scenario before and they’re putting the processes in place.”
